Install pytest-splinter

pip install pytest-splinter


The plugin provides a set of fixtures to use splinter for browser testing with pytest


  • browser

    Get the splinter’s Browser. Fixture is underneath session scoped, so browser process is started once per test session, but the state of the browser will be clean (current page is blank, cookies clean).

  • session_browser

    The same as browser except the lifetime. This fixture is session-scoped so will only be finalized at the end of the whole test session. Useful if you want to speedup your test suite paying with reduced test isolation.

  • browser_instance_getter

    Function to create an instance of the browser. This fixture is required only if you need to have multiple instances of the Browser in a single test at the same time. Example of usage:

def admin_browser(request, browser_instance_getter):
    """Admin browser fixture."""
    # browser_instance_getter function receives parent fixture -- our admin_browser
    return browser_instance_getter(request, admin_browser)

def test_2_browsers(browser, admin_browser):
    """Test using 2 browsers at the same time."""
  • splinter_selenium_implicit_wait

    Implicit wait timeout to be passed to Selenium webdriver. Fixture gets the value from the command-line option splinter-implicit-wait (see below)

  • splinter_wait_time

    Explicit wait timeout (for waiting for explicit condition via wait_for_condition). Fixture gets the value from the command-line option splinter-wait-time (see below)

  • splinter_selenium_speed

    Speed for Selenium, if not 0 then it will sleep between each selenium command. Useful for debugging/demonstration. Fixture gets the value from the command-line option splinter-speed (see below)

  • splinter_selenium_socket_timeout

    Socket timeout for communication between the webdriver and the browser. Fixture gets the value from the command-line option splinter-socket-timeout (see below)

  • splinter_webdriver

    Splinter’s webdriver name to use. Fixture gets the value from the command-line option splinter-webdriver (see below). To make pytest-splinter always use certain webdriver, override a fixture in your file:

import pytest

def splinter_webdriver():
    """Override splinter webdriver name."""
    return 'chrome'
  • splinter_remote_url

    Splinter’s webdriver remote url to use (optional). Fixture gets the value from the command-line option splinter-remote-url (see below). Will be used only if selected webdriver name is ‘remote’.

  • splinter_session_scoped_browser

    pytest-splinter should use single browser instance per test session. Fixture gets the value from the command-line option splinter-session-scoped-browser (see below)

  • splinter_file_download_dir

    Directory, to which browser will automatically download the files it will experience during browsing. For example when you click on some download link. By default it’s a temporary directory. Automatic downloading of files is only supported for firefox driver at the moment.

  • splinter_download_file_types

    Comma-separated list of content types to automatically download. By default it’s the all known system mime types (via mimetypes standard library).

  • splinter_browser_load_condition

    Browser load condition, python function which should return True. If function returns False, it will be run several times, until timeout below reached.

  • splinter_browser_load_timeout

    Browser load condition timeout in seconds, after this timeout the exception WaitUntilTimeout will be raised.

  • splinter_wait_time

    Browser explicit wait timeout in seconds, after this timeout the exception WaitUntilTimeout will be raised.

  • splinter_firefox_profile_preferences

    Firefox profile preferences, a dictionary which is passed to selenium webdriver’s profile_preferences

  • splinter_firefox_profile_directory

    Firefox profile directory to use as template for firefox profile created by selenium. By default, it’s an empty directly inside pytest_splinter/profiles/firefox

  • splinter_driver_kwargs

    Webdriver keyword arguments, a dictionary which is passed to selenium webdriver’s constructor (after applying firefox preferences)

import pytest
from pathlib import Path

def splinter_driver_kwargs():
    Webdriver kwargs for Firefox.
    return {"service_log_path": Path("/log/directory/geckodriver.log")}

The snippet below configures Chrome to ignore certificate errors and sets a specific window size

import pytest
from selenium import webdriver

def splinter_driver_kwargs():
    """Override Chrome WebDriver options"""
    chrome_options = webdriver.ChromeOptions()

    # List of Chromium Command Line Switches

    return {"options": chrome_options}
  • splinter_window_size

    Size of the browser window on browser initialization. Tuple in form (<width>, <height>). Default is (1366, 768)

  • splinter_screenshot_dir

    pytest-splinter browser screenshot directory. This fixture gets the value from the command-line option splinter-screenshot-dir (see below).

  • splinter_make_screenshot_on_failure

    Should pytest-splinter take browser screenshots on test failure? This fixture gets the value from the command-line option splinter-make-screenshot-on-failure (see below).

  • splinter_screenshot_encoding

    Encoding of the html screenshot on test failure. UTF-8 by default.

  • splinter_screenshot_getter_html

    Function to get browser html screenshot. By default, it saves browser.html with given path and splinter_screenshot_encoding encoding.

  • splinter_screenshot_getter_png

    Function to get browser image (png) screenshot. By default, it calls browser.save_sceenshot with given path.

  • splinter_driver_executable

    Filesystem path of the webdriver executable. This fixture gets the value from the command-line option splinter-webdriver-executable (see below).

  • splinter_browser_class

    Class to use for browser instance. Defaults to pytest_splinter.plugin.Browser.

  • splinter_clean_cookies_urls

    List of additional urls to clean cookies on. By default, during the preparation of the browser for the test, pytest-splinter only cleans cookies for the last visited url from previous test, as it’s not possible to clean all cookies from all domains at once via webdriver protocol, by design. This limitation can be worked around if you know the list of urls, the domains for which you need to clean cookies (for example If so, you can override this fixture and put those urls there, and pytest-splinter will visit each of them and will clean the cookies for each domain.

  • splinter_headless

    Run Chrome in headless mode. Defaults to false.

Command-line options

  • –splinter-implicit-wait

    Selenium webdriver implicit wait. Seconds (default: 5).

  • –splinter-speed

    selenium webdriver speed (from command to command). Seconds (default: 0).

  • –splinter-socket-timeout

    Selenium webdriver socket timeout for for communication between the webdriver and the browser. Seconds (default: 120).

  • –splinter-webdriver

    Webdriver name to use. (default: firefox). Options:

    • firefox

    • remote

    • chrome

    For more details refer to the documentation for splinter and selenium.

  • –splinter-remote-url

    Webdriver remote url to use. (default: None). Will be used only if selected webdriver name is ‘remote’.

    For more details refer to the documentation for splinter and selenium.

  • –splinter-session-scoped-browser

    pytest-splinter should use a single browser instance per test session. Choices are ‘true’ or ‘false’ (default: ‘true’).

  • –splinter-make-screenshot-on-failure

    pytest-splinter should take browser screenshots on test failure. Choices are ‘true’ or ‘false’ (default: ‘true’).

  • –splinter-screenshot-dir

    pytest-splinter browser screenshot directory. Defaults to the current directory.

  • –splinter-webdriver-executable

    Filesystem path of the webdriver executable. Used by chrome driver. Defaults to the None in which case the shell PATH variable setting determines the location of the executable.

  • –splinter-headless

    Override splinter_headless fixture. Choices are ‘true’ or ‘false’, default: ‘true’.

Browser fixture

As mentioned above, browser is a fixture made by creating splinter’s Browser object, but with some overrides.

  • visit

    Added possibility to wait for condition on each browser visit by having a fixture.

  • wait_for_condition

    Method copying selenium’s wait_for_condition, with difference that condition is in python, so there you can do whatever you want, and not only execute javascript via browser.evaluate_script.

Automatic screenshots on test failure

When your functional test fails, it’s important to know the reason. This becomes hard when tests are being run on the continuous integration server, where you cannot debug (using –pdb). To simplify things, a special behaviour of the browser fixture is available, which takes a screenshot on test failure and puts it in a folder with the a naming convention compatible to the jenkins plugin. The html content of the browser page is also stored, this can be useful for debugging the html source.

Creating screenshots is fully compatible with pytest-xdist plugin and will transfer the screenshots from the worker nodes through the communication channel automatically.

If a test (using the browser fixture) fails, you should get a screenshot files in the following path:


The splinter-screenshot-dir for storing the screenshot is generated by a fixture and can be provided through a command line argument, as described above at the configuration options section.

Taking screenshots on test failure is enabled by default. It can be controlled through the splinter_make_screenshot_on_failure fixture, where return False skips it. You can also disable it via a command line argument:

pytest tests/functional --splinter-make-screenshot-on-failure=false

In case taking a screenshot fails, a pytest warning will be issued, which can be viewed using the -rw argument for pytest.

Python3 support

Python3 is supported, check if you have recent version of splinter as it was added recently.


def test_some_browser_stuff(browser):
    """Test using real browser."""
    url = ""
    browser.fill('q', 'splinter - python acceptance testing for web applications')
    # Find and click the 'search' button
    button = browser.find_by_name('btnK')
    # Interact with elements
    assert browser.is_text_present(''), " wasn't found... We need to"
