Several test methods in the ChessServer module have been refactored for better readability and maintainability. A new method, CreateChallengeForTest, was introduced to reduce redundancy. The use of unnecessary imports in the InMemoryDatabase class has also been tidied up.
The test initialization method within BasicTests.cs has been simplified for improved code readability. Additionally, redundant playerId argument has been removed from RedirectToAction calls within HomeController.cs, streamlining redirection methods.
