[FIXED] How to import JUnit tests from one Maven project into another?

Issue

I have two Eclipse projects A and B that I use to run Selenium tests with JUnit.

• Project A tests a web app, so it contains tests that are divided into multiple packages each with their own test suite class (one package for each feature).
• Project B tests an application that uses A's web app but adds new features, so it contains its own tests but must also be able to reuse tests from A in its own test suite class when features are reused.

In both projects, my test code is located under src/test/java, because I need to be able to test both separately.

The problem is that I can't reuse tests from A in B because I can't import the test packages from A. I tried to fix this by placing A's packages in its src/main/java folder instead, but that means I can no longer run A's test suites separately because it no longer has any tests to speak of.

What I want to do is to simply have tests in my Project A, that I can execute, but to be able to reuse those test classes in Project B without duplicating code. How can I do this?

Solution

You can package your test code in its own artifact

 <!-- Packaging of test classes in JAR file -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>test-jar</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

You can then import the dependency where you need it
