Simulating Peak Load with VS Load Tests

  • Artykuł

In VS load tests come with a few load patterns out of the box:

  • Constant load: holds count of users steady
  • Step load: steps the count of users up to some level then holds them steady
  • Goal-based load: adjusts the user load up and down to reach some goal

But what if you want to simulate several peak loads, such as users coming to a site at 8:00 a.m. and again at noon?

In VS 2008 SP1, we enabled extensibility in the load test engine to allow you to define your own load patterns.

Yun Tong on the VS load test team developed a load test plugin that allows you to define multiple, repeatable load patterns, which enables peak load modeling.
