Suppose you have a large number of unit test cases and you don't want them to be executed all at the same time during Maven build. You can simply achieve it via annotation @Category.


1. Create empty class FastTests and SlowTests.

2. In your test case class, categorize your test method using @Category annotation:

3. Append the following code to your pom.xml:
<profiles>
<profile>
<id>SlowTests</id>
<properties>
<testcase.groups>com.sap.SlowTests</testcase.groups>
</properties>
</profile>
<profile>
<id>FastTests</id>
<properties>
<testcase.groups>com.sap.FastTests</testcase.groups>
</properties>
</profile>
</profiles>

<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.13</version>
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit47</artifactId>
<version>2.13</version>
</dependency>
</dependencies>
<configuration>
<groups>${testcase.groups}</groups>
</configuration>
</plugin>
</plugins>
</build>

4. In my project, by default all 7 test methods will be executed during Maven build:


Suppose you only want to execute unit test belonging to category "SlowTests", use the following command line:

Since now I only marked one method with annotation SlowTests, only one test method is executed:

If you would like to execute all unit tests EXCEPT @SlowTests, simply add another profile in pom.xml:
<profile>
<id>NonSlowTests</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<excludedGroups>com.sap.SlowTests</excludedGroups>
</configuration>
</plugin>
</plugins>
</build>
</profile>


Before test, in order to prove that Slow method is NOT really executed, I add a system.out.println in each method:


Use command line: mvn test -P NonSlowTests

From console output, I can ensure that the method with @Category(SlowTests.class) is NOT executed at all.
