Vector3EqualityComparer

Use this class to compare two Vector3 objects for equality with NUnit constraints. Call Vector3EqualityComparer.Instance comparer to perform a comparison with the default calculation error value 0.0001f. To specify a different error value, use the one argument constructor to instantiate a new comparer.

Static properties

Syntax	Description
Instance	A comparer instance with the default calculation error value equal to 0.0001f.

Constructors

Syntax	Description
Vector3EqualityComparer(float allowedError)	Creates an instance with a custom error value.

Public methods

Syntax	Description
bool Equals(Vector3 expected, Vector3 actual)	Compares the actual and expected Vector3 objects for equality using Utils.AreFloatsEqual to compare the x, y, and z attributes of Vector3.

Example

[TestFixture]
public class Vector3Test
{
    [Test]
    public void VerifyThat_TwoVector3ObjectsAreEqual()
    {
        // Custom error 10e-6f
        var actual = new Vector3(10e-8f, 10e-8f, 10e-8f);
        var expected = new Vector3(0f, 0f, 0f);
        var comparer = new Vector3EqualityComparer(10e-6f);

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

        //Default error 0.0001f
        actual = new Vector3(0.01f, 0.01f, 0f);
        expected = new Vector3(0.01f, 0.01f, 0f);

        Assert.That(actual, Is.EqualTo(expected).Using(Vector3EqualityComparer.Instance));
    }
