Build API Performance from the Ground Up

Using Unit Tests to Benchmark API Component Performance

Get the Whitepaper


The business logic of most modern applications now relies on some combination of APIs and third-party libraries—which means that the performance of end-to-end transactions is heavily dependent upon the performance of the APIs and components that the application leverages. Given their ability to make or break performance goals, key application components should undergo a rigorous performance evaluation.

Using unit tests to evaluate component performance provides a number of advantages. However, unit-level performance testing is often overlooked because unit testing tools lack the capabilities commonly found in dedicated performance testing tools (e.g., the ability to set up and execute various performance test configurations, monitoring of system and application resources during the test, collecting and analyzing performance test results, etc.).

This paper explains how you can get the best of both worlds by executing unit-level tests with traditional performance testing tools. It also outlines a strategy you can apply to measure and benchmark the performance of the components that your team might integrate into your target application.
