🚀 v13.20.1 Testing & Release Quality Process

Hi Team,
As part of our new MetaMask Release Quality Process, here’s a quick overview of the key processes, testing strategies, and milestones to ensure a smooth and high-quality deployment.

📋 Key Processes

Testing Strategy

Developer Teams:
Conduct regression and exploratory testing for your functional areas, including automated and manual tests for critical workflows.
QA Team:
Focus on exploratory testing across the wallet, prioritize high-impact areas, and triage any Sentry errors found during testing.
Customer Success Team:
Validate new functionalities and provide feedback to support release monitoring.

GitHub Signoff

Each team must sign off on the Release Candidate (RC) via GitHub by the end of the validation timeline (Tuesday EOD PT).
Ensure all tests outlined in the Testing Plan are executed, and any identified issues are addressed.

Issue Resolution

Resolve all Release Blockers (Sev0 and Sev1) by Tuesday EOD PT.
For unresolved blockers, PRs may be reverted, or feature flags disabled to maintain release quality and timelines.

Cherry-Picking Criteria

Only critical fixes meeting outlined criteria will be cherry-picked.
Developers must ensure these fixes are thoroughly reviewed, tested, and merged by Tuesday EOD PT.

🗓️ Timeline and Milestones

Today (Friday): Begin Release Candidate validation.
Tuesday EOD PT: Finalize RC with all fixes and cherry-picks.
Wednesday: Buffer day for final checks.
