XUnit.V3 compatible version for MTP 2.0.0 · Issue #3416 · xunit/xunit

We are currently updating to MTP 2.0.0 for one of our testing extensions. Since we are using xunit.v3 across our whole code base, we need a compatible version of xunit.v3. Otherwise we run into the...

Just a reminder that we have delayed plans to support MTP v2. Any attempt to use any parts of MTP v2 with xUnit.net v3 will result in failure due to incompatibilities.

Not really. The fundamental collision appears to be in the fact that we always support MTP vs other frameworks that "mix in" support at build time, combined with changes coming to how `dotnet test` works in .NET 10, plus restrictions put into the design of MTP v2.

Too much for a medium like this.

We have unlisted the 3.2.0 preview (MTP v2) packages on NuGet. The documentation pages are still alive (though no longer linked) on the web site, though we will be deleting them at some point.

We are delaying our support for Microsoft Testing Platform v2 due to some technical limitations when interacting with .NET 10 SDK.

We will still support for targeting .NET 10 with our templates before it ships.

We just shipped Core Framework v3 3.2.0-pre.5.

This is specifically for users who wish to try the preview of Microsoft Testing Platform v2. Estimated RTM for 3.2.0 will be close to .NET 10 RTM.

3.1.0 RTM will be later this month.

Given that xUnit.net runs tests in random order by default, would changing the randomization order (in order to fix a bug) just be considered a bug fix or a breaking change?

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 V...

We are hopeful that someday Microsoft shares the private bits of DocFX that they use to make their API site seamlessly support multiple API versions, because the hacks we've had to do are pretty ugly.

FYI, we evaluated integrating api.xunit.net into the new site but it honestly made the main site performance not great due to the size of the TOC, and we wanted to retain the left nav filtering experience. As such, they're going to remain separate.

In preparation for publishing v3 3.0.0, we've switched over to the new website at xunit.net (and new.xunit.net is no longer published).

The new content lives at github.com/xunit/xunit.... (the old `gh-pages` branch of xunit/xunit will be deleted soon).

Let us know of any issues with the new site!

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).

We updated the API documentation pages to include a version home page which includes a list of commonly used types. api.xunit.net

What do you think about the type list? Things you would add/remove?

A prototype of the new web site is live at new.xunit.net. The only thing missing from this is integrating the API content, which we're working on before we ship 3.0 (at which point we'll have the new site live).

Please poke and prod and let us know what's broken!

If we make more breaking changes, we'll ship another prerelease build to NuGet (with release notes & an announcement) and then reset the clock for the final build.

xUnit.net @xunit.net · Jun 8

In concert with `3.0.0` now becoming the `main` branch, you should only expect another NuGet prerelease build if there end up being more breaking changes. Otherwise, we will plan to ship a final `3.0.0` build on our normal schedule (about a month from now).
