Question

让我们考虑一下这个基本的ant + pitest例子：https://github.com/hcoles/pitest-ant-example

测试类的类路径定义如下：

<!-- classpath for compiling and testing the code. Note it does not include pitest and it's dependencies -->
<path id="test.path">
        <pathelement location="${classOutputDir}/classes" />
        <pathelement location="${classOutputDir}/test-classes" />
        <pathelement location="lib/junit-4.9.jar" />

</path>

现在，假设我想更改它以过滤掉一些类。例如，我想只包括名称以＆＃34; Partially＆＃34;：

开头的测试类

<path id="test.path">
        <pathelement location="${classOutputDir}/classes" />
        <fileset dir="${classOutputDir}/test-classes">
            <include name="**/Partially*.class" />
            <exclude name="**/ExcludedTest*.class" />
        </fileset>
        <pathelement location="lib/junit-4.9.jar" />

</path>

不幸的是，这个解决方案给了我以下错误：

文件/root/pitest-ant-example/build/test-classes/com/example/PartiallyTestedTest$1.class确实存在。

我做错了什么？如何过滤我想要使用的测试类？

Answer 1

当您从简单的'pathelement'更改为更复杂的'fileset'时，您也会更改classpath的评估时间。

简单的'pathelement'只是告诉ant包含一个目录，但是在定义路径时没有查看该目录。

首次使用路径时，将评估更复杂的文件集。在那一刻，内部类（包含$的内部类）不存在。所以在运行时缺少类。

你必须使用一个技巧，以便在生成内部类之后在正确的时间评估路径。

Answer 2

您无需从类路径中删除内容以选择要运行的测试或要变异的类。 Pitest提供自己的过滤器。

在最近的版本中，这些是

targetClasses
targetTests
excludedClasses
excludedTests

每个人都接受一个globs列表。

此处记录了Ant插件的使用情况http://pitest.org/quickstart/ant/

使用pitest时在ant中过滤类
