[Notes on the Talk]

Solving problems in the Test Workflow

The Work

• implementing pr workflow
• facilitate triage workflow
• configure and run jobs
• provide insights into project health

Automating Analysis of Build Job Failure

• Blame: that's just the buildcop's job
• Gain: Automate the Game of gettting green PRs

Ends up in frustrating situation where you check-in build and it fails and only buildcop can solve

Prow Objectives:

• checks conventions (coding standards)
• make sure it builds!
• pass unit and integration tests
• pass e2e tests
• perf tests (using simulation cluster with kubemark)

Code Review (PR Flow Improvements)

• solve problem for knowing how to ask for a Review
• critiques on CODEOWNERS file
  • assigns to all people who match that regex for that file So improve OWNERS file to look and choose selectively
• reviewers
• approvers
• labels

Github Labels

The project CANT live without them.

ALWAYS BE MERGING

• MERGE Commit must pass Test
• 25% flake expected. (Test is 75% Consistent)
• Testst N PRs at once (batch them, maintain velocity)

ISSUE TRIAGE

• /retest command saves time by only running failed jobs
