I'm bit confused with mvn verify
phase. I've created a Spring Boot project (a simple project, without any explicit configurations added). I've created a few JUnit unit tests which are run with both the mvn verify
and mvn test
commands.
There isn't any difference observed in the mvn verify
and mvn test
command output.
What does mvn verify
do different than mvn test
?
Also some posts on Stack Overflow mentions that mvn verify
runs the integration tests. If this is the case then I have few questions.
mvn verify
is supposed to run only the integration tests, then why are unit tests executed with it?First of all, when you run a Maven goal, it will run any previous goal. The order of basic phases is:
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.
