Custom equality comparers
To enable easier verification of custom Unity type values in your tests we provide you with some custom equality comparers:
- ColorEqualityComparer
- FloatEqualityComparer
- QuaternionEqualityComparer
- Vector2EqualityComparer
- Vector3EqualityComparer
- Vector4EqualityComparer
Use these classes to compare two objects of the same type for equality within the range of a given tolerance using NUnit or custom constraints . Call Instance to apply the default calculation error value to the comparison. To set a specific error value, instantiate a new comparer object using a one argument constructor ctor(float error).
Static properties
| Syntax | Description |
|---|---|
Instance |
A singleton instance of the comparer with a predefined default error value. |
Constructors
| Syntax | Description |
|---|---|
ctor(float error) |
Creates an instance of comparer with a custom error value.allowedError. The relative error to be considered while comparing two values. |
Public methods
| Syntax | Description |
|---|---|
bool Equals(T expected, T actual); |
Compares the actual and expected objects for equality using a custom comparison mechanism. Returns true if expected and actual objects are equal, otherwise it returns false. |
