Testing a parent and child issues.

[Tatyana]

Hello Everyone,

The question is about testing for a parent epic and subtasks (features).

Given:
One epic with 6 subtasks .
Each subtask is developed and considered to be done separately. The whole epic is delivered (done) only all the subtasks are done. The DoD  -  all tests are positive, unhappy path testing failed for each subtask.

The problem :

Epic testing.

The epic meant to be delivered only when all six subtasks ( features) delivered without failing -  which brings the number of all  possible testing scenarios when more than one issue is resolved and the others are not ( in different combinations) coming to 126.

Question  - is this  the right approach to create issues ( a parent epic and subtasks) and conduct testing ( testing unhappy paths are mandatory)?

My question might be duplicating a question raised earlier:

@Tatyana Welcome! Epics are the top issue type, you might use epics to identify the "abstract" feature, that epic will be divided on several US and each US might 1 to many subtasks (or child issues).
