[Epic] Detox 20 Breaking Changes

[d4vidi]

Description

This is a meta-PR to put miles with all the planned major and breaking changes and roll them out when ready.

Implemented:

• Jest-Jasmine and (older) Jest-Circus deprecation in favour of a newer implementation  #2469
• feat(config): drop default "e2e" value for specs #3289
  • check specs docs, because the feature looks historically underdocumented... 🤔

• [Detox 20] Boot Android emulators in read-only mode by default #3539
• JS: set required Node.js version to be >=12.10.0 82c0e7a
• feat(iOS): open the Simulator app by default. #3304
• feat: drop Mocha support #3310
• docs: update Xcode debugging guide #3326
• Remove deprecated native IdlePolicyConfig #3332
• JS: retire appLaunchArgs { permanent: boolean } signature #3352
• JS: Retire ios.none driver (succeeded by behavior: 'manual') #3349
• JS: Remove legacy config syntax (kebab-case) #3355
• JS: Drop heavy legacy config support #3351
• Drop support for old Jest versions (<27.2.5) #3394
• Research to what extent we can switch to globalSetup/Teardown #3397
• [Detox 20] JS: migrate to jest globalSetup, globalTeardown configuration #3354
  • feat(api): Detox Internals
  • feat(api): Logger
  • feat(config): testRunner section
  • feat(config): logger section
• [Detox 20] Genymotion SaaS guide #3584
• [Detox 20] Documentation: migration guide, API updates #3572
• Facilitate testing React Native apps in debug mode on Android #3494
• [Detox 20] Unit tests gap #3585
• [Detox 20] Code Review #3638

Planned:

Postponed

• JS: Undeprecate device.relaunchApp() #3350 (re-deprecated in 9e840b6)
• [Epic] DAS Phase 1: Global device allocation #3573
• [Genymotion SaaS] Remove Genymotion jar (use artifactory) #3353
• Android: Usage of ActivityTestRule instead of ActivityScenarioRule – @d4vidi says that due to the planned multiple apps breaking change, we need to postpone it – otherwise, users will need to fiddle with Android files twice every migration.
