运行JUnit 4测试与FailSafe和SureFire插件并行

Question

We have a profile created in maven to run our Selenium junit4 type tests and below is the snippet of it without the executions tag.

<profile>
    <id>selenium-tests</id>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-failsafe-plugin</artifactId>
                <version>2.11</version>
                <dependencies>
                    <!-- Force using the latest JUnit 47 provider -->
                    <dependency>
                        <groupId>org.apache.maven.surefire</groupId>
                        <artifactId>surefire-junit47</artifactId>
                        <version>2.11</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <parallel>classes</parallel>
                    <threadCount>5</threadCount>
                    <forkMode>pertest</forkMode>
                    <useManifestOnlyJar>false</useManifestOnlyJar>
                    <redirectTestOutputToFile>true</redirectTestOutputToFile>
                    <skip>false</skip>
                    <includes>
                         <include>**/regtests/*.java</include>
                    </includes>
                </configuration>
            </plugin>
        </plugins>
    </build>
</profile>

And my TestClass looks like this.

@RunWith(HTMLSourceDumperJUnit4Runner.class) //Our own Runner
public class MyTestClass extends Assert {

     private int x = 1;
     private int y = 1;

     @Test
     public void testAddition() {
         int z = x + y;
         assertEquals(2, z);
     }

}

When I run this testclass through the failsafe plugin 2.11 with parallel configuration it fails with the following error.

java.lang.Exception: No runnable methods

Is there anything I'm missing here. If I'm lagging any information for this post, please post back.

Answer 1

According the the maven docs on the plugin, specifically the <includes> tag. The test class name patterns are: **/IT*.java , **/*IT.java , and **/*ITCase.java . So you'll want to change to name of the class to MyIT or MyITCase or something like that.

Answer 2

There appears to be a bug in surefire 2.11. It does not like to function with

<useManifestOnlyJar>false</useManifestOnlyJar>

I filed a bug. http://jira.codehaus.org/browse/SUREFIRE-819
