1656636 - Test which JS modules and components are loaded during subframe content process startup

Status: RESOLVED FIXED

(Core :: DOM: Content Processes, enhancement, P2)

Description

[Nika Layzell [:nika] (ni? for response)]

With Fission, not all content processes contain toplevel content documents, and may only contain remote subframes. We should have a test for which JS modules and components are being loaded when loading a remote subframe, in addition to our existing tests for a toplevel document.

Attachment: Bug 1656636 - Part 1: Add a test for scripts loaded during subframe process startup,

This should help us catch loads of JSActors which may be necessary for toplevel
document loads, but which need not be loaded within a remote subframe.

Attachment: Bug 1656636 - Part 2: Load a real http URI in browser_startup_content,

This avoids missing scripts which are filtered to not load on about:blank
documents.
