如何解决PIT >> INFO : MINION : 3:10:40 pm PIT >> INFO : 发现 0 个测试
我正在尝试将 PIT 测试集成到我的项目中。
这是我的 pom.xml 文件。

我的项目正在使用 Maven,但目前未遵循默认结构。源代码存储在src/com1.com2.com3
,而测试代码存储在test/com1.com2.com3
我运行了 mvn clean instal
l,它运行了我使用 surefire 创建的所有测试文件,但所有这些都导致失败。
然后我继续运行 mvn org.pitest:pitest-maven:mutationCoverage
,它产生以下输出,它传入 2 个类文件,一个是源文件,1 个是类文件。但是,没有检测到任何测试。测试在 JUnit 下运行良好,我会在这里遗漏什么?如果需要更多信息,请告诉我。

解决方法
首先为什么要更改默认值,例如源目录等。遵循约定更容易。所以删除以下内容:
<sourceDirectory>src</sourceDirectory>
<directory>target</directory>
<testSourceDirectory>test</testSourceDirectory>
<testOutputDirectory>target/classes</testOutputDirectory>
并根据 maven 约定更改项目的目录布局。
其次,如果您使用 junit jupiter,则必须至少使用surefire 2.22.2 更好的最新版本(3.0.0-M5)。
此外,您使用的 junit jupiter 5.0.0 已经有大约 3 年的历史了……您应该转到最新版本 (5.7.1) 并且您正在手动定义不应完成的 junit-platform-surefire-provider
不再(长时间)...
您使用的 pitest-maven 版本非常旧(最近的 1.6.4),最后 pitest-junit5-plugin
应定义为 pitest-maven-plugin 的依赖项,同时 0.14 版本已发布。
您可以查看这样的示例项目:https://github.com/khmarbaise/kata-fraction/blob/master/pom.xml
您还混合了不同的概念:
maven-compiler-plugin 的配置:
<configuration>
<source>11</source>
<target>11</target>
</configuration>
和基于属性的方法:
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<myTestSourceDirectory>test</myTestSourceDirectory>
</properties>
那么最后一个问题是:JDK 8 还是 JDK11?
如果您使用 JDK11,您应该只设置这些选项,而不是同时设置两个选项,然后您可以检查使用 --release 11
via (<maven.compiler.release>11</maven.compiler.release>
property based)..
终于看到你有依赖了:
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
这是否意味着您正在使用基于 JUnit 4 的单元测试?如果是这样,您必须添加 junit-vintage-engine,以便您可以通过 JUnit Jupiter 运行基于 JUnit 4 的测试。 我强烈建议将所有基于 JUnit 4 的测试迁移到 JUnit Jupiter,然后移除对 junit 4 的依赖。
,我们有非常详细的文档。它包含示例以及指向我们在 GitHub 上的集成测试的链接。请在您的浏览器 https://maven.apache.org/surefire/maven-surefire-plugin/examples/junit-platform.html 中打开此链接,如果有不清楚的地方,请随时提出问题。我们很乐意回答这些问题。
