Windows 8 Unit testing: Include files in your test project

What can I say? Unit testing Windows 8 applications is a painful experience. It’s hard to apply mocking and some stuff is not easy to discover.

Last week I created a Windows 8 unit test that required a specific file to be available on the file system. So I added the file to my test project, changed the Build action to content and set Copy to output directory to Copy always.

But now the hard part what code should I use to read out the file from the file system?

var folder = Package.Current.InstalledLocation;
var stream= folder.OpenStreamForReadAsync("Filename.txt")
view raw Win8ReadFileFromInstallLocation.cs hosted with ❤ by GitHub

That's it. Once you found it, it's actually not so difficult.

A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try!

Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
