我的 PITEST 无法运行。覆盖生成minion异常退出。我需要帮助来正确配置我的 pom.xml

Question

运行时mvn org.pitest:pitest-maven:mutationCoverage出现如下错误（ Environment: Windows 10, Maven 3.6.1, Java 11, junit-jupiter 5.4.1, pitest 1.4.7）

我按照 Mkyong 先生在Maven \xe2\x80\x93 PITest 突变测试示例中的示例修复了 JUnit 5 和“minion 异常退出”问题。

\n

向下滚动到 pom.xml 部分，在 pom 文件的构建部分中定义了一个偷偷摸摸的 Pitest-junit5-plugin 依赖项：

\n

<dependencies>\n    <dependency>\n        <groupId>org.pitest</groupId>\n        <artifactId>pitest-junit5-plugin</artifactId>\n        <version>0.8</version>\n    </dependency>\n</dependencies>\n

\n

这是我在 Maven 测试阶段用于 jacoco 代码覆盖率和坑突变的工作 pom.xml。如果您只对坑部分感兴趣，请随意从构建标签中删除整个 jacoco 插件部分。

Answer 2

JUnit 似乎缺少依赖项，因此请尝试将以下内容添加到pom.xml：

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>
