Cypress is the future tool for testing front end modern web applications. It aims to overcome the hurdles that the engineers and developers face while testing web applications based on React and AngularJS. It is a quick, effortless and dependable tool for testing any applications that run on browsers.
Cypress is commonly compared with Selenium. But there are a lot of differences between Cypress and Selenium in terms of architecture and foundation. Cypress is targeted for the purposes listed below −
Thus Cypress is used to test a wide range of applications that are operational in a browser. Cypress is free and we need not buy a license for its use. It allows us to create our test cases while our application is being developed. So it can be used best in a Test Driven Development framework. Cypress also has the Dashboard service which helps to record our test execution.
Cypress can be used for all sorts of development activities as it gives a platform where debugging is fast and code maintainability is easy.
Important features of Cypress −
Cypress gives the functionality of capturing snapshots during execution. The hover over commands present in the Command Log describes each event in a test step.
Cypress gives easy debugging from the Developer Tools. The errors and stack trace make debug fast and painless.
Cypress ensures that we need not add synchronization techniques like sleep and wait in our test cases. It waits by default for the next actions or verifications before moving to the next step.
Cypress checks the characteristics of the functions, timers and responses to the server. This is critical from a unit testing point of view.
Cypress has the capability to test the edge test cases by mocking the server time response.
Cypress has the capability to capture screenshots on failure by default. It can also take the videos of the entire test suite execution while running from the command line interface.
Cypress allows cross browser testing. It supports browsers like Firefox (still under construction), Chrome (Electron and Edge).
Cypress can integrate with Continuous Integration tools for triggering the execution in multiple parameters.
Cypress, due its architectural design, gives a quick, steady and dependable test execution results in comparison to other tools in automation.
Cypress verifies the responsiveness of a web page with the help of viewport sizing.
Cypress has the test status menu which displays the count of the number of test cases that are passed or failed.
Cypress by default reloads all the updates made in the tests.
Cypress has a very good documentation which gives necessary support for creating our end to end test cases.
Cypress has a proper error logging message which describes the reason for our script failure.
Cypress has a simple and pleasing API and it does not need any configuration to start with.
