With junit 4, I add an @Ignore
annotation when I want to do that. This would work for you, unless you want to only sometimes ignore the test, or only ignore it when the build runs from maven. If this is the case, then I would ask "Why?"
Tests should be consistent, they should be portable, and they should always pass. If a specific test is problematic I would consider re-writing it, removing it entirely, or moving it to a different test suite or project.
You can specify an exclusion pattern to -Dtest
option by prefixing it with an !
(exclamation mark). E.g.,
mvn -Dtest=\!FlakyTest* install
Found it in here and verified to be working. E.g., I was able to skip this flaky Jenkins test by using:
mvn -Dtest=\!CronTabTest* package
It is normal that integration tests need to be excluded but unit tests need to be included. To achieve this I suggest naming all integration tests with a postfix IntegrationTest (e.g. AbcIntegrationTest.java).
and then in your maven build put the following:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<excludes>
<exclude>**/*IntegrationTest.java</exclude>
</excludes>
</configuration>
</plugin>
When you build with this all the integration tests wil be excluded, but all other tests (Unit test for example) are run. Perfect :-)
For more info on exclusing and including tests during the test run, read
http://maven.apache.org/surefire/maven-surefire-plugin/examples/inclusion-exclusion.html
PS To exlude one single test you simply need to explicitly name it in the exclude list. Easy.
Have a look at this solution, using @Category
annotations
public class AccountTest {
@Test
@Category(IntegrationTests.class)
public void thisTestWillTakeSomeTime() {
...
}
@Test
@Category(IntegrationTests.class)
public void thisTestWillTakeEvenLonger() {
...
}
@Test
public void thisOneIsRealFast() {
...
}
}
Which you then run using a test suite:
@RunWith(Categories.class)
@IncludeCategory(SlowTests.class)
@SuiteClasses( { AccountTest.class, ClientTest.class })
public class LongRunningTestSuite {}
i think this should work if using this command:
mvn archetype:create -DgroupId=test -DartifactId=test
(for test change pom.xml and test-class to the following and use mvn install)
pom.xml

}
If you want to use the CLI to exclude one single test you should use the -Dtest
and -Dit.test
flags.
Be careful to reset the defaults. When you are using the !
notation all the defaults are erased and you should put them back. For normal tests executed by surefire
you should add *Test, Test*, *Tests, *TestCase
, while for integration tests executed by failsafe
you should add IT*, *IT, *ITCase
.
You can find more info here https://maven.apache.org/surefire/maven-surefire-plugin/examples/inclusion-exclusion.html (normal tests)
and here https://maven.apache.org/surefire/maven-failsafe-plugin/examples/inclusion-exclusion.html (integration tests)
-Dit.test='!ITsometestIT, IT*, *IT, *ITCase'
A complete mvn
command could be this one:
mvn -e -B -Dtest='!unitTestABC, *Test, Test*, *Tests, *TestCase' -Dit.test='!ITintegrationTestABCIT, IT*, *IT, *ITCase' -DfailIfNoTests=false clean install
Remember to use '
and NOT "
. When using double quotes any !
inside them will be evaluated by bash
.
Remember also that integration tests are not run when mvn test
. With mvn verify
only integration tests will be run and not unit tests
