Is there a way in Maven to compile the tests without running them ? I want to use the IDE to run specific tests and not all of them.

You should probably either edit the question or change the accepted answer. – Diplomate 1/6, 2017 at 5:44

you can try to use parameter -DskipTests

Maven Surefire Plugin # skipTests

In netbeans, that is what i was doing. I see the following mvn -Dmaven.test.skip=true -Dnetbeans.execution=true clean install then i see the following – Xylophagous 22/1, 2011 at 15:57

[compiler:testCompile] Not compiling test sources [surefire:test] Tests are skipped. Atleast using netbeans looks like if tests are skipped it does not compile test sources – Xylophagous 22/1, 2011 at 15:58

never mind, even though the logs say that, it still seems to compile test files. – Xylophagous 22/1, 2011 at 16:31

this leads to skipping tests completely: execution as well as compilation, see the correct answer below: test-compile. I use it with mvn clean compile test-compile in Eclipse – Leeannaleeanne 26/6, 2012 at 12:32

@Leeannaleeanne you're right this aswer is not so clever... please accept answer bellow, so a can delete this one – Willywillynilly 2/7, 2012 at 15:12

@Leeannaleeanne You are talking about the skip option, aren't you? See this answer. – Peanuts 26/2, 2015 at 11:9

@Willywillynilly As far as I know this is the best solution for the question! Until now I used 'maven.test.skip=true' which produces missing test dependencies in cases where tests are not necessary. – Misapply 26/6, 2015 at 8:30

for some reason, tests still run if -DskipTests is set. – Peel 12/2, 2016 at 21:32

you were supposed to delete the answer ( ͡° ͜ʖ ͡°) – Swordsman 18/2, 2019 at 12:30

According with the documentation -DskipTests compiles the test classes but does not execute them (or the test classes are skipped for execution) - to avoid compilation and execution should be used: -Dmaven.test.skip=true – Diversity 28/8, 2021 at 3:40

How about the test-compile lifecycle phase? It doesn't require any test skipping, because it occurs before the test phase. I.e.,

$ mvn test-compile

And done.

Introduction to the Build Lifecycle explains further.

Just curious, what is the advantage of test-compile over -DskipTests? - according with the documentation -DskipTests compiles the test classes but does not execute them (or the test classes are skipped for execution) - so according with It doesn't require any test skipping - should I assume that is expensive? – Diversity 28/8, 2021 at 3:30

-DskipTests is not a Maven lifecycle goal; it's just an option to set. You could run lots of goals with -DskipTests. The OP asked how to compile them without running them, so this satisfies that. I don't see any reason to think skipping tests would be expensive, but it does seem useless to run the test goal and use -DskipTests. – Sloth 31/8, 2021 at 5:56

When that is done, is there a way to continue from this point? Without compiling again? Just running the tests next? – Searcy 16/10, 2021 at 8:15

If you later execute e.g., mvn test, Maven will execute all of its lifecycle phases again, but as long as you haven't run clean, then your build artifacts will still be present and should be up-to-date, making the process much faster. Try it for yourself by running mvn test-compile; mvn test vs mvn test-compile; mvn clean test – Sloth 20/10, 2021 at 4:36

To just compile the tests and code, without running them, just do:

mvn test-compile

I think test-compile includes compile – Antilogism 1/2, 2019 at 18:34

When executing a goal that will include the testing phase (such as package), you can do two things:

Use the command mvn -DskipTests=true package. This will compile all tests but not run them.
Or mvn -Dmaven.test.skip=true package. This will not compile or run the test branch.
