Tests fail when running multiple at the same time

[Mizkei1]

Hi, I have very basic setup for testing if the player can jump. The issue with this is that if I run the "PlayerCanJump" alone, it will pass just fine, but if I run the whole TestSuite tests, then it will fail. Is there some clean up that is needed to be done after the tests when using SceneRunner, or in general? Also to mention, if I comment out the "SetupWorks" test and run all the TestSuites (2 in total), the "PlayerCanJump" test will also fail in that case. Any idea what could be causing this or is this just a fault in my game's code or smth?

[TestSuite]
    public class PlayerJumpTests
    {
        ISceneRunner runner;
        Node2D player;

        [BeforeTest]
        public void RunBeforeTests()
        {
            runner = ISceneRunner.Load("res://TestScenes/PlayerControlTestScene.tscn");
            player = runner.FindChild("Player") as Node2D;
            runner.MaximizeView();
        }

        [TestCase]
        public void SetupWorks()
        {
            Assertions.AssertString(player.Name).IsEqual("Player");
        }

        [TestCase]
        public async Task PlayerCanJump()
        {
            var position = player.Position;
            runner.SimulateKeyPressed(Key.Space);
            await runner.AwaitIdleFrame();
            runner.SimulateKeyPressed(Key.Space);
            await runner.SimulateFrames(20);
            Assertions.AssertFloat(position.Y).IsGreater(player.Position.Y);
        }
    }

Hi, sorry for the late answer.
It looks good from test setup, the scene is loaded for every test case and should have the initial state.

To say more about this, I need an example to reproduce.
