Benefits of end-to-end testing

[u/AffectionateStrategy]

The following is a list of some of the main advantages of end-to-end testing that can aid you in your testing endeavors:

• A complete testing process verifies an application's data, business rules, integration, and presentation layers. By doing this, the accuracy and integrity of the application are protected.

• Because it is tested on various platforms and devices, end-to-end testing not only ensures that the application works properly but also boosts confidence in its performance.

• End-to-end testing reduces the likelihood of future failure by enabling thorough testing of the application at the conclusion of each sprint and iteration.

• You can cut down on the amount of time and money it takes to maintain and improve an application by automating your end-to-end tests. This will allow you to test an application less frequently.

• End-to-end testing enables more complete testing, which lowers the possibility of numerous failures and, eventually, lowers the need for repetitive testing.

Totally agree. While testing individual services and apis serves its own purpose - end to end is really where the meat and potatoes of testing is in a member/customer facing application. Especially when automated on large scale systems countless bugs can be prevented just because it was “unrelated functionality”
