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.
How Cucumber Works
Cucumber is a tool that supports Behavior Driven Development (BDD). Hence, it offers a way to write tests that anybody can understand, regardless of their technical knowledge. Behavior Driven Development (BDD) is a rising methodology to test and likewise to check your code. In BDD, users write scenarios or acceptance tests that describe the behavior of the system from the customer’s perspective, for review and sign-off by the product owners before developers write their codes. Cucumber use Ruby programming language.
The customer can describe their requirements as a series of examples called scenarios, in plain text files using the Gherkin language in the Given When Then format. In Cucumber world, these files are called feature files. These files are reviewed by the Scrum team to get a clear understanding of the requirements. Hence, before starting the actual development.
Once development is underway, the developers and also the QA will write Step Definitions. These step definitions are essential snippets of code which bind the scenarios from the feature files to the test code which execute actions against the application under test.
- It is helpful to involve business stakeholders, especially those who cannot easily read code.
- Cucumber Testing focuses on the end-user experience.
- Style of writing tests allow for easier reuse of code in the tests
- This software testing tool allows for a quick and easy setup and also execution.
- Cucumber is an efficient tool for testing.
- Testers can write Test scripts without having in-depth knowledge of programming
- Plugins are faster as compared to Selenium
- Supports various programming languages
- Code is re-usable
- Cucumber is simple and can also be setup quickly
- Flexible with different software platforms like Selenium, Ruby on Rails, Watir, Spring framework, and so forth
- May be integrated with BrowserStack, qTEst Management, Ghostlab, Karate DSL, Howitzer, Experitest, and CrossBrowser Testing
Features of Cucumber
- It is a behavior-driven development tool
- Another important feature of this testing tool is it is free
- Plugin in Cucumber works faster
- Cucumber Framework supports other languages as well beyond Ruby like Java, Scala, Groovy etc.
Cucumber is an excellent tool in checking the behavior of a feature at the API layer with integration tests where each function can be thoroughly tested. Furthermore, this testing tool allows plain language clarity across the software testing teams. Thus, it will enable requirements to be questioned with a logical business flow. That shows everyone what to expect from a high or low level. Which in turn allows a complete understanding of how to thoroughly test the component.
Furthermore, the tool works beautifully with a simplistic and naive view of tests and scenarios, such as everyone’s favorite login functionality. Moreover, Cucumber’s open-source and also commercial collaboration tools combine with world-class training and consulting. Therefore taking your engineering teams’ performance to another level. Hence, thousands of teams worldwide trust this software testing tool to deliver better products, faster.
