QuaternionEqualityComparer
Use this utility to compare two Quaternion objects for equality with NUnit assertion constraints. Use the static instance QuaternionEqualityComparer.Instance to have the default calculation error value set to 0.00001f. For any other custom error value, use the one argument constructor.
Static properties
| Syntax | Description |
|---|---|
Instance |
A comparer instance with the default error value 0.00001f. |
Constructors
| Syntax | Description |
|---|---|
QuaternionEqualityComparer(float allowedError) |
Creates an instance of the comparer with a custom allowed error value. |
Public methods
| Syntax | Description |
|---|---|
bool Equals(Quaternion expected, Quaternion actual) |
Compares the actual and expected Quaternion objects for equality using the Quaternion.Dot method. |
Example
[TestFixture]
public class QuaternionTest
{
[Test]
public void VerifyThat_TwoQuaternionsAreEqual()
{
var actual = new Quaternion(10f, 0f, 0f, 0f);
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));
}
