Jacoco 覆盖率专家

Question

运行 mvn test 时，我的 spring boot 应用程序构建成功。当我执行 mvn clean install 或 mvn clean verify 时，构建失败。这是因为我将最小代码覆盖率配置为 80%。当我运行 mvn clean install/verify 时，结果显示 指令覆盖率是 0.00，但预期最小值是 0.50。

在设置最小阈值之前，运行 mvn clean install 会得到以下结果，即覆盖率为 65%。我的配置中缺少什么？我错过了什么吗？我怎样才能让 jacoco 选择正确的代码？

这是我的pom

在你的插件配置中需要这样设置；

在你的例子中，标签插件来自插件标签。

如果您将 Jacoco 与 PowerMockito 一起使用，并且您想要覆盖的课程在 PrepareForTest 中进行，那么在这种情况下，它将显示 0% 的覆盖率。 尝试从 PrepareForTest 中删除目标类
