我如何运行一个 pitest ant 脚本

Question

我正在尝试为运行 pitest 创建一个 ant 脚本，以便能够自动化我的变异测试。我收到错误：

Could not find or load main class org.pitest.mutationtest.commandline.MutationCoverageReport

这是我的 MutationTest.xml ant 脚本

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<project basedir="." default="mutationCoverage" name="PhoneBook">
    <property name="ECLIPSE_HOME" value="C:/Program Files/eclipse/"/>
    <path id="JUnit 4.libraryclasspath">
        <pathelement location="${ECLIPSE_HOME}plugins/org.junit_4.11.0.v201303080030/junit.jar"/>
        <pathelement location="${ECLIPSE_HOME}plugins/org.hamcrest.core_1.3.0.v201303031735.jar"/>
    </path>
    <path id="PhoneBook.classpath">
        <pathelement location="bin"/>
        <path refid="JUnit 4.libraryclasspath"/>
    </path>
    <path id="pit.path">
        <pathelement location="lib/pitest-1.1.4.jar" />
        <pathelement location="lib/pitest-ant-1.1.4.jar" />
    </path>

    <taskdef name="pitest" classname="org.pitest.ant.PitestTask" classpathref="pit.path" />

    <target name="mutationCoverage">
        <pitest
            pitClasspath="PhoneBook.path"
            classPath="PhoneBook.path"
            targetClasses="pbook.*"
            targetTests="pbook.*"
            reportDir="MutationReports"
            sourceDir="src"/>
    </target>
</project>

是什么导致了这个错误，我该如何解决？

编辑：我将 pitClasspath="PhoneBook.path" 更改为 pitClasspath="pit.path"，现在出现新错误：

我不知道这是好是坏，但希望它能帮助您找到问题。

Answer 1

提供了 pitest ant 构建的工作示例

https://github.com/hcoles/pitest-ant-example

我建议您从这里开始并对其进行编辑，直到您的代码库构建工作正常。

我能看到的一个区别是您没有在最糟糕的路径中包含 junit。

您的构建看起来有点奇怪，因为它似乎与 eclipse 相关联。如果您来自 IDE 运行为什么不使用 eclipse 插件？

此外，如果您不依赖 Ant，您可能需要考虑将 maven 作为替代方案。

Answer 2

我相信您的大部分问题是您正在尝试使用 Eclipse 生成的 build.xml 文件，该文件不包含变异测试目标，以及您为解决此问题而添加的目标有一些错误。

我建议从项目 here 开始，尝试了解它的工作原理，然后更改其 build.xml 文件以满足您的需要。但是，如果这不起作用，从您的 other question 判断，以下 build.xml 应该起作用，如果：

您将文件分为两个源目录 "src" 和 "test"
src 和 test 文件夹都包含包 "pbook"
您将测试的名称更改为以 "Test" 结尾，而不是以

<?xml version="1.0" encoding="UTF-8"?>
