Telerik Test Studio test list run from Azure pipeline fails when triggered by a build completion of another project

[Stephen]

The Test Studio pipeline seems to fail consistently when triggered by a build. However, when we subsequently, manually, run the same Test Studio pipeline, it runs fine.

What are we missing?

This is how we are invoking the test list in the Azure pipeline:

"C:\Program Files (x86)\Progress\Test Studio\Bin\ArtOfTest.Runner.exe" list="TestLists/Test Placer Title Companion (Seller) - Test.aiilist" junit

Hi Stephen, 

Please, share the aiiresult file generated from the failing pipeline. You can find where it is stored in the build log and then send it zipped.

Below is the error. Note, I ran the same pipeline, with no changes, twice. Both times were successful.

elena, any update...?

Hi Stephen, 

As far as I understand the pipeline runs successfully for some of the triggers. That mean that the issue is related to some misynchronization between sending the actions from test and the page responsiveness. 

Based on the error log it seem that there is an AJAX timeout set which is not always sufficient.

After 2000 ms AJAX request is still pending.

Please, check the steps which use the AJAX timeout step property and ensure to increase it - the current 2 seconds are really short timeout. You can set this timeout even to 10-15 seconds as it will be waited only if needed. 

Let me know if this changes the outcome of the pipeline run.

Elena
