An error occurred while analysing this project after it was built: System.NullReferenceException

Hi All,

first all thanks for Ncrunch. I used in the past without any problem.

Now with a new project (empty for now), just a proof of concept I have this error:

An error occurred while analysing this project after it was built: System.NullReferenceException: Object reference not set to an instance of an object.

VS 2010
.net 4

this the library on the failed project
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="Moq" version="4.0.10827" targetFramework="net40" />
<package id="NUnit" version="2.6.1" targetFramework="net40" />

can anyone help me?

thanks

Hi Daniele,

Thanks for posting!

This is an internal NUnit issue that I would guess is being caused somehow by the structure of one of your tests/fixtures. Is there any chance I could take a look at this source code? If you only have a few tests in the project, a copy/paste of this would be fine (if you are able to do so).

Something that may make a difference is to downgrade your NUnit dependency to 2.6.0. I'm not sure if this will have an impact on the other components you are using, though it could help to confirm whether this is problem is related to your NUnit version (1.41b of NCrunch uses NUnit 2.6.0).


Cheers,

Hi,

I think you are right. In the project where Nchrunch works I use:
<package id="NUnit" version="2.6.0.12054" />

Let me see if I can fix changing the version.

public class AutoMockBase<T> : MockBase where T : class
{
public MoqAutoMocker<T> AutoMocker { get; set; }

#region Setup/Teardown
[SetUp]
public override void SetUp()
{
base.SetUp();
AutoMocker = new MoqAutoMocker<T>();
AutoMocker.MockObjectFactory(); }
.....
}


[TestFixture]
public abstract class MockBase
{
#region Setup/Teardown
[SetUp]
public virtual void SetUp()
{

}
[TearDown]
public virtual void TearDown()
{
Container = null;
}
....
}

let me suggest something if i can:

Will be great if you can make overridable the version of the components like Nunit etc.
Give a better message on the error (the version is quite easy to fix the problem)
Write the requirement fro Ncrunch. I didn't find them anywhere.



for the rest is a great tool.

I'll note the NUnit 2.6.1 issue down to be resolved in a future build, hopefully v1.42. Thanks for making me aware of it!

Cheers,

Remco
