behave¶

behave implements behaviour-driven development (BDD). BDD is an agile software development technique that promotes collaboration between development, quality assurance and non-technical or business staff on a software project. The term was originally coined in 2003 by Daniel Terhorst-North in response to test-driven development and encompasses acceptance testing or customer-test-driven development practices as found in extreme programming. In Selling BDD to the Business, he gave the following definition:

‚BDD is a second-generation, outside–in, pull-based, multiple-stakeholder, multiple-scale, high-automation, agile methodology. It describes a cycle of interactions with well-defined outputs, resulting in the delivery of working, tested software that matters.‘

Gherkin¶

Description language based on natural written language for the textual specification of software requirements. Only certain keywords are predefined.

Scenario: Add an item to the database
  Given an empty database
   When an item with a summary is added
   Then the number of items should be 1
    and the queried item from the db should correspond to the added object.

Each scenario is an example intended to illustrate a specific aspect of the application’s behaviour.

Installation¶

You can install behave in your virtual environments with:

Linux/macOS
