Test Controllers TestRunStorage has filled up hard drive

by XDK 31. May 2013 11:54


When a load test is executed from the local machine the assemblies required to run the test are copied to the controller. The files are copied to a directory on the controller in the following location Drive:\Users\[USER]\AppData\Local\VSEQT\QTController.The Test results are copied to a directory on the controller in the following location Drive:\Users\<Account>\AppData\Local\VSEQT\QTController\TestRunStorage.
Each deployment and TestRunStorage will have a further directory named with a unique GUID where the files are copied.

For example

Deployment folder location: C:\Users\[USER ACCOUNT]\AppData\Local\VSEQT\QTController\[GUID]
TestRunStorage folder location : C:\Users\[USER ACCOUNT]\AppData\Local\VSEQT\QTController\TestRunStorage\[GUID]


Delete the folders under C:\Users\[USER ACCOUNT]\AppData\Local\VSEQT\QTController\. or a scheduled task to delete the folders periodically
