What is E2E Tests?
The abbreviation E2E stands for End to End. E2E tests mean tests that automatically perform common actions through the frontend in a very realistic environment to check that all data from the backend is sent correctly and displayed correctly in the frontend went. Thus, the entire app is tested from one end (front end) to the other end (back end).
E2E or End-to-end testing is a method that evaluates the work sequence of a complex product in a start-to-finish process. End-to-end testing verifies that all components of the system are capable of running and performing optimally under real-world scenarios. In this testing the entire software product from start to finish to ensure that the application flow behaves as expected. It defines the system dependencies of the product and ensures that all integrated pieces work together as expected.
The main objective of end-to-end (E2E) testing is to test from the end user experience by simulating a real user scenario and validating the system under test and its components for integration and data integrity.
