API testing (Application Programming Interface Testing) is a software testing Testing TypeWhich focuses on the determination if the developed APIs meet the expectations regarding the functionality, reliability, performance, and security of the application.

The interest in API testing has been growing steadily over the last couple years, depending onGoogle Trends. Research by Smartbear over 5,000 software professionals in 2017 showed the number of API testers automating more than 50% of their tests expected the numbers to grow by 30 % (from 59% to 77%) in the next two years and 80% of the survey participants reported they were responsible for testing APIs.Couple

The the right process, tool and solution for API automation test are more critical than ever. And with the shift-left trend, API testing is more than just a quality control solution but a component component of a success CI/CD deployment.

This article will provide the summary of the Top API Testing Tools cover both open-source and commercial solutions that testing teams can select to suit their needs.

  • Quickly create custom code using Groovy
  • Powerful data-driven testing: Data loaded from files, and databases, and Excel so that they can simulate how consumers interact with the APIs
  • Create complex-scenarios & support asynchronous testing
  • Reusability of Scripts: load tests and security scans can be reused for functional test cases in a just several steps

Pricing: Free - $659/year

2. Postman

Being originally a Chrome browser plugin, Postman now extends their solution with the native version for both Mac and Windows.
