Question

I have read here about unit testing with the Surefire plugin and integration testing with the Failsafe plugin, but I am still unclear about how the POMs should look in a Maven project that consists of a parent and multiple child modules, each with their own POM file.

Questions:

• Has anyone implemented integration tests and unit tests in each of their modules?
• If so, would you be so kind as to show your POMs so I have an example of a good working configuration?

Answer 1

See my answer to question: How can I switch between two test suites in Maven 2?
I prefer maven module – very easy to implement and you do not need knowledge about other plugin.

If you using testng you can just define in your parent pom (one place only):

<profile>
    <id>normal</id>
    <activation>
        <activeByDefault>true</activeByDefault>
    </activation>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration>
                    <excludedGroups>integration</excludedGroups>
                </configuration>
            </plugin>
        </plugins>
    </build>
    </profile>
<profile>
    <id>integration</id>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration>
                    <includedGroups>integration</includedGroups>
                </configuration>
            </plugin>
        </plugins>
    </build>
</profile>

Annotate all integration tests by:

@Test(groups="integration")

If you use junit see Category

You run normal test by: mvn clean install integration tests by mvn -Pintegration clean install
