Is there any way to provide some command-line argument in order to skip all tests but one on some module? So I will not need to change pom.xml every time I will need to run another test?
For example, I want to create build configuration on TeamCity, and provide command-line arguments to run only single test in some module. Next time I will need to change it and run another test, and so on.
Perhaps it is not how CI is intended to be used, but still.
I assume you've read the docs about running a single test under surefire? What they don't tell you is how to do that in a sub-module:
mvn test -Dtest=testname -pl subproject
Where subproject is the project containing that test. From the mvn man page:
-pl,--projects arg Comma-delimited list of specified reactor projects to build instead of all projects. A project can be specified by [groupId]:artifactId or by its relative path.
Other answers I see are not fully complete, for projects that depend on other sub-modules to be built. One option is to run mvn install to have the required jars to be installed into ~/.m2/..., but that option is not very "clean".
Following command will build the sub-modules, and run only the test class that is specified. This is to be run at parent module level. Also, no need to specify sub-module name.
mvn test -DfailIfNoTests=false -Dtest={test_class_name} -am
As an aside, this can also be mvn clean test -Dfa...... I have a habit of always running clean when running tests.
References.. -am will make all the other sub-modules.-DfailIfNoTests=false does not fail the entire process since we are not intending to run tests in other modules.-pl option is not needed since -am is already building everything
