BDD with cucumber and gherkins using MindMap

 Business-Driven Development is a collaborative approach that focuses on aligning software development with business goals through the creation of executable specifications

Business driven development

Translating Business-Driven Development to executable specification in gherkins

Keywords and code blocks in Gherkins specification

  • Feature is to provide a high-level description of a software feature.
  • Rule is to represent one business rule that should be implemented
  • Scenario or Example is a concrete example that illustrates a business rule
  • Scenario Outline is used to run the same Scenario multiple times, with different set of data.


  • Steps are used to define scenarios. steps can be:
    • Given - describe the precondition of the system
    • When - describes an event, or an action
    • Then - describe an expected outcome, or result
    • But - describe an outcome that is not expected
  • There can be multiple steps of same type in a scenario.
  • Background define a set of steps that are common to all scenarios in a feature file. Execution is after each scenarios
  • Hooks are blocks of code that run before or after certain events. they are defined by annotation "@Before" and "@After" annotations. these are setup() and teardown() code in the application.

Understanding components of a cucumber framework

Components of a cucumber framework

Feature File:

  • File corresponding to a feature/rule
  • Can have multiple scenarios/examples, scenario outline and background.
  • Annotations can be used to group tests, e.g: smoke, nightly, regression

Step definition File

  • For given, when then, but steps defined in feature file, the logical code is written in a step definition file.
  • Annotation @Given, @then are used to match the step definition method with the one provided in feature file


TestRunner File to execute tests

  • TestRunner file defines the tests to be executed,

Components of a Test Runner File:

  • Annotations: uses annotations from testing frameworks like JUnit or TestNG to define its purpose and behavior.
  • Glue: specifies the package where Cucumber can find the step definitions
  • Features: feature files which needs to be executed
  • Plugins: defines the reporting path, tags and formatting.
