PITest跳过ant中的测试

Question

我有一个问题，就是PITest跳过了我的一些测试。它没有报告被测试的类的行覆盖和所有的突变保持活着：

用Collections.emptyList代替了.→NO_COVERAGE的返回值

下面的列表是空的：

试验检查

我确实检查了以下几点：

类和测试的类文件被支持在类路径verbose=true

• I的

• 中的一个目录中，测试不排除

• 测试，在同一个目录下运行

• 源目录是正确的，

H 113控制台上没有出现错误，即使在用

• 日志记录和检查所有参数H 216F 217>时

<pitest
                pitClasspath="pit.path"
                classPath="mutation.path"
                targetClasses="my.package1.*,my.package2.*,my.package3.*"
                targetTests="my.package1.Class1Test,my.package2.sub.Class2Test,my.package3.sub.Class3Test"
                reportDir="pitest"
                sourceDir="src,testsrc"
                timestampedReports="false"
                outputFormats="HTML,XML"
                excludedClasses="my.package1.*Test,my.package2.*Test,my.package3.*Test"
                verbose="true"
        />

我使用的是PITest版本1.4.11，但我也用1.6.2和1.4.3进行了测试。另外，我还使用了Java 1.8.0_211和ant1.9.13。

我在：https://github.com/johannesn/pittestskippingtests建立了一个测试项目

这是此示例项目的日志输出：

经过大量的调试和尝试之后，我发现没有找到测试方法，因为缺少junit依赖的hamcrest。

对于遇到类似问题的其他人，请尝试调试以下方法：

org.pitest.junit.RunnerSuiteFinder#apply

取决于您的测试设置(例如，如果您使用junit )可能是一个不同的子类

org.pitest.testapi.TestSuiteFinder

我经历了以下例外：

异常是runner变量的一部分。使用以下方法打印：

((ErrorReportingRunner) runner).causes.get(0).printStackTrace()
