Playwright JSON Import - 2026-10-22

Context

Most end-to-end testing today is Playwright in JavaScript and TypeScript repos. testo ingest and equipment: playwright both read Playwright through its JUnit reporter, which keeps only each test's last attempt. A test that failed and then passed on retry looks like a plain pass, the earlier error is gone, and the traces, screenshots and videos Playwright saved are not linked to anything. Retries and traces are exactly what people debugging a red Playwright run need, and the JSON reporter has all of them.

Decision

• testo_core/reporting/playwright_import.py converts a Playwright JSON report (--reporter=json) into Allure results. The JUnit importer hands it every matched file that ends in .json, so junit_xml globs, testo ingest and the post-stage hook all accept Playwright JSON with no new option. Everything after that point (summaries, history, Compare, testo flaky, reporters) is unchanged.
• One result per test, attempts as steps. Totals count tests, not attempts. Each attempt is an Allure step with its own status, duration, error and attachments, so the Allure report shows what happened on every try.
• Status. Playwright's expected → passed (skipped when skipped), flaky → passed with statusDetails.flaky set and the first failure's message, skipped → skipped, unexpected → failed (broken when interrupted). A timeout is a failure, as Playwright reports it.
• Identity. fullName is file › describe › title [project], so the same test in two Playwright projects is two tests. The project and the attempt count are Allure parameters, @tags become Allure tags.
• Attachments. Traces, screenshots, videos, error-context.md and testInfo.attach() bodies are copied next to the result as Allure attachments. Files are read only from inside the stage's target_repo (for testo ingest, --repo). Playwright writes absolute paths, so a report made on another machine is matched by the tail of each path under the repo, which makes a CI artifact downloaded to a laptop work. Missing, outside or oversized (over 50 MB) files are skipped and logged, never fatal.
• equipment: playwright now adds --reporter=list,json,html and writes the JSON report to test-results/testo-results.json. Its default reports are alternatives: the executor imports the first one that was written (JSON, else test-results/testo-junit.xml for a stage that sets its own --reporter=junit), so the same tests are never counted twice.
• Server uploads. testo ingest --server uploads .json files as they are, and POST /api/v1/ingest keeps the suffix so the server reads them the same way. Attachment files are not uploaded.

Consequences

• Flaky Playwright tests count as passed, like Playwright itself counts them; the flaky flag and the failed attempt are visible in the Allure report. testo flaky still works from history across runs.
• Testosterone's own UI does not show attachments yet. They are in the Allure results, so testo report allure shows them, and Playwright's HTML report stays the run's native report for equipment: playwright.
• Traces for uploaded runs stay on the CI runner. Uploading them would need a size budget on the server; left for later.
• The JSON report can be large for big suites (it includes stdout). It is read once per run.
