Other features include clear reports, detailed logs, tabular syntax, and test cases that are driven by data. 

7. Soap UI

The test Automation tool Soap UI accelerates the API tests through its “point and click” and “drag and drop” facilities and capabilities. The standard interface tool helps developers run the tests from all task schedulers, and the tests can also be integrated within the build process. There is support for SOAP and REST services, and both open-source and pro (paid) versions are available. Some of the features of the tool are:

• Reusability of scripts

• Asynchronous and data=driven testing

• Creation of mock services

8. HPE Unified Functional Testing (UFT)

The tool is one of the best automation tools for developers who wish to perform testing on multiple tasks. It also works swiftly in different development environments and on different browsers. UFT tool can test all apps, including those built for Windows, IOS, and Android. It integrates with Jenkins and the other capable app development tools. The API testing tools help in the evaluation of load performance and functionally of APIs of the app that is being tested.
