This video demonstrates creating an on-premises load test and then take it to the cloud with Windows Azure. The presentation starts by creating a test in Visual Studio and then recording web traffic using the Web Recorder and Internet Explorer. It also walks through using the Load Test Wizard to generate your load tests.
This video also shows you how you can see load test history, test results, and who started or triggered each test. The demonstration pulls all of these capabilities together to go from running a test, to identifying a slow down in his app, tracing the issue, and jumping right into debugging the section of code causing the issue.
