Load testing with VSTS

To test HTTP-triggered functions, you can use the VSTS Web tests. These tests will allow you to estimate your response time and response latency from multiple locations on the globe, and identify if your function can perform well under increasing load.

Note

Creating load tests for non-HTTP-triggered functions involves triggering Unit Tests from load tests. We will not cover the process here.

This type of testing requires Visual Studio Enterprise edition.
