End-To-End testing of a microservice application ensures that every process in the form is running properly. This validates that the system as a whole is working properly. As the microservices application is built with multiple modules orchestrated dynamically, an end to end testing covers all the gaps between the services.
The steps to an end-to-end microservices testing are:
Define what you expect from an e2e testing.
Define the scope of the system to be tested.
Perform authentication in a test environment.
Choose a testing framework that addresses most of the issues.
Test Asynchronous flows
