In end-to-end testing, the application is tested rigorously after every iteration and sprint. Thus, there are lesser chances of failure and risks in the future.

In end-to-end testing, the application is tested and validated at all the layers – data layer, business layer, integration layer and presentation layer. This helps ensure complete correctness and health of the application.

As the application is tested thoroughly, there is no looking back. End-to-end testing reduces the chances of frequent breakdowns and ultimately reduces the repetitive testing efforts.

End-to-end testing also increases the confidence in the functioning and performance of the application before its release as the application is tested across different endpoints for different devices and platforms comprehensively.

End-to-end testing via automation testing tool reduces errors recurrence, which means the application doesn’t require undergoing repeated testing. This considerably reduces the testing costs and time and helps achieve better productivity in other significant processes.

End-to-end testing is a must to test and scale the application across a range of different systems, devices, layers, servers, database interactions, APIs and communication. Further, automating end-to-end testing allows you to quickly respond to changing business needs and adds greater agility to the entire testing project.
