checkReportJson function

String checkReportJson(List<MetricCheck> rows)

Machine-readable verdicts of one run's checks, keyed for consumers (the action's PR-comment step renders the regressions rows).

Implementation

String checkReportJson(List<MetricCheck> rows) {
  final regressions = rows.where((r) => r.regression).toList();
  return jsonEncode({
    'ok': regressions.isEmpty,
    'regressions': regressions.length,
    'metrics': [
      for (final r in rows)
        {
          'metric': r.metric,
          'ref': r.ref,
          'measured': r.measured,
          if (r.golden != null) 'golden': r.golden,
          'status': r.regression
              ? 'regression'
              : (r.noGolden ? 'no-golden' : 'ok'),
          if (r.deltaPct != null) 'deltaPct': r.deltaPct,
        },
    ],
  });
