# 4\. Reach Wand Test
|
||
|
|
|
||
|
|
## Learning Objectives
|
||
|
|
|
||
|
|
Perform Assertions on your character position and behavior.
|
||
|
|
|
||
|
|
## 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.
|
||
|
|
|
||
|
