使用Maven从@Category运行所有测试

Question

我想只运行我的单元测试的一个子集,由特定的测试定义@Category.

所以我读了几个SO问题,比如这个(这正是我要找的),还有这个问题.

我的问题的解决方案似乎是由ClasspathSuite项目提供的.所以我开始编写定义我的测试类别的接口NewTest和OldTest接口.然后,我创建了AllTests套件:

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

之后,我创建了一个AllNewTests套件:

@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AllTests,Eclipse会启动我项目的所有测试,而Maven会因为没有找到测试而失败:

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(这是正确的事情,对吧？),在Eclipse中一切都很好(即它只运行带有的测试@Category(NewTest.class))但是Maven返回一个错误:

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.

Surefire v2.11的发行说明提到了新功能.可靠性:测试目标可以使用组进行配置.
