Visual Studio : Resolving the LoadGeneratorLocationError
Published On: March 8, 2017
Categories: Testing, Visual Studio 3
I use Visual Studio for performance testing and overhead analysis with the SentryOne products. Currently, I have Microsoft Visual Studio Enterprise 2015 Version 14.0.25431.01 Update 3 installed. Since the first edition of 2015 (possibly even Visual Studio 2013), I've received a LoadGeneratorLocationError during each Load Test execution.
|Test Error||LoadGeneratorLocationError||1||Geo locations configured with load test will only be honored with load
test runs using Visual Studio Team Services and will be ignored while
running your load test on-premises.
Visual Studio Load Test Error
Since I am running the test locally, this error is noise. Furthermore, no one wants to see an error in an otherwise successful test. It simply ruins the final results report. In addition, when the Load Test was created, "On-premise Load Test" was selected, which makes this frustrating. Possibly more frustrating is that it's called "On-premise" when you get started in the New Load Test Wizard.
Visual Studio New Load Test Wizard
I continued through the wizard and created the example Load Test shown below.
|Load Test Example||Default Location Properties|
|Visual Studio Example Load Test||Visual Studio Location Default Properties|
First, if I right-click on the Location --> Default I have only the options to "Set Location for Cloud-based Load Tests" or go to "Properties". As you may have noticed in the image above, there's not anything I can set for "Properties" as-is.
Next, I'll run the Load Test with the default settings. Now, you can see that the error appears on the Load Test Results output.

Due to the emotional stress caused by this error appearing on all of my results, I sought a way to make it disappear. So far, the only way I know how is to edit the LoadTest as an XML file.
First, right-click on a .loadtest file in Solution Explorer and select "Open With".
Visual Studio loadtest Open With
Second, select the XML (Text) Editor in the "Open With" window.
Visual Studio loadtest Open With Window
Then, find the "LoadGeneratorLocations" tag, and delete the three lines I have highlighted. They should be located near the end of the file.
<LoadGeneratorLocations> <GeoLocation Location="Default" Percentage="100" /> </LoadGeneratorLocations>
Visual Studio loadtest Edit XML
Next, click the Save icon and close the XML window.
Visual Studio loadtest Edited XML Saved
Finally, right-click the .loadtest file again in Solution Explorer and Open With "Load Test Editor (Default)" so it opens normally instead of with the XML Editor going forward.
Now, when the test executes, there are no more errors (well, not any for LoadGeneratorLocationError anyway).
Visual Studio loadtest No Errors
Fantastic! That's what everyone wants to see at the end of a test.
I hope this workaround is useful. Even more so, I hope Visual Studio 2017 requires no workarounds to avoid this error.
