Coded UI Tests: When debugging, function evaluation time out

Most of the coded ui developers may encounter this situation. When they want to debug a script and they want to add watch on a particular object or property, this message "function evaluation time out" may display.

This results in frustration and developers have to manually find the bug.

To overcome this situation I begin to research about this particular issue. I cannot find anything on the blogs and forums. They all seem to say one thing only that this error occurs due to bad programming practice etc.

But luckily I found the solution and it is very simple.

Just open your .testsettings file (Located under solution items folder) . My test setting name was TraceAndTestImpact.testsettings

Open it with XML Text Editor.

You will see something like this

xml
version="1.0"
encoding="UTF-8"?>

<TestSettings
name="Trace and Test Impact"
id="1494f279-051d-465d-97a9-e57b59372376"
xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010">

<Description>These are test settings for Trace and Test Impact.</Description>

<Execution>

<ExecutionThread
apartmentState="MTA" />

Just comment out the selected line

xml
version="1.0"
encoding="UTF-8"?>

<TestSettings
name="Trace and Test Impact"
id="1494f279-051d-465d-97a9-e57b59372376"
xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010">

<Description>These are test settings for Trace and Test Impact.</Description>

<Execution>

And restart visual studio.

You will now be able to debug without having function evaluation time out message. Inshallah.
