The Challenges of End-to-End Testing of Microservices
Microservices work well with independent teams who have end-to-end responsibility and use an automated CI/CD pipeline. Ensuring software quality through end-to-end testing can conflict with rapidly integrating and releasing software components. If an end-to-end test fails, the CI/CD pipelines of all involved microservices are blocked until the problem causing the test to fail is solved.
