There is an interesting dichotomy in my life now that I'm retired.

@xunit has always been "the test framework I want to use" and its popularity is secondary. Except, the only thing I use it for now is itself, since it's the only code I write now. So keeping going has, by definition, shifted away from being primarily about the features I want to use in my day job.

When do I just stop? Is there anybody I'd trust with its future? #DotNet #UnitTest #FOSS

🧪 I just released unittest-parametrize 1.9.0.

This package helps you make parametrized tests that work with the grain of unittest, but can still be run with pytest.

This release adds new skip/expected_failure features, fixes a bug when using Coverage.py's dynamic contexts, and tidies up error messages and usage docs.

Do you use .NET Framework with xUnit.net?

If you're still using .NET Framework and you feel comfortable providing the information, we'd love to know what keeps you there (and when you'll stop needing to support it).

RE: https://dotnet.social/@xunit/117097353301454220

One week in, and we're sitting at only a single bug so far. That includes 250k downloads of the core framework, 275k downloads of the analyzers, and 750k (!!) downloads of the Visual Studio adapter.

Anybody using Native AOT? How about full test parallelization? #DotNet #CSharp #FSharp #UnitTest #TDD

@vitest killed Jest

As per the [first graph], we can see :

* the number of downloads of Jest are stable
* the number of downloads of Vitest is increasing fastly

The [second graph] shows the relative decline of Jest compared to Vitest

Looks like unless something dramatic happens, @xunit v3 is hitting 4.0 this week. Time to unleash the fully parallelized power of this space station! (No, seriously though, Native AOT is a much bigger feature in terms of effort.) #DotNet #UnitTest #TDD

🆙 Updated my post on unittest base test cases with a new preferred technique: using a plain class as a container.

UnitTesterJS: Lightweight Unit Test Runner for Javascript

Runs test functions while keeping track of failures, logging them and to provide a summary. No dependencies, runs in the browser too. Works well with chai.

new in 2.1.0:
- Adds small PromiseStatus helper to inspect the state of promises and avoid some try/catch when testing for rejected promises.

features: https://docs.miamao.de/@main/unittesterjs/?#features-and-configuration

How do you #unittest your #sql ?

Un moyen de faire tourner des tests unitaires avec des vraies dependences (base de données, etc.) plutôt que des mocks, grâce à des containers légers.

There will be another prerelease of @xunit, presumably this weekend. A remarkable amount of stuff arrived over the past few weeks (though thankfully not very many bugs) that I really want to get in. I'd also really like to see whether ttps://github.com/xunit/xunit/pull/3581 can land for 4.0, because more flexible parallelization options has been a long-requested feature. #DotNet #UnitTest #CSharp

I know I'm a geek - but there's a certain degree of satisfaction in having a test made to fail after a refactoring actually fail as expected and then implementing the fix as expected.

And to imagine some people want to offload that satisfaction to a LLM tsk tsk tsk.

#developer #test #unittest

We just shipped Core Framework v3 4.0.0-pre.108 and Analyzers 2.0.0-pre.51.

This release adds new features, new analyzers, and fixed several bugs. We anticipate these being the final prerelease builds of this cycle. Please test thoroughly!

There will be another prerelease coming this weekend.

Since we like to have prerelease builds stable for a month before declaring them release, please make sure to use the current and upcoming builds to verify, especially with Native AOT.

Thanks!

Based on this poll, we will be removing support for Visual Studio 2019 and out-of-support versions of Visual Studio 2022 from `xunit.analyzers` sometime before the final 2.0.0 release.
