XUnit–Writing test output

I recently started using XUnit. I’m still discovering what is possible using this unit test framework.
One of the things I had to discover was how to write log messages during my tests.  I could fall back to using Trace.WriteLine or Console.WriteLine but that is not the best solution. XUnit allows you to capture test output using a special interface called ITestOutputHelper. In order to use this, just add a constructor argument for this interface and store it inside a variable inside your test class:


Now if you call the ITestOutputHelper.WriteLine method, the output is captured and available inside your test output:

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...
