Maven separate Unit Test and Integration Tests

Question

UT = Unit Tests IT = Integration Tests. All my Integration test classes are annotated with @Category(IntegrationTest.class)

My goal is:

mvn clean install => runs UT and not IT

mvn clean install -DskipTests=true => no tests are executed

mvn clean deploy => runs UT and not IT

mvn clean test => runs UT and not IT

mvn clean verify => runs UT and IT

mvn clean integration-test => runs IT and UT are not executed

mvn clean install deploy => runs UT and not IT

pom properties:

<junit.version>4.12</junit.version>
<surefire-plugin.version>2.18.1</surefire-plugin.version>
<failsafe-plugin.version>2.18.1</failsafe-plugin.version>

1. Compiler:

   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-compiler-plugin</artifactId>
       <version>2.5.1</version>
       <configuration>
           <source>1.8</source>
           <target>1.8</target>
           <compilerArgument>-Xlint:all</compilerArgument>
           <showWarnings>true</showWarnings>
           <showDeprecation>true</showDeprecation>
       </configuration>
   </plugin>
   

2. Unit Tests:

   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-surefire-plugin</artifactId>
       <version>${surefire-plugin.version}</version>
       <configuration>
           <excludedGroups>com.xpto.IntegrationTest</excludedGroups>
       </configuration>
   </plugin>
   

3. Integration Tests:

   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-failsafe-plugin</artifactId>
       <version>${failsafe-plugin.version}</version>
       <configuration>
           <groups>com.xpto.IntegrationTest</groups>
       </configuration>
       <executions>
           <execution>
               <goals>
                   <goal>integration-test</goal>
               </goals>
               <configuration>
                   <includes>
                       <include>**/*.class</include>
                   </includes>
               </configuration>
           </execution>                
       </executions>              
   </plugin>        
   

My results are:

mvn clean install => OK

mvn clean install -DskipTests=true => OK

mvn clean deploy => runs UT and not IT

mvn clean test => OK

mvn clean verify => NOK ... only UT are executed but IT also needs to be executed

mvn clean integration-test => NOK ... UT are executed and should not and IT aren't executed but should be executed

mvn clean install deploy => OK

The solution is this:

  <build>
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-surefire-plugin</artifactId>
          <version>2.19.1</version>
        </plugin>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-failsafe-plugin</artifactId>
          <version>2.19.1</version>
        </plugin>
      </plugins>
    </pluginManagement>
   <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.6.1</version>
        <configuration>
          <source>1.7</source>
          <target>1.7</target>
        </configuration>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
          <skip>${surefire.skip}</skip>
        </configuration>
        <executions>
          <execution>
            <goals>
              <goal>integration-test</goal>
              <goal>verify</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.12</version>
      <scope>test</scope>
    </dependency>
  </dependencies>

This will let you control which is executed.

running UT and IT's:

mvn clean verify

running IT's but NOT UT's

mvn clean verify -Dsurefire.skip=true 

running UT but not IT's:

mvn clean verify -DskipITs=true 

You need to follow the naming conventions of the plugins which makes life easier.

Naming conventions for maven-surefire-plugin (unit tests). Naming conventions for maven-failsafe-plugin (integration tests).
