PIT覆盖生成minion异常退出

Question

在 build.gradle 中添加所有必需的配置后，在我的项目中运行 Pitest gradle 任务时，我看到以下堆栈跟踪。你能帮我解决这个问题吗？我使用的是 1.5.1 版本的插件。

已按照 https://github.com/szpak/gradle-pitest-plugin

中的说明在 build.gradle 中完成更改

Answer 1

根据错误消息，您没有启用 Pitest junit 5 插件。

如果你添加

junit5PluginVersion = '0.12'

对于配置，插件将被启用并且测试应该被选择。

Answer 2

问题是最新版本的 PIT 使用的是 JUnit5，而我使用的是 JUnit4。所以，我通过迁移到 JUnit5 解决了这个问题

如果您使用的是 Maven，请将以下行添加到您的 pom 文件中：

  <properties>
    <junit.jupiter.version>5.8.1</junit.jupiter.version>
    <junit.platform.version>1.8.1</junit.platform.version>
  </properties>
  
  <dependencies>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-engine</artifactId>
        <version>${junit.jupiter.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-api</artifactId>
        <version>${junit.jupiter.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-params</artifactId>
        <version>${junit.jupiter.version}</version>
        <scope>test</scope>

        <artifactId>junit-platform-suite</artifactId>
        <version>${junit.platform.version}</version>
        <scope>test</scope>
    </dependency>

</dependencies>

Answer 3

这是因为我们没有提供正确版本的 junit5PluginVersion 在KTS中我们需要给出这样的配置

    // Configure the PitestPluginExtension
configure<PitestPluginExtension> {
    // Set the JUnit 5 plugin version
    junit5PluginVersion.set("1.2.0")

    // Avoid calls to the specified classes
    avoidCallsTo.set(setOf("kotlin.jvm.internal"))

    // Set the mutators to be used
    mutators.set(setOf("STRONGER"))

    // Specify the target classes for mutation testing
    targetClasses.set(setOf("com.arcesium.treasury.margin.web.service.*"))

    // Specify the test classes for mutation testing
    targetTests.set(setOf("com.arcesium.treasury.margin.web.service.*"))

    // Set the number of threads for mutation testing
    threads.set(Runtime.getRuntime().availableProcessors())

    // Set the output formats for the mutation testing report
    outputFormats.set(setOf("XML", "HTML"))

    // Set the mutation threshold
    mutationThreshold.set(0)

    // Set the coverage threshold
    coverageThreshold.set(0)
}

// Make the 'check' task depend on the 'pitest' task
tasks.named("check") {
    dependsOn(":pitest")
}

Answer 4

确保您没有任何 jqwik 依赖项。由于某种原因，这与最糟糕的配置混淆了。
