Difference between Cucumber Testing and Selenium Testing

Cucumber Testing: Cucumber testing is a software testing which uses the tool that supports Behavior Driven Development (BDD). It offers a way to write tests that anybody can understand regardless of their technical knowledge. Selenium Testing: Selenium testing is a software testing that uses a tool that supports Functional and Performance (Selenium Grid) testing tool. It is quite similar to cucumber testing despite of some changes.

Difference between Cucumber Testing and Selenium Testing:

Cucumber Testing	Selenium Testing
It uses a behavior-driven development tool.	It uses functional and performance (selenium grid) tool.
Plugin in cucumber works faster.	Plugins are slower than cucumber.
Cucumber Framework supports other language as well beyond Ruby like Java, Scala, Groovy etc.	Selenium supports Java, C#, Python, Ruby, Kotlin, Java Script many other languages.
Writing automation steps are joint effort of testers and developer.	Like Cucumber Tool, writing automation steps are joint effort of testers and developer.
Cucumber can support web environment, database testing, ETL testing in collaboration with any programming languages.	Supports only web environment.
It is open source.	It is also open source.

Conclusion: Actually Cucumber is a tool that supports the BDD (Behavior Driven Development) approach. BDD approach is very popular today as the scenarios in feature file are written in plan English, hence whether it’s Business Analyst, Developer, Tester or any other project stake holder, anyone can understand. Whereas Selenium provides the libraries available to us to interact with various web browsers. Cucumber has to attach to test framework like Junit, TestNG etc. to be functioning and Selenium is also needed within these frameworks to automate web. So, we should say Cucumber and Selenium work together to build a framework. We can use Cucumber for any other type of testing such as ETL Testing, Database Validation etc. in collaboration with programming languages like Java, Scala, Groovy etc. but Selenium is only used for web automation.
