We just shipped Core Framework v3 4.0.0-pre.33, Analyzers 2.0.0-pre.9, and VS Adapter 4.0.0-pre.3.

This prerelease build adds support for Native AOT, in addition to bug fixes.

I have an older legacy project where integration tests isn't set up and would be quite complex to do, so using "unit tests" mechanics via substitutes and executed call checks - it works, but a bit cumbersome to write and maintain, but still loads better than manually testing complex import flows.

Finding a failing test 🚨, coming back from the ☕️ break, feels just so ✅ .

- I know where I left off
- I know what to continue with
- I get back into the flow within seconds
- no need to search and analyze the git history
- it 💡 enlightens me and lets me continue where i left off

also when doing hashtag#PHP 😎

God, LLM's write the weirdest and worst unit tests. Why do I gotta review this slop.

#LLM #unittest

I was about to request jokingly an assertRoughlyEquals() method in #phpunit to avoid errors like "Failed asserting that 5.656000000000001 is identical to 5.656" when testing with floats.

Then I realized it already exists ! 😂

Handy !

Code review complete. Time to merge.

New option coming for the xunit3 template: "--native-aot".

This will only be available for C# projects, since Native AOT is only implemented for C#. #DotNet #UnitTest #NativeAOT
