Assert.AreEqual

Утверждает, что значения равны.

Показать сообщение, если expected и actual не равны. Если сравнитель не указан, используется EqualityComparer<T>.Default.

using UnityEngine;
using UnityEngine.Assertions;

public class AssertionExampleClass : MonoBehaviour
{
    void Update()
    {
        // Make sure the Game Object is always tagged as "Player"
        Assert.AreEqual("Player", gameObject.tag);
    }
}

Еще один пример:

using UnityEngine;
using UnityEngine.Assertions;

// Assert.AreEqual and Assert.AreNotEqual example
//
// Compare 32 to 32. AreNotEqual prints message.
// Compare 32 to 33. AreEqual prints message.

public class Example : MonoBehaviour
{
    void Start()
    {
        int expectedInt = 32;
        int actualInt = 32;

        // Do not show message (32 is equal to 32).
        Assert.AreEqual(expectedInt, actualInt, "AreEqual: " + expectedInt + " equals " + actualInt);

        // Show message (32 is equal to 32).
        Assert.AreNotEqual(expectedInt, actualInt, "AreNotEqual: " + expectedInt + " not equal to " + actualInt);

        actualInt = 33;

        // Show message (32 is not equal to 33).
        Assert.AreEqual(expectedInt, actualInt, "AreEqual: " + expectedInt + " equals " + actualInt);

        // Do not show message (32 is not equal to 33).
        Assert.AreNotEqual(expectedInt, actualInt, "AreNotEqual: " + expectedInt + " not equal to " + actualInt);
    }
