In an upcoming change, I stumbled upon a test failure mode wherein tests in `TestSceneScreenNavigation` would die on the following exception: 2023-05-07 17:58:42 [error]: System.ObjectDisposedException: Cannot access a closed Realm. 2023-05-07 17:58:42 [error]: Object name: 'Realms.Realm'. 2023-05-07 17:58:42 [error]: at Realms.Realm.ThrowIfDisposed() 2023-05-07 17:58:42 [error]: at Realms.Realm.All[T]() 2023-05-07 17:58:42 [error]: at osu.Game.Beatmaps.BeatmapManager.<>c__DisplayClass25_0.<QueryBeatmap>b__0(Realm r) in D:\a\osu\osu\osu.Game\Beatmaps\BeatmapManager.cs:line 282 2023-05-07 17:58:42 [error]: at osu.Game.Database.RealmAccess.Run[T](Func`2 action) in D:\a\osu\osu\osu.Game\Database\RealmAccess.cs:line 387 2023-05-07 17:58:42 [error]: at osu.Game.Beatmaps.BeatmapManager.QueryBeatmap(Expression`1 query) in D:\a\osu\osu\osu.Game\Beatmaps\BeatmapManager.cs:line 282 2023-05-07 17:58:42 [error]: at osu.Game.Tests.Visual.OnlinePlay.TestRoomRequestsHandler.<HandleRequest>g__createResponseBeatmaps|6_0(Int32[] beatmapIds, <>c__DisplayClass6_0& ) in D:\a\osu\osu\osu.Game\Tests\Visual\OnlinePlay\TestRoomRequestsHandler.cs:line 174 2023-05-07 17:58:42 [error]: at osu.Game.Tests.Visual.OnlinePlay.TestRoomRequestsHandler.HandleRequest(APIRequest request, APIUser localUser, BeatmapManager beatmapManager) in D:\a\osu\osu\osu.Game\Tests\Visual\OnlinePlay\TestRoomRequestsHandler.cs:line 140 2023-05-07 17:58:42 [error]: at osu.Game.Tests.Visual.TestMultiplayerComponents.<>c__DisplayClass18_0.<load>b__0(APIRequest request) in D:\a\osu\osu\osu.Game.Tests\Visual\TestMultiplayerComponents.cs:line 80 2023-05-07 17:58:42 [error]: at osu.Game.Online.API.DummyAPIAccess.<>c__DisplayClass32_0.<Queue>b__0() in D:\a\osu\osu\osu.Game\Online\API\DummyAPIAccess.cs:line 74 Upon closer inspection, one of the tests in the scene instantiates a `TestMultiplayerComponents` instance. `TestMultiplayerComponents` registers a custom request handler onto `DummyAPIAccess`. Normally, this is not an issue; however, because `TestSceneScreenNavigation` is an `OsuGameTestScene`, and therefore has its storage recycled after every test, this leads to the error above in the following scenario: 1. `TestPushMatchSubScreenAndPressBackButtonImmediately()` passes. 2. The test is cleaned up, and the test case's storage is recycled, including the test case's realm database. 3. In a subsequent test, a web request handled by the dummy API request handler is fired. The dummy API request handler subsequently attempts to access a realm that does not exist anymore. As the usage of `TestMultiplayerComponents` is highly unorthodox in this particular case, I'm opting for a localised fix which ensures that the request handler is cleaned up appropriately. |
