My player has an Action in the InputSystem Move, that takes a Vector2 and moves the player based on that input. Straight-forward. I'm using the "Send Messages" behavior on my Player's PlayerInput component.

For the life of me, I can't figure out how to test if OnMove is being called effectively. Here's my most recent attempt, I've tried instantiating the player piecewise from a new game object, loading the player as a prefab, finding the player in the scene, doing any and all of these things in the test and in a setup test function, and I've gotten nowhere.

Test

using System.Collections; using System.Collections.Generic; using System.Linq; using Core; using FluentAssertions; using NUnit.Framework; using UnityEngine; using UnityEngine.InputSystem; using UnityEngine.SceneManagement; using UnityEngine.TestTools;

namespace Tests.PlayMode { public class PlayerTests { public class Physics {...}

    public class Animations {...}

    public class Movement : InputTestFixture {

        [UnityTest]
        public IEnumerator Player_Should_Be_Able_To_Move() {
            SceneManager.LoadScene("TestScene");
            yield return new WaitForSeconds(0.1f);
            
            InputSystem.RegisterLayout<Keyboard>();
            var keyboard = InputSystem.AddDevice<Keyboard>();

            var playerPrefabObject = Resources.Load("Player");
            var playerGameObject = (GameObject)Object.Instantiate(playerPrefabObject);
            var player = playerGameObject.GetComponent<Player>();
            
            yield return new WaitForSeconds(0.5f);
            player.Rigidbody.velocity.x.Should().Be(0);
            
            Press(keyboard.dKey);
            yield return new WaitForSeconds(0.1f);
            Debug.Log(player.MoveDir);
            Debug.Log(player.Rigidbody.velocity);
            player.Rigidbody.velocity.x.Should().BePositive();
            
            Release(keyboard.dKey);
        }
    }
}

}

Player using UnityEngine; using UnityEngine.InputSystem;

namespace Core { public class Player : MonoBehaviour { public Rigidbody2D Rigidbody { get; private set; } public CapsuleCollider2D Collider { get; private set; } public Vector2 MoveDir { get; private set; }

    private void Start() {
        Rigidbody = GetComponent<Rigidbody2D>();
        Collider = GetComponent<CapsuleCollider2D>();
    }

    public void OnMove(InputValue value) {
        Debug.Log("OnMove called");
        MoveDir = value.Get<Vector2>();
        Rigidbody.velocity = MoveDir * 10f;
    }
}
