The traditional method of writing unit tests consists of writing the tests in order to check the validity of the code. First of all, the code is written then the tests are written. This is contrary to Test-Driven Development.
Recently, I’ve been asked if Roslyn can be used for helping with writing code that involves preparing mocks with NSubstitute. Of course, my answer was "Yes" but instead of rushing into creating a new project that would implement this functionality, I performed a small research. I checked nuget.org and Visual Studio extensions marketplace, and I discovered that there was a bunch of existing analyzers and extensions that facilitated working with mocks and not only for NSubstitute but for other mocking frameworks, just like Moq or Fake It Easy, too. In this blog post, I will show you how these tools are helping to avoid common problems with mocking and boost your productivity by saving you a lot of typing. Presented examples will be mostly based on the Moq library because it’s my favoring mocking package.
In the past we've thought about records as a feature to enable working with data. "Working with data" is a big group with a number of facets, so it may be interesting to look at each in isolation. Let's start by looking at an example of records today and some of its drawbacks.
In audio programming, you often need to rapidly process buffers of audio. When you record audio, several times a second a new buffer of audio is presented that is usually saved to a file or injected into an audio processing pipeline. And when you play audio, several times a second you are pulling audio out of an audio processing pipeline to provide new buffers to the soundcard.
The ASP.NET team has built a command-line tool called HttpRepl. It lets you browse and invoke HTTP services in a similar way to working with files and folders. You give it a starting point (a base URL) and then you can execute commands like “dir” and “cd” to navigate your way around the API.
