RECIPE 31 – Performance Testing of APIs

To create a reliable API, the performance of an API should be tested. Though the User interface of an API may be outstanding, it is the performance of the API that matters the most. The process to test the performance of an API includes load testing i.e. the memory bottleneck and data limitations.


Memory bottlenecks occur when the server is not able to handle multiple requests at a time and data limitations occur when the request posts different data from what the API expects.

This recipe focuses on how to successfully create and run a test plan with HTTP Request and uses Apache JMeter to test the API. Also, with this recipe, the API user will get an idea on how to test memory bottlenecks and data limitations for an API.
