Unit Testing for C# Developers

Picture this: you make a simple change to the code and suddenly realize that you created a dozen unexpected bugs. Sound familiar? You’re not alone! Good news is, unit testing can make this a thing of the past. Maybe you’ve heard of automated or unit testing before and you’re keen to learn more. Or perhaps you’ve tried to learn it and got a bit lost or ended up with fat and fragile tests that got in the way and slowed you down. Either way, what you need is a course that will teach you all you need to know about this essential skill - from the basics, right through to mastery level. What is unit testing? In a nutshell: it’s the practice of writing code to test your code and then run those tests in an automated fashion. Why learn unit testing? Why write extra code? Wouldn’t that take extra time to write? Would that slow you down? Why not just run the application and test it like an end user? Thinking like this is the mistake lots of people make. I used to make it myself. I’ve had to learn the hard way! I learned pretty fast that if you’re building a complex application or working on a legacy app, manually testing all the various functions is tedious and takes a significant amount of time. As your application grows, the cost of manual testing grows exponentially. And you’re never 100% sure if you’ve fully tested all the edge cases. You’re never confident that your code really works until you release your software and get a call from your boss or an end user! Several studies have shown that the later a bug is caught in the software development lifecycle, the more costly it is to the business. Automated tests help you to catch bugs earl
