Cleaner tests with XUnit's IAsyncLifetime and expression-bodied members

When writing tests, sometimes it can be tempting to dump a bunch of asserts into the same test to avoid duplication across multiple tests...

Writing Testable Code - It's all about dependencies

Following on from my post about why you should write automated tests, I wanted to talk about how to write code that is testable. Unfortunately, unless you explicitly know how to write testable code, and are familiar with the SOLID principles (which from my experience, the average developer isn't!) - then the natural way we write code, and the way we typically learn to code makes it very hard to write unit/integration tests against our code.

Automated Testing Series - Part 1 - What and Why?

Over the past year or so I've been getting more and more interested in the various forms of automated testing. I've been a developer for verging on 20 years, and yet it's only been these past few years where I've seen a much larger interest in automated testing in the industry as a whole. It's obviously been around for a while, but it's never been as popular as it is today. Especially now the tools and libraries are getting better and better. In the past, it was a rare exception where a developer would heavily write tests as part of their code. Now, it's frowned upon if you don't.
