fix(debug): report silent best-effort failures under --debug by bhushan4work · Pull Request #731 · TestSprite/testsprite-cli

bhushan4work · 2026-11-11T15:50:20Z

What does this PR do?

Reports best-effort failures from nine previously silent catch sites on stderr when --debug is set, without changing stdout, return values, or behavior when --debug is absent.

Changed sites:

src/commands/test.ts ×5: run-card backend type lookup, JUnit test-name lookup, rerun auto-heal type lookup, flaky credit-advisory type lookup, plan baseline read.
src/lib/bundle.ts ×1: video extension URL parse.
src/lib/dry-run/fetch.ts ×1: dry-run request body parse.
src/lib/facade.ts ×2: portal override URL parse and API URL parse.

Tests added for all nine sites, asserting byte-identical output without --debug and diagnostics only on stderr with it.

The full npm test suite was not run in this session.

Summary by CodeRabbit

Improvements
- Debug mode now provides diagnostic messages for certain failed lookups and parsing errors, including invalid URLs, request bodies, and video links.
- These messages are written to standard error. Normal command output and existing fallback behavior remain unchanged, and the diagnostics are not emitted when debug mode is off.

Walkthrough

Selected best-effort lookup and parsing failures now produce stderr diagnostics when debug mode is enabled. Command paths pass debug and stderr settings to supporting functions. Existing fallback results and normal-mode output are covered by tests.

Changes

Debug diagnostics

Layer / File(s)	Summary
Library parsing diagnostics `src/lib/facade.ts`, `src/lib/facade.test.ts`, `src/lib/dry-run/fetch.ts`, `src/lib/dry-run/fetch.test.ts`, `src/lib/client-factory.ts`, `src/lib/bundle.ts`, `src/lib/bundle.test.ts`	Portal URL, dry-run request-body, and video URL parsing failures can report their error through stderr when debug mode is enabled. Existing results and fallbacks remain unchanged.
Command lookup diagnostics `src/commands/test.ts`, `src/commands/test.debug.spec.ts`, `src/commands/test.flaky.spec.ts`, `src/commands/test.plan.spec.ts`, `src/commands/test.rerun.spec.ts`	Selected failed lookups emit diagnostics in debug mode. Command paths pass debug and stderr settings to portal resolution and bundle writing. Tests compare debug and normal output and check fallback results.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Debug-only diagnostics could echo credential-shaped text from error messages to stderr. The risk is bounded to users who enable --debug, and the fix is small. Normal output is unchanged.

Full details: Out of Scope Changes check

Explanation

The source changes add diagnostics and option plumbing for the silent catch sites named by issue #186. The new tests verify diagnostics and unchanged command output. No unrelated behavior or feature change is established.

Full details: Linked Issues check

Explanation

Issue #186 requires debug diagnostics gated by --debug or --verbose. The nine new handlers in test.ts, bundle.ts, dry-run/fetch.ts, and facade.ts check only debug. The added tests also cover only debug mode. Existing skill-nudge.ts code already contains debug-gated diagnostics, so this assessment does not require that code to be reimplemented. The PR evidence does not establish equivalent verbose behavior for the new sites.

Resolution

Support opts.verbose as required by issue #186, or document and obtain agreement that this issue scope is debug-only. Add tests for verbose diagnostics and unchanged output when neither flag is set.

Full details: Docstring Coverage

Explanation

Docstring coverage is 42.86% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 7 functions across 11 files. (1 skipped: 1 too large.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Redact lookup error messages before debug output.

If a lookup error contains a bearer token, this diagnostic can write it to stderr unchanged. Apply the existing string redaction here and to the new JUnit, rerun, replay, and baseline lookup diagnostics.

Redact the run-card diagnostic

+import { redactDeep } from '../lib/redact.js'; import { globalShutdown, type ShutdownHandle } from '../lib/interrupt.js';

const reason = err instanceof Error ? err.message : String(err); - stderrFn(`[debug] run card backend type lookup failed: ${reason}`); + stderrFn(`[debug] run card backend type lookup failed: ${redactDeep(reason)}`);

Do not print request-body excerpts through parser errors.

On supported Node 22.13.0, JSON.parse errors can include the input text around the invalid token. This diagnostic therefore exposes body content when parsing fails under debug. The runtime source explicitly inserts the original input or a substring into these messages. (raw.githubusercontent.com)

Emit a fixed parse-failure reason, or sanitize the message before writing it. Add a malformed-body case containing a synthetic password or token and assert that stderr excludes the value.

As per path instructions, “credential-shaped fields are redacted in error details and debug traces.” Based on learnings, serialized diagnostic errors require secret-redaction checks.

Keep diagnostic sink failures from changing the result.

When the supplied stderr callback throws, these catch handlers throw instead of returning undefined. On the create paths, this happens after the create POST succeeds and before the receipt prints (src/commands/test.ts, Lines 1807–1814).

Use a non-throwing diagnostic writer. Apply the same protection to the new diagnostic writes in bundle.ts, dry-run/fetch.ts, and commands/test.ts. Cover a throwing callback in the fallback tests.

As per path instructions, “Keep optional diagnostics from changing command behavior or exit status.”
