执行 mvn install 时单元测试执行两次

Question

单元测试执行了两次。

当我从 pom 中的 maven 插件中删除目标报告和阶段准备包时，测试会执行一次，但随后不会在控制台中生成覆盖率。

但是当我在 pom 中添加来自 maven 插件的目标报告和阶段准备包时，我在控制台中得到了覆盖，但单元测试被执行了两次。

我需要在我的 pom 中有目标报告和阶段准备包才能获得覆盖，但只需要运行一次测试用例。什么是让测试用例只执行一次覆盖的方法。

Answer 1

你需要做两件事：

1. 在 'scoverage-maven-plugin' 插件的 'configuration' 部分添加以下行。

   <additionalForkedProjectProperties>skipTests=false</additionalForkedProjectProperties>
   

2. 在你的根 pom.xml 中设置以下属性

   <properties>
        <!--  Add other properties here... -->
   
        <!--  skipTests is set to 'true' here to avoid duplicate runs of all test cases. It's set to false in scoverage-maven-plugin below. -->
        <skipTests>true</skipTests>
    </properties>
