GWT：在模块中找不到测试类'com.myco.clearing.commons.xml.XMLNodeTest'

Question

我有一个Maven (3.0.3)/GWT(2.4)项目。我试图写一些JUnit测试用例，但遇到了问题。我所有的测试用例都扩展了GWTTestCase，并包括以下代码:

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

"ProductPlus.gwt.xml"文件位于我的src/main/java目录下。为了将它包含在我的类路径中，我为我的surefire-plugin配置了这个…

        <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>

然而，在运行"mvn clean test"时，我得到了所有这些错误，包括这个…

这是一个奇怪的错误，因为所讨论的类在我的src/test/java目录中，我已经将其包含为"additionalClassPathElement"(上面)。我还需要做哪些配置来纠正这个错误?——戴夫

测试包必须位于指定模块的客户端类路径中。根据模块的名称，您的测试可能属于com.myco.clearing.product.client包，或者它的子包。
