The trade-off is the window, which is limited by the retention of the logs (90 days, by +default). + +## What the dashboard reports + +For the analyzed window: + +- which tests were reported as failing, how often, in how many different job configurations, and + when they were last seen; +- which of those failures were **recovered on retry**, in other words: proven flaky; +- which job configurations failed, and how often - a job that fails without any test failing is + usually an environment or a timeout problem, and that is worth knowing too. + +Occurrences are counted per (commit × job configuration × outcome × top-level test), so a single +bad job execution counts once, and subtests do not inflate the ranking of their parent. + +## Emitting + +The two halves talk to each other through one marker line per test, written to the job log: + +``` +flaky-test-dashboard: failing TestFoo +flaky-test-dashboard: flaky TestBar/subtest +``` + +| Class | Meaning | +| --- | --- | +| `failing` | Failed, and never passed - even on retry.

Flaky beyond a doubt. | + +The same two classes are also emitted as GitHub Actions annotations (`Failing tests` as an +error, `Flaky tests` as a warning), which is what shows up on a pull request. The collector does +not read those: annotations cost one API request per job, markers cost none, since the logs of a +whole run come in a single archive. + +`flaky-annotate.sh` derives both classes from a `gotestsum` json file, so the retry information +is only there if the tests were actually retried (`--rerun-fails`): + +```yaml +- name: "Run: tests" + run: | + gotestsum \ + --jsonfile=/tmp/tests.json \ + --rerun-fails=2 \ + --post-run-command ./mod/soigneur/flaky-annotate.sh \ + -- ./... +``` + +It can also be called as a plain step (`flaky-annotate.sh /tmp/tests.json`), and it writes the +two lists to `SOIGNEUR_FAILING_OUT` / `SOIGNEUR_SOIGNEUR_OUT` for callers that render their own job +summary.

A busy week of a single +branch measures at roughly 100 runs, so 200 requests and 50 MB, against the 1000 requests per +hour and per repository that the `GITHUB_TOKEN` of a workflow gets. + +The per-job alternative, reading the annotations through the checks API, costs one request per +job execution instead - about 800 requests for the same week, uncomfortably close to that limit, +which is why the markers in the logs are what gets collected. The annotations remain, for the +humans. + +Note that the logs are the only thing that can be read back: GitHub's job summaries are not +exposed by any API, only rendered in the web UI from signed attachments. + +The downloaded logs are whole job logs, written to a temporary directory that is removed when the +report is done - unless `SOIGNEUR_WORKDIR` is set, in which case they stay there. GitHub masks the +registered secrets in the logs it archives, but a log still holds everything else the run +printed, so do not upload a workdir as an artifact. + +The test names, too, come out of those logs, which means they are only as trustworthy as what the +tests printed: a test that prints a line shaped like a marker gets it collected. The collector +therefore keeps only the names that can plausibly be a Go test name, and the renderer escapes +what ends up in the tables, so that a crafted name cannot turn into a link, or into markup, in +the issue. + +## License + +Apache License 2.0.
