What is End-to-End Testing and E2E testing Framework?

What is End-to-End (E2E) testing?

E2E testing makes sure that the application's behavior is in line with the expected requirements and that the data flow is maintained for all kinds of processes and user tasks. This type of testing approach is initiated from the end user's viewpoint and hence a real-world scenario is simulated. It verifies that all the system components can work and run accordingly under real-world scenarios.

The user experience is simulated from start to finish through the E2E testing method. Software dependencies can be found, while the system under test, its integrations and data integrity are also validated.

E2E testing frameworks:

1. Selenium: It is a suite of extensions and libraries that are being used for the purpose of building a framework through which web browser automation is enabled. Easy interaction with HTML elements is provided, which, in turn, provides flexibility for customizing the tests.

 

2. Puppeteer: Headless browser testing of Google Chrome is performed by testers using this framework. Headless Chrome is run in Node.js to perform a majority of tasks such as locating elements, network traffic, handling requests and responses etc.

 

3. Nightwatch.js: It is an open-source, browser-based automation framework that is built on the platform of Node.js. End-to-end testing of web applications is automated by a simple yet powerful syntax provided by it. It supports various web drivers and frameworks like FirefoxDriver, ChromeDriver and Selenium.

 

4. QA Wolf: It is a cloud-based E2E testing framework. This tool is considered to be highly resourceful for those organizations who want to relieve their QA teams from test maintenance. There is no specific setup required to use this framework. Failures are reproduced faster with recorded videos, logs and highlighted lines of code leading to failure. The tests can be fixed and maintained directly in the browser.

 

5. Cypress: It is a front-end test automation tool through which the front-end UI of the web apps are debugged. Waits and time issues that are present in Selenium are solved by the cypress tool and the underlying framework is Mocha.
