Cucumber is a test automation framework which leverages Behavior Driven Development for collaboration in between Business and IT teams. It empowers a user to define an application’s behavior in plain English language which makes it easier for non-programmers to understand the acceptance criteria.

The core of Cucumber has been developed in Ruby programming language however it supports all the majorly used programming languages for testing such as Java, C#, Python. In this article, I will be demonstrating automation testing with Selenium, Cucumber and TestNG.

What Is Behavior Driven Development?

Behavior Driven Development is derived from Test Driven Development as a software development methodology. As a part of the Test Driven Development approach, the developer creates tests as a part of the acceptance criteria first. The developer will make sure the test is passed and will commit changes in the code. if required.

Test Driven Development is a way to ensure the system meets its requirements by ensuring a 100% test coverage. It provides an edge over other methodologies in terms of finding defects early in the cycle which reduces the cost of finding bugs and refactoring improves the code.

Cons of Test Driven Development are the maintenance of tests created, it is a test-centric methodology, non-programmers might find it hard to understand for performing selenium test automation. The test or acceptance criteria being targeted makes it hard for team collaboration. To overcome the above trouble heads, Behavior Driven Development was introduced to reduce the time to test, less code with more collaboration.
