ConditionalIgnore attribute

This attribute is an alternative to the standard Ignore attribute in NUnit. It allows for ignoring tests only under a specified condition. The condition evaluates during OnLoad, referenced by ID.

Example

The following example shows a method to use the ConditionalIgnore attribute to ignore a test if the Unity Editor is running macOS:

using UnityEditor;
using NUnit.Framework;
using UnityEngine.TestTools;

[InitializeOnLoad]
public class OnLoad
{
    static OnLoad()
    {
        var editorIsOSX = false;
        #if UNITY_EDITOR_OSX
            editorIsOSX = true;
        #endif
        
        ConditionalIgnoreAttribute.AddConditionalIgnoreMapping("IgnoreInMacEditor", editorIsOSX);
    }
}

public class MyTestClass
{
    [Test, ConditionalIgnore("IgnoreInMacEditor", "Ignored on Mac editor.")]
    public void TestNeverRunningInMacEditor()
    {
        Assert.Pass();
    }
}

Note: You can only use InitializeOnLoad in Edit Mode tests.
