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:

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

Additional assertions are provided by the following classes:

• String Assert
• Collection Assert
• File Assert
