Custom Comparisons

ExpectedObjects supports custom comparisons by assigning anonymous properties an instance of an object which implements IComparison. A static Expect type is provided which currently supplies the following convenience methods:

• Expect.Any<T>()
• Expect.Any<T>(Expression<Func<T, bool>> predicateExpression)
• Expect.Null()
• Expect.NotNull()
• Expect.Default<T>()
• Expect.NotDefault<T>()

The following example shows how a property can be configured to expect any non-null value:

var expected = new
{
        Name = "John Doe",
        DateTime = DateTime.Today,
        VerificationCode = Expect.NotNull()
}.ToExpectedObject();
