A really simple few lines of code to get a dirty load tester going. So easy in fact, it's a single class that could just be copied over. Meaning if you are unable to clone, or download an .exe, the copying is super simple.
I needed a really quick and dirty load tester and I wasn't in a position to clone or download projects/libraries/software... So this thing was created 💀
All the magic is in LoadTestEngine.cs.
The core concept is the "test group" and inside each group is each bunch of requests you're looking to fire at once. Plus a test group has what value of delay to wait before the next bunch of requests. For example, let's say you wanted to do 5 requests every 2 seconds. This is two test groups with five tasks in each, with the delay set to 2000ms.
See the example below for a more clear picture.
public record TestGroup(List<Task> TestTasks, int PostTestDelay);Where:
| Parameter | Usage |
|---|---|
TestTasks |
All the request to be made per test group. A list of normal C# Task objects. |
PostTestDelay |
The delay in milliseconds before the next test group. |
Note: The final delay actually doesn't matter as the code will end after the delay value.
With this solution is a test server which is a simple minimal API project to help goes along with the default load testing project. Run both at the same time to see the console fill with requests.
With the raw HttpClient object sitting there, you should be able to quickly attach anything else you need in the same way you probably have done it in your normal project.
With limitations of HttpClient around things like headers, you may want to create an HttpClient object as per what you need and add it to TestGroup or create an object to represent TestTasks which has the Task and anything else you need to run your test for each run.
