dotnet test support for MTP

Youssef1313 · 2025-03-27T18:11:20Z

For me I'd like to add dotnet test support for Microsoft.Testing.Platform under CLI. Conceptual docs. A small brief like:

## Microsoft.Testing.Platform (MTP) as first-citizen in `dotnet test` CLI

In .NET 10 Preview 3, `dotnet test` now has a native experience towards [Microsoft.Testing.Platform](https://aka.ms/mtp-overview), which you can opt-in by using `dotnet.config` file as follows:

```toml
[dotnet.test:runner]
name = "Microsoft.Testing.Platform"
```

For more information, see [Testing with `dotnet test`](https://learn.microsoft.com/dotnet/core/testing/unit-testing-with-dotnet-test), which explains how Microsoft.Testing.Platform used to work with `dotnet test` in .NET 9 and earlier, and why a new `dotnet test` experience is needed.

## Microsoft.Testing.Platform (MTP) as a First-Class Citizen in `dotnet test` CLI

Starting with .NET 10 Preview 3, `dotnet test` now offers a native experience towards [Microsoft.Testing.Platform](https://aka.ms/mtp-overview). You can enable this feature by adding the following configuration to your dotnet.config file:

 ```toml
 [dotnet.test:runner]
 name = "Microsoft.Testing.Platform"

For more details, refer to [Testing with `dotnet test`](https://learn.microsoft.com/dotnet/core/testing/unit-testing-with-dotnet-test), which explains how Microsoft.Testing.Platform was integrated with `dotnet test` in .NET 9 and earlier versions, and the reasons behind the new `dotnet test` experience.

What do you think of this?

nit: a native experience for Microsoft.Testing.Platform

@DamianEdwards do you want to do a blurb for dotnet run foo.cs, or would you like me to do that when I tackle my own blurbs?

DamianEdwards · 2025-03-31T14:51:42Z

I don't want to announce until P4+ as it's missing some key features in P3.

baronfel · 2025-03-31T14:54:45Z

thanks - noted that on my list.

baronfel · 2025-04-02T16:04:51Z

First draft up - @nohwnd want to spot-check the test section? @dsplaisted for SDK-related words as well.

@Youssef1313 / @mariam-abdulla did you manage to merge the change that understands the new format without the :? I saw remarks about the change being in preview4 in multiple places.

does the :-based impl work? I'm concerned with putting something in the p3 relnotes and then changing it in p4 - folks often just google and copy-paste.

: violates TOML and is going to P3. Unfortunately, we already documented it and it's shipping in P3.

@Youssef1313 / @mariam-abdulla did you manage to merge the change that understands the new format without the :? I saw remarks about the change being in preview4 in multiple places.

Yes the change was merged.

I would rather just not talk about the non-compliant feature in p3 if a fix and future-forward version is coming in a month. Similar logic to what Damian was saying with regards to dotnet-run singlefile. You get one chance to make a first impression - it should be correct and complete.

@baronfel So you mean drop it from release notes?

We have had it documented in dotnet/docs repo though and have seen few users playing with it already on Preview 2 😕

Yes the change was merged.

I meant merged in code that will be released in preview3.

I assume "Microsoft.Testing.Platform" would NOT work with preview3 right?

reverted to the working p3 form.

"Microsoft.Testing.Platform" should work with preview 3.

edit: actually fixed the things - Microsoft.Testing.Platform and dotnet.test:runner for p3
