Rest Assured
API Testing
Open source
<What you get/>
API tests in the same repository, language and pipeline as your UI suite
Genuinely data-driven coverage across boundary and malformed inputs
Tests written against the documented contract where a specification exists
One build and one report rather than API coverage in a separate tool
What it is
REST Assured is a Java library for testing REST services with a readable given/when/then syntax. Its advantage over a standalone API tool is proximity: API and UI tests live in one repository, share utilities and test data, and run through the same build. That matters when a failing end-to-end test needs to be traced back to the service beneath it.
How PerfectQA uses Rest Assured
Rest Assured is where API coverage goes when it needs to live in the Java build rather than in a separate tool. It puts API tests in the same repository, the same language and the same pipeline as the rest of the suite, which means one build, one report and one set of conventions instead of API coverage sitting in a parallel universe. We use it heavily for data-driven work — the same endpoint exercised across a table of inputs including the malformed and boundary cases that matter most — because that is awkward in collection-based tools and natural here. Its fluent given/when/then structure keeps request setup, execution and assertion visually separate, which matters when a test is checking a dozen response fields. We pair it with Swagger definitions where they exist so tests are written against the documented contract rather than against whatever the service currently happens to return.
