SeleniumBase Example


▢️ How is SeleniumBase different from raw Selenium? (click to expand)

πŸ’‘ SeleniumBase is a Python test framework for the Selenium/WebDriver browser automation library. This framework incorporates test-runners such as pytest, nosetests, and behave to provide organized structure, test discovery, test execution, test state (eg. passed, failed, or skipped), and command-line options for changing default settings (such as choosing the browser to use). With raw Selenium, you would need to set up your own options-parser for configuring tests from the command-line.

πŸ’‘ With raw Selenium, you have to manually download drivers (eg. chromedriver) before running tests. With SeleniumBase's driver manager, that's done automatically for you if the required driver isn't already on your PATH. There are also console scripts available for more control (eg. sbase get chromedriver latest to download the latest version of chromedriver to a local SeleniumBase directory).

πŸ’‘ With raw Selenium, commands that use selectors need to specify the type of selector (eg. "css selector", "button#myButton"). With SeleniumBase, there's auto-detection between CSS Selectors and XPath, which means you don't need to specify the type of selector in your commands (but optionally you could).

πŸ’‘ SeleniumBase methods often perform multiple actions in a single method call. For example, self.type(selector,text) does the following:
1. Waits for the element to be visible.
2. Waits for the element to be interactive.
3. Clears the text field.
4. Types in the new text.
5. Presses Enter/Submit if the text ends in "\n".
With raw Selenium, those actions require multiple method calls.

πŸ’‘ SeleniumBase uses default timeout values when not set, which means that methods automatically wait for elements to appear (up to the timeout limit) before failing:
βœ…self.click("button")
With raw Selenium, methods would fail instantly (by default) if an element needed more time to load:
❌self.driver.find_element(by="css selector", value="button").click()
(Reliable code is better than unreliable code.)

πŸ’‘ SeleniumBase lets you change the explicit timeout values of methods:
βœ…self.click("button",timeout=10)
With raw Selenium, that requires more code:
❌WebDriverWait(driver,10).until(EC.element_to_be_clickable("css selector", "button")).click()
(Simple code is better than complex code.)

πŸ’‘ SeleniumBase gives you clean error output when a test fails. With raw Selenium, error messages can get very messy.

πŸ’‘ SeleniumBase gives you the option to generate a dashboard and reports for tests. It also saves screenshots from failing tests to the ./latest_logs/ folder. Raw Selenium does not have these options out-of-the-box.

πŸ’‘ SeleniumBase includes desktop GUI apps for running tests, such as SeleniumBase Commander for pytest, and SeleniumBase Behave GUI.

πŸ’‘ SeleniumBase has its own Recorder & Test Generator that can create tests from manual browser actions. SeleniumBase also has many other useful tools and console scripts for getting things done quickly. (See the documentation for more details!)


Here's a 2FA/MFA app that can be tested with SeleniumBase:

SeleniumBase MFA Demo App

Here are a few scripts to test that app with SeleniumBase:

πŸ“˜πŸ“ An example test with the BaseCase class. Runs with pytest or nosetests. (Learn more)

from seleniumbase import BaseCase

class TestMFALogin(BaseCase):
    def test_mfa_login(self):
        self.open("https://seleniumbase.io/realworld/login")
        self.type("#username", "demo_user")
        self.type("#password", "secret_pass")
        self.enter_mfa_code("#totpcode", "GAXG2MTEOR3DMMDG")  # 6-digit
        self.assert_exact_text("Welcome!", "h1")
        self.assert_element("img#image1")
        self.click('a:contains("This Page")')
        self.save_screenshot_to_logs()

πŸ“—πŸ“ An example test with the sb pytest fixture. Runs with pytest.

def test_mfa_login(sb):
    sb.open("https://seleniumbase.io/realworld/login")
    sb.type("#username", "demo_user")
    sb.type("#password", "secret_pass")
    sb.enter_mfa_code("#totpcode", "GAXG2MTEOR3DMMDG")  # 6-digit

    sb.assert_element("img#image1")
    sb.click('a:contains("This Page")')
    sb.save_screenshot_to_logs()

πŸ“™πŸ“ An example test with the SB Context Manager. Runs with pure python.

from seleniumbase import SB

with SB() as sb:  # By default, browser="chrome" if not set.
    sb.open("https://seleniumbase.github.io/realworld/login")
    sb.type("#username", "demo_user")
    sb.type("#password", "secret_pass")
    sb.enter_mfa_code("#totpcode", "GAXG2MTEOR3DMMDG")  # 6-digit
    sb.assert_text("Welcome!", "h1")
    sb.highlight("img#image1")  # A fancier assert_element() call
    sb.click('a:contains("This Page")')  # Use :contains() on any tag
    sb.click_link("Sign out")  # Link must be "a" tag. Not "button".
    sb.assert_element('a:contains("Sign in")')
    sb.assert_exact_text("You have been signed out!", "#top_message")

πŸ“•πŸ“ An example test with behave-BDD Gherkin structure. Runs with behave. (Learn more)

Downloading web drivers:

βœ… SeleniumBase automatically downloads web drivers as needed, such as chromedriver, edgedriver, and geckodriver.

βœ… To manually download a webdriver, see Console Scripts OR Webdriver Installation.

Basic Example & Usage:

πŸ”΅ If you’ve cloned SeleniumBase, you can run tests from the examples/ folder.

Here's my_first_test.py:

cd examples/
pytest my_first_test.py

(Uses --chrome by default.)

SeleniumBase Test

Here's the code for my_first_test.py:

from seleniumbase import BaseCase

class MyTestClass(BaseCase):
    def test_swag_labs(self):
        self.open("https://www.saucedemo.com")
        self.type("#user-name", "standard_user")
        self.type("#password", "secret_sauce\n")
        self.assert_element("div.inventory_list")
        self.assert_text("PRODUCTS", "span.title")
        self.click('button[name*="backpack"]')
        self.click("#shopping_cart_container a")
        self.assert_text("YOUR CART", "span.title")
        self.assert_text("Backpack", "div.cart_item")
        self.click("button#checkout")
        self.type("#first-name", "SeleniumBase")
        self.type("#last-name", "Automation")
        self.type("#postal-code", "77123")
        self.click("input#continue")
        self.assert_text("CHECKOUT: OVERVIEW")
        self.assert_text("Backpack", "div.cart_item")
        self.click("button#finish")
        self.assert_exact_text("THANK YOU FOR YOUR ORDER", "h2")
        self.assert_element('img[alt="Pony Express"]')
        self.js_click("a#logout_sidebar_link")
        self.assert_element("div#login_button_container")

Here are some common SeleniumBase methods that you might find in tests:

Fun Facts / Learn More:

βœ… SeleniumBase automatically handles common WebDriver actions such as launching web browsers before tests, saving screenshots during failures, and closing web browsers after tests.

βœ… SeleniumBase lets you customize test runs from the command-line.

βœ… SeleniumBase uses simple syntax for commands. Example:

self.type("input", "dogs\n")

SeleniumBase tests can be run with pytest or nosetests. (There’s also a behave BDD format.)

pytest my_first_test.py --chrome

nosetests test_suite.py --firefox

βœ… pytest includes automatic test discovery. If you don't specify a specific file or folder to run, pytest will automatically search through all subdirectories for tests to run based on the following criteria:

With a SeleniumBase pytest.ini file present, you can modify default discovery settings. The Python class name can be anything because seleniumbase.BaseCase inherits unittest.TestCase, which triggers autodiscovery.

βœ… You can do a pre-flight check to see which tests would get discovered by pytest before the real flight:

pytest --collect-only -q

βœ… You can be more specific when calling pytest on a file:

pytest [FILE_NAME.py]::[CLASS_NAME]::[METHOD_NAME]

nosetests [FILE_NAME.py]:[CLASS_NAME].[METHOD_NAME]

βœ… No More Flaky Tests! SeleniumBase methods automatically wait for page elements to finish loading before interacting with them (up to a timeout limit). This means you no longer need random time.sleep() statements in your scripts.

NO MORE FLAKY TESTS!

βœ… SeleniumBase supports all major browsers and operating systems:

Browsers: Chrome, Edge, Firefox, and Safari.

Systems: Linux/Ubuntu, macOS, and Windows.

βœ… SeleniumBase works on all popular CI/CD platforms:

GitHub Actions integration Jenkins integration Azure integration Google Cloud integration AWS integration Your Computer

βœ… SeleniumBase includes an automated/manual hybrid solution called MasterQA, which speeds up manual testing by having automation perform all the browser actions while the manual tester handles validation.

Detailed Instructions:

πŸ”΅ Demo Mode helps you see what a test is doing. If a test is moving too fast for your eyes, run it in Demo Mode, which pauses the browser briefly between actions, highlights page elements being acted on, and displays assertions:

pytest my_first_test.py --demo

πŸ”΅ You can use the following calls in your scripts to help you debug issues:

import time; time.sleep(5)  # Makes the test wait and do nothing for 5 seconds.
import pdb; pdb.set_trace()  # Enter debugging mode. n = next, c = continue, s = step.
import pytest; pytest.set_trace()  # Enter debugging mode. n = next, c = continue, s = step.

πŸ”΅ To pause an active test that throws an exception or error, (and keep the browser window open while Debug Mode begins in the console), add --pdb as a pytest option:

pytest my_first_test.py --pdb

(pdb console commands: n, c, s => next, continue, step).

πŸ”΅ Here are some useful command-line options that come with pytest:

-v  # Verbose mode. Prints the full name of each test run.
-q  # Quiet mode. Print fewer details in the console output when running tests.
-x  # Stop running the tests after the first failure is reached.
--html=report.html  # Creates a detailed pytest-html report after tests finish.
--collect-only | --co  # Show what tests would get run. (Without running them)
-n=NUM  # Multithread the tests using that many threads. (Speed up test runs!)
-s  # See print statements. (Should be on by default with pytest.ini present.)
--junit-xml=report.xml  # Creates a junit-xml report after tests finish.
--pdb  # If a test fails, enter Post Mortem Debug Mode. (Don't use with CI!)
--trace  # Enter Debug Mode at the beginning of each test. (Don't use with CI!)
-m=MARKER  # Run tests with the specified pytest marker.

(See the full list of command-line option definitions here. For detailed examples of command-line options, see customizing_test_runs.md)

πŸ”΅ During test failures, logs and screenshots from the most recent test run will get saved to the latest_logs/ folder. Those logs will get moved to archived_logs/ if you add –archive_logs to command-line options, or have ARCHIVE_EXISTING_LOGS set to True in settings.py, otherwise log files with be cleaned up at the start of the next test run. The test_suite.py collection contains tests that fail on purpose so that you can see how logging works.

cd examples/

pytest test_suite.py --browser=chrome

pytest test_suite.py --browser=firefox

An easy way to override seleniumbase/config/settings.py is by using a custom settings file. Here’s the command-line option to add to tests: (See examples/custom_settings.py) --settings_file=custom_settings.py (Settings include default timeout values, a two-factor auth key, DB credentials, S3 credentials, and other important settings used by tests.)

πŸ”΅ To pass additional data from the command-line to tests, add --data="ANY STRING". Inside your tests, you can use self.data to access that.

Test Directory Configuration:

πŸ”΅ When running tests with pytest, you’ll want a copy of pytest.ini in your root folders. When running tests with nosetests, you’ll want a copy of setup.cfg in your root folders. These files specify default configuration details for tests. Folders should also include a blank __init__.py file, which allows your tests to import files from that folder.

πŸ”΅ sbase mkdir DIR creates a folder with config files and sample tests:

sbase mkdir ui_tests

That new folder will have these files:

ui_tests/
β”œβ”€β”€ __init__.py
β”œβ”€β”€ my_first_test.py
β”œβ”€β”€ parameterized_test.py
β”œβ”€β”€ pytest.ini
β”œβ”€β”€ requirements.txt
β”œβ”€β”€ setup.cfg
β”œβ”€β”€ test_demo_site.py
└── boilerplates/
    β”œβ”€β”€ __init__.py
    β”œβ”€β”€ base_test_case.py
    β”œβ”€β”€ boilerplate_test.py
    β”œβ”€β”€ classic_obj_test.py
    β”œβ”€β”€ page_objects.py
    β”œβ”€β”€ sb_fixture_test.py
    └── samples/
        β”œβ”€β”€ __init__.py
        β”œβ”€β”€ google_objects.py
        β”œβ”€β”€ google_test.py
        β”œβ”€β”€ sb_swag_test.py
        └── swag_labs_test.py

ProTipβ„’: You can also create a boilerplate folder without any sample tests in it by adding -b or --basic to the sbase mkdir command:

sbase mkdir ui_tests --basic

That new folder will have these files:

ui_tests/
β”œβ”€β”€ __init__.py
β”œβ”€β”€ pytest.ini
β”œβ”€β”€ requirements.txt
└── setup.cfg

Of those files, the pytest.ini config file is the most important, followed by a blank __init__.py file. There’s also a setup.cfg file (only needed for nosetests). Finally, the requirements.txt file can be used to help you install seleniumbase into your environments (if it’s not already installed).


Log files from failed tests:

Let’s try an example of a test that fails:

""" test_fail.py """
from seleniumbase import BaseCase

class MyTestClass(BaseCase):

    def test_find_army_of_robots_on_xkcd_desert_island(self):
        self.open("https://xkcd.com/731/")
        self.assert_element("div#ARMY_OF_ROBOTS", timeout=1)  # This should fail

You can run it from the examples/ folder like this:

pytest test_fail.py

πŸ”΅ You’ll notice that a logs folder, β€œlatest_logs”, was created to hold information about the failing test, and screenshots. During test runs, past results get moved to the archived_logs folder if you have ARCHIVE_EXISTING_LOGS set to True in settings.py, or if your run tests with --archive-logs. If you choose not to archive existing logs, they will be deleted and replaced by the logs of the latest test run.


The SeleniumBase Dashboard:

πŸ”΅ The --dashboard option for pytest generates a SeleniumBase Dashboard located at dashboard.html, which updates automatically as tests run and produce results. Example:

pytest --dashboard --rs --headless

The SeleniumBase Dashboard

πŸ”΅ Additionally, you can host your own SeleniumBase Dashboard Server on a port of your choice. Here’s an example of that using Python 3’s http.server:

python -m http.server 1948

πŸ”΅ Now you can navigate to http://localhost:1948/dashboard.html in order to view the dashboard as a web app. This requires two different terminal windows: one for running the server, and another for running the tests, which should be run from the same directory. (Use CTRL+C to stop the http server.)

πŸ”΅ Here’s a full example of what the SeleniumBase Dashboard may look like:

pytest test_suite.py --dashboard --rs --headless

The SeleniumBase Dashboard


Generating Test Reports:

Pytest Reports:

πŸ”΅ Using --html=report.html gives you a fancy report of the name specified after your test suite completes.

pytest test_suite.py --html=report.html

Example Pytest Report

πŸ”΅ When combining pytest html reports with SeleniumBase Dashboard usage, the pie chart from the Dashboard will get added to the html report. Additionally, if you set the html report URL to be the same as the Dashboard URL when also using the dashboard, (example: --dashboard --html=dashboard.html), then the Dashboard will become an advanced html report when all the tests complete.

πŸ”΅ Here’s an example of an upgraded html report:

pytest test_suite.py --dashboard --html=report.html

Dashboard Pytest HTML Report

If viewing pytest html reports in Jenkins, you may need to configure Jenkins settings for the html to render correctly. This is due to Jenkins CSP changes.

You can also use --junit-xml=report.xml to get an xml report instead. Jenkins can use this file to display better reporting for your tests.

pytest test_suite.py --junit-xml=report.xml

Nosetest Reports:

The --report option gives you a fancy report after your test suite completes.

nosetests test_suite.py --report

Example Nosetest Report

(NOTE: You can add --show-report to immediately display Nosetest reports after the test suite completes. Only use --show-report when running tests locally because it pauses the test run.)

Behave Dashboard & Reports:

(The behave_bdd/ folder can be found in the examples/ folder.)

behave behave_bdd/features/ -D dashboard -D headless

You can also use --junit to get .xml reports for each Behave feature. Jenkins can use these files to display better reporting for your tests.

behave behave_bdd/features/ --junit -D rs -D headless

Allure Reports:

See: https://docs.qameta.io/allure/

SeleniumBase no longer includes allure-pytest as part of installed dependencies. If you want to use it, install it first:

pip install allure-pytest

Now your tests can create Allure results files, which can be processed by Allure Reports.

pytest test_suite.py --alluredir=allure_results

Using a Proxy Server:

If you wish to use a proxy server for your browser tests (Chromium or Firefox), you can add --proxy=IP_ADDRESS:PORT as an argument on the command line.

pytest proxy_test.py --proxy=IP_ADDRESS:PORT

If the proxy server that you wish to use requires authentication, you can do the following (Chromium only):

pytest proxy_test.py --proxy=USERNAME:PASSWORD@IP_ADDRESS:PORT

SeleniumBase also supports SOCKS4 and SOCKS5 proxies:

pytest proxy_test.py --proxy="socks4://IP_ADDRESS:PORT"

pytest proxy_test.py --proxy="socks5://IP_ADDRESS:PORT"

To make things easier, you can add your frequently-used proxies to PROXY_LIST in proxy_list.py, and then use --proxy=KEY_FROM_PROXY_LIST to use the IP_ADDRESS:PORT of that key.

pytest proxy_test.py --proxy=proxy1

Changing the User-Agent:

πŸ”΅ If you wish to change the User-Agent for your browser tests (Chromium and Firefox only), you can add --agent="USER AGENT STRING" as an argument on the command-line.

pytest user_agent_test.py --agent="Mozilla/5.0 (Nintendo 3DS; U; ; en) Version/1.7412.EU"

Handling Pop-Up / Pop Up Alerts:

πŸ”΅ self.accept_alert() automatically waits for and accepts alert pop-ups. self.dismiss_alert() automatically waits for and dismisses alert pop-ups. On occasion, some methods like self.click(SELECTOR) might dismiss a pop-up on its own because they call JavaScript to make sure that the readyState of the page is complete before advancing. If you’re trying to accept a pop-up that got dismissed this way, use this workaround: Call self.find_element(SELECTOR).click() instead, (which will let the pop-up remain on the screen), and then use self.accept_alert() to accept the pop-up (more on that here). If pop-ups are intermittent, wrap code in a try/except block.

Building Guided Tours for Websites:

πŸ”΅ Learn about SeleniumBase Interactive Walkthroughs (in the examples/tour_examples/ folder). It’s great for prototyping a website onboarding experience.


Production Environments & Integrations:

▢️ Here are some things you can do to set up a production environment for your testing. (click to expand) Here's an example of running tests with some additional features enabled: ```bash pytest [YOUR_TEST_FILE.py] --with-db-reporting --with-s3-logging ```

Detailed Method Specifications and Examples:

πŸ”΅ Navigating to a web page: (and related commands)

self.open("https://xkcd.com/378/")  # This method opens the specified page.

self.go_back()  # This method navigates the browser to the previous page.

self.go_forward()  # This method navigates the browser forward in history.

self.refresh_page()  # This method reloads the current page.

self.get_current_url()  # This method returns the current page URL.

self.get_page_source()  # This method returns the current page source.

ProTipβ„’: You can use the self.get_page_source() method with Python’s find() command to parse through HTML to find something specific. (For more advanced parsing, see the BeautifulSoup example.)

source = self.get_page_source()
head_open_tag = source.find('<head>')
head_close_tag = source.find('</head>', head_open_tag)
everything_inside_head = source[head_open_tag+len('<head>'):head_close_tag]

πŸ”΅ Clicking:

To click an element on the page:

self.click("div#my_id")

ProTipβ„’: In most web browsers, you can right-click on a page and select Inspect Element to see the CSS selector details that you’ll need to create your own scripts.

πŸ”΅ Typing Text:

self.type(selector, text) # updates the text from the specified element with the specified value. An exception is raised if the element is missing or if the text field is not editable. Example:

self.type("input#id_value", "2012")

You can also use self.add_text() or the WebDriver .send_keys() command, but those won’t clear the text box first if there’s already text inside.

πŸ”΅ Getting the text from an element on a page:

text = self.get_text("header h2")

πŸ”΅ Getting the attribute value from an element on a page:

attribute = self.get_attribute("#comic img", "title")

πŸ”΅ Asserting existence of an element on a page within some number of seconds:

self.wait_for_element_present("div.my_class", timeout=10)

(NOTE: You can also use: self.assert_element_present(ELEMENT))

πŸ”΅ Asserting visibility of an element on a page within some number of seconds:

self.wait_for_element_visible("a.my_class", timeout=5)

(NOTE: The short versions of that are self.find_element(ELEMENT) and self.assert_element(ELEMENT). The find_element() version returns the element.)

Since the line above returns the element, you can combine that with .click() as shown below:

self.find_element("a.my_class", timeout=5).click()

# But you're better off using the following statement, which does the same thing:

self.click("a.my_class")  # DO IT THIS WAY!

ProTipβ„’: You can use dots to signify class names (Ex: div.class_name) as a simplified version of div[class="class_name"] within a CSS selector.

You can also use *= to search for any partial value in a CSS selector as shown below:

self.click('a[name*="partial_name"]')

πŸ”΅ Asserting visibility of text inside an element on a page within some number of seconds:

self.assert_text("Make it so!", "div#trek div.picard div.quotes")
self.assert_text("Tea. Earl Grey. Hot.", "div#trek div.picard div.quotes", timeout=3)

(NOTE: self.find_text(TEXT, ELEMENT) and self.wait_for_text(TEXT, ELEMENT) also do this. For backwards compatibility, older method names were kept, but the default timeout may be different.)

πŸ”΅ Asserting Anything:

self.assert_true(var1 == var2)

self.assert_false(var1 == var2)

self.assert_equal(var1, var2)

πŸ”΅ Useful Conditional Statements: (with creative examples)

❓ is_element_visible(selector): (visible on the page)

if self.is_element_visible('div#warning'):
    print("Red Alert: Something bad might be happening!")

❓ is_element_present(selector): (present in the HTML)

if self.is_element_present('div#top_secret img.tracking_cookie'):
    self.contact_cookie_monster()  # Not a real SeleniumBase method
else:
    current_url = self.get_current_url()
    self.contact_the_nsa(url=current_url, message="Dark Zone Found")  # Not a real SeleniumBase method
def is_there_a_cloaked_klingon_ship_on_this_page():
    if self.is_element_present("div.ships div.klingon"):
        return not self.is_element_visible("div.ships div.klingon")
    return False

❓ is_text_visible(text, selector): (text visible on element)

if self.is_text_visible("You Shall Not Pass!", "h1"):
    self.open("https://www.youtube.com/watch?v=3xYXUeSmb-Y")
▢️ Click for a longer example of is_text_visible(): ```python def get_mirror_universe_captain_picard_superbowl_ad(superbowl_year): selector = "div.superbowl_%s div.commercials div.transcript div.picard" % superbowl_year if self.is_text_visible("Yes, it was I who summoned you all here.", selector): return "Picard Paramount+ Superbowl Ad 2020" elif self.is_text_visible("Commander, signal the following: Our Network is Secure!"): return "Picard Mirror Universe iboss Superbowl Ad 2018" elif self.is_text_visible("For the Love of Marketing and Earl Grey Tea!", selector): return "Picard Mirror Universe HubSpot Superbowl Ad 2015" elif self.is_text_visible("Delivery Drones... Engage", selector): return "Picard Mirror Universe Amazon Superbowl Ad 2015" elif self.is_text_visible("Bing it on Screen!", selector): return "Picard Mirror Universe Microsoft Superbowl Ad 2015" elif self.is_text_visible("OK Glass, Make it So!", selector): return "Picard Mirror Universe Google Superbowl Ad 2015" elif self.is_text_visible("Number One, I've Never Seen Anything Like It.", selector): return "Picard Mirror Universe Tesla Superbowl Ad 2015" elif self.is_text_visible("Let us make sure history never forgets the name ... Facebook", selector): return "Picard Mirror Universe Facebook Superbowl Ad 2015" elif self.is_text_visible("""With the first link, the chain is forged. The first speech censored, the first thought forbidden, the first freedom denied, chains us all irrevocably.""", selector): return "Picard Mirror Universe Wikimedia Superbowl Ad 2015" else: raise Exception("Reports of my assimilation are greatly exaggerated.") ```

❓ is_link_text_visible(link_text):

if self.is_link_text_visible("Stop! Hammer time!"):
    self.click_link("Stop! Hammer time!")

πŸ”΅ Switching Tabs:

If your test opens up a new tab/window, you can switch to it. (SeleniumBase automatically switches to new tabs that don't open to about:blank URLs.)

self.switch_to_window(1)  # This switches to the new tab (0 is the first one)

πŸ”΅ ProTipβ„’: iframes follow the same principle as new windows - you need to specify the iframe if you want to take action on something in there

self.switch_to_frame('ContentManagerTextBody_ifr')
# Now you can act inside the iframe
# .... Do something cool (here)
self.switch_to_default_content()  # Exit the iframe when you're done

πŸ”΅ Executing Custom jQuery Scripts:

jQuery is a powerful JavaScript library that allows you to perform advanced actions in a web browser. If the web page you're on already has jQuery loaded, you can start executing jQuery scripts immediately. You'd know this because the web page would contain something like the following in the HTML:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>

πŸ”΅ It’s OK if you want to use jQuery on a page that doesn’t have it loaded yet. To do so, run the following command first:

self.activate_jquery()
▢️ Here are some examples of using jQuery in your scripts. (click to expand) ```python self.execute_script("jQuery, window.scrollTo(0, 600)") # Scrolling the page self.execute_script("jQuery('#annoying-widget').hide()") # Hiding elements on a page self.execute_script("jQuery('#hidden-widget').show(0)") # Showing hidden elements on a page self.execute_script("jQuery('#annoying-button a').remove()") # Removing elements on a page self.execute_script("jQuery('%s').mouseover()" % (mouse_over_item)) # Mouse-over elements on a page self.execute_script("jQuery('input#the_id').val('my_text')") # Fast text input on a page self.execute_script("jQuery('div#dropdown a.link').click()") # Click elements on a page self.execute_script("return jQuery('div#amazing')[0].text") # Returns the css "text" of the element given self.execute_script("return jQuery('textarea')[2].value") # Returns the css "value" of the 3rd textarea element on the page ``` (Most of the above commands can be done directly with built-in SeleniumBase methods.)

πŸ”΅ Some websites have a restrictive Content Security Policy to prevent users from loading jQuery and other external libraries onto their websites. If you need to use jQuery or another JS library on such a website, add --disable-csp on the command-line.

▢️ In this example, JavaScript creates a referral button on a page, which is then clicked. (click to expand) ```python start_page = "https://xkcd.com/465/" destination_page = "https://github.com/seleniumbase/SeleniumBase" self.open(start_page) referral_link = '''Free-Referral Button!''' % destination_page self.execute_script('''document.body.innerHTML = \"%s\"''' % referral_link) self.click("a.analytics") # Clicks the generated button ``` (Due to popular demand, this traffic generation example has been included in SeleniumBase with the self.generate_referral(start_page, end_page) and the self.generate_traffic(start_page, end_page, loops) methods.)

πŸ”΅ Using deferred asserts:

Let's say you want to verify multiple different elements on a web page in a single test, but you don't want the test to fail until you verified several elements at once so that you don't have to rerun the test to find more missing elements on the same page. That's where deferred asserts come in. Here's the example:

from seleniumbase import BaseCase

class MyTestClass(BaseCase):

    def test_deferred_asserts(self):
        self.open('https://xkcd.com/993/')
        self.wait_for_element('#comic')
        self.deferred_assert_element('img[alt="Brand Identity"]')
        self.deferred_assert_element('img[alt="Rocket Ship"]')  # Will Fail
        self.deferred_assert_element('#comicmap')
        self.deferred_assert_text('Fake Item', '#middleContainer')  # Will Fail
        self.deferred_assert_text('Random', '#middleContainer')
        self.deferred_assert_element('a[name="Super Fake !!!"]')  # Will Fail
        self.process_deferred_asserts()

deferred_assert_element() and deferred_assert_text() will save any exceptions that would be raised. To flush out all the failed deferred asserts into a single exception, make sure to call self.process_deferred_asserts() at the end of your test method. If your test hits multiple pages, you can call self.process_deferred_asserts() before navigating to a new page so that the screenshot from your log files matches the URL where the deferred asserts were made.

πŸ”΅ Accessing Raw WebDriver:

If you need access to any commands that come with standard WebDriver, you can call them directly like this:

self.driver.delete_all_cookies()
capabilities = self.driver.capabilities
self.driver.find_elements("partial link text", "GitHub")

(In general, you’ll want to use the SeleniumBase versions of methods when available.)

πŸ”΅ Retrying failing tests automatically:

You can use --reruns=NUM to retry failing tests that many times. Use --reruns-delay=SECONDS to wait that many seconds between retries. Example:

pytest --reruns=1 --reruns-delay=1

You can use the @retry_on_exception() decorator to retry failing methods. (First import: from seleniumbase import decorators). To learn more about SeleniumBase decorators, click here.
