API testing

We make sure the API your app, partners and other systems use to exchange data keeps working correctly after every change.

API tests are fast and reliable, and they catch real problems because they check exactly what your partners and applications use. We write them from the API description, so the description and the tests always stay in sync. When a developer changes something in the API, the tests immediately show which app or partner would stop working, before the change goes live.

What you get

  • Fast checks of the most important API functions before every release
  • Tests that immediately show when a change breaks your mobile app or a partner integration
  • Checks that every API response looks exactly the way the documentation says it should
  • Checks of access control, request limits and repeated requests, so an order or payment is never recorded twice
  • Testing against the API description before the server is finished, so your app and partners can start work sooner
  • Tests that run automatically on every code change

When to call us

  • Your API has dozens of endpoints and has never been tested systematically
  • Your mobile app or a partner system regularly stops working after your changes
  • Several teams work on systems that depend on each other, and you need an agreement that is checked automatically
  • The API changes often and nobody knows who the next change will affect

How we work

We start by reviewing your existing APIs and their documentation. Then we build a core set of quick checks, followed by dedicated tests for the most important integrations with partners and apps. Finally we set the tests to run on every code change and keep adding new ones as the API gains new features.

Frequently asked questions

We can. Karate is a good fit for teams working in Java or Kotlin, and RestAssured for teams that work only in Java. Most of the time, though, we use Postman and Newman because most teams already know them, along with Pact for checking agreements between systems.
