integrationtest
An integration test, sometimes called an integrationtest, is a software testing level focused on verifying that multiple components or systems work together as intended. Unlike unit tests that validate a single component in isolation, integration tests exercise the interfaces and data flows between modules, services, databases, and external dependencies.
By testing interactions, integration tests aim to detect interface mismatches, incorrect data formats, and integration errors
Approaches include incremental strategies such as top-down or bottom-up integration, as well as the big bang
Common practices include defining clear interface contracts, using test doubles (stubs, mocks) when external systems are
Tools and frameworks for integration testing vary by language but often include Java tools like JUnit or
Limitations of integration tests include sensitivity to changes in interfaces or environment setup, potential flakiness, and
Overall, integration testing helps verify that the system behaves correctly when components interact, providing earlier detection
