Introduction

An update rollup is available that resolves the following issues for the testing tools in Microsoft Visual Studio 2010 Service Pack 1 (SP1).

Issue 1

When you run tests on the test agent that is installed on a computer that has Visual Studio 2010 SP1 installed, the tests may not run, and the following error is logged:

Attempted to access an unloaded AppDomain. (Exception from HRESULT: 0x80131014)

Issue 2

When you run a playback of a coded UI test on certain Windows Presentation Foundation (WPF) controls, a Microsoft.VisualStudio.TestTools.UITest.Extension.UITestControlNotFoundException exception occurs, and then you receive the following error message:

"Search may have failed at '<name>' <control type> as it may have virtualized children. If the control being searched is descendant of '<name>' <control type> , including it as the parent container may resolve the problem."

Notes

  • This exception may be generated because the WPF controls are deep in the UI control hierarchy. Therefore, the control cannot be addressed in the recorded QuerID UI control hierarchy in the UI map. After you install this update, the control can be addressed.

  • After you install this update, the following key is added to CodedUITestBuilder.exe.config/MTM.exe.config files in order to resolve this issue: 

    <add key="MaxLevelsForItemContainer" value="<desiredLevel>"/>

  • UI Test Framework searches the UI hierarchy until it reaches an instance of <desiredLevel> to identify a parent container. By default, <desiredLevel> is set to 2. Set <desiredLevel> to an appropriate value for your situation.

  • If you set <desiredLevel> to a high value, performance may be affected when a recording operation occurs.


Issue 3

Assume that you try to create a work item from the Test Results pane in Visual Studio 2010 after you connect to a Team Foundation Server (TFS) server. In this situation, a System.OutOfMemory exception occurs, and the creation operation fails. This issue frequently occurs if the TFS server has many builds.

Issue 4

When some tests run in a build operation, some builds that are queued in a TFS server stop responding. Additionally, the following error is logged in the build log:

Waiting to publish...

Publishing results of test run <build name> to http://<TFS server address>:8080/tfs/DefaultCollection...

The process cannot access the file '<directory>\data.coverage' because it is being used by another process.



Publish failed or canceled.

Note This issue occurs because the Mstest.exe process crashes. When a non-test thread encounters an assertion failure or a nonfatal exception that is unhandled, the Mstest.exe process crashes if code-coverage collector is enabled for the test run. 

This issue may occur when tests run in an MSBuild script. MSBuild scripts skip the test run step.
