Making Maven run all tests, even when some fail
From the Maven Embedder documentation:
-fae,--fail-at-endOnly fail the build afterwards; allow all non-impacted builds to continue
-fn,--fail-neverNEVER fail the build, regardless of project result
So if you are testing one module than you are safe using -fae.
Otherwise, if you have multiple modules, and if you want all of them tested (even the ones that depend on the failing tests module), you should run mvn clean install -fn.-fae will continue with the module that has a failing test (will run all other tests), but all modules that depend on it will be skipped.
I just found the -fae parameter, which causes Maven to run all tests and not stop on failure.
Either configure Surefire with <testFailureIgnore>true</testFailureIgnore>.
Or on the command line:
mvn install -Dmaven.test.failure.ignore=true
