Github Actions Pipeline - run unit tests as PR validation and on demand

[razvangoga]

• [x] new github actions pipeline for continuous integration
• [x] runs on demand
• [x] runs as a mandatory check for all PRs

general notes

• moved all old MS CI / build stuff to .old-ms-ci folder
• removed the MS Arcade project build configuration in favour of vanilla dotnet commands (build / test)
• CI build pipeline is in https://github.com/tye-v2/tye2/blob/feature/7-ci-pipeline/.github/workflows/ci.yaml

on linux agent

• almost all tests are green : 203 / 209

• the red tests are due to host.docker.internal not being accesible in the linux variant of docker
  • https://github.com/docker/for-linux/issues/264
  • https://stackoverflow.com/a/43541732/45091
  • even aspire has a workaround for this : https://github.com/dotnet/aspire/blob/main/src/Aspire.Hosting/Utils/HostNameResolver.cs
• i've disabled the red tests for now (by adding a xUnit trait for them and filtering them out based on it):

on windows agent

• the windows agents are only partially usable because they seem to use the Windows Container version of Docker Desktop => any linux only container image (ex Redis for Dapr) is not usable on it

macos agents

• the run minute for a macos agent is 10x as expensive as a linux one 👎
• does not come with Docker Desktop installed and the installation takes a lot of time

When running as PR check the test results are published in the PR thread

Great Job!

Regarding agents, what do you think would be future approach, because we need a pipeline to release Tye2 especially on Windows and also macOS?

[razvangoga]

for the release i think all agents should work - most of my problems with the windows and macos have to do with the docker instance on them (or lack thereof).

for pack and push we only need the source code and the dotnet sdk
