tau-pytest-bdd

This repository contains example code for the Behavior-Driven Python with pytest-bdd course from Test Automation University. There is a branch for each chapter of the course showing the state of the code at the completion of the chapter.

Version 4 Warning

The TAU course was developed with pytest-bdd version 3. Unfortunately, the version 4 update has incompatible changes. @given methods must now include a target_fixture parameter in order to work like pytest fixtures. The TAU videos and transcripts use the old style of code, but the example code here now uses the new style of code. Below is an example of the new style of code needed:

@given("the basket has 2 cucumbers", target_fixture='basket')
def basket():
    return CucumberBasket(initial_count=2)

Setup

This project requires an up-to-date version of Python 3. It also uses pipenv to manage packages.

To set up this project on your local machine:

1. Clone it from this GitHub repository.
2. Run pipenv install from the command line in the project's root directory.
3. For Web UI tests, install the appropriate browser and WebDriver executable.
   • These tests use Firefox and geckodriver.

Running Tests

Run tests simply using the pytest command. Depending upon your environment, it may be better to use python -m pytest. If you are using pipenv, then run pipenv run python -m pytest. Use the "-k" option to filter tests by tags.
