Use this class to compare two Vector2 objects for equality with NUnit constraints. Use the static Vector2EqualityComparer.Instance to have the calculation error value set to default 0.0001f. For any other error value, instantiate a new comparer object with the one argument constructor.
Static properties
Syntax
Description
Instance
A comparer instance with the default error value set to 0.0001f.
Constructors
Syntax
Description
Vector2EqualityComparer(float error)
Creates an instance with a custom error value.
Public methods
Syntax
Description
Equals(Vector2 expected, Vector2 actual)
Compares the actual and expectedVector2 objects for equality using the Utils.AreFloatsEqual method.
Example
[TestFixture]
public classVector2Test
{
[Test]
public voidVerifyThat_TwoVector2ObjectsAreEqual()
{
// Custom calculation error
var actual = new Vector2(10e-7f, 10e-7f);
var expected = new Vector2(0f, 0f);
var comparer = new Vector2EqualityComparer(10e-6f);
Assert.That(actual, Is.EqualTo(expected).Using(comparer));
//Default error 0.0001f
actual = new Vector2(0.01f, 0.01f);
expected = new Vector2(0.01f, 0.01f);
Assert.That(actual, Is.EqualTo(expected).Using(Vector2EqualityComparer.Instance));
}
