GWT: The test class 'com.myco.clearing.commons.xml.XMLNodeTest' was not found in module

Question

I have a Maven (3.0.3) / GWT (2.4) project. I'm trying to write some JUnit test cases but running into issues. All my test cases extend GWTTestCase and include this code ...

@Override
public String getModuleName() {
    return "com.myco.clearing.product.ProductPlus";
}

The "ProductPlus.gwt.xml" file is located in my src/main/java directory. To include that in my classpath I have this configured for my surefire-plugin ...

        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.6</version>
            <configuration>
                <additionalClasspathElements>
                    <additionalClasspathElement>${project.build.sourceDirectory}</additionalClasspathElement>
                    <additionalClasspathElement>${project.build.testSourceDirectory}</additionalClasspathElement>
                </additionalClasspathElements>
                <useManifestOnlyJar>false</useManifestOnlyJar>
                <forkMode>always</forkMode>
                <systemProperties>
                    <property>
                        <name>gwt.args</name>
                        <value>-out \${webAppDirectory}</value>
                    </property>
                </systemProperties>
            </configuration>
        </plugin>

However, upon running "mvn clean test", I get all these errors, including this one ...

This is a bizarre error because the class in question is in my src/test/java directory, which I have included as an "additionalClassPathElement" (above). What other configurations do I need to make to correct this error? - Dave

Answer 1

The package for your test must be in the client classpath for the module specified. Based on the module's name, your test probably belongs in the com.myco.clearing.product.client package, or a subpackage of that.
