In order to get better advantage of the software testing, organizations are nowadays taking a step forward. They implement important acceptance test scenarios while development is in-progress. This approach is commonly known as Behavior Driven Development (BDD).
Cucumber is a software tool is used for testing other software. It runs automated acceptance tests written in a behavior-driven development (BDD) style. Cucumber’s executable specifications encourage closer collaboration, helping teams keep the business goal in mind at all times.
Central to the Cucumber BDD approach is, its plain language parser called Gherkin. It allows expected software behaviors to be specified in a logical language that customers can understand. As such, Cucumber allows the execution of feature documentation written in business-facing text (Business requirements).
Gherkin is the language that Cucumber uses to define test cases. It is designed to be non-technical and human readable, and collectively describes use cases relating to a software system
First, the developers, testers and business folks explore the problem domain, and collaborate to produce concrete examples that describe the behavior they want.
Next, the team uses Cucumber to run those examples as automated acceptance tests.
As the team works on the solution, Cucumber tells you which examples are implemented and working, and warns you about the ones that aren’t.
Advantages of Cucumber over Other Tools:
- Cucumber supports different languages like Java.net and Ruby.
- It acts as a bridge between the business and technical language. We can accomplish this by creating a test case in plain English text.
- It allows the test script to be written without knowledge of any code, it allows the involvement of non-programmers as well.
- It serves the purpose of end-to-end test framework, unlike other tools.
- Due to simple test script architecture, Cucumber provides code reusability.
