使用Java和Maven在编译时生成类

Question

I have a project that have one junit test class, i need to generate multiple junit classes in compile time, what exactly i want to do is have the same junit class but with a change in a property value.

I could not accomplish this in runtime, this shold be done in compile time.

I tried to see the aspectj but could not find how to generate classes in compile time.

is that even possible in java ??

You can use @Parameterized as stated by Andy, or inherit from a base Test class :

abstract class CommonTests {
    @Test
    public void testA() { 
        assertEquals(1, getValue()); 
        ...
    }

    @Test
    public void testB() { ...}
    ....
    abstract int getValue();
}

class Test1 extends CommonTests {
   int getValue() { return 1;}
}

class Test2 extends CommonTests {
   int getValue() { return 2;}
}
