mvn 测试非常非常慢

Question

I have ten Maven projects and for each project I have to perform a specific test case for n times (with n very large). To run the test case I run the command mvn -Dtest=className#methodName test , but it is extremely slow. I can't modify the project pom.

Is there a faster command that works like the one written above?

I found this command https://maven.apache.org/surefire/maven-surefire-plugin/examples/rerun-failing-tests.html , but it stops at the first success of the test.

Answer 1

Calling mvn -Dtest=className#methodName test multiples times is not a good idea because each time, all phases before test are executed before actually running the test.

If you really want to run the same test multiple times, try mvn -Dtest=className#methodName surefire:test . But note that it would be better to dig into the tests to make sure they are deterministic instead of running each and every test a hundred times.
