Scenario 1: Returns success message and persists forum with typical valid inputs

Details:
  TestName: returnsSuccessMessageAndPersistsForumWhenValidInput
  Description: Validates that when provided with a non-empty name, a non-empty description, and a positive userId, the method constructs a forum entry, persists it via ForumIndexRepository.save, and returns the fixed success message.

Execution:
  Arrange: Set up a ForumController instance with ForumIndexRepository mocked to accept any ForumIndexModel; ensure LogRepository and ForumChatRepository are also mocked. Prepare inputs such as nameForum = "General", forumDescription = "General discussion", userId = 42.
  Act: Invoke createForumIndex with the arranged inputs.
  Assert:
    - Assert that the returned value equals the exact string "Forum criado".
    - Verify that ForumIndexRepository.save is called exactly once with any ForumIndexModel instance.
    - Verify that there are no interactions with LogRepository and ForumChatRepository.

Validation:
  Confirms that the method’s primary behavior is to save a newly constructed forum and return a static success message. Ensures there are no side effects on unrelated components and that the method’s output is stable and predictable for valid input.
