Prefereed test reporting framework

I’m writing a small java, TestNG based automation framework, where I need to combine 2 separate tests from the same class to construct a result. Example :

public class TestX {
    @Key1
     @Test
     public testX1() {
     }

     @Key2(pair=“testX1")
     @Test
     public testX2() {
     }
}

Key1 and Key2 are custom annotations. My test results need to combine test1 and test2 to show as 1 result based on custom annotations. Also, I would like to implement better test result framework (hoping for a better look and feel & customisable options). I’m looking at Allure as of now.

Have any one of you tried doing anything similar? Any pointer regarding where or what I should look at ? Any other test reporting framework I should look at ?
