FloatEqualityComparer.Equals

Parameters

Returns

bool Return true if expected and actual values are equal, else false.

Description

Compare the actual and expected float values for equality.

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

using UnityEngine.TestTools.Utils;

[TestFixture]

public class FloatsTest
{
    [Test]

    public void FloatsAreEqual()
    {
        var comparer = new FloatEqualityComparer(10e-6f);

        var actual = -0.00009f;

        var expected = 0.00009f;

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

        //Default allowed relative error 0.0001f

        actual = 10e-8f;

        expected = 0f;

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