junit - 使用 Maven 从 @Category 运行所有测试

Question

我只想运行我的单元测试的一个子集，那些由特定的 @Category 定义的。 .

所以我读了几个SO问题，例如this one (这正是我正在寻找的)，还有 this one .

我的问题的解决方案似乎由 ClasspathSuite project 提供.于是我开始写NewTest和 OldTest将定义我的测试类别的接口(interface)。然后，我创建了 AllTests套房:

@RunWith(ClasspathSuite.class)
public class AllTests { }

之后，我创建了一个 AllNewTests套房:

@RunWith(Categories.class)
@IncludeCategory(NewTest.class)
@SuiteClasses( { AllTests.class })
public class AllNewTests { }

最后，我创建了两个 JUnit 类，每个类别一个:

@Category(NewTest.class)
public class SomeNewTests {
    // some tests...
}

@Category(OldTest.class)
public class SomeOldTests {
    // some tests...
}

现在，如果我运行 全部测试 , Eclipse 启动我项目的所有测试，而 Maven 失败，因为没有找到测试:

mvn test -Dtest=AllTests

...
-------------------------------------------------------
 T E S T S
-------------------------------------------------------
Running my.company.AllTests
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.093 sec
There are no tests to run.

如果我运行 AllNewTests (这是正确的做法，对吗？)，在 Eclipse 中一切都很好(即它只运行带有 @Category(NewTest.class) 注释的测试)但是 Maven 返回错误 :

mvn test -Dtest=AllNewTests

...
-------------------------------------------------------
 T E S T S
-------------------------------------------------------
Running my.company.AllNewTests
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.125 sec <<< FAILURE!

Results :

Tests in error:
  initializationError(my.company.AllNewTests)

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0

[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE

我的问题是我做错了什么？

技术细节:Java 6、Maven 3.0.2、JUnit 4.8.1、Surefire 插件 2.7.1、cpsuite-1.2.5

Answer 1

作为更新:从 Surefire 插件 v2.11 开始，现在支持 JUnit 4.8+ 样式类别。

release notes for Surefire v2.11提到新功能。可以使用 groups 配置 surefire:test 目标。 .
