New Post: DateTime.Now not getting intercepted

ulu — Sat, 28 Jul 2012 06:27:45 GMT

Sorry, but that's better asked at the Typemock forums as well. This is related to some Isolator internals, which I don't understand at all.

I clarified this with them, thanks. I have another issue though. My application uses Spring .net and when I added CThru to it, it stopped working. In the typemock logs, I see it failing silently at this point

Exposing internals for module 122F1160Loaded: ->C:\Program Files (x86)\ITG\Custom\Active\bin\Spring.Core.dll

Is it not possible to have both enabled?

New Post: DateTime.Now not getting intercepted

SamwellTarly — Thu, 26 Jul 2012 18:19:02 GMT

I managed to get it to run correctly, but I had to add the [TextFixture] attribute to the class and [Test] attribute to the program. Also, it only works correctly when i run it through visual studio, when I run it via the TMockRunner.exe, the datetime.now property does not get intercepted. Is there any way to fix that? I am running Isolator V7.

Thanks!

No it doesn't matter.

What do you have in your output when you run my test? Here's what I get:

TypeMock.Interceptors.InterceptDateTime.get_Now()
01.01.0001 0:00:00

You can see that it is actually the InterceptDateTime object that is intercepted.

What's your Isolator version?

Thanks for your reply.

I tried running your code but I'm having the same issue. The DateTime.Now value does not get overridden..

I put a writeline in the ShouldIntercept method in my AspectClass and I do not even see the DateTime.Now property being intercepted there. This is the output

CThru.BuiltInAspects.MissingMethodAspect .ctor
CThru.Aspect .ctor
CThru.CThruEngine AddAspect
CThru.CThruEngine GetUniqueKey
CThru.CThruEngine AddAspect
CThru.CThruEngine get_Verbose
CThru.CThruEngine+AspectHandler .ctor
CThru.CThruEngine add_DuringConstructorCall
CThru.CThruEngine add_DuringConstructorCall
CThru.CThruEngine add_DuringStaticConstructorCall
CThru.CThruEngine add_DuringStaticConstructorCall
CThru.CThruEngine add_duringMethodCall
CThru.CThruEngine add_duringMethodCall
CThru.CThruEngine add_missingMethodCall
CThru.CThruEngine add_missingMethodCall
ClassLibrary1.Class1 .ctor
ClassLibrary1.Class1 WriteTime
System.ComponentModel.Component Finalize
System.Diagnostics.Process Dispose
System.ComponentModel.Component Dispose

Does it matter that it is a property and not a method?

Hi,

Could you try and run the following test:

			CThruEngine.AddAspect(new Stub(info => info.MethodName == "get_Now").Return(new DateTime(1, 1, 1)));
			CThruEngine.StartListening();
			Console.WriteLine(DateTime.Now);

Works for me with the latest CThru

New Post: DateTime.Now not getting intercepted

SamwellTarly — Tue, 24 Jul 2012 17:18:34 GMT

Hi,

I new to Cthru and TypeMocks. I wrote a simple application and want to intercept DateTime.Now in the application. This is the code I have:

Aspect Class:

class CThruAspectClass : Aspect

{ public override bool ShouldIntercept(InterceptInfo info)

{ return info.MethodName == "get_Now"; }

public override void MethodBehavior(DuringCallbackEventArgs e) { base.MethodBehavior(e);
e.MethodBehavior = MethodBehaviors.ReturnsCustomValue;
e.ReturnValueOrException = new DateTime(1, 1, 1); }

}

I have this in main:

public static void Main(string[] args)

{ var assembly = typeof(MockManager).Assembly;
CThruAspectClass ctac = new CThruAspectClass();

CThruEngine.AddAspect(ctac);

CThruEngine.StartListening();
string path = somepath;

Class1 cl1 = new Class1();

cl1.WriteTime(path); }

The actual DateTime.Now method gets called in WriteTime which is in a different class. I read that mscorlib types cannot be intercepted in the main method but this should be ok, right?

I start up the application using TMockRunner.exe but I see that the current Date and Time get written not the overriden value. What am I doing wrong?

Any help will be appreciated!

Thank you!

Can you please download the cthru examples from

they should run just fine on your machine out of the box.

if they don't, we'll have a better a clue perhaps what is happening.

I'm happy that you have a vs2010 solution now.

The CThruAndSilverUnitTogether_vs2010 solution still had a few conversions when opened in VS2010.

The FluentAOP vs2010 Project isn't named vs2010 and therefore is missing in the Solution.

The complete solution wouldn't built as the FluentAOP.dll file was missing.

I think you simply need to create a FluentAOP_vs2010 project and this will build.

I got the same problem with the
public void SetChildTemplate()

in the file AutoCompleteBoxTests.cs

using TestDriven, Right click, Run Test.

error:

System.IO.FileNotFoundException: Could not load file or assembly 'System.Core, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified.

What's with VS2010 saying that it will automatically add System.Core?

Hope you can narrow down the problem.

Just committed a couple of project converted to the VS2010 format (except for the tests which should be converted just fine). Please try this.
