QuaternionEqualityComparer.Equals

Parameters

Returns

bool Returns true if expected and actual objects are equal, else false.

Description

Compares the actual and expected Quaternion objects for equality.

As shown in the example, this method will be called by NUnit when we use it with constraints.

        var expected = new Quaternion(1f, 10f, 0f, 0f);

        var comparer = new QuaternionEqualityComparer(10e-6f);

        Assert.That(actual, Is.EqualTo(expected).Using(comparer));

        //Using default error 0.00001f

        actual = new Quaternion(10f, 0f, 0.1f, 0f);

        expected = new Quaternion(1f, 10f, 0.1f, 0f);

        Assert.That(actual, Is.EqualTo(expected).Using(QuaternionEqualityComparer.Instance));
