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"
},

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

VS Code Planning mode

After the introduction of Plan mode in Visual Studio , it now also found its way into VS Code. Planning mode, or as I like to call it 'Hannibal mode', extends GitHub Copilot's Agent Mode capabilities to handle larger, multi-step coding tasks with a structured approach. Instead of jumping straight into code generation, Planning mode creates a detailed execution plan. If you want more details, have a look at my previous post . Putting plan mode into action VS Code takes a different approach compared to Visual Studio when using plan mode. Instead of a configuration setting that you can activate but have limited control over, planning is available as a separate chat mode/agent: I like this approach better than how Visual Studio does it as you have explicit control when plan mode is activated. Instead of immediately diving into execution, the plan agent creates a plan and asks some follow up questions: You can further edit the plan by clicking on ‘Open in Editor’: ...
