PyTest Automated Testing

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

For Windows

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

Set up your first Python test with PyTest

First, make sure you have installed pytest-selenium:

pip install pytest-selenium

You are now ready to start testing with our Selenium grid.
We have a working example on GitHub as well: PyTest Selenium Example.

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


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

To see how to do this, please select a combination of browser, version and platform in the drop-down menus below:

1. Select a Platform
2. Select a Browser

Testing Internal/Staged 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

Other Options

We offer many other test options, for example: disable video recording, specifying a custom Firefox Profile, loading Chrome/Firefox/Safari extensions, running an executable before your test starts, uploading files, ...
See our list of test options for a full list of options to customize your tests.

Parallel Testing

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 concurrent VMs (how many tests you can run in parallel).
For example: if you have a plan with 5 concurrent VMs, it is possible to start more tests. TestingBot will queue the additional tests and run the tests as soon as slots become available.

Pick a Python Test Framework

  • Behave

    Behave is behaviour-driven development Python style.

  • Lettuce

    Lettuce is a Python BDD plugin based on Ruby's Cucumber, offering Gherkin stories.

  • PyUnit

    PyUnit is the standard unit testing framework module for Python, described as a Python version of JUnit.
