BDD Testing Framework
Behavior-driven development, or BDD, makes it possible to write tests in a human-readable language.
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:
Open the desired feature feature in the editor, or select it in the Project tool window.
Do one of the following:
Right-click the selected file or folder, and chooseon the context menu of the selection.
Create run/debug configuration for one of the BDD frameworks, and specify the desired file of folder there.
When renaming Gherkin steps, mind the following limitations:
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.
