How do I get my Maven Integration tests to run

I have a maven2 multi-module project and in each of my child modules I have JUnit tests that are named Test.java and Integration.java for unit tests and integration tests respectively. When I execute:

mvn test

all of the JUnit tests *Test.java within the child modules are executed. When I execute

mvn test -Dtest=**/*Integration

none of the Integration.java tests get execute within the child modules.

These seem like the exact same command to me but the one with the -Dtest=/*Integration** does not work it displays 0 tests being run at the parent level, which there are not any tests

You should use maven surefire plugin to run unit tests and maven failsafe plugin to run integration tests.

Please follow below if you wish to toggle the execution of these tests using flags.

Maven Configuration

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <skipTests>${skipUnitTests}</skipTests>
            </configuration>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-failsafe-plugin</artifactId>
            <configuration>
                <includes>
                    <include>**/*IT.java</include>
                </includes>
                <skipTests>${skipIntegrationTests}</skipTests>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>integration-test</goal>
                        <goal>verify</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

        <properties>
            <skipTests>false</skipTests>
            <skipUnitTests>${skipTests}</skipUnitTests>
            <skipIntegrationTests>${skipTests}</skipIntegrationTests>
        </properties>

So, tests will be skipped or switched according to below flag rules:

Tests can be skipped by below flags:

  • -DskipTests skips both unit and integration tests
  • -DskipUnitTests skips unit tests but executes integration tests
  • -DskipIntegrationTests skips integration tests but executes unit tests

Running Tests

Run below to execute only Unit Tests

mvn clean test

You can execute below command to run the tests (both unit and integration)

mvn clean verify

In order to run only Integration Tests, follow

mvn failsafe:integration-test

Or skip unit tests

mvn clean install -DskipUnitTests

Also, in order to skip integration tests during mvn install, follow

mvn clean install -DskipIntegrationTests

You can skip all tests using

mvn clean install -DskipTests

You can follow the maven documentation to run the unit tests with the build and run the integration tests separately.

<project>
    <properties>
        <skipTests>true</skipTests>
    </properties>
    [...]
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-failsafe-plugin</artifactId>
                <version>2.20.1</version>
                <configuration>
                    <skipITs>${skipTests}</skipITs>
                </configuration>
            </plugin>
        </plugins>
    </build>
    [...]
</project>

This will allow you to run with all integration tests disabled by default. To run them, you use this command:

mvn install -DskipTests=false

I didn't need to do all those setups suggested in other answers and I can run unit tests or integration tests separately.

What I did was:

  1. add the config bellow to pom.xml in order to instruct maven where are the integration tests files (the java code and the resources files):
<plugins>
    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>build-helper-maven-plugin</artifactId>
        <executions>
            <execution>
                <id>add-integration-test-source</id>
                <phase>generate-test-sources</phase>
                <goals>
                    <goal>add-test-source</goal>
                </goals>
                <configuration>
                    <sources>
                        <source>src/integration-test/java</source>
                    </sources>
                </configuration>
            </execution>
            <execution>
                <id>add-integration-test-resource</id>
                <phase>generate-test-resources</phase>
                <goals>
                    <goal>add-test-resource</goal>
                </goals>
                <configuration>
                    <resources>
                        <resource>
                            <directory>src/integration-test/resources</directory>
                        </resource>
                    </resources>
                </configuration>
            </execution>
        </executions>
    </plugin>
</plugins>

  1. Name the integration test files with the "IT" suffix, like "MyTestIT.java"

  2. Execute only the integration tests with this command:

    mvn failsafe:integration-test failsafe:verify

In the command above "failsafe:integration-test" will execute the *IT.java files and "failsafe:verify" will tell maven to check if any of the integration tests ran previously have failed. If you don't use 'failsafe:verify' the mvn command will exit with success even if one test has failed.

  1. To run only the unit tests, run:

    mvn test
