Vlad MocanuandClaude Opus 4.6 7011b0f71a test: add mock tracking diagnostics for Forgejo CI debugging
DI fix passes locally in grunt-runner Docker but still fails on
actual Forgejo runner. Adding diagnostic tests to isolate whether
mock() tracking itself is broken, or something else in the runner
environment causes it.

# PRD #6: E2E Test All Untested Forgejo Trigger Scenarios
**Issue**: [#6](https://git.wxs.ro/actions/claude-code-action/issues/6)
**Priority**: High
**Created**: 2026-02-25
---
## Problem
The Forgejo platform support (PRD #1) was validated for the two most common scenarios (agent mode via `workflow_dispatch` and tag mode via `issue_comment`). However, 5 trigger scenarios remain untested in a live environment:
1. PR review comment triggers (`pull_request_review_comment`)
2. PR review triggers (`pull_request_review`)
3. Label triggers (`issues` with `labeled` action)
4. Assignee triggers (`issues` with `assigned` action)
5. Branch creation + code changes from tag mode (the initial test only asked a question, no code was generated)
These untested paths could have silent failures — the code may look correct but break on Forgejo's subtly different webhook payloads, API responses, or event structures.
## Solution
Systematically exercise each untested scenario on the live Forgejo instance (git.wxs.ro), document results, fix any issues discovered, and update the E2E status table in `docs/forgejo.md`.
## Milestones
- [x] **M1: Ensure workflow covers all trigger types**
- Review `.forgejo/workflows/claude.yml` to confirm all 5 trigger types are listed
- Add any missing triggers to the workflow file
- Ensure the workflow has the correct permissions for each trigger type
- **Validation**: Workflow YAML includes all required `on:` triggers
- [ ] **M1.5: Fix image-downloader test failures blocking CI**
- **Problem**: All 18 `downloadCommentImages` tests failed on Forgejo CI (Linux Bun 1.2.21 in `harbor.wxs.ro/wxs/grunt-runner:v1.9.0`) while passing locally on macOS. This blocks all PRs.
- **What we know**: On this Linux Docker image, `mock()` and `spyOn()` call tracking from `bun:test` is broken for this file. Even with DI (no module-level mocking at all), mock functions report "not called" despite being invoked. The ONLY passing test uses a negative assertion. This is NOT a `mock.module` issue — it affects plain `mock()` functions passed as parameters too.
- **History of failed attempts** (5 so far):
1. Upstream uses `spyOn(fs, "mkdir")` — works on GitHub CI (Bun 1.2.12/ubuntu) but fails on Forgejo Linux
2. `96ec04e` tried `_fsForTest` mutable export — abandoned
3. `cff360d` tried dependency injection for fs mocks — still failed on CI
4. `dab92ef` tried `mock.module("fs/promises")` — works on macOS, fails on Linux
5. `c6ca8a7` removed `mock.module` entirely, used DI with `fsDeps` param — **still fails on CI** (mock tracking broken at a deeper level)
- **Next step**: Set up local Docker reproduction using `grunt-runner:v1.9.0` to debug interactively
- **Validation**: Pending — need local Docker repro first
- [ ] **M2: Test PR review comment trigger**
- Create a test PR on the repo
- Post a review comment with `@claude` mention
- Verify: platform detection, context fetching (PR diff, review comment body), tracking comment, Claude response
- Document any issues and fix them
- **Validation**: Claude responds correctly to `@claude` in a PR review comment
- [ ] **M3: Test PR review trigger**
- Create a test PR on the repo
- Submit a review with `@claude` mention in the review body
- Verify: platform detection, context fetching, tracking comment, Claude response
- Document any issues and fix them
- **Validation**: Claude responds correctly to `@claude` in a PR review
- [ ] **M4: Test label trigger**
- Create a label (e.g., `claude`) that triggers the action when applied to an issue
- Apply the label to a test issue
- Verify: trigger detection, context fetching (issue body/title), Claude response
- Document any issues and fix them
- **Validation**: Claude responds when the configured label is applied to an issue
- [ ] **M5: Test assignee trigger**
- Assign a user to an issue to trigger the action
- Verify: trigger detection, context fetching, Claude response
- Document any issues and fix them
- **Validation**: Claude responds when assigned to an issue
- [ ] **M6: Test tag mode with code changes (branch creation)**
- Create an issue requesting a code change (e.g., "add a comment to file X")
- Trigger Claude via `@claude` mention
- Verify: Claude creates a branch, pushes commits, links the branch in tracking comment
- Verify the Forgejo-specific PR compare URL format is correct
- **Validation**: Claude successfully creates a branch with code changes on Forgejo
- [ ] **M7: Update documentation with E2E results**
- Update `docs/forgejo.md` E2E status table with results for all 5 scenarios
- Move tested items from "Not Yet E2E Tested" to the validated table
- Document any Forgejo-specific quirks or limitations discovered
- Add troubleshooting entries for any issues encountered
- **Validation**: `docs/forgejo.md` accurately reflects the current E2E validation status
## Dependencies
- PRD #5 (Dedicated Forgejo User) is recommended but not strictly required — tests can run with the current token setup
- A test repository on git.wxs.ro with the action workflow configured
## Risks
| Risk | Mitigation |
| -------------------------------------------------------- | ----------------------------------------------------------- |
| Forgejo webhook payloads differ from expected | Log raw payloads, compare with GitHub format, adapt parsing |
| Trigger type not supported by Forgejo Actions | Document as known limitation, skip gracefully |
| Action creates unwanted branches/comments during testing | Use a dedicated test repo or clean up after each test |
| Bun mock.module breaks mock tracking on Linux | Use dependency injection for fs mocks, never mock.module |
## Success Criteria
- All 5 previously untested scenarios have been exercised on a live Forgejo instance
- Any bugs discovered are fixed and tested
- `docs/forgejo.md` E2E status table is fully up-to-date
- "Not Yet E2E Tested" section is empty (all items moved to validated or documented as unsupported)
