Rucksack

A simple load testing library for .NET.

Getting Started

Add Rucksack as a dependency via NuGet:

dotnet add package Rucksack --prerelease

Define your options with your preferred strategy, and call Run:

using Rucksack;
using Rucksack.LoadStrategies;

var options = new LoadTestOptions
{
    LoadStrategy = new RepeatBurstLoadStrategy(
        countPerInterval: 10,
        interval: TimeSpan.FromSeconds(1),
        totalDuration: TimeSpan.FromSeconds(10)),
};

await LoadTestRunner.Run(async () =>
{
    // do something to put load on the system...
    await Task.Delay(1000);
}, options);

Load Strategies

There are a couple built-in strategies for generating load, or you can implement ILoadStrategy yourself for custom logic.

• ConstantUserLoadStrategy: Attempts to maintain a constant concurrent user load at each given check interval until the given duration has passed.
• OneShotBurstLoadStrategy: Enqueue the given number of tasks all at once. Does not repeat.
• RepeatBurstLoadStrategy: Repeat enqueueing the given count of tasks at each given interval until the given duration has passed.
• SequentialLoadStrategy: An aggregate strategy that executes multiple load strategies in order. Great for creating scenarios like step up, then hold steady, then step down.
• SteppedBurstLoadStrategy: Enqueue an increasing (or decreasing) burst of tasks in a stepwise manner, regardless of how many are still running.
• SteppedUserLoadStrategy: Attempts to maintain an increasing (or decreasing) concurrent user load in a stepwise manner.
