First of all, when you run a Maven goal, it will run any previous goal. The order of basic phases is:
- Validate
- Compile
- Test
- Package
- Verify
- Install
- Deploy
If you run Test, Maven will execute validate, compile and test. Based on this, the first point is that verify includes test.
Based on official documentation:
-
TEST – test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed
-
VERIFY – run any checks on results of integration tests to ensure quality criteria are met
To run unit tests, the Surefire plugin is recommended. And Failsafe for integration tests.
The verify command executes each default lifecycle phase in order (validate, compile, package, etc.), before executing verify. In most cases the effect is the same as package. However, in case there are integration tests, these will be executed as well. And during the verify phase some additional checks can be done, e.g. if your code is written according to the predefined checkstyle rules.
Conclusion: if you want to run your integration tests and check it, use verify. If you only want to run unit tests, use test.
My personal advice: if in doubt, use verify.
