My integration testing tools / frameworks of choice
22 Mar 2026
Share your tools / frameworks as well. There is no right or wrong answer, what would be particularly interesting is the reasons a tool was chosen due to your context and environment.

This can vary a bit depending on technology under test but...
* Component testing - restAssured with JUnit as a runner with TestContainers for mocking.
* Contract testing - Pact is used widely, not sure what PactFlow is though (its the enterprise platform built on top of pact)
* External integration test (with an interface) - Postman or Bruno for exploratory testing, not necessarily at one particular level though.
* External integration test (code) - restAssured again, with a JUnit runner

Let agents spin up stateful API simulations so they can deliver better work, without hitting your live endpoints.

What I learned about influence by becoming a stakeholder
Go beyond with modern integration testing—with faster feedback, simpler debugging, improved scalability and maintainability. Take the step to implement new test types including contract testing of course.
