NUnit - Constraints

Links

Constraint-Based Assert Model (NUnit 2.4)

Exception

I checked that an exception was thrown like this (not sure it is the best way though):

Exception result = null;
try
{
    fileManager.doSomeStuff();
}
catch (Exception e)
{
    result = e;
}
Assert.That(result, Is.TypeOf(typeof(MySampleException)));

Sample

using NUnit.Framework;
using NUnit.Framework.SyntaxHelpers;

    [Test]
    public void testIsNew()
    {
        Assert.That(idx1.isNew(), Is.True);
    }

    [Test]
    public void testIsNewNot()
    {
        Assert.That(idx2.isNew(), Is.False);
    }

Is

The type or namespace name 'Is' could not be found (are you missing a using directive or an assembly reference?)

Add using NUnit.Framework.SyntaxHelpers to your source file…
