Been working with the fine folks at the Game Studios labs and they just recently ran to the following error when they finish a load test run:

“There was an error importing the result file after a load test run.”

The cause in their case was their Load Test repository had filled up.  In Visual Studio 2013 we started automatically creating and connecting to a local SQL Express interest for load run data.

By default this is located at:

Data Source=aidemo008\sqlexpress;Initial Catalog=LoadTest2010;Integrated Security=True

C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\LoadTest2010.mdf

 

Which is GREAT for getting started as it is one less thing to setup BUT since you weren’t told there was a SQL Database created for you, when it fills up it can come as a bit of a surprise.

Depending upon the version of SQL Express, this can be 4gb or 10 gb.

Luckily it is easy to fix by simply running the command: loadtestresultsrepository.sql.
