"Microsoft Testing Platform is cool!" by Tomasz Cielecki https://blog.ostebaronen.dk/2025/07/ms-test-platform-is-cool.html #DotNet #UnitTest
Cheesy bits and bobs · Microsoft Testing Platform is cool!I love xUnit and I use it for most of my testing. With xUnit v3 the possibility of running the tests was added without the need of using any other external tools like console runners, dotnet test or VSTest. So a xUnit test suite is just a executable itself. Not long after xUnit v3 were released I discovered Microsoft Testing Platform, which achieves something very similar. According to their own docs it “[..]is a lightweight and portable alternative to VSTest for running tests in all contexts”.
Using #claude to write #flutter #unittest code in a single sit down session.
Without no logical edits and only sparse missing imports and only a single #aihallucination (a made-up foundation class) it easily achieved >50% pass/fail and >70% #coverage.
Impressive or not?
EDIT: And, yes, this absolutely included reading/code-reviewing all generated code before running the tests.
We just shipped Visual Studio adapter 3.1.3.
This is a bug fix release to address a failure case when running xUnit.net v2 tests (which was introduced in 3.1.0).

We just shipped a new prerelease build of the core framework (3.0.0-pre.40).
There are no new breaking changes, so this will not reset our release clock for 3.0.0 (which should be in about a week).

Continued thread
Just a reminder that we only have roughly 10 more days of before we ship 3.0. If you've been putting off validating your tests and/or extensions with the latest prerelease, your time is running low...
{testthat} is great for automatic testing. Here are some tricks for the heavy user: https://blog.r-hub.io/2020/11/18/testthat-utility-belt/ #rstats #testing #unittest #testthat
blog.r-hub.ioHelper code and files for your testthat tests - R-hub blogIf your package uses testthat for unit testing, as many packages on CRAN, you might have wondered at least once about where to put “things” you wished to use in several tests: a function generating a random string, an example image, etc. In this blog post, we shall offer a round-up of how to use such code and files when testing your package.
Code called in your tests
Remember our post about internal functions in R packages? What about internal functions in unit tests of R packages? And code that needs to be run for tests?
We just shipped a new prerelease build of the core framework (3.0.0-pre.25).
This includes new breaking changes since last week's prerelease. Please check the release notes for more information.

Thinking about what an AOT version of @xunit would look like. I spent some time talking to @agocke last year about it so I have some thoughts.
It almost surely end up being a completely separate code base/package. No mixing and matching, because the internal design would be very different.
Top three things I think:
- .NET 8+ only (no .NET Framework)
- C# only (no F# or VB)
- No extensibility points (you get our Fact and Theory, you get our pipeline).

We'd like to get some feedback on a change coming in 2.0.0 for Assert.Equal displays when doing collection comparisons. We've already made a change to make string comparisons better, but should we do it for all collection values?
Goodbye Michael Foord.
You will be missed.

It's release day! 
We just shipped v2 Core Framework 2.5.0, Analyzers 1.2.0, and Visual Studio adapter 2.5.0. This release includes a bunch of quality of life improvements, bug fixes, and an overhauled assertion library that includes new assertions, new overloads, and much better (and most consistent) assertion failure messages.
Enjoy!
