PyCharm 2017.3 Help

BDD Testing Framework

This feature is supported in the Professional edition only.

Overview

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

PyCharm supports Gherkin and the Cucumber-based frameworks:

    Find information on testing in the section Testing.

    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, or Lettuce.

    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

    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.
