Custom equality comparers with equals operator
If you need to compare Vectors using the overloaded operator == (see Vector2.operator ==, Vector3.operator ==, and Vector4.operator ==) you should use the respective comparer implementations:
- Vector2ComparerWithEqualsOperator
- Vector3ComparerWithEqualsOperator
- Vector4ComparerWithEqualsOperator
The interface is the same as for other equality comparers except the public constructor error parameter is inapplicable in this case.
Example
[TestFixture]
public class Vector3Test
{
[Test]
public void VerifyThat_TwoVector3ObjectsAreEqual()
{
var actual = new Vector3(10e-7f, 10e-7f, 10e-7f);
var expected = new Vector3(0f, 0f, 0f);
Assert.That(actual, Is.EqualTo(expected).Using(Vector3ComparerWithEqualsOperator.Instance));
}
}
