An Update
Hello again! I’ve decided I want to post about Cucumber!
What is Cucumber Anyway?
Cucumber is a software acceptance testing tool (originally written in Ruby) that helps automate tests, and foster collaborative communication amongst developers, business stakeholders, and anyone involved in the Software Development Life Cycle. Cucumber inherently enforces good Behavior-Driven Development, and employs simple syntax and structure for writing tests.
Context and Concepts:
The following quotes were taken from the book I discussed in my previous post, chapter 1, page 8.
- “Software teams work best when the developers and business stakeholders are communicating clearly with one another. A great way to do that is to collaboratively specify the work that’s about to be done using automated acceptance tests.”
- “When the acceptance tests are written as examples, they stimulate people’s imaginations and help them to see other scenarios they hadn’t previously considered.”
- “When the team members write their acceptance tests collaboratively [together, concurrently in a room somewhere, ideally], they can develop their own ubiquitous language for talking about their problem domain.”
- “Cucumber was designed specifically to help business stakeholders get involved in writing acceptance tests.”
- “Each test case in Cucumber is called a scenario, and scenarios are grouped into features.” Each scenario contains several steps.”
- “The business-facing parts of a Cucumber test suite, stored in feature [.feature] files, must be written according to syntax rules–known as Gherkin–so that Cucumber can read them.”
- FYI: Gherkin is written using a Given-When-Then syntax. Given an initial system context, when an event occurs, then we expect … to occur.
- “Under the hood, step definitions translate from the business-facing language of steps into code.”
