Snippets in VS Code test framework

Tooling
1

Hi,

I’m trying to update my package to use the new VS Code test framework. In my runtest.jl file, I have:

@testsnippet MySnippet begin
    A = [1 2; 2 4]
end

@testitem "LinModel construction" setup=[MySnippet] begin
    @test A == [1 2; 2 4]
end

if I press on the play button here:

This error is printed in test results:

  Expression: A == [1 2; 2 4]
  UndefVarError: `A` not defined in `Main.var"##233"`
  Suggestion: check for spelling errors or missing imports.

I’m using the Julia Extension v.1.83.2 :

What I’m I missing ?

Your test runs fine on my system. Maybe try updating your packages and VSCode (I’m on 1.97.0).

Thanks for the tips! I first tried to update the julia extension and it was always coming back to v1.83.2. I figured that it was an incompatibility with my VS Code version. And yes my VS Code version was old (june 2024). I updated my VS Code and everything worked after.
