Mecha is a C# library that enables automatic testing of classes with the goal of finding ways to break the code. It provides various testing capabilities such as unit testing, security testing through data fuzzing, checking for concurrency issues, and verifying fault tolerance. With just a single line of code, Mecha can automatically test every method in a class. The library seamlessly integrates with your existing testing framework.
Get Started
$ dotnet add package Mecha.xUnitReadme
I try to make idiot proof software but the world keeps making better idiots.
Or at least that's how it seems to us much of the time. You post a new application feature and the user's find a way to break it. In reality it's because we didn't think of an edge case that they found. I mean who can possibly think up all of these possibilities? A cracked out squirrel? Perhaps a raccoon with ADHD? Neither really work out in the long run as eventually they rise up against society to overthrow it. They're trained with computers at that point so there is no stopping them. And personally I'm too lazy to do this myself so I guess that leaves writing some code to do it, but thankfully I've already done that for you.
Mecha is a library to automatically test classes with the ultimate goal being to find ways to break the code. It can help with unit testing, security testing via data fuzzing, testing for concurrency issues, and check for fault tolerance. With one line of code, you can test every method in a class automatically. Best part is it ties into the testing framework that you're already using.
The Code and What It's Doing
Mech.BreakAsync<MyClass>();
Seriously, that's it. With that Mecha searches for any public methods and properties, loops through them, finds interesting inputs for the methods, and runs them looking for exceptions to be thrown. Once an exception is thrown, it then uses the input to find the smallest possible value that still results in an issue. It then saves these issues as test cases for the future.
