Syntax

public static class ConstraintExtensions

Methods

AllocatingGCMemory(ConstraintExpression)

Use this with NUnit's Assert.That() method to make assertions about the GC behaviour of your code. The constraint executes the delegate you provide, and checks if it caused any GC memory to be allocated. If any GC memory was allocated, the constraint passes; otherwise, the constraint fails. See https://docs.unity3d.com/Packages/com.unity.test-framework@1.1/api/UnityEngine.TestTools.Constraints.AllocatingGCMemoryConstraint.html for an example.
