Allow exporting state during e2e tests (#7860) 
As of #7663, an in-memory store was used in place of local storage
during e2e tests, to facilitate the use of state fixtures. However,
this made it difficult to export state during a test run. The
instructions for exporting state to create fixtures assumed that local
storage was being used.

A new global function has been added to the background context to allow
exporting state. This method is available during testing and
development, and it works with either local storage or the in-memory
store. The fixture instructions have been updated to reference this new
function.

End-to-end tests

This directory contains the fixture data used to bootstrap the individual e2e tests. Each sub-directory contains one thing:

  1. A state.json file that represents a the saved state for the extension (see Generating fixture data below)

Generating fixture data

Fixture data can be generated by following these steps:

  1. Load the unpacked extension in development or test mode
  2. Inspecting the background context of the extension
  3. Call metamaskGetState, then call copy on the results

You can then paste the contents directly in your fixture file.

copy(await metamaskGetState())
