Visual Studio 2010 Test Project - Typemock Isolator Add-In

I've spent 6 hours wondering why running a unit test within Visual Studio 2010 started failing. It appears to work OK when the setting host is configured to run in a 64 bit process on a 64 bit machine - but set it to force tests to run in a 32 bit process and the test fails.

The tests fail on VS2010. I have a simple unit test project with a single test that reads Assert.IsTrue(true);

Visual Studio says "Test Run Error" and "Test Host Process exited unexpectedly" and "Failed to queue test run <blah>: Unable to start the agent process"

The event viewer logs:

AgentProcess cannot register with AgentService, make sure service is running.
(QTAgent32.exe, PID 5828, Thread 1) AgentProcess: could not register with agent service: System.InvalidProgramException: Common Language Runtime detected an invalid program.

at Microsoft.VisualStudio.TestTools.Execution.AgentContext.AddAgentProcessChannelUri(IChannelReceiver receiver)
at Microsoft.VisualStudio.TestTools.Agent.AgentProcess.Run()
I configured Agent32.exe.config to log:

<system.diagnostics>
    <switches>
      <!-- You must use integral values for "value".
           Use 0 for off, 1 for error, 2 for warn, 3 for info, and 4 for verbose. -->
      <!-- <add name="EqtTraceLevel" value="2" /> -->
   <add name="EqtTraceLevel" value="4" />
    </switches>
  </system.diagnostics>

<appSettings>
    <add key="CreateTraceListener" value="yes"/>
  </appSettings>

and then VSTTAgentProcess.log reports the following:

In the end I ran devenv.exe /safemode and by a process of elimination discovered that it was the Typemock Isolator add-in! I am running Typemock Isolator 6.1.2.

Our support agreement just expired. Is that conincidence? Does this add-in require a continual license to operate?

Test host process exited unexpectedly - Failed to queue test run: Unavle to start the agent process

All my unit tests started failing on VS2010. I don't know whether this was something to do with a VS2012 / .NET 4.5 install - I presume not as I'm convinced they were working after this.

Anyhow, they just stopped working.




























After 3 hours of investigation I found the way to get them working was to set
Test > Edit Test Settings > Hosts > Run tests in 32 bit or 64 bit process : Set to Run tests in 64 bit process on 64 bit machine

 

Note 32-bit debugging settings can be found in C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\QTAgent.exe.config. You can set the debug level to:

<switches>
      <!-- You must use integral values for "value".
           Use 0 for off, 1 for error, 2 for warn, 3 for info, and 4 for verbose. -->
      <add name="EqtTraceLevel" value="4" />
    </switches>

Use ProcMon to check that it is the QTAgent.exe that is being executed. VS2012 uses a different process.

Telerik MVC extensions and JQuery UI - Object doesn't support this property or method - JQuery conflict

I had a problem where I had an MVC project that used the Telerik MVC Grid.

This uses jquery-1.7.1-min.js.

But I also updatd my project folder to include jquery-1.8.2.js elsewhere in order to use JQuery UI's tooltips.

When I ran the project I got a Javascript error:

Object doesn't support this property or method on
$(document).tooltip();
This was because JQuery was referenced twice in the the HTML outputs.

So I then deleted the  jquery-1.7.1-min.js that was present in Telerik's 2012.2.607 folder. However this then caused another problem whereby javascript was complaining that

0x800a01b6 - Microsoft JScript runtime error: Object doesn't support property or method 'tDropDownList'

This was because Telerik's JQuery was removed.

The solution was to use:
@Scripts.Render("~/bundles/jquery")

at the top of the HTML page and set JQuery(false) on Telerik:

@(Html.Telerik().ScriptRegistrar().Globalization(true).jQuery(false).DefaultGroup(group => group.Combined(true).Compress(true)))

This results in JQuery being added at the top of the HTML and prevents Telerik adding another script tag.

Telerik MVC Extensions Grid - AJAX in cell editing (batch editing) with readonly columns

If you are using AJAX in-place editing, if a column is readonly then the value will not be passed to the controller on the update AJAX method.

The solution is to remove the ReadOnly attribute from the datasource viewmodel, and instead apply it to the column.

ViewModel
public class TransactionViewModel {
[  [ReadOnly(true)]
  public Int32 DealNum { get; set; }
}

View
columns.Bound(m => m.DealNum).Width(70).Title("Deal No.").ReadOnly();

EF5.0 Code First - The model backing the 'xxxContext' context has changed since the database was created. Consider using Code First Migrations to update the database

I created a simple bit of code to load data from an existing table into a POCO. However as I was developing the POCO I got this error.

The model backing the 'xxxContext' context has changed since the database was created. Consider using Code First Migrations to update the database

This is because EF creates a table [dbo].[__MigrationHistory] when it is first run and stores the model in there. If you subsequently change the POCO it differs from the saved model and this error is thrown.

My solution was to delete the table and thus any reference to the historical model.

using (var context = new EndurContext())

{

using (var conn = new SqlConnection(connections["EndurContext"]))

{

using (var command = conn.CreateCommand())

{

command.CommandType = CommandType.StoredProcedure;

command.CommandText = "[trade].[GetPhysFixedDeals]";

conn.Open();

using (var reader = command.ExecuteReader(CommandBehavior.CloseConnection))

{

var jobs =

((IObjectContextAdapter) context).ObjectContext.Translate<PhysicalFixedDeal>(reader);

}

}

}

}
