Test Utils

This contains test utility functions for float value comparison and creating primitives.

Static Methods

Syntax	Description
`bool AreFloatsEqual(float expected, float actual, float allowedRelativeError)`	Relative epsilon comparison of two float values for equality. `allowedRelativeError` is the relative error to be used in relative epsilon comparison. The relative error is the absolute error divided by the magnitude of the exact value. Returns `true` if the actual value is equivalent to the expected value.
`bool AreFloatsEqualAbsoluteError(float expected, float actual, float allowedAbsoluteError)`	Compares two floating point numbers for equality under the given absolute tolerance. `allowedAbsoluteError` is the permitted error tolerance. Returns `true` if the actual value is equivalent to the expected value under the given tolerance.
`GameObject CreatePrimitive( type)`	Creates a GameObject with a primitive MeshRenderer. This is an analogue to the GameObject.CreatePrimitive, but creates a primitive `MeshRenderer` with a fast Shader instead of the default built-in `Shader`, optimized for testing performance. `type` is the primitive type of the required `GameObject`. Returns a `GameObject` with primitive `MeshRenderer` and Collider.

Example

[TestFixture]
class UtilsTests
{
    [Test]
    public void CheckThat_FloatsAreEqual()
    {
        float expected = 10e-8f;
        float actual = 0f;
        float allowedRelativeError = 10e-6f;

        Assert.That(Utils.AreFloatsEqual(expected, actual, allowedRelativeError), Is.True);
    }
	
    [Test]
    public void CheckThat_FloatsAreAbsoluteEqual()
    {
        float expected = 0f;
        float actual = 10e-6f;
        float error = 10e-5f;

        Assert.That(Utils.AreFloatsEqualAbsoluteError(expected, actual, error), Is.True);
    }
