Error: Arrange a method with a params argument

[Kevin Schneider]

I am trying to arrange the following:

TEntity GetByKey(params object[] keyValues);

using:

const long id = 1;
Mock.Arrange(() => _appSettingRepository.GetByKey(id)).Returns(() => null);

This is failing with the following:

Get_app_setting_by_invalid_key_should_return_null' failed: System.NullReferenceException : Object reference not set to an instance of an object.

I should have also mentioned I am using version 2011.1.331.1

Hi Kevin,

You are right about the issue. It is throwing exception when params of type object[] is passed with value type argument(s). However the issue is fixed and should you require an internal build, please let us know and in that case, please also open up a support ticket (Since we can't send internal builds in public forum) so that we can send you one.

In addition this will also be included in a service pack to be released shortly; therefore you can wait for that as well if not urgent.

Kind Regards,
Ricky
