BDD Testing Framework

Overview

Behavior-driven development, or BDD, makes it possible to write tests in a human-readable language.

PyCharm supports Gherkin -based frameworks, such as Behave.

Running a feature file

PyCharm provides the ability to run a specific feature file, or all feature files in a folder, which is specified in the corresponding run/debug configurations for Behave.

The procedure of running tests is the same as for the other testing frameworks:

1. Open the desired feature feature in the editor, or select it in the Project tool window.

2. Do one of the following:

   • Right-click the selected file or folder, and choose Run <feature file name> on the context menu of the selection.

   • Create run/debug configuration for one of the BDD frameworks, and specify the desired file of folder there.

Renaming steps

• Step definitions should not contain regular expressions

• Step names should contain alphanumeric characters only.

• A step definition should be only one in various frameworks.

• There should be a "one-to-one" mapping between a step and a step definition.

Refer to the section Renaming for details.
