PyTest Automated Testing

See our PyTest Selenium Example for a simple example on how to run PyTest tests on TestingBot.

Let's start with making sure Python is available on your system.

For Windows: For Linux/macOS:
  • Run python --version to see which Python version is currently installed, make sure it is 2.5.X or above.
  • macOS, Ubuntu and most other Linux distros come with Python pre-installed.


First, make sure you have installed pytest-selenium:

pip install pytest-selenium

You are now ready to start testing with our Selenium grid.

Setup credentials

To authenticate with our Selenium grid, you'll need to configure PyTest to pass your credentials.
You can either do this via environment variables, or by using a config file.

  • Environment variables:
    export TESTINGBOT_KEY=key
    export TESTINGBOT_SECRET=secret
  • Config file:

    Create a ~/.testingbot file with this content:

    key = key
    secret = secret

Example code

Save the example in a file called test_sample.py. (Important: the filename should start with test_)

import pytest

class TestSample:

    def test_sample(self, driver):
        title = "Google"
        assert title == driver.title

To run this test, run this command:

pytest --driver TestingBot --capability browserName chrome --capability version latest --capability platform WIN10

This will run the test on the latest version of Chrome on Windows 10. To run on different platforms, please see the configuration option below.

PyTest Selenium provides built-in support for TestingBot. See the PyTest + TestingBot documentation.

Configuring capabilities

To run your existing tests on TestingBot, your tests will need to be configured to use the TestingBot remote machines. If the test was running on your local machine or network, you can simply change your existing test like this:

pytest test_sample.py
pytest --driver TestingBot --capability browserName chrome --capability version latest --capability platform WIN10

Specify Browsers & Devices

To let TestingBot know on which browser/platform/device you want to run your test on, you need to specify the browsername, version, OS and other optional options in the capabilities field.

Testing Internal Websites

We've built TestingBot Tunnel, to provide you with a secure way to run tests against your staged/internal webapps.
Please see our TestingBot Tunnel documentation for more information about this easy to use tunneling solution.

The example below shows how to easily run a PyTest WebDriver test with our Tunnel:

1. Download our tunnel and start the tunnel:

java -jar testingbot-tunnel.jar key secret -i pyTunnel

2. Run your test and specify the tunnelIdentifier which we've added in the step above (-i pyTunnel)

pytest --driver TestingBot --capability browserName chrome --capability version latest --capability platform WIN10 --capability tunnelIdentifier pyTunnel

Run tests in Parallel

Parallel Testing means running the same test, or multiple tests, simultaneously. This greatly reduces your total testing time.

You can run the same tests on all different browser configurations or run different tests all on the same browser configuration.
TestingBot has a large grid of machines and browsers, which means you can use our service to do efficient parallel testing. It is one of the key features we provide to greatly cut down on your total testing time.

You can use PyTest's -n option to run multiple tests at the same time or use PyTest Parallel (recommended way).


Every plan we provide comes with a limit of parallel tests.
If you exceed the number of parallel tests assigned to your account, TestingBot will queue the additional tests (for up to 6 minutes) and run the tests as soon as slots become available.

Mark tests as passed/failed

As TestingBot has no way to dermine whether your test passed or failed (it is determined by your business logic), we offer a way to send the test status back to TestingBot. This is useful if you want to see if a test succeeded or failed from the TestingBot member area.

You can use our Python API client to report back test results.

tb = testingbotclient.TestingBotClient(key, secret)
tb.tests.update_test(self.driver.session_id, status_message=.., passed=1|0, build=.., name=..)
