Feature files

We are using the Gherkin language to describe the features.

To get started, create a features directory in the test directory and write your feature files (.feature files) in the features directory.

The difference with normal BDD usage is in the sense of the keywords:

• Given is used to set up the game.

• When return a Behavior object that will be used to test the game.

• Then is used to make assertions after the agent’s play.

Here is an example of a feature file:

Feature: Flappy Bird Game

    @easy
    Scenario Outline: Testing the pipe size easy
        Given first pipe at <i> and second pipe at <j>
        When bird flies
        Then bird should have passed <k> pipes

        Examples:
            | i   | j   | k |
            | 0   | 0   | 2 |
            | 0.5 | 0.5 | 2 |
            | 1   | 1   | 2 |

Note

You can check in the documentation of the Gherkin language or in the behave documentation for more information.
