Decoupling the client and server is a current trend in designing both Web and mobile applications.
API and services are reused in more than one application or component. These changes, in turn, require the teams to test API and services independent from the application using them.
When API and services are used across client applications and components, testing them is more effective and efficient than testing the client. The trend is that the need for API and services test automation continues to increase, possibly outpacing that of the functionality used by the end-users on user interfaces.
Having the right process, tool and solution for API automation test are more critical than ever. Therefore, it is worth your effort in learning the best API Testing Tools for your testing projects.
