We have a set of integration tests, which all end with IT. Out of those, there is some specific subset, which we would like to execute separately. Let's say their names end with SpecialIT. So what we want to achieve is two configurations of the failsafe plugin:
To execute all tests, ending with IT, but not with SpecialIT -> this is easy. Just normal inclusion and exclusion by those names.
To execute all tests, ending with SpecialIT, but not all others ...IT.
I thought it would be natural to create some dedicated profile and use a separate failsafe configuration with a negative lookbehind regex for that, so ended up with this configuration (had to use < instead of <, as that one is not allowed there):
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<configuration>
<excludes>
<exclude>%regex[.*(?<!Special)IT.*]</exclude>
</excludes>
<includes>
<include>**/*SpecialIT.*</include>
</includes>
</configuration>
</plugin>
But when I try to run this - I'm getting the following error:
Exclamation mark not expected in 'exclusion': %regex[.*(?<!Special)IT.*]
Reading the documentation of the failsafe plugin - I see this:
The syntax in parameter excludes and excludesFile should not use (!).
So the question is: is there any other way to achieve this, without, let's say, renaming all our integration tests into ...StandardIT and ...SpecialIT?
I was thinking in the direction of tags, test suit names or smth., but in our project we currently have a mix of JUnit5, JUnit4 and Spock (Groovy) tests, so it becomes not so straightforward.
P.S. If I just use this configuration - all IT tests are getting disabled and nothing is executed:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<configuration>
<excludes>
<exclude>**/*IT.*</exclude>
</excludes>
<includes>
<include>**/*SpecialIT.*</include>
</includes>
</configuration>
</plugin>
Thanks to #andrey-b-panfilov, I realized that my problem was that I somehow was under an impression (based on this) that all ...IT tests are always executed by default... But this is, of course, only until the <includes> is overwritten. So, the solution is eventually to just define the following two configurations:
To execute all but SpecialIT:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<configuration>
<includes>
<include>**/*IT.*</include>
</includes>
<excludes>
<exclude>**/*SpecialIT.*</exclude>
</excludes>
</configuration>
</plugin>
To execute only SpecialIT:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<configuration>
<includes>
<include>**/*SpecialIT.*</include>
</includes>
</configuration>
</plugin>
My company is in the middle of revamping the java code that has been written till now. Earlier there were some test cases written, but they were not maintained. As a result they are failing.
I have inherited this project, but currently have to make do with skipping all the tests.
I want to start by picking some unit test cases within a module fix them and add it to the suite of test cases that are being run. Over a period of time, I want to cover all the tests in my project.
I have tried the following plugin configuration in my POM file, but it is not working. Is there something I am missing ?
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M5</version>
<configuration>
<skipTests>${skipTests}</skipTests>
<excludes>
<exclude>**/*Test.java</exclude>
</excludes>
<includes>
<include>**/ParticularSubModuleTest.java</include>
</includes>
</configuration>
</plugin>
I am facing an issue with Maven which nowhere on internet I could find an answer for it. appreciate if anyone can help me with it. I aiming to test 2 testng files sent as parameter to POM as:
mvn clean test -DsuiteXmlFiles=1.xml,2.xml
and the POM file is:
<plugins>
<!-- Following plugin executes the testng tests -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<!-- Suite testng xml file to consider for test execution -->
<suiteXmlFiles>
<suiteXmlFile>${suiteXmlFile}</suiteXmlFile>
</suiteXmlFiles>
<testFailureIgnore>true</testFailureIgnore>
</configuration>
</plugin>
<!-- Compiler plugin configures the java version to be usedfor compiling
the code -->
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
</plugins>
but, when i run, it ONLY runs the 2.xml file and runs it twice!!!
tried many options but no matter what is the second xml file it totally ignores the first and runs the second one twice.
can anyone please help?
thanks
Your surefire plugin should look like below
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.15</version>
<configuration>
<suiteXmlFiles>${file}</suiteXmlFiles>
<skipTests>false</skipTests>
</configuration>
</plugin>
Pay close attention to <suiteXmlFiles>${file}</suiteXmlFiles>
So now you can pass in multiple suite files via
mvn clean test -Dfile=src/test/resources/suite-one-with-execution.xml, src/test/resources/suite-two-with-execution.xml
For more details you can refer to my blog post here.
finally understood where the issue was, for some reason i still dont know why, the Suite name in xml files should be not same as each other!!
Is it possible to tell Maven to execute every testng test in new JVM instance (fork) in serial mode, i.e. one by one.
The configuration below works for junit, but not works for testng
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.9</version>
<configuration>
<forkMode>always</forkMode>
</configuration>
Does anybody know how to set for testng?
#ben75, Thanks for your answer, But it doesn't work for me.
The key point is we use suiteXmlFiles to specify which case to run, and if we use suiteXmlFiles, the forkMode or (forkCount resuseForks) don't work.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.16</version>
<configuration>
<includes>
<include>**/Test*.java</include>
</includes>
<forkMode>always</forkMode>
</configuration>
</plugin>
This configuration works for me.
You can use this
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.16</version>
<configuration>
<forkCount>1</forkCount>
<reuseForks>false</reuseForks>
...
It's a very expensive configuration (i.e. it will take a long time to run your tests... so it's better to not use it, but you probably have some (good ?) reasons to use it).
This solution is the way to go since version 2.14, so I suggest you to upgrade your surefire-plugin version.

I have a multi-module maven project with both integration and unit tests in the same folder (src/test/java). Integration tests are marked with #Category(IntegrationTest.class). I want to end up with the following setup:
If I run mvn install, I want all tests to compile, but I do not want to execute any.
If I run mvn test, I want all tests to compile, but execute only unit tests.
If I run mvn integration-test, I want to compile and execute all tests.
The important point is, I want this configured in the pom.xml without any extra commandline arguments.
Currently I came up with the following setup in my parent pom.xml, where the only problem is #1, where all tests are executed:
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>

</configuration>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
</build>
All child modules have the following plugin configuration in their pom.xml, which I believe should inherit from the parent pom:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
</plugin>
<plugin>
<artifactId>maven-failsafe-plugin</artifactId>
</plugin>
</plugins>
</build>
I tried using <skipTests>true</skipTests>, but it disables test execution for all goals, which is not what I want (violates #2 and #3). It is also quite weird, that mvn test honors the skipTests=true option...why would I want to run it in the first place??
After hours of googling and trying different combinations, I am hesitant whether it is even possible to not run tests in mvn install, while at the same time run them in mvn test. I hope someone proves this wrong. ;)
I am also willing to accept a solution, where mvn install would execute only unit tests, but I don't think it makes much difference.
It sounds like you didn't understand the concept of the build life-cycle in Maven. If you run mvn install all life-cycle phases (including the install phase itself) run before the install phase. This means running the following phases:
validate
initialize
generate-sources
process-sources
generate-resources
process-resources
compile
process-classes
generate-test-sources
process-test-sources
generate-test-resources
process-test-resources
test-compile
process-test-classes
test
prepare-package
package
pre-integration-test
integration-test
post-integration-test
verify
install
which means in other words the test as well as integration-test life-cycle phases are included. So without any supplemental information it's not possible to change the behaviour as you wish it.
It could be achieved by using a profile in Maven:
<project>
[...]
<profiles>
<profile>
<id>no-unit-tests</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<skipTests>true</skipTests>
</configuration>
</plugin>
</plugins>
</build>
</profile>
</profiles>
[...]
</project>
So your first requirement:
If I run mvn install, I want all tests to compile, but I do not want to execute any.
can be achieved by using the following:
mvn -Pno-unit-test test
If I run mvn test, I want all tests to compile, but execute only unit tests.
This can simply achieved by using the plain call:
mvn test
cause the integration tests phase is not run (see the build life cycle).
If I run mvn integration-test, I want to compile and execute all tests.
This means running the default which includes running the test phase which will run the unit tests (maven-surefire-plugin) and furthermore running the integration test which are handled by the maven-failsafe-plugin. But you should be aware that if you like to call the integration tests you should using the following command:
mvn verify
instead, cause you missed the post-integration-test phase in your previous call.
Apart from the above you should follow the naming conventions for unit and integration tests where unit tests should be named like the following:
<includes>
<include>**/*Test*.java</include>
<include>**/*Test.java</include>
<include>**/*TestCase.java</include>
</includes>
and integration tests should be named like the following:
<includes>
<include>**/IT*.java</include>
<include>**/*IT.java</include>
<include>**/*ITCase.java</include>
</includes>
I hope you have configured the maven-failsafe-plugin like the following which is needed to bound the maven-failsafe-plugin to the correct life-cycle-phases:
<project>
[...]
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.15</version>
<executions>
<execution>
<goals>
<goal>integration-test</goal>
<goal>verify</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
[...]
</project>
as you correctly did, but you should be aware that the include tags work on the source code (.java) and not on the compiled names (.class). I wouldn't use the Category annotation, just simply using the naming conventions makes the pom simpler and shorter.
According to the Failsafe Plugin documentation
mvn install -DskipITs
is what you want.
What OP stated in his question:
If I run mvn install, I want all tests to compile, but I do not want
to execute any.
If I run mvn test, I want all tests to compile, but execute only unit tests.
If I run mvn integration-test, I want to compile and execute all tests.
is perfectly valid and extremely easy to achieve.
EDIT: except first condition, which acts againts the maven nature. The best way here would be simply do mvn install -DskipTests
All you need is following snippet in pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.17</version>
<executions>
<execution>
<id>integration-tests</id>
<goals>
<goal>integration-test</goal>
<goal>verify</goal>
</goals>
</execution>
</executions>
</plugin>
and to stick to the maven naming conventions for unit and integration tests (as #khmarbaise already stated). So generally name you integration tests with IT suffix (for example MyIntegrationTestIT.java) and let maven-failsafe do its job.
In that way, you do not even need JUnit categories (although sometimes they can be quite useful).
That's it :)
mvn test executes only unit tests
mvn integration-test executes all tests
mvn failsafe:integration-test runs only integration tests
mvn clean verify when you want to be sure, that whole project just works
Some personal advices
Keeping integration tests separately from unit tests lets you easily run within your IDE all tests in some package. Usually additional directory called test-integration (or integrationtest) is used for this purpose.
This is also easy to achieve with maven:
<plugin>
<!-- adding second test source directory (just for integration tests) -->
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.9.1</version>
<executions>
<execution>
<id>add-integration-test-source</id>
<phase>generate-test-sources</phase>
<goals>
<goal>add-test-source</goal>
</goals>
<configuration>
<sources>
<source>src/test-integration/java</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>
And then move your integration tests to that directory. It should look like:
src
main
test
test-integration
Integration tests usually needs more memory:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
...
<configuration>
<argLine>-Xmx512m -XX:MaxPermSize=256m</argLine>
</configuration>
</plugin>
This post explains how to skip integration tests, no matter what plugin you are using for these tests.
Basically, what you do is define a profile and put all your integration-tests related xml code inside that profile. Than you activate it when a property -DskipIntegrationTests is missing.
You can do the same for unit tests: write a profile and activate it when -DskipUnitTests is missing.
Then, you could do:
mvn install -DskipIntegrationTests -DskipUnitTests # (runs install without any tests)
mvn test # (runs unit tests)
mvn post-integration-test # (runs all tests)
The maven-failsafe-plugin docs has a section titled "Skipping by Default."
Sadly, the steps that page describes don't work as written. However, a slight change to those steps will make it work:
In the properties section of pom.xml, add this:
<skipITs>true</skipITs>
Then add the skipTests property to the plugin section of maven-failsafe-plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<configuration>
<skipTests>${skipITs}</skipTests>
</configuration>
<executions>
<execution>
<goals>
<goal>integration-test</goal>
<goal>verify</goal>
</goals>
</execution>
</executions>
</plugin>
So now, an mvn install by default will execute unit tests, but not integration tests.
But an mvn install -DskipITs=false will execute both unit tests and integration tests.
Footnote: Bad documentation played a big part on why Maven was so disliked for such a long time.
mvn test-compile does exactly what you are looking for. You can simply replace mvn install with mvn test-compile and you are done. No need to customise the pom file or anything. The below linked question is similar around #1:
Maven - How to compile tests without running them ?
mvn test-compile should be accepted as the best answer as Maven supports exactly what you want to do natively and without any magic. You would end up with this:
If I run mvn test-compile, I want all tests to compile, but I do not want to execute any.
If I run mvn test, I want all tests to compile, but execute only unit tests.
If I run mvn integration-test, I want to compile and execute all tests.
Don't specify the execution step(s) in the configuration of the failsafe plugin. E.g.
<plugins>
<plugin>
<artifactId>maven-failsafe-plugin</artifactId>
<version>3.0.0-M3</version>
</plugin>
</plugins>
Now, you specifically need to call mvn failsafe:integration-test to run the integration tests; they will be skipped in other mvn targets.
