Test upgrade on the Beta channel

[bsclifton]

When development is complete, we should test the Muon to Brave Core upgrade path officially on the Beta channel of browser-laptop. This issue is basically the test plan for brave/browser-laptop#15309

An in-depth explanation of how the upgrade happens can be found here:
#1863 (comment)

There is also a support article (which we link to). Details about that can be found here:
#1918

Pre-testing steps

• Release brave-core with --upgrade-from-muon that imports all expected data
• Package final brave-core release channel binaries in browser-laptop
• Build new version of browser-laptop and push to beta channel

Test plan

• Does upgrading to this new version of Muon install Brave Core? (Windows Automate the install of brave-core (Windows) #1540, macOS Automate the install of brave-core (macOS) #1541)
• Does the install of Brave Core happen silently? (Windows Test Windows installer for brave-core; ensure silent install possible #1538, macOS Test macOS installer for brave-core; ensure silent install possible #1539)
• Does Muon pass the --upgrade-from-muon flag to Brave Core when it launches (verifiable via brave://version, under Command Line: - Launch brave-core after it is silently installed #1543)
• Does Muon have a new icon? (Create a new icon for Muon Brave to show its deprecated #1915)
• If you uninstall Brave Core and relaunch Muon, it should NOT re-install Brave Core (browser-laptop should only attempt brave-core install once #1911)
• After the upgrade, if user launches Muon, there should be an ugly warning on new tab page and a link to a support article. New tabs will ALWAYS show this (Show a notice about how browser-laptop is deprecated #1544)
• Is sync disabled? You should be able to restore existing groups and (if you have a group) clear the associated data. But you can't create groups. (Hide sync in Muon #2303)

Windows specific

• Does stub executable on Windows open Brave Core? ex: if set as default browser, double clicking an HTML file should open Brave Core (Update stub executable for brave/Squirrel.Windows  #1782)
• Is there an “old” shortcut which does launch Muon? (in case someone wanted to see their reports, etc - Ensure a shortcut is created for launching browser-laptop #1867)
• Do Add / Remove Programs and Default programs (Windows 10, where you set default handlers) show Brave (old) for Muon? (Polish the Windows upgrade experience #1916)
• Uninstalling Muon Brave on Windows should keep the stub executable in place (meaning user doesn’t have to change default browser, if it was Muon - Uninstall of Muon Brave on Windows should leave behind the stub executable #1912)

Linux specific

• When user upgrades (via apt, yum/dnf, etc), Brave Core will not install
• When user upgrades to latest Muon, there are warnings shown in notification bar and on new tab page (In-app experience for Linux should make it obvious that Brave is deprecated #1917)

Import test plan

These can't be tested yet, because the Brave Core components aren't finished (yet)

• When Muon installs Brave Core and launches, does it import all important data (stats / bookmarks / cookies / passwords / brave payments / etc - When a user of today's Brave updates to Brave Core, all data should be imported automatically (without prompting) #872)

Known use-cases

Here are the known use-cases and how they work:

• User is prompted for update on Muon. They hit “Update” to relaunch Brave OR they close it (Either way, we force-relaunch Muon)
• HAPPY PATH
  • user is on macOS or Windows
  • Brave Core is not installed yet (no profile directory)
  • Brave Core will be installed and executed with --upgrade-from-muon
  • Immediately after launching Brave Core, Muon quits (no UI is ever shown to user)
  • --upgrade-from-muon flag is detected by brave-core; import takes place
• NOT HAPPY PATH
  • If user is on Linux, nothing happens
  • If installing Brave Core fails, nothing happens
  • If user already has Brave Core installed, nothing happens (no import)
• DIFFERENT BUT POSSIBLY HAPPY PATH (NEEDS CONFIRMATION)
  • If the user uninstalled Brave Core at some point (ex: they have a profile directory) and then upgrades Muon
• EDGE CASE
  • If user goes through the upgrade process and then decides to delete Brave Core, Muon will not attempt to re-install it

Should we update the users to RELEASE channel (on brave-core)? or BETA? Would be good to respect their channel preference and keep them on BETA if possible

Just finished testing this with the current code for Windows on NIGHTLY channel

• Update found - it was downloaded 😄👍
• Update finished downloading... and then it did the silent install for Brave Core and launched into it? 🙀 (so now, Muon is open saying "Do you want to restart?" and there is a Brave Core window which is now on top of the Muon window)
• Clicking "Restart" on the notification bar in Muon quits and relaunches Muon? 🙀
• Squirrel executable works as expected: 😄👍
  • default browser being Muon launches Brave Core
  • shortcuts to Muon launch Brave Core

Tested:

• Installed 0.25.201
• Ran 0.25.201
  • Prompted for update
  • Prompted for app restart (still only muon showing)
  • Click Restart
    • Muon launches
    • Brave Core launches
      • Quit both
      • Open "Brave Nightly"
        • Brave Core launches

[bsclifton]

Tested on macOS last nite:

• update found; it gets downloaded 👍
• I clicked the Do you want to restart? and it quit as expected 👍
• relaunch happened, no UI is shown. It installs brave-core fairly quickly (since it has the entire installer, not just the stub installer) 👍
• after it does the silent install of brave-core, it launches directly into brave-core 👍

Also tested on Windows:

• same behavior as before
• the Brave (old) shortcut was NOT placed onto desktop. Might be a bug with Updated to generate duplicate desktop (used for old browser-laptop) electron-squirrel-startup#5 (I manually tested using the release channel, not Nightly)?

OK here we go - update pushed to BETA channel

1. Dowload latest Muon BETA if you haven’t already https://github.com/brave/browser-laptop/releases/tag/v0.23.204beta
2. Check for update
3. You should be prompted for upgrade (which will be version 0.25.217)

Looks good! Merged brave/browser-laptop#15309 and we'll be going live here soon
