Hello,

We're interested in moving to swift-testing for our cross platform project, so we can take advantage of consistent tests across our Mac, Windows and Debian CI bots (via SPM). Im seeing conflicting info though on requirements to implement this. Are these still supported only via swift 6 nightlies? Or can they be run from the current swift 5.10 releases on Windows and Linux?

Thanks,  
Mike

Hi @mikewoodworth, please see the documentation updates we landed in [#466](https://github.com/apple/swift-testing/pull/466) as well as my [Forum post](https://forums.swift.org/t/an-update-on-swift-testing-progress-and-stable-release-plans/71455) from a couple months ago. Swift 6 development snapshot toolchains are required to build swift-testing now, and our intention is to release the first stable version in alignment with Swift 6.

If you've seen conflicting information, please let us know where, so we can try to correct that! It's possible we overlooked some places that need to be updated.

I'm kinda confused to make it work on Linux (Ubuntu 22.04), currently getting

```swift
error: compile command failed due to signal 9 (use -v to see invocation)
error: fatalError

```

Swift version is installed via Swiftly as `main-snapshot` (I have also tried `6.0-snapshot`, but it fails to find `PackageDescription` for some reason):

```swift
Swift version 6.0-dev (LLVM 65ce91c9f45183f, Swift 4ce62af5a0b5e6b)
Target: x86_64-unknown-linux-gnu

```

The project I'm trying on is simple as possible:

- Create new package with `swift package init`
- Add `swift-testing` as dependency from `main` branch
- Update initial test file to be

```swift
import Testing

@Suite
struct DemoTests {
    @Test
    func sample() {
        #expect(true)
    }
}

```

- run `swift test`

I assume it fails to compile SwiftSyntax for some reason, but can't understand what's wrong: toolchain? branch? else?

Have you tried passing `-v` as suggested by the error message, to pinpoint the exact command invocation that crashed?

Yes, the latest command before the crash:

I've figured it out: memory issue. All the machines I have available have been using too few memory, so building just got stuck and killed eventually by the system. Adding swap has fixed build process. Thanks for jumping in anyway, it made me re-evaluate reasons again.
