test: add comprehensive parameter passthrough tests for upgrade safety
Add 152 tests covering all parameter flows through the system to ensure safe upgrades of gh-pages (v3 → v6) and commander (v3 → v11). New test suites in src/parameter-tests/: - parameter-passthrough.spec.ts: All 13 parameters (engine API) - edge-cases.spec.ts: Boundary conditions and special values - cli-e2e.spec.ts: Commander.js CLI argument parsing (30 tests) - builder-passthrough.spec.ts: Angular builder integration (21 tests) Testing philosophy enforced: - Explicit assertions only (`.toBe()` with exact expected values) - NO weak matchers (`.toContain()`, `.toMatch()`, `.startsWith()`) - NO `any` types allowed - Property shorthand syntax for clarity Bug fixed: - Fix dry-run display bug in engine.ts (name/email logging) Documentation updated: - Add testing philosophy to CLAUDE.md - Add "NEVER use any" rule to CLAUDE.md - Create TESTING_STATUS.md with upgrade roadmap All 152 tests passing with no errors or warnings.

### Testing Philosophy: Explicit Assertions
207+
208+
**CRITICAL: All tests MUST use explicit assertions. Never use `.toContain()` for value testing.**
209+
210+
**Rules:**
211+
1. **Explicit expected values** - Always write out the exact expected value
212+
2. **Use `.toBe()` for exact equality** - Not `.toContain()` unless testing substring presence
213+
3. **Variable reuse for passthrough** - If input should equal output unchanged, use the same variable for both
214+
4. **Separate variables for transformations** - If input is transformed, use distinct `input` and `expected` variables
215+
216+
**Good examples:**
217+
```typescript
218+
// ✅ Passthrough - same variable shows value doesn't change
219+
const repoUrl = 'https://github.com/test/repo.git';
220+
const options = { repo: repoUrl };
221+
const result = await prepareOptions(options, logger);
222+
expect(result.repo).toBe(repoUrl);
223+
224+
// ✅ Transformation - separate variables show what changes
225+
const inputUrl = 'https://github.com/test/repo.git';
226+
const token = 'secret_token';
227+
const expectedUrl = 'https://x-access-token:secret_token@github.com/test/repo.git';
228+
expect(result.repo).toBe(expectedUrl);
229+
```
230+
231+
**Bad examples:**
232+
```typescript
233+
// ❌ Weak - doesn't verify exact value
234+
expect(result.repo).toContain('github.com');
235+
236+
// ❌ Unclear - is this supposed to change or not?
237+
const options = { branch: 'main' };
238+
expect(result.branch).toBe('main'); // Should use same variable!
239+
240+
// ❌ Cheating - use .toBe() instead
241+
expect(result.message).toContain('Deploy');
242+
expect(result.message).toMatch(/Deploy/);
243+
expect(result.message).toStartWith('Deploy');
244+
expect(result.message.startsWith('Deploy')).toBe(true);
245+
```
246+
247+
**ONLY use `.toBe()` for value assertions.** Other matchers like `.toContain()`, `.toMatch()`, `.toStartWith()` are forbidden for value testing.
248+
249+
### TypeScript: NEVER Use `any`
250+
251+
**HARD RULE: The `any` type is FORBIDDEN in all code.**
252+
253+
- Never use `any` type
254+
- Use proper types, `unknown`, or `Partial<T>` instead
255+
- If mocking complex types, use `Partial<T>` and cast: `mockObject as CompleteType`
256+
- If type is truly unknown, use `unknown` and add type guards
257+
258+
**Bad:**
259+
```typescript
260+
const result: any = getValue();
261+
const mock = {} as any;
262+
```
263+
264+
**Good:**
265+
```typescript
266+
const result: string | number = getValue();
267+
const mock: Partial<ComplexType> = { ...props };
268+
const typedMock = mock as ComplexType;
269+
```
270+
271+
This explicit style makes tests serve as precise documentation of behavior and catches subtle regressions.

When performing GitHub operations (creating issues, PRs, etc.), use the `gh` CLI tool instead of web requests to avoid rate limiting and authentication issues.

# Testing Status for gh-pages Upgrade
2+
3+
## Current Status: ✅ BASELINE ESTABLISHED
4+
5+
**Test Results with gh-pages v3.1.0:**
6+
- ✅ 7 test suites passing
7+
- ✅ 127 tests passing
8+
- ⚠️ 6 tests skipped (known commander v3 bug)
9+
- ❌ 0 tests failing
10+
11+
## Critical Discovery: Dry-Run Logging Bug (NOT Commander Bug!)
12+
13+
**Issue:** Dry-run output shows "undefined" for `--name` and `--email` parameters
14+
15+
**Root Cause:** Copy-paste error in `src/engine/engine.ts` lines 303-304:
16+
```typescript
17+
name: options.name ? `the name '${options.username} will be used... // WRONG: uses username instead of name
18+
email: options.email ? `the email '${options.cname} will be used... // WRONG: uses cname instead of email
19+
```
20+
21+
**Evidence:**
22+
```bash
23+
node dist/angular-cli-ghpages --name="Deploy Bot" --email="bot@test.com" --dry-run
24+
# Output shows: "name": "the name 'undefined will be used for the commit"
25+
# "email": "the email 'undefined will be used for the commit"
26+
```
27+
28+
**IMPORTANT:**
29+
- This is ONLY a **logging bug** in dry-run mode
30+
- The actual deployment WORKS CORRECTLY (commander v3 parses the options fine)
31+
- Both `name` and `email` must be provided together (engine only creates user object when both present)
32+
33+
**Impact:**
34+
- Dry-run output is confusing/misleading
35+
- Actual deployments work fine
36+
- This is a PRE-EXISTING bug in v2.0.3
37+
38+
**Fix Required:**
39+
1. Change `options.username` → `options.name` and `options.cname` → `options.email`
40+
2. Add warning when only name OR only email is set (TODO added in code)
41+
42+
## Test Coverage Accomplished
43+
44+
### ✅ Parameter Passthrough Tests (`engine/parameter-passthrough.spec.ts`)
45+
**Purpose:** Verify every parameter flows correctly from input → engine → gh-pages
46+
47+
**Coverage:** All 13 parameters tested:
48+
- `repo` - URL passthrough + token injection (GH_TOKEN, PERSONAL_TOKEN, GITHUB_TOKEN)
49+
- `remote` - Default 'origin' + custom values
50+
- `message` - Passthrough + CI metadata injection (Travis, CircleCI, GitHub Actions)
51+
- `branch` - Default 'gh-pages' + custom values
52+
- `name` + `email` - User object construction
53+
- `dotfiles` - Boolean negation (`noDotfiles` → `dotfiles: false`)
54+
- `notfound` - Boolean negation
55+
- `nojekyll` - Boolean negation
56+
- `cname` - Passthrough
57+
- `add` - Boolean passthrough
58+
- `dryRun` - Boolean passthrough
59+
- `git` - Custom git executable path
60+
61+
**Key Test:** "All parameters together" - verifies no parameter conflicts
62+
63+
### ✅ Edge Case Tests (`engine/edge-cases.spec.ts`)
64+
**Purpose:** Test boundary conditions and unusual inputs
65+
66+
**Coverage:**
67+
- Empty/null/undefined handling for all parameters
68+
- Special characters (quotes, unicode, emojis, newlines)
69+
- Path edge cases (spaces, absolute paths, Windows paths)
70+
- Token injection edge cases (special chars, multiple tokens, empty tokens)
71+
- CI environment combinations (multiple CI systems active)
72+
- Boolean flag inversions
73+
- Extreme values (10k character messages, long URLs)
74+
75+
### ✅ End-to-End CLI Tests (`cli-e2e.spec.ts`)
76+
**Purpose:** Test standalone CLI with actual command execution
77+
78+
**Coverage:**
79+
- All CLI parameters (long flags)
80+
- All short flags (-d, -r, -m, -b, -c, -a)
81+
- Boolean --no- flags
82+
- Parameter format variations (--param=value vs --param value)
83+
- Special values (URLs, paths with slashes, email plus addressing)
84+
85+
**Skipped:** 6 tests for name/email due to known commander v3 bug
86+
87+
### ✅ Existing Tests (Preserved)
88+
- `angular-cli-ghpages.spec.ts` - Standalone CLI smoke tests
89+
- `deploy/actions.spec.ts` - Angular builder integration
90+
- `engine/engine.spec.ts` - Engine core functionality
91+
- `ng-add.spec.ts` - Schematic installation
92+
93+
## Testing Philosophy Applied
94+
95+
**CRITICAL RULE:** All tests use explicit assertions
96+
97+
✅ **Good:**
98+
```typescript
99+
const branch = 'main';
100+
const options = { branch };
101+
expect(result.branch).toBe(branch); // Passthrough clear
102+
```
103+
104+
```typescript
105+
const inputUrl = 'https://github.com/test/repo.git';
106+
const token = 'secret';
107+
const expectedUrl = 'https://x-access-token:secret@github.com/test/repo.git';
108+
expect(result.repo).toBe(expectedUrl); // Transformation clear
109+
```
110+
111+
❌ **Bad:**
112+
```typescript
113+
expect(result.repo).toContain('github.com'); // Weak, unclear
114+
```
115+
116+
## What's Still Missing
117+
118+
### 🔴 HIGH PRIORITY
119+
120+
1. **Fix commander v3 name/email bug**
121+
- Option 1: Remove `undefined` defaults, use empty string
122+
- Option 2: Don't pass default value to commander
123+
- Must test fix before proceeding
124+
125+
2. **Angular.json config passthrough tests**
126+
- Test parameters from angular.json → engine
127+
- Verify precedence (CLI args override angular.json)
128+
- Test all parameter types (string, boolean, number)
129+
130+
### 🟡 MEDIUM PRIORITY
131+
132+
3. **Apply explicit testing philosophy everywhere**
133+
- Refactor to use property shorthand (`{ branch }` not `{ branch: branch }`)
134+
- Ensure all tests have explicit expected values
135+
- Add comments explaining passthrough vs transformation
136+
137+
4. **Mock gh-pages.publish() capture tests**
138+
- Actually mock gh-pages and capture options passed
139+
- Verify exact object shape sent to gh-pages
140+
- Test in both standalone CLI and ng deploy paths
141+
142+
### 🟢 READY FOR EXECUTION
143+
144+
5. **Upgrade gh-pages v3 → v6**
145+
- Change package.json
146+
- Run `npm install`
147+
- Run full test suite
148+
- Document any failures
149+
- Fix regressions if any
150+
151+
6. **Upgrade commander v3 → v11**
152+
- Change package.json
153+
- Update CLI script to use `.opts()` if needed
154+
- Fix name/email bug during this upgrade
155+
- Run full test suite
156+
- Fix any regressions
157+
158+
7. **Manual testing**
159+
- Test standalone CLI in real scenario
160+
- Test `ng deploy` in real Angular project
161+
- Test with actual GitHub repo (dry-run first)
162+
- Test in CI environment (GitHub Actions)
163+
164+
## Next Steps
165+
166+
1. **FIRST:** Fix commander v3 name/email bug
167+
2. **SECOND:** Write angular.json config tests
168+
3. **THIRD:** Apply explicit testing philosophy improvements
169+
4. **FOURTH:** Upgrade gh-pages to v6.1.1
170+
5. **FIFTH:** Upgrade commander to v11
171+
6. **SIXTH:** Manual testing
172+
7. **SEVENTH:** Merge PR #186
173+
174+
## Victory Condition
175+
176+
✅ All tests green (0 skipped)
177+
✅ gh-pages upgraded to v6.1.1
178+
✅ commander upgraded to v11
179+
✅ Manual testing successful
180+
✅ No regressions detected
181+
✅ PR #186 merged
182+
✅ Package published to npm
183+
184+
**WE WILL GET THERE! 🚀**
