Running MsTest unit tests for your .NET Core code

To be able to run unit tests for your .NET Core code, Microsoft created a new version of the MSTest Framework with support for .NET Core. This version is still in preview yet but provides both testing support from the commandline(through dotnet test) and through Visual Studio.

To get up and running I followed the steps as described here: https://github.com/dotnet/docs/blob/master/docs/core/testing/using-mstest-on-windows.md . However when I tried to run the tests, the Test Explorer in Visual Studio remained empty and no tests were discovered.

What went wrong?

I made a stupid mistake as I only added the MSTest.TestFramework NuGet package. This package contains the Test Attributes and Assertions. To be able to run the tests you also need a Test Adapter and test runner which are part of the dotnet-test-mstest NuGet package. After adding this package, my tests were finally discovered. Problem solved!

From the project.json:

"dependencies": {
   "dotnet-test-mstest": "1.1.2-preview",
   "Marten": "1.2.4",
  "MSTest.TestFramework": "1.0.8-rc"
},

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. 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...
