Question

我试图创建一个运行pitest的ant脚本，以便能够自动进行突变测试。我收到了错误：

无法找到或加载主类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>

导致此错误的原因是什么，我该如何解决？

修改：我将pitClasspath="PhoneBook.path"更改为pitClasspath="pit.path"，现在我遇到了新的错误：

我不知道这是好还是坏，但希望它有助于找到问题。

Answer 1

提供了一个pitest ant构建的工作示例

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

我建议你从这开始编辑它，直到你的代码库有一个有效的构建。

我可以看到的一个区别是你没有将junit包括在最陡峭的道路上。

你的构建看起来有点奇怪，因为它似乎与eclipse有关。如果您从IDE运行，为什么不使用eclipse插件？

此外，如果您不依赖于Ant，您可能需要将maven视为替代方案。

Answer 2

我相信你的很多问题是你正在尝试使用Eclipse生成的build.xml文件，该文件不包含变异测试目标，而你为补救这个目标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build.xml文件以满足您的需求。但是，如果这不起作用，从other question判断，以下build.xml应该在以下情况下起作用：

您将文件分成两个源目录“src”和“test”
src和test文件夹都包含“pbook”包
您将测试的名称更改为以“测试”结尾而不是从中开始
