单元测试在执行mvn安装时执行两次

Question

单元测试将被执行两次。

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，但随后在控制台中不会生成覆盖率。

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，我在控制台中获得了覆盖范围，但是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，以便获得覆盖率，但只需要运行一次测试用例。让测试用例也只执行一次的方法是什么？

Answer 1

你需要做两件事：

1. 在‘scoverage maven-plugin’插件的‘配置’部分添加下面一行。

skipTests=false

1. 在根pom.xml中设置以下属性
