Summary

  • Large suites (e.g. Zeus's ~3000 tests) render a markdown table with one row per test case. That easily exceeds GitHub's GITHUB_STEP_SUMMARY size limit, causing the summary to render nothing at all.
  • When all tests pass (failed === 0), buildMarkdown now emits a compact per-class table (class, test count, total time) instead of one row per test. When there are failures, the existing per-test table (with failure details) is unchanged.

Test plan

  • pnpm check (format, typecheck, tests, build) passes
  • Added a test asserting the all-pass path renders the | Class | Tests | Time | summary instead of per-test rows

Summary by CodeRabbit

  • New Features

    • Added a concise summary table grouped by test class when all tests pass.
    • Summary tables include test counts and execution times, with groups sorted alphabetically.
    • Retained detailed per-test status information when failures or errors occur.
  • Tests

    • Added coverage to verify successful results produce the expected grouped summary.

…asses

3000+ individual pass rows blew past GitHub's job summary size limit,
causing the whole summary to render as nothing. When there are no
failures we now show test counts/time grouped by class instead of one
row per test case; the full per-test table still renders when there
are failures.

Review Change Stack

Walkthrough

buildMarkdown now groups entirely passing results by class and reports counts and durations. Results with failures or errors retain the per-test status table. Tests verify the grouped output and the omission of individual success icons.

Changes

Markdown summary generation

Layer / File(s) Summary
Class summary aggregation
src/main.ts
groupByClass aggregates test counts and execution times by class, falls back to the test name, and sorts summaries alphabetically.
Output selection and coverage
src/main.ts, src/main.test.ts
buildMarkdown uses the grouped table for passing results and the per-test table when failures or errors exist. Tests verify the passing output.
Estimated code review effort: 2 (Simple) ~10 minutes

The summary now uses a compact class-level table when no tests fail, but skipped tests may also enter that path and be presented as fully passed. The PR is otherwise mergeable with explicit owner awareness and a follow-up to distinguish genuinely all-passed runs from runs containing skipped tests.

Poem

A rabbit counts each passing test
By class and time, arranged with care
No check marks hop across the page
Failures keep their details there
The Markdown table stands clear

Assert the aggregated rows, not only the table header.

These assertions do not verify that groupByClass emits the expected class names, test counts, or summed durations. Add assertions for the expected rows from passing.xml so an empty or incorrect summary fails the test.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use an all-passed check before grouping results.

failed === 0 is also true when all contains skipped cases. The grouped branch then removes the :fast_forward: status, while the headline says that all tests passed. Require skipped === 0 as well, or check that every case has status "passed".

Suggested fix
-	if (failed === 0) {
+	if (failed === 0 && skipped === 0) {
