A complete framework for web/mobile automation, end-to-end testing, and [website tours](https://github.com/seleniumbase/SeleniumBase/blob/master/examples/tour_examples/ReadMe.md). SeleniumBase uses [pytest](https://docs.pytest.org/en/latest/index.html) for running Python scripts, while using [Selenium WebDriver](https://selenium.dev/) for controlling web browsers.
(Above: [my_first_test.py](https://github.com/seleniumbase/SeleniumBase/blob/master/examples/my_first_test.py) from [examples/](https://github.com/seleniumbase/SeleniumBase/tree/master/examples) running in Demo Mode, which adds JavaScript for highlighting page actions.)
```bash
pytest my_first_test.py --demo
```
## Features:

## Quick Start
(Requires [Git](https://git-scm.com/) and [Python](https://www.python.org/downloads/). Optionally, you may want to use a [Python virtual environment](https://github.com/seleniumbase/SeleniumBase/blob/master/help_docs/virtualenv_instructions.md) to isolate Python dependencies between projects.)
#### Upgrade [pip](https://pypi.org/project/pip/) and [setuptools](https://pypi.org/project/setuptools/):
```bash
python -m pip install -U pip setuptools
```
### Install ``seleniumbase``:
```bash
pip install seleniumbase
```
* Add ``--upgrade`` OR ``-U`` to upgrade an installation.
* Add ``--force-reinstall`` for a clean install.
You can also install seleniumbase from a ``git clone``:
```bash
git clone https://github.com/seleniumbase/SeleniumBase.git
cd SeleniumBase/
pip install -r requirements.txt
python setup.py install
```
If multiple versions of Python are installed, be specific (E.g. use ``python3`` instead of ``python``).
### Download a webdriver:
SeleniumBase can download a webdriver to the [seleniumbase/drivers](https://github.com/seleniumbase/SeleniumBase/tree/master/seleniumbase/drivers) folder with the ``install`` command:
```bash
seleniumbase install chromedriver
```
* You need a different webdriver for each web browser you want to run automation on: ``chromedriver`` for Chrome, ``edgedriver`` for Edge, ``geckodriver`` for Firefox, ``operadriver`` for Opera, and ``iedriver`` for Internet Explorer.
* If you have the latest version of Chrome installed, get the latest chromedriver (otherwise it defaults to chromedriver 2.44 for compatibility reasons):
```bash
seleniumbase install chromedriver latest
```
### Run a test on Chrome:
```bash
cd examples/
pytest my_first_test.py
```
* Chrome is the default browser if not specified with ``--browser=BROWSER``.
* On Linux ``--headless`` is the default behavior (running with no GUI). You can also run in headless mode on any OS. If your Linux machine has a GUI and you want to see the web browser as tests run, add ``--headed`` or ``--gui``.
**Check out [my_first_test.py](https://github.com/seleniumbase/SeleniumBase/blob/master/examples/my_first_test.py) to see what a simple test looks like:**
* By default, [CSS Selectors](https://www.w3schools.com/cssref/css_selectors.asp) are used for finding page elements.
* Here are some common SeleniumBase methods you might find in tests:
```python
self.open(URL) # Navigate to the web page
self.click(SELECTOR) # Click a page element
self.update_text(SELECTOR, TEXT) # Type text (Add "\n" to text for pressing enter/return.)
self.assert_element(SELECTOR) # Assert element is visible
self.assert_text(TEXT) # Assert text is visible (has optional SELECTOR arg)
self.assert_title(PAGE_TITLE) # Assert page title
self.assert_no_404_errors() # Assert no 404 errors from files on the page
self.assert_no_js_errors() # Assert no JavaScript errors on the page (Chrome-ONLY)
self.execute_script(JAVASCRIPT) # Execute javascript code
self.go_back() # Navigate to the previous URL
self.get_text(SELECTOR) # Get text from a selector
self.get_attribute(SELECTOR, ATTRIBUTE) # Get a specific attribute from a selector
self.is_element_visible(SELECTOR) # Determine if an element is visible on the page
self.is_text_visible(TEXT) # Determine if text is visible on the page (optional SELECTOR)
self.hover_and_click(HOVER_SELECTOR, CLICK_SELECTOR) # Mouseover element & click another
self.select_option_by_text(DROPDOWN_SELECTOR, OPTION_TEXT) # Select a dropdown option
self.switch_to_frame(FRAME_NAME) # Switch webdriver control to an iframe on the page
self.switch_to_default_content() # Switch webdriver control out of the current iframe
self.switch_to_window(WINDOW_NUMBER) # Switch to a different window/tab
self.save_screenshot(FILE_NAME) # Save a screenshot of the current page
```

## Learn More:
#### **Automatic WebDriver abilities:**
SeleniumBase automatically handles common WebDriver actions such as spinning up web browsers and saving screenshots during test failures. ([Read more about customizing test runs](https://github.com/seleniumbase/SeleniumBase/blob/master/help_docs/customizing_test_runs.md).)
#### **Simplified code:**
SeleniumBase uses simple syntax for commands, such as:
```python
self.update_text("input", "dogs\n")
```
The same command with regular WebDriver is very messy:
(And it doesn't include SeleniumBase smart-waiting.)
```python
self.driver.find_element_by_css_selector("input").clear() # Not always needed
self.driver.find_element_by_css_selector("input").send_keys("dogs")
self.driver.find_element_by_css_selector("input").submit()
```
(You can still use ``self.driver`` in your code.)
#### **Run tests with ``pytest`` or ``nosetests`` in any browser:**
(Using **pytest** is recommended. **Chrome** is the default browser.)
```bash
pytest my_first_test.py --browser=chrome
nosetests test_suite.py --browser=firefox
```
All Python methods that start with ``test_`` will automatically be run when using ``pytest`` or ``nosetests`` on a Python file, (or on folders containing Python files). You can also be more specific on what to run within a file by using the following: (Note that the syntax is different for pytest vs nosetests.)
```bash
pytest [FILE_NAME].py::[CLASS_NAME]::[METHOD_NAME]
nosetests [FILE_NAME].py:[CLASS_NAME].[METHOD_NAME]
```
#### **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.
#### **Automated/manual hybrid mode:**
SeleniumBase includes a solution called **[MasterQA](https://github.com/seleniumbase/SeleniumBase/blob/master/seleniumbase/masterqa/ReadMe.md)**, which speeds up manual testing by having automation perform all the browser actions while the manual tester handles validatation.

## Detailed Instructions:
**Here's how to run the example script on various web browsers:**
First install a webdriver for each browser you intend to use:
```bash
seleniumbase install chromedriver
seleniumbase install geckodriver
seleniumbase install edgedriver
seleniumbase install iedriver
seleniumbase install operadriver
```
Next, choose between **pytest** and **nosetests** test runners. (Mostly interchangeable.)
```bash
cd examples/
pytest my_first_test.py --browser=chrome
nosetests my_first_test.py --browser=firefox
```
(If no browser is specified, Chrome is used by default.)
With Pytest, a green dot means a test passed. An "F" means a test failed.
**Use Demo Mode to help you see what tests are asserting.**
If the example test is moving too fast for your eyes, you can run it in **Demo Mode** by adding ``--demo`` on the command-line, which pauses the browser briefly between actions, highlights page elements being acted on, and lets you know what test assertions are happening in real time:
```bash
pytest my_first_test.py --demo
```
**Pytest** includes test discovery. If you don't specify a specific file or folder to run from, ``pytest`` will search all subdirectories automatically for tests to run based on the following matching criteria:
Python filenames that start with ``test_`` or end with ``_test.py``.
Python methods that start with ``test_``.
The Python class name can be anything since SeleniumBase's ``BaseCase`` class inherits from the ``unittest.TestCase`` class.
You can see which tests are getting discovered by ``pytest`` by using:
```bash
pytest --collect-only -q
```
You can use the following in your scripts to help you debug issues:
(If using ipdb, make sure you add "-s" to command-line options unless already in pytest.ini)
```python
import time; time.sleep(5) # Makes the test wait and do nothing for 5 seconds.
import ipdb; ipdb.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.
```
**To pause an active test that throws an exception or error, add ``--pdb -s``:**
```bash
pytest my_first_test.py --pdb -s
```
The code above will leave your browser window open in case there's a failure. (ipdb commands: 'n', 'c', 's' => next, continue, step).
Here are some other useful command-line options that come with Pytest:
```bash
-v # Prints the full test name for each test.
-q # Prints 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 # Show what tests would get run without actually running them.
-s # See print statements. (Should be on by default with pytest.ini present.)
-n=NUM # Multithread the tests using that many threads. (Speed up test runs!)
```
SeleniumBase provides additional Pytest command-line options for tests:
```bash
--browser=BROWSER # (The web browser to use.)
--cap-file=FILE # (The web browser's desired capabilities to use.)
--settings-file=FILE # (Overrides SeleniumBase settings.py values.)
--env=ENV # (Set a test environment. Use "self.env" to use this in tests.)
--data=DATA # (Extra data to pass to tests. Use "self.data" in tests.)
--user-data-dir=DIR # (Set the Chrome user data directory to use.)
--server=SERVER # (The server / IP address used by the tests.)
--port=PORT # (The port that's used by the test server.)
--proxy=SERVER:PORT # (This is the proxy server:port combo used by tests.)
--agent=STRING # (This designates the web browser's User Agent to use.)
--mobile # (The option to use the mobile emulator while running tests.)
--metrics=STRING # ("CSSWidth,Height,PixelRatio" for mobile emulator tests.)
--extension-zip=ZIP # (Load a Chrome Extension .zip file, comma-separated.)
--extension-dir=DIR # (Load a Chrome Extension directory, comma-separated.)
--headless # (The option to run tests headlessly. The default on Linux OS.)
--headed # (The option to run tests with a GUI on Linux OS.)
--start-page=URL # (The starting URL for the web browser when tests begin.)
--archive-logs # (Archive old log files instead of deleting them.)
--time-limit # (The option to set a time limit per test before failing it.)
--slow # (The option to slow down the automation.)
--demo # (The option to visually see test actions as they occur.)
--demo-sleep=SECONDS # (The option to wait longer after Demo Mode actions.)
--highlights=NUM # (Number of highlight animations for Demo Mode actions.)
--message-duration=SECONDS # (The time length for Messenger alerts.)
--check-js # (The option to check for JavaScript errors after page loads.)
--ad-block # (The option to block some display ads after page loads.)
--verify-delay=SECONDS # (The delay before MasterQA verification checks.)
--disable-csp # (This disables the Content Security Policy of websites.)
--enable-sync # (The option to enable "Chrome Sync".)
--reuse-session # (The option to reuse the browser session between tests.)
--maximize-window # (The option to start with the web browser maximized.)
--save-screenshot # (The option to save a screenshot after each test.)
--visual-baseline # (Set the visual baseline for Visual/Layout tests.)
--timeout-multiplier=MULTIPLIER # (Multiplies the default timeout values.)
```
(For more details, see the full list of command-line options **[here](https://github.com/seleniumbase/SeleniumBase/blob/master/seleniumbase/plugins/pytest_plugin.py)**.)
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](https://github.com/seleniumbase/SeleniumBase/blob/master/seleniumbase/config/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.
```bash
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](https://github.com/seleniumbase/SeleniumBase/blob/master/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.)
To pass additional data from the command-line to tests, add ``--data="ANY STRING"``.
Now inside your tests, you can use ``self.data`` to access that.
### **Test Directory Customization:**
For running tests outside of the SeleniumBase repo with **Pytest**, you'll want a copy of **[pytest.ini](https://github.com/seleniumbase/SeleniumBase/blob/master/pytest.ini)** on the root folder. For running tests outside of the SeleniumBase repo with **Nosetests**, you'll want a copy of **[setup.cfg](https://github.com/seleniumbase/SeleniumBase/blob/master/setup.cfg)** on the root folder. (Subfolders should include a blank ``__init__.py`` file.) These files specify default configuration details for tests. (For nosetest runs, you can also specify a .cfg file by using ``--config``. Example ``nosetests [MY_TEST].py --config=[MY_CONFIG].cfg``)
As a shortcut, you'll be able to run ``seleniumbase mkdir [DIRECTORY_NAME]`` to create a new folder that already contains necessary files and some example tests that you can run. Example:
```bash
seleniumbase mkdir ui_tests
cd ui_tests/
pytest my_first_test.py
```
### **Logging / Results from Failing Tests:**
Let's try an example of a test that fails:
```python
""" 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:
```bash
pytest test_fail.py
```
You'll notice that a logs folder, "latest_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](https://github.com/seleniumbase/SeleniumBase/blob/master/seleniumbase/config/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.
### **Creating Visual Test Suite Reports:**
(NOTE: Several command-line args are different for Pytest vs Nosetests)
#### **Pytest Reports:**
Using ``--html=report.html`` gives you a fancy report of the name specified after your test suite completes.
```bash
pytest test_suite.py --html=report.html
```
![](https://cdn2.hubspot.net/hubfs/100006/images/PytestReport.png "Example Pytest Report")
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.
```bash
pytest test_suite.py --junit-xml=report.xml
```
#### **Nosetest Reports:**
The ``--report`` option gives you a fancy report after your test suite completes.
```bash
nosetests test_suite.py --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.)
### **Using a Proxy Server:**
If you wish to use a proxy server for your browser tests (Chrome and Firefox only), you can add ``--proxy=IP_ADDRESS:PORT`` as an argument on the command-line.
```bash
pytest proxy_test.py --proxy=IP_ADDRESS:PORT
```
If the proxy server that you wish to use requires authentication, you can do the following (Chrome only):
```bash
pytest proxy_test.py --proxy=USERNAME:PASSWORD@IP_ADDRESS:PORT
```
To make things easier, you can add your frequently-used proxies to PROXY_LIST in [proxy_list.py](https://github.com/seleniumbase/SeleniumBase/blob/master/seleniumbase/config/proxy_list.py), and then use ``--proxy=KEY_FROM_PROXY_LIST`` to use the IP_ADDRESS:PORT of that key.
```bash
pytest proxy_test.py --proxy=proxy1
```
### **Changing the User-Agent:**
If you wish to change the User-Agent for your browser tests (Chrome and Firefox only), you can add ``--agent="USER AGENT STRING"`` as an argument on the command-line.
```bash
pytest user_agent_test.py --agent="Mozilla/5.0 (Nintendo 3DS; U; ; en) Version/1.7412.EU"
```
### **Building Guided Tours for Websites:**
Learn about [SeleniumBase Interactive Walkthroughs](https://github.com/seleniumbase/SeleniumBase/tree/master/examples/tour_examples/ReadMe.md) (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 setup a production environment for your testing:
* You can setup a [Jenkins](https://jenkins.io/) build server for running tests at regular intervals. For a real-world Jenkins example of headless browser automation in action, check out the [SeleniumBase Jenkins example on Azure](https://github.com/seleniumbase/SeleniumBase/blob/master/integrations/azure/jenkins/ReadMe.md) or the [SeleniumBase Jenkins example on Google Cloud](https://github.com/seleniumbase/SeleniumBase/blob/master/integrations/google_cloud/ReadMe.md).
* You can use [the Selenium Grid](https://selenium.dev/documentation/en/grid/) to scale your testing by distributing tests on several machines with parallel execution. To do this, check out the [SeleniumBase selenium_grid folder](https://github.com/seleniumbase/SeleniumBase/tree/master/seleniumbase/utilities/selenium_grid), which should have everything you need, including the [Selenium Grid ReadMe](https://github.com/seleniumbase/SeleniumBase/blob/master/seleniumbase/utilities/selenium_grid/ReadMe.md), which will help you get started.
* If you're using the [SeleniumBase MySQL feature](https://github.com/seleniumbase/SeleniumBase/blob/master/help_docs/mysql_installation.md) to save results from tests running on a server machine, you can install [MySQL Workbench](https://dev.mysql.com/downloads/tools/workbench/) to help you read & write from your DB more easily.
* If you use [Slack](https://slack.com), you can easily have your Jenkins jobs display results there by using the [Jenkins Slack Plugin](https://github.com/jenkinsci/slack-plugin). Another way to send messages from your tests to Slack is by using [Slack's Incoming Webhooks API](https://api.slack.com/incoming-webhooks).
* If you're using AWS, you can setup an [Amazon S3](https://aws.amazon.com/s3/) account for saving log files and screenshots from your tests. To activate this feature, modify [settings.py](https://github.com/seleniumbase/SeleniumBase/blob/master/seleniumbase/config/settings.py) with connection details in the S3 section, and add "``--with-s3-logging``" on the command-line when running your tests.
Here's an example of running tests with additional features enabled:
```bash
pytest [YOUR_TEST_FILE].py --with-db-reporting --with-s3-logging
```
### **Detailed Method Specifications and Examples:**
#### Navigating to a web page (and related commands)
```python
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.
```
**ProTip™:** You may need to use the get_page_source() method along with Python's find() command to parse through the source to find something that Selenium wouldn't be able to. (You may want to brush up on your Python programming skills for that.)
```python
source = self.get_page_source()
head_open_tag = source.find('
