ArgumentOutOfRangeException thrown when defining device in [OneTimeSetUp] and using [OneTimeTearDown] to remove it

Won't Fix

When using the InputTestFixture you need to use [SetUp] and [TearDown]. [OneTimeSetup] & [OneTimeTeardown] have different timing and won't work well with the InputTestFixture's lifecycle. This is due to how the InputTestFixture mocks user input data and it's load / restore mechanism. Old data was restored in your repo project's case causing issues. We have added documentation around this for an upcoming release to avoid confusion. Here is also a minimal working test for this case that had the same scene setup used in the repo project. Copying this Setup / Teardown code should fix the issue for you. Swapping between [OneTimeSetup] & [OneTimeTearDown] vs [SetUp] & [TearDown] with the same code should also reproduce / fix the error without the need for the workaround you provided also. using System.Collections; using NUnit.Framework; using UnityEditor.SceneManagement; using UnityEngine.InputSystem; using UnityEngine.SceneManagement; using UnityEngine.TestTools; namespace Tests.InputSystem { public class SceneLoadingTests : InputTestFixture { private const string TestScenePath = "Assets/Tests/InputSystem/Assets/AutoSwitchBoolTestScene.unity"; private Scene m_Scene; [SetUp] public void SetUpTest() { m_Scene = EditorSceneManager.LoadSceneInPlayMode(TestScenePath, new LoadSceneParameters(LoadSceneMode.Additive)); } [TearDown] public void TearDown() { SceneManager.UnloadScene(m_Scene); } [UnityTest] [Category("SceneLoading")] public IEnumerator Users_CanLoadASceneWithPlayerInputAutoSwitchFlagSetToTrue_InTestsWithInputTestFixture() { yield return null; } } }
