Can’t you use a free version of one of the Jetbrains IDEs? Jetbrains test runners and debug are great.
I have all the all products pack which is about $150/yr(?), which is not many hours work.
Pretty much all editors have the LSP so I don’t think there are huge differences between the popular ones. If you’re old use Emacs, if you’re cool use vim, if you’re a numpty use vscode, if you are rich use Jetbrains.
