Classic Model

The classic Assert model uses a separate method to express each individual assertion of which it is capable.

Here's a simple assert using the classic model:

StringAssert.AreEqualIgnoringCase("Hello", myString);

The Assert class provides the most common assertions in NUnit:

• ClassicAssert.True
• ClassicAssert.False
• ClassicAssert.Null
• ClassicAssert.NotNull
• ClassicAssert.Zero
• ClassicAssert.NotZero
• ClassicAssert.IsNaN
• ClassicAssert.IsEmpty
• ClassicAssert.IsNotEmpty
• ClassicAssert.AreEqual
• ClassicAssert.AreNotEqual
• ClassicAssert.AreSame
• ClassicAssert.AreNotSame
• ClassicAssert.Contains
• ClassicAssert.Greater
• ClassicAssert.GreaterOrEqual
• ClassicAssert.Less
• ClassicAssert.LessOrEqual
• ClassicAssert.Positive
• ClassicAssert.Negative
• ClassicAssert.IsInstanceOf
• ClassicAssert.IsNotInstanceOf
• ClassicAssert.IsAssignableFrom
• ClassicAssert.IsNotAssignableFrom
• Assert.Throws
• Assert.ThrowsAsync
• Assert.DoesNotThrow
• Assert.DoesNotThrowAsync
• Assert.Catch
• Assert.CatchAsync

Additional assertions are provided by the following classes, which are also in the NUnit.Framework.Legacy namespace:

• String Assert
• Collection Assert
• File Assert
• Directory Assert

Notes

• The exception-family of classic asserts have not yet been moved to the legacy namespace. They have not yet full equivalents in the constraint model.
