fix(ci): test summary/JUnit dropped OpenTofu runs and late diagnostics by osterman · Pull Request #3082 · cloudposse/atmos

Erik Osterman (Cloud Posse) (osterman) · 2026-09-08T12:15:06Z

Summary

atmos terraform test --ci discarded every run and file event from tofu test -json: OpenTofu emits one test_run/test_file event per subject carrying only status, with no progress field, and the parser only accepted events with progress: "complete". The test_summary event has the same shape in both tools, so badge counts stayed right while the results table came out empty and <component>.junit.xml reported tests="0" on a passing run.
Both Terraform and OpenTofu emit an assertion-failure diagnostic after the run's final event; the parser only attached diagnostics that arrived before it, so failing runs lost their message and file:line (and with them the ::error annotation and the summary's Details column) under Terraform too.
Fix: testEventComplete accepts a bare terminal status as final; attachLateDiagnostics reconciles diagnostics that arrive after their run. The stop-gap backfillMissingTestJSONRuns guard stays as a last resort but now warns loudly if it ever fires.
Also closes out a related, already-fixed emulator-endpoint report: confirmed via git merge-base --is-ancestor and a fresh Docker repro that Shared per-stack networking for containers, emulators & run steps #2942/fix(emulator): join Atmos's container to the shared network when reuse fails #2960 are intact and shipped in v1.228.0; re-verification note appended to the existing fix doc.

Why

The report came from a repository whose toolchain pins tofu. This repo's own examples/terraform-tests fixture is Terraform-only (it uses variable blocks that OpenTofu rejects), so eleven local repro runs never hit it; diffing raw -json streams from both tools on a minimal module exposed the missing progress field and the diagnostic ordering.

Verification

New regression tests use verbatim OpenTofu 1.12.5 streams; they failed before the parser change with every run reported as run detail unavailable (pass) and no file/line.
End-to-end under OpenTofu (components.terraform.command: tofu, one passing + one failing run, GITHUB_ACTIONS=true … --ci): JUnit tests="2" failures="1" with real names and line="12" on the failure; summary lists both runs with tests/min.tftest.hcl:12 in Details; ::error file=…,line=12 annotation emitted.
Terraform path unchanged: examples/terraform-tests still yields tests="4" with all real run names.

Summary by CodeRabbit

Bug Fixes
- Fixed CI test reporting for OpenTofu, ensuring test runs and files appear in summaries and JUnit results.
- Preserved assertion diagnostics even when they arrive after a test completes.
- Added safeguards for missing test-run records, including limits on synthesized entries to prevent incomplete or unbounded output.
- Clearly indicate when test results are incomplete due to truncation.
Documentation
- Added re-verification details for emulator networking and endpoint connectivity in the published release image.

…s tests="0" on a passing run `terraform test -json`'s authoritative test_summary event can report a passing run while one or more per-run test_run "complete" events never make it into data.Runs. Since both the JUnit report and the CI step-summary results table only ever iterate data.Runs, that gap silently produced tests="0" and an empty results table despite the run genuinely passing. backfillMissingTestJSONRuns reconciles data.Runs against the summary counts so the numbers stay truthful, mirroring the synthesizeFallbackRun convention already used on the text-output parsing path. Also appends a re-verification note to the 2026-08-19 emulator-endpoint fix doc: confirmed via git merge-base --is-ancestor and a fresh Docker repro that the prior job-container networking fix (#2942, #2960) is unaffected and already shipped in v1.228.0 -- no code change needed there.

… summary/JUnit The `test -json` parser only accepted a test_run/test_file event as final when it carried progress: "complete". OpenTofu never emits a progress field -- it emits one event per run/file with only the final status -- so under tofu every run and file was discarded. test_summary has the same shape in both tools, so badge counts stayed right while the results table was empty and the JUnit report said tests="0" on a passing run. Both tools also emit an assertion-failure diagnostic after the run's final event, but diagnostics were only attached when they arrived before it, so failing runs lost their message and file:line (and the ::error annotation) under Terraform as well. testEventComplete treats a bare terminal status as final; attachLateDiagnostics reconciles diagnostics that arrive after their run. The stop-gap backfill guard stays as a last resort and now warns when it fires. Regression tests use verbatim OpenTofu 1.12.5 streams; the fix doc is rewritten around the real root cause and renamed accordingly. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

📝 Walkthrough

Walkthrough

The parser now supports OpenTofu test JSON events without progress, preserves diagnostics emitted after completion, bounds missing-run backfills, and reports incomplete output. The fix documentation records emulator endpoint re-verification.

Changes

Test JSON parsing

Layer / File(s)	Summary
Event completion and output state `pkg/ci/plugins/terraform/parser.go`, `pkg/ci/internal/plugin/types.go`	Completion checks accept status-only OpenTofu events. Parsed output records truncated backfills.
Finalization and bounded backfill `pkg/ci/plugins/terraform/parser.go`, `pkg/ci/plugins/terraform/handlers.go`	Finalization attaches late diagnostics and limits synthetic runs to 10,000 per status. Truncation marks results as errors and adds an incomplete-output status message.
Parser regression validation `pkg/ci/plugins/terraform/test_json_test.go`, `docs/fixes/2026-09-08-ci-test-json-opentofu-runs-dropped.md`, `docs/fixes/2026-09-08-ci-test-json-backfill-unbounded-synthetic-runs.md`	Tests cover OpenTofu parsing, diagnostic ordering, summary backfills, cap enforcement, JUnit output, and text output. Documentation records validation results.

Emulator endpoint validation

Layer / File(s)	Summary
Published image re-verification `docs/fixes/2026-08-19-emulator-endpoint-job-container-network-join.md`	The validation entry records ancestor checks and a successful HTTP 200 response from the published emulator endpoint without loopback or gateway fallback.
