Allow navigation between related code, e.g. from test to implementation

[andyw8]

I have checked that this feature is not already implemented

• This feature does not exist

Use case

See below

Description

It's convenient for developers to jump between a test and its corresponding implementation.

(in Vim, Projectionist is a popular plugin for this)

Implementation

A planned VS Code feature may help with this: microsoft/vscode#126932

But it would good to have it available for all editors.

How is this one different than #2665? Can we close one of the two and keep a single issue?

[andyw8]

Ah, I didn't find that when looking.

Let's keep this one as it describes it in a more general way (e.g. for Rails, this is the same mechanism that could power jumping from a controller action to its view).

We should report this as a possible use case in microsoft/vscode#126932 and suggest making go to related code more generic. I might be wrong, but based on the issue's title it looks like they are planning it more as a testing thing rather than a general feature.
