Disappearing tab in Microsoft Test and Lab Manager

After using Test and Lab Manager for a while, suddenly the Test Results View disappeared after some resizing. We tried everything to get the tab back, but repairing, re-installing, cleaning the registry, nothing did the trick.

Today a colleague finally found a solution. You have to clean the settings stored in the Local App Data section of your user profile. These settings are simple XML files that have your settings from MTLM – window size/location, whether the Test Runner is docked or floating, the queries you’ve configured in Test Case Manager, etc…

To easily navigate to them on Windows Vista, 2008, 7, or 2008 R2, open this folder in Windows Explorer:

%localappdata%\Microsoft\TeamTest\v10.0\

Or, on XP, 2003, and 2003 R2:

%userprofile%\Local Settings\Application Data\Microsoft\TeamTest\v10.0\

In this directory you will see a number of *.config files. They will be prefixed with ‘mtlm’. The main configuration file is ‘mtlm.config’ – the other files you see are isolated files for each of the activities within MTLM.  Just delete all the *.config files in the folder mentioned above. You should do this while MTLM is not open, since we save your settings on exit. Once you’ve done this, you’ll start MTLM in the clean state you had it when you first installed it.

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

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...
