Display names of nested parameterized constructs

[sormuras]

In case of nested parameterized constructs it is sometimes beneficial to have all "display names merged" at the leaf level. For example, starting a with a top-level @ParameterizedClass nesting a @ParameterizedTest method:

@ParameterizedClass @ValueSource(strings = {"a", "b"}) record HelloParams(String string) { @ParameterizedTest @ValueSource(ints = {1, 2}) void test(int number) {} }

yields

╷ └─ JUnit Jupiter ✔ └─ HelloParams ✔ ├─ [1] string = "a" ✔ │ └─ test(int) ✔ │ ├─ [1] 1 ✔ │ └─ [2] 2 ✔ └─ [2] string = "b" ✔ └─ test(int) ✔ ├─ [1] 1 ✔ └─ [2] 2 ✔ 

At the moment, there's no way to customize the names of the 4 generated names for each @ParameterizedTest to include their parents display name. For example, to make last line:

└─ [2] 2 ✔

read

└─ HelloParams [string="b"] :: test(int) :: [2] 2

Including all arguments injected for that test.
