我的 PITEST 不会运行。覆盖生成minion异常退出。我需要帮助才能正确配置我的 pom.xml

Question

运行mvn org.pitest:pitest-maven:mutationCoverage 时，我收到如下错误（ Environment: Windows 10, Maven 3.6.1, Java 11, junit-jupiter 5.4.1, pitest 1.4.7)

Answer 1

为了增加我的两分钱，我使用了 JUnit 5 和文档中的插件。但是，我对 junit-jupiter-api 有一个 JUnit 依赖项，我应该一直使用 junit-jupiter-engine。

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.7.2</version>
    <scope>test</scope>
</dependency>

我的设置是这样的：

Answer 3

在我的情况下，我收到了这个错误，因为 pom 中包含了 junit 复古引擎，并且没有找到使用 Junit 4 的测试，所以我只是从 spring-boot 中排除了 junit-vintage。我还排除了 junit 和 mockito 核心，因为我手动设置了具有固定版本的依赖项。

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.mockito</groupId>
                <artifactId>mockito-core</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.junit.vintage</groupId>
                <artifactId>junit-vintage-engine</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

Answer 4

我通过跟随先生修复了 JUnit 5 和“minion 异常退出”问题。 Mkyong 例子here.

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

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

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

Answer 5

依赖项中似乎缺少 JUnit，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>
