I noticed that a version 1.146.2 of the VS Code extension was released a few days ago. Is there a summary of what’s updated?

I’m still pinning myself to 1.127.2, since the version after that broke test-running (see [VS Code won't run tests anymore](https://discourse.julialang.org/t/vs-code-wont-run-tests-anymore/129233)). If that’s supposed to be fixed now, I’ll try the new version.

I tried out the 1.146.2 release today, so far it seems like it’s fixed the testing bugs from 1.140.

I spoke too soon, I’m seeing hangs again. At least this time there are some errors in the “Test Tesults” panel - starting out like so:

So I’ll be reinstalling 1.127.2.

Hm, that actually looks like a Julia bug to me… What Julia version are you using?

Also, there is a newer version of the extension as a pre-release out right now (v1.147) and in general I’m pushing out new versions there a lot that fix more and more test item stuff, its the thing I’m focused on right now. So maybe ideally at the moment try the pre-release versions to get the latest test item fixes. But I don’t think your error would be explained/fixed by the newer version…

I’m using `1.10.9+0.aarch64.apple.darwin14` for my project, but I think VS Code is finding `1.11.5+0.aarch64.apple.darwin14` on my machine and using that for the test daemon processes? I’m not quite sure how to tell.

**[EDIT]** Actually I see `Logging ~/.julia/juliaup/julia-1.10.9+0.aarch64.apple.darwin14` in the error output, so I guess it’s using my `juliaup` default of 1.10.9.

It will always use the Juliaup `release` channel for the coordinator, and then whatever you configured as the default in Juliaup to run the actual tests.

Could you try to run the tests with Julia 1.11 as the default? If this is indeed a Julia bug, maybe it has been fixed in the meantime…

I didn’t get a chance to try Julia 1.11, but I did see that version 1.149.2 of the extension was released in the meantime - I installed that and have put it through a few paces (still with Julia 1.10) and so far it looks good.

I’ve now had a chance to try Julia 1.11 with version 1.149.2 of the extension. Still getting trouble. A test run is currently hung up before executing any tests. I captured the following from the “Julia Test Item Controller” output:

I had also started to see hanging with Julia 1.10, which is what prompted me to try 1.11.

@Ken_Williams I just published pre release version v1.150 of the extension, can you try again? I fixed at least some of the earlier bugs that you showed there, unclear whether that will get rid of the problem entirely.

Thanks @davidanthoff , I’ve installed the latest pre-release (1.152.1 now) and I haven’t put it through a ton of paces yet, but it seems to be behaving well so far. I do like the free-order execution of unit tests, that seems to get big sets of tests running more quickly overall.

I’ll keep it installed and report back if I’m hitting any problems, thanks for the ping.

Well, bummer - I encountered a hang today, so I’ll revert again.

I launched unit tests, went away for a little while (because I knew it would have to re-precompile, I made a change to a `struct`), and when I came back I discovered it was still trying to kick off tests (taking \> 2500s, tests usually take anywhere from 5s to 120s depending on precompilation):

 ![Screenshot 2025-07-21 at 11.16.25 AM](https://global.discourse-cdn.com/julialang/original/3X/0/5/056e9deea964f79da2d4d163f16d535661101527.png)

In the `Julia Test Item Controller` tab I see a few errors:

Additionally, after I quit VS Code I see a bunch of these `testserver_main.jl` processes hanging around and I need to kill them manually:

@davidanthoff I think when I get into a hung state, it has something to do with old test processes hanging around, maybe? It seems to happen more when I run tests, then go away for a while, come back, and run tests again. I see in the Test Results output several messages like this:

```julia
[ Info: Julia test item process launching
[ Info: Julia test item process launching
[ Info: Julia test item process launching
[ Info: Julia test item process launching
[ Info: Julia test item process launching
[ Info: Julia test item process launching
[ Info: Julia test item process launching

```

which is surprising because I thought those processes had already been started previously.

In the terminal, if I do `ps auxww | grep 'ju[l]ia' | less -S`, I see this:

```

Two things to notice: 1) the `100.0` at the top is in the `%CPU` column, so something’s not happy in that process. 2) there are roughly two start times (`STARTED` column) in the data, 4:47PM and 4:59PM. 4:47 is the first time I ran tests, 4:59 is the second time.
