Question

TestNG 6.8.8, Ubuntu 16.04 LTS, Apache Maven 3.3.9

我有以下TestCase和TestSuite：

public class TestCase implements ITest{
    private final int i;

    public TestCase(int i) {
        this.i = i;
    }

    public String getTestName() {
        return "name";
    }

    @Test
    public void test(){
        System.out.println(i);
    }
}

public class MyTestSuite {

    @Factory
    public Object[] testCases(){
        return new Object[]{ new TestCase(1), new TestCase(2) };
    }

}

当我尝试在cmd中运行mvn test时，我遇到以下异常：

Running com.test.b.TestCase

但是在将MyTestSuite重命名为TestSuiteSomeSuffix后，mvn test执行得很好。我试图将其重命名为TestSomeSuffix，但它也能正常工作。

但TesSomeSuffix会发出我在上面发布的例外情况。这是什么？为什么它取决于命名？这个例外有一个非常奇怪的消息BTW。

来自the surefire documentation：

默认包含

<includes>
   <include>**/Test*.java</include>
   <include>**/*Test.java</include>
   <include>**/*TestCase.java</include>
</includes>

这解释了为什么您看到TestCase / TestSuiteSomeSuffix / TestSomeSuffix和MyTestSuite之间存在一些差异。

在您的示例中，您不希望将TestCase包含在surefire中，而只包含MyTestSuite。

我看到两个选项：

根据默认的surefire配置重命名文件，或
配置surefire。

测试工厂在使用前缀命名时抛出NPE
