How to refactor UnityTests - seperating methods with yield

Hello

I wonder how to seperate methods which return IEnumerator with yield. For example I have the following nearly identical tests (it doens't matter if the tests make sense):

Code (CSharp):

1. [UnityTest]
2. public IEnumerator WaitFor1Second()
3. {
4.      float startTime = Time.time;
5.      yield return new WaitForSeconds(1f);
6.      Assert.AreEqual(1f, Time.time - startTime, 0.1f);
7. }
8.  
9. [UnityTest]
10. public IEnumerator WaitFor2Seconds()
11. {
12.      float startTime = Time.time;
13.      yield return new WaitForSeconds(2f);
14.      Assert.AreEqual(2f, Time.time - startTime, 0.1f);
15. }

How can I split those tests up? At the end it should look like this:

Code (CSharp):

1. [UnityTest]
2. public IEnumerator WaitFor1Second()
3. {
4.      yield return WaitSecondsTest(1f);
5. }
6.  
7. [UnityTest]
8. public IEnumerator WaitFor2Seconds()
9. {
10.      yield return WaitSecondsTest(2f);
11. }

Thanks and have a great day!

 

Last time I checked for UnityTest you can only yield null, you can't yield any IEnumerators or new WaitForSeconds(f). You'd probably need to do something alone the lines of:

Untested.

Code (CSharp):

1.         [UnityTest]
2.         public IEnumerator TimerShouldSucceedAfter2Seconds()
3.         {
4.             float elapsed = 0f;
5.             float timer = 2f;
6.  
7.             while(!CustomTimer(timer, ref elapsed))
8.             {
9.                 yield return null;
10.             }
11.  
12.             Assert.IsTrue(elapsed >= timer);
13.         }
14.  
15.         private bool CustomTimer(float time, ref float elapsed)
16.         {
17.             elapsed += Time.deltaTime;
18.             return elapsed >= time;
19.         }

As part of the 3 A's. I'd consider the floats the arrange, the method the act, and so I would (for me) separate the assert outside of the method below the while statement.

 

Hey Nigey!

Thanks for your suggestion - I think I can work with that ^^
