Splinter plugin for pytest testing framework
Splinter plugin for the pytest runner
pip install pytest-splinter
- 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).
- 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.
- 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:
@pytest.fixture 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.""" browser.visit('http://google.com') admin_browser.visit('http://admin.example.com')
- Implicit wait timeout to be passed to Selenium webdriver. Fixture gets the value from the command-line option splinter-implicit-wait (see below)
- Explicit wait timeout (for waiting for expicit condition via wait_for_condition). Fixture gets the value from the command-line option splinter-wait-time (see below)
- 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)
- 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’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 conftest.py file:
import pytest @pytest.fixture(scope='session') def splinter_webdriver(): """Override splinter webdriver name.""" return 'phantomjs'
- 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’.
- 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)
- 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.
- Comma-separated list of content types to automatically download. By default it’s the all known system mime types (via mimetypes standard library).
- Browser load condition, python function which should return True. If function returns False, it will be run several times, until timeout below reached.
- Browser load condition timeout in seconds, after this timeout the exception WaitUntilTimeout will be raised.
- Browser explicit wait timeout in seconds, after this timeout the exception WaitUntilTimeout will be raised.
- Firefox profile preferences, a dictionary which is passed to selenium webdriver’s profile_preferences
- 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
- Webdriver keyword arguments, a dictionary which is passed to selenium webdriver’s constructor (after applying firefox preferences)
- Size of the browser window on browser initialization. Tuple in form (<width>, <height>). Default is (1366, 768)
- pytest-splinter browser screenshot directory. This fixture gets the value from the command-line option splinter-screenshot-dir (see below).
- 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).
- Encoding of the html screenshot on test failure. UTF-8 by default.
- Function to get browser html screenshot. By default, it saves browser.html with given path and splinter_screenshot_encoding encoding.
- Function to get browser image (png) screenshot. By default, it calls browser.save_sceenshot with given path.
- Filesystem path of the webdriver executable. This fixture gets the value from the command-line option splinter-webdriver-executable (see below).
- Class to use for browser instance. Defaults to pytest_splinter.plugin.Browser.
- 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 https://facebook.com). 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.
- Run Chrome in headless mode. As the writing of this (2017-07), available only in unreleased Splinter master version. Defaults to false.
Selenium webdriver implicit wait. Seconds (default: 5).
selenium webdriver speed (from command to command). Seconds (default: 0).
Selenium webdriver socket timeout for for communication between the webdriver and the browser. Seconds (default: 120).
Webdriver name to use. (default: firefox). Options:
For more details refer to the documentation for splinter and selenium.
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.
pytest-splinter should use a single browser instance per test session. Choices are ‘true’ or ‘false’ (default: ‘true’).
pytest-splinter should take browser screenshots on test failure. Choices are ‘true’ or ‘false’ (default: ‘true’).
pytest-splinter browser screenshot directory. Defaults to the current directory.
Filesystem path of the webdriver executable. Used by phantomjs and chrome drivers. Defaults to the None in which case the shell PATH variable setting determines the location of the executable.
As mentioned above, browser is a fixture made by creating splinter’s Browser object, but with some overrides.
- Added possibility to wait for condition on each browser visit by having a fixture.
Several browsers for your test
You can have several browsers in one test.
import pytest @pytest.fixture def admin_browser(browser_instance_getter): return browser_instance_getter(admin_browser) def test_with_several_browsers(browser, admin_browser): browser.visit('http://example.com') admin_browser.visit('about:blank') assert browser.url == 'http://example.com'
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 continuos 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 slave 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 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 = "http://www.google.com" browser.visit(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 button.click() assert browser.is_text_present('splinter.cobrateam.info'), 'splinter.cobrateam.info wasn't found...
