如何阻止 maven 运行测试两次?

我有一个大项目,大约有5000个测试用例。运行时,它将运行目标两次(一次作为安装的一部分,第二次作为插件的一部分)。mvn clean installtestsurefire

为什么它需要第二次运行 ?还有没有办法强制使用目标结果,而不是重新调用它自己的结果?我认为这是浪费时间和机器资源,特别是最近第二轮运行导致了构建错误,无论我向maven流道泵入多少堆,它仍然会在第二轮测试中死亡。testsurefiretesttestPermGen

这是我的肯定的插头配置:

 <plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.18.1</version>
    <executions>
       <execution>
         <id>default-test</id>
         <phase>test</phase>
         <goals>
             <goal>test</goal>
         </goals>
         <configuration>
            <parallel>classes</parallel>
            <threadCount>3</threadCount>
         </configuration>
      </execution>
   </executions>
</plugin>

有没有办法调整插件以更好地处理机器资源?

答案 1

我认为在你的原因第二次测试运行。Maven将其视为除了测试阶段的默认目标之外要执行的另一个目标。<execution>pom.xml

由于是 Maven 中默认用于测试阶段的插件,因此您只需在 .修改您的如下maven-surefire-plugin<configuration><execution>pom.xml

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.18.1</version>
    <configuration>
        <parallel>classes</parallel>
        <threadCount>3</threadCount>
    </configuration>
  </plugin>
</plugins>

答案 2

如果你的pom中cobertura和surefire插件都有,测试将执行两次。为了避免在cobertura插件中添加执行阶段,如下所示:

<plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>cobertura-maven-plugin</artifactId>
            <executions>
                <execution>
                    <phase>none</phase>
                </execution>
            </executions>
</plugin>
