Test Framework Training

An example solution for the tests are available at the test-solution branch https://github.com/Unity-Technologies/test-framework-training/tree/test-solution

Exercise 1 - Scene content

Write an EditMode test that verifies the content of the ball scene.

• Load the scene.
• Enter into Playmode.
• Verify the ball is there.
• Verify that the ball has the BallControl script assigned to it.

Exercise 2 - Swap materials

Write a test that verifies the functionality of SwapMaterial on the ball control.

• To interact with the ball control, it needs to be assigned to a game object.
• The game object will need a renderer (you can create object using GameObject.CreatePrimitive).
• The SwapMaterial method interacts with an array of Materials on the ball control.
• To create material use new Material(Shader.Find("Specular"));
• In EditMode you can use renderer.sharedMaterial to inspect the current material.

Exercise 3 - Swap materials error

Write a test that verifies the negative scenario of attempted to call swap material, when there are no materials assigned.

• Set up a ball control in the same way as exercise 2, but do not set up the materials.
• You can use LogAssert.Expect to let the test expect the error "No materials available for swapping."
• Consider moving common code for setting up the test object into method with the [Setup] attribute, to share it between the two tests.

Exercise 4 - Applied force

Write two or more playmode tests verifying the behavior of the ball control over time.

• When initializing the ball control, set the Force and SecondsForceApplied values.
• Yield the WaitForSeconds and WaitForFixedUpdate commands to elapse time.
• Evaluate on the transform.position of the ball.
• You can use the UnitySetUpAttribute or SetUpAttribute to create a common setup method.

Exercise 5 - MonoBehaviorTest

Make a MonoBehaviorTest for the ball control that verifies the position after force is no longer applied.

• Create an testable extension of BallControl and let that implement IMonoBehaviourTest. E.g. BallControlTestable
• Use the IsTestFinished to control when the test should stop sending updates on the control.
• In a unity test create a new MonoBehaviourTest<BallControlTestable> and yield that object, once it is set up.
• After yielding the monoBehaviorTest, you can verify the position
• You can use GameObject.Find("MonoBehaviourTest: " + typeof(BallControlTestable).FullName); to find the gameObject that has the ball control.
