Relates: #2326

Description

As suggested here, I added flaky test detection to the Playwright configuration: if the test is failed, it is retried until it is passed (marked as a flaky) or until all 2 retries have been exhausted (marked as a failed).

retries: 2 - count of retries
failOnFlakyTests: true - enables flaky detection.

Test Procedure

1. Run pnpm --filter @roo-code/vscode-webview test:visual
2. If WelcomeViewProvider.visual.tsx failed again, you can notice that now it's marked as flaky test:

Summary

Summary by CodeRabbit

• Tests
  • Automated test runs now retry failed tests twice and fail when tests are flaky. Visual regression checks have a 15-minute time limit, up from 10 minutes. These changes affect automated testing only and do not change application behavior.

The Playwright component-test configuration sets two retries and fails the run when tests are flaky. The visual-regression job timeout increases from 10 to 15 minutes.

Changes: Visual test configuration

Layer / File(s)	Summary
Configure retry behavior webview-ui/playwright-ct.config.ts	The configuration sets two retries and enables failure on flaky tests.
Extend visual job timeout .github/workflows/visual-regression.yml	The webview-visual job timeout increases from 10 to 15 minutes.

Estimated code review effort: 2 (Simple) | ~5 minutes

Full details: Title check

Explanation

The title "chore: add flaky test detection to Playwright" matches the main change. The PR adds retries, isolated retry strategy, and failOnFlakyTests to the Playwright config. The title is short, specific, and uses a conventional commit prefix. The title does not mention the CI timeout increase, which is a minor secondary change and is expected to be omitted.

Full details: Security Boundaries

Explanation

The changes add Playwright retries and flaky-test failure, and extend the visual-test timeout. No changed path shows a secret or PII leak, unvalidated input execution or trust, or an approval or allowlist bypass.

Full details: Description check

Explanation

The description follows the repository template and fills in the main sections: related issue, description of the Playwright retry and flaky-detection change, test procedure with before and after output, and a completed checklist. The Related GitHub Issue section links #2326 using "Relates:" rather than "Closes:", which is acceptable for a non-closing link. The description does not state the retry strategy or the isolated retry setting that the PR objectives mention, and the summary is brief. Those gaps are minor, so the description is mostly complete.

Review status

Thanks for contributing. This comment tracks the review sequence and the next action.

Current step: Address maintainer or CODEOWNER feedback, push an update, then re-request review from the blocking maintainer.

Review-state labels are managed by this workflow; do not edit them manually. community-approved is managed the same way — do not add or remove it manually. It signals a fresh community code approval for the current head as an advisory priority only; maintainer review is still required.

- Line 68: Increase the Playwright CI job deadline configured alongside
`retries` so two workers can complete all visual-test attempts and retries and
upload the report before timeout; preserve the existing retry count.
- Line 68: Add an automated check for the visual test command that deliberately
fails once, passes on retry, and asserts the command exits nonzero despite the
retry succeeding. Keep the check controlled and focused on the existing retry
behavior configured by retries.

Hello! Nice to meet you in this PR's comments!

With failOnFlakyTests: true, does a test that passes on retry still fail the job? In run 42453772004 the report shows Flaky 1, Failed 0, but the webview-visual job ended with failure. If you want CI to tolerate flakes, should this be false? If you want to keep it, could the description say that a flaky test still fails the job?
