Maven运行JUnit测试

Question

我在使用Maven项目编译和运行JUnit测试时遇到问题。

在pom.xml中，我添加了以下几行以配置surfire插件：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.16</version>
    <configuration>
        <encoding>UTF-8</encoding>                    
        <skipTests>false</skipTests>                                 
        <includes>
            <include>**/*.java</include>
        </includes>
    </configuration>

    <executions>
        <execution>
            <id>unit-test</id>
            <phase>test</phase>
            <goals>
                <goal>test</goal>
            </goals>
            <configuration>
                <skip>false</skip>
                <includes>
                    <include>**/Client*.java</include>
                </includes>   
            </configuration>
        </execution>
    </executions>
</plugin>

测试类位于路径“ src / test / java //”下。

当我运行命令mvn test我得到以下输出：

[INFO] Storing buildScmBranch: trunk
[INFO] [resources:resources {execution: default-resources}]
[INFO] Using 'UTF-8' encoding to copy filtered resources.
[INFO] Copying 10 resources
[INFO] [cxf-codegen:wsdl2java {execution: generate-sources}]
[INFO] [compiler:compile {execution: default-compile}]
[INFO] Nothing to compile - all classes are up to date
[INFO] [resources:testResources {execution: default-testResources}]
[INFO] Not copying test resources
[INFO] [compiler:testCompile {execution: default-testCompile}]

[INFO] [surefire:test {execution: default-test}]
[INFO] Tests are skipped.
[INFO] [surefire:test {execution: unit-test}]
[INFO] No tests to run.
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] No tests were executed!  (Set -DfailIfNoTests=false to ignore this error.)

我真的不知道哪里错了。

编辑：我更改pom配置，如下所示，因为我还注意到还没有编译测试类：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.0.2</version>
    <configuration>
        <source>1.6</source>
        <target>1.6</target>
    </configuration>
    <executions>
        <execution>
            <id>default-testCompile</id>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
                <skip>false</skip>
                <additionalClasspathElements>
                    <additionalClasspathElement>${basedir}/target/*.jar</additionalClasspathElement>
                </additionalClasspathElements>
                <directory>${basedir}/src/test/java</directory>
                <includes>
                    <include>**/*.*</include>
                </includes> 
            </configuration>
        </execution>
    </executions>
</plugin>

这样，即使我因为使用​​cxf-codegen-plugin生成了代码而无法编译它们，maven仍开始考虑我的测试源并尝试对其进行编译，但该测试编译似乎看不到它。

Answer 1

该错误意味着没有测试用例匹配**/Client*.java 。

确保图案正确。 同样， mvn -X （启用调试输出）可能会提示您Maven为什么找不到任何测试。

Answer 2

如果您遵循Maven的默认结构（src / main / java中的代码，src / test / java中的测试），则pom.xml中不需要任何特定配置（测试目标内置于Maven中）。

尝试删除特定的surefire配置并开始运行：

mvn test

Answer 3

可能是此处或此处所述的Maven surefire插件缺陷。
