integration test
In software development, testing that combined components work together correctly.
We check the interfaces between modules in the integration test.
単体試験 is unit testing of individual components, while 結合試験 tests how those components work together.
システム試験 is system testing of the entire integrated system, a broader phase after 結合試験.
Compound of 結合 (integration) and 試験 (test), a direct translation of the English term 'integration test'.
