CT Stack Traces

[sync-by-unito[bot]]

Summary

In E2E we show a stack trace if there is an error in the test. It is (5) here:

!image-2022-02-09-20-16-55-107.png|thumbnail!

We want the same thing for CT. Right now, webpack dev server does not supply the correct source map - in fact, it doesn't have one at all. Also, even if it did, the seam between the dev-server and CT runner is not set up for stack traces.

For CT we go here https://github.com/cypress-io/cypress/blob/10.0-release/packages/driver/src/cypress/script_utils.ts#L49 as opposed to E2E which goes on and calls this https://github.com/cypress-io/cypress/blob/10.0-release/packages/driver/src/cypress/script_utils.ts#L36 which gets the source map.

Acceptance Criteria

• Should return the source map from webpack dev server
• Should extract and display it for component testing

I have some OOO coming, and expect to have to pick up some other things while working on this, so opening this PR early just to give visibility to my work.

Do source maps for the vite-dev-server work? Or is it just webpack-dev-server?

[lmiller1990]

Not sure, but I'm guessing source maps are a pre-requisite for correct and accurate stack traces.
