4. Reach Wand Test

Learning Objectives

Exercise

1. Go back to the previous

   MovementTest.cs

   file.
2. Write a

   MainScene\_CharacterReachesWand

   test that makes your character move right, and checks if it reaches the wand location.

Hints

• Look for Altar and Sara Variant game objects in your scene. You are interested in measuring the X position of your Transform objects.
• Wand location X position is equal float of 21.080. Main Character X position is dynamic and it changes whenever it moves.
• Consider setting a timeout that makes the test fail if the Wand is not reached.

Solution

using System.Collections;using NUnit.Framework;using UnityEngine;using UnityEngine.TestTools;using UnityEngine.SceneManagement;public class MovementTest{    private Transform _characterTransform;    private float _testTimeout = 25.0f;    private float _wandLocation = 21.080f;    [UnityTest]    public IEnumerator MainScene_CharacterReachesWand()    {      SceneManager.LoadScene("Assets/Scenes/Main.unity", LoadSceneMode.Single);      yield return waitForSceneLoad();      var elapsedTime = 0.0f;      yield return GoRight();      while (GetCurrentCharacterPosition() <= _wandLocation)      {          yield return null;          elapsedTime += Time.deltaTime;          if (elapsedTime > _testTimeout)          {            Assert.Fail($"Character did not reach location position in {_testTimeout} seconds.");          }      }    }    private float GetCurrentCharacterPosition()    {      // Get Main character's Transform which is used to manipulate position.      if (_characterTransform == null)      {          _characterTransform = GameObject.Find("Sara Variant").transform;      }      return _characterTransform.position.x;    }    private IEnumerator GoRight()    {      TestInputControl.MoveLeft = false;      yield return null;      TestInputControl.MoveRight = true;    }    private IEnumerator waitForSceneLoad()    {        while (SceneManager.GetActiveScene().buildIndex > 0)        {            yield return null;        }    }}
