Cucumber and Selenium are two widely used testing frameworks and technologies. Selenium is widely used for functional testing in many organizations. These companies use Cucumber in conjunction with Selenium because Cucumber makes the application flow easier to read and comprehend. The most important advantage of combining Cucumber and Selenium is that it allows developers to build test cases in simple feature files that managers, non-technical stakeholders, and business analysts can understand. It allows you to develop tests in Gherkin, a human-readable programming language. Java,.NET, PHP, Python, Perl, and other programming languages are supported by the Selenium-Cucumber framework.
