ArgumentNullExc         


        

Answer 1

public static class ExceptionAssert
{
  public static T Throws(Action action) where T : Exception
  {
    try
    {
      action();
    }
    catch (T ex)
    {
      return ex;
    }

    Assert.Fail("Expected exception of type {0}.", typeof(T));

    return null;
  }
}

You can use the extension method above as a test helper. Here is an example of how to use it:

// test method
var exception = ExceptionAssert.Throws(
              () => organizations.GetOrganization());
Assert.AreEqual("lawbaseFixedContactRepository", exception.ParamName);
