 ### What is Integration Testing ?
 
+**Integration testing** is a level of software testing that checks whether separate components of an application, such as internal modules, APIs, databases, message queues and third-party services, work correctly together. For a full walkthrough with a test plan template, real examples and tools, read our complete [integration testing guide](https://keploy.io/blog/community/integration-testing-a-comprehensive-guide).

 Integration testing is a software testing process that combines individual software modules into larger subsystems or components to evaluate their interactions. It is conducted after unit testing and before system testing. The primary objective of integration testing is to detect defects that occur when different modules are integrated and interact.
