JUnitParams for each method of class

Is it possible to run parameterized test for each method of test class with JUnitParams and class level annotations? Something like:

@RunWith(JUnitParamsRunner.class)
@Parameters(method = "paramsGenerator")
public class TestMethod {

    public Integer[] paramsGenerator() {
        return new Integer[] {1, 2, 3};
    }

    @Test
    public void test1(Integer myInt) {
        ......
    }

    @Test
    public void test2(Integer myInt) {
        ......
    }
}

No, you cannot have a class-level parameters annotation that would cover all test methods. You must declare @Parameters(method = "paramsGenerator") on each test method. Your use case is pretty rare - most often different test methods require different parameters (eg. you have one method for valid and one for invalid input).
