How to perform stress testing/performance testing of UWP app that calls api

Question

I am looking for a way to do some performance testing of a UWP app that calls api's and uses radis cache. The application will continuously perform action for 100 hours or more and i need to make sure the server response time is consistent and does not deteriorate the application's action response after running for so many hours at a stretch. By the way, there is no scenario of having multiple users here. I am still on the learning curve and any help would be greatly appreciated.

Answer 1

You can use Microsoft built-in profiling and performance tools or 3rd-party profiler like YourKit .NET Profiler.

The end-user activity for the application can be simulated either in the application code itself or using 3rd-party tools like Windows Application Driver or Coded UI test

If you will need to simulate hundreds/thousands of applications communicating with the backend to load test the backend - you will need a load testing tool which supports protocol(s) used by your UWP application, check out How to Run Performance Tests of Desktop Applications Using JMeter for example test setup

Answer 2

You can add code that logs messages and events at certain points while your app runs. When you're testing your app, you can use profiling tools such as Windows Performance Recorder and Windows Performance Analyzer (both are included in the Windows Performance Toolkit) to create and view a report about your app's performance. UWP provides logging APIs, they are part of the Windows.Foundation.Diagnostics namespace. For more details, you can refer to this document.

In addition, you can also analyze the performance of UWP apps using Visual Studio diagnostic tools, e.g. CPU usage, memory leak, etc.
