About Browser Mix
The browser mix gives you a way to simulate load more realistically in a load test scenario. Load is generated by using a heterogeneous mix of browsers instead of one single browser. You create a closer approximation of the browsers that will be used with your applications.
A browser mix specifies the probability of a virtual user running a particular browser type in a load test scenario. When you create a load test, you might want to simulate that load is being generated through more than one browser. When you add a browser type to the mix from the set of browsers provided, a set of associated headers for the selected browser is added to each HTTP request submitted by a Web test.
The browser mix works like other mix options. A browser type is randomly associated with a virtual user, based on the browser mix. That user's tests are run on a particular browser, based on the probability you specified in the mix.
After you have specified a browser mix, you can later add and remove browsers types to the mix. You also can change the distribution of the browser mix by using the mix control.
Mix Control
The mix control allows you to easily adjust the distribution of browsers in a scenario. For more information, see About the Mix Control.
Next Steps
To select a browser mix when you create a load test using the Load Test Wizard, or to change the browser mix in the Load Test Editor after you create a load test, see How to: Specify Browser Mix.
