Maven doesn't execute any unit test

Question

I am using Maven with multi-modules. There are 3 projects.

foo(the parent project)
foo-core
foo-bar

I configure all the dependencies and plugins in foo's pom:

<modules>
    <module>../foo-core</module>
    <module>../foo-bar</module>
</modules>

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.11</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            ...
        </dependency>
    </dependencies>
</dependencyManagement>

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>2.3.1</version>
                <configuration>
                    <source>1.6</source>
                    <target>1.6</target>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.14.1</version>
                <dependencies>
                    <dependency>
                    <groupId>org.apache.maven.surefire</groupId>
                    <artifactId>surefire-junit47</artifactId>
                    <version>2.14.1</version>
                    </dependency>
                </dependencies>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

There are several base classes and util classes for unit test in foo-core, so I add the maven-jar-plugin in foo-core project to make it available to foo-bar:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>2.3.1</version>
            <executions>
               <execution>
                   <goals>
                       <goal>test-jar</goal>
                   </goals>
               </execution>
            </executions>
        </plugin>
    </plugins>
</build>

When I execute test goal, I got the result as follow:

-------------------------------------------------------
 T E S T S
-------------------------------------------------------
parallel='none', perCoreThreadCount=true, threadCount=2, useUnlimitedThreads=false

Results :

Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

I do got tests in my projects. But why it doesn't run any of them?

Rename test files from **Tests.java to **Test.java or add the following configuration to pom.xml

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>2.14.1</version>
  <configuration>
    <includes>
      <include>**/*Tests.java</include>
    </includes>
  </configuration>
</plugin>
