Integration test

Meaning in software engineering, with examples

/ˌɪntɪˈɡreɪʃən test/nounCommon term

In software engineering, integration test means: A test that checks how several parts of a system work together, for example your code with a real database or another service.

In Turkish: entegrasyon testi, bütünleştirme testi

How it is used

Sits between unit tests and end-to-end tests. Integration tests are slower than unit tests but catch problems in the connections between parts, such as wrong queries or changed API formats.

Example sentences

  1. The unit tests passed, but the integration test failed against the real database.

  2. We run integration tests in Docker so every developer gets the same setup.

Common collocations

  • write an integration test
  • run integration tests
  • integration test suite
  • integration testing
  • unit testA small automated test that checks one function or class on its own, separate from the database, the network and the rest of the system.
  • end-to-end testA test that runs a complete user journey through the real system, for example opening the site, logging in and placing an order, to check that everything works together.
  • mockA fake version of a real object or service used in tests, so you can control its behavior and check how your code uses it. Also a verb: to mock a service.
  • test coverageA measure, often a percentage, of how much of the code is run by automated tests. It shows which parts are tested and which are not.
