Exception:

"The load test results database could not be opened. Check that the load test results database specified by the connect string for your test controller (or local machine) specifies a database that contains the load test schema and that is currently available. For more information, see the Visual Studio help topic 'About the Load Test Results Store'. The connection error was: An error occurred while attempting to create the load test results repository schema: To create the database 'LoadTest2010' your user account must have the either the SQL Server 'sysadmin' role or both the 'serveradmin' and 'dbcreator' roles"

Check your remote test settings in VS solution. You should create a remote test settings in VS solution and specify the remote test controller.

Load Test: The test has not started yet

by Xavier Dilip Kumar 4. February 2014 14:06

Exception:

"The test has not started yet"

Explanation:

The test run result window just lists the name of the machine from which it ran, but it never opens the results and also Test run state remains pending. After I double click on the machine test item it just says "The Test has not started yet". Not able to view the result online during load test execution time. 

 

Solution:

The VS 2010 client version which I used to execute the load was SP1. But the test rig environment version was only VS 2010 RTM. 

1. Installed the SP1 on test controller and agents

2. Reconfigured the agents to controller again.

Test Controllers TestRunStorage has filled up hard drive

by Xavier Dilip Kumar 31. May 2013 11:54

Explanation

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]

Workaround

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

Web Performance & Load Tests

Could not access the load test results repository: The load test results repository is out of space. Allocate more space to the repository (if possible), or delete results of the older load test runs.

by Xavier Dilip Kumar 8. May 2013 09:46

Problem

The load test rig database was configured on SQL Server 2008 express edition which can hold maximum database size of 4 gb

Workaround

Note: Always test the blog script on your test environment before executing on production environment

This problem can be overcame by removing historical results

-- Start Script

-- This script deletes all load test run older than two weeks
-- To change the timeframe, change the number of days from 14 to the desired number
 
USE LoadTest
DECLARE @LoadTestRunId int
DECLARE OldLoadTestsCursor CURSOR FOR
    SELECT LoadTestRunId FROM LoadTestRun WHERE datediff(dd, StartTime, getdate()) > 14
 
OPEN OldLoadTestsCursor
FETCH NEXT FROM OldLoadTestsCursor INTO @LoadTestRunId
 
WHILE @@FETCH_STATUS = 0
BEGIN
    EXEC Prc_DeleteLoadTestRun @LoadTestRunId
    FETCH NEXT FROM OldLoadTestsCursor INTO @LoadTestRunId
END
 
CLOSE OldLoadTestsCursor
DEALLOCATE OldLoadTestsCursor

-- End Script

Script Reference :  http://blogs.msdn.com/b/billbar/archive/2006/02/09/528900.aspx

Solution

Configure the rig to other editions of SQL server.
