### [Planner] Research Notes - RECIPE-0006 Iteration 1 (2026-02-17)
|
||||
|
||||
**Task:** Transform E2E test to unit test with mocked fixtures and fix extraction logic iteratively
|
||||
|
||||
#### Problem Analysis
|
||||
**Research Date:** 2026-02-17T10:00:00.000Z
|
||||
**Source:** review_report.yaml, extraction.ts analysis, test fixtures
|
||||
|
||||
**Iteration 0 Failure:**
|
||||
- E2E test created but never executed during development
|
||||
- User manually ran test and it FAILED
|
||||
- Current output: `"16K likes, 325 comments - chef.antonio.la.cava on October 17, 2025: "La cacio e pepe..."`
|
||||
- Expected output: Full recipe starting with `"La cacio e pepe infallibile di Luciano Monosilio 🍝"`
|
||||
|
||||
**Root Cause Analysis:**
|
||||
1. **DOM selectors failing**: Lines 331-341 of extraction.ts try selectors but none match Instagram's current structure
|
||||
2. **Fallback to og:description**: Line 348-357 extracts from `<meta property="og:description">` which contains metadata prefix
|
||||
3. **Regex cleanup insufficient**: Line 356 tries to clean metadata with regex `^\d+K?\s+likes,\s+\d+\s+comments\s+-\s+[\w.]+\s+on\s+[^:]+:\s+` but it's not removing the text properly
|
||||
|
||||
**Current extractFromDOM() Flow:**
|
||||
```
|
||||
1. Try selectors: article h1, article span[dir="auto"], article div[role="button"] + span, article span:not([aria-label])
|
||||
→ All fail (return null or < 100 chars)
|
||||
2. Fallback to og:description meta tag
|
||||
→ Returns: "16K likes, 325 comments - username on date: caption..."
|
||||
3. Apply metadata cleanup regex
|
||||
→ Regex doesn't match properly (or matches but leaves quotes)
|
||||
4. Pass to cleanText()
|
||||
→ cleanText() removes hashtags but metadata prefix remains
|
||||
```

#### Vitest Unit Testing for Playwright Mocking
|
||||
**Research Date:** 2026-02-17T10:00:00.000Z
|
||||
**Source:** TESTING.md, existing tests (queue-processor.spec.ts, scheduler.spec.ts)
|
||||
|
||||
**Mocking Strategy:**
|
||||
From TESTING.md and existing test patterns, Vitest provides module-level mocking:
|
||||
|
||||
```typescript
|
||||
// Mock entire module BEFORE imports
|
||||
vi.mock('$lib/server/extraction', () => ({
|
||||
extractTextAndThumbnail: vi.fn().mockResolvedValue({
|
||||
bodyText: 'Mocked text',
|
||||
thumbnail: 'https://example.com/thumb.jpg'
|
||||
})
|
||||
}));
|
||||
```
|
||||
|
||||
**For Unit Testing extractFromDOM():**
|
||||
- Cannot mock the entire `extraction.ts` module (we're testing functions inside it)
|
||||
- Need to test internal functions directly (extractFromDOM, cleanText are not exported)
|
||||
- Options:
|
||||
1. **Export functions for testing** (add `export` to extractFromDOM and cleanText)
|
||||
2. **Mock Playwright Page.evaluate()** (mock the browser automation layer)
|
||||
3. **Integration test with mocked browser context**
|
||||
|
||||
**Chosen Approach: Export Internal Functions**
|
||||
- Cleanest separation of concerns
|
||||
- Allows direct unit testing without browser overhead
|
||||
- Follows existing pattern (extractTextAndThumbnail is already exported)
|
||||
- Test Runtime: < 10ms (vs 30s for E2E test)
|
||||
|
||||
**Test Structure:**
|
||||
```typescript
|
||||
// Unit test with fixtures
|
||||
import { extractFromDOM, cleanText } from '$lib/server/extraction';
|
||||
|
||||
describe('Instagram Caption Extraction Unit Tests', () => {
|
||||
it('should clean metadata prefix from og:description', async () => {
|
||||
const input = '16K likes, 325 comments - chef.antonio.la.cava on October 17, 2025: "La cacio e pepe...';
|
||||
const expected = 'La cacio e pepe infallibile di Luciano Monosilio...';
|
||||
|
||||
// Create mock page that returns problematic og:description
|
||||
const mockPage = {
|
||||
evaluate: vi.fn().mockResolvedValue(input)
|
||||
};
|
||||
|
||||
const result = await extractFromDOM(mockPage as any);
|
||||
expect(result.bodyText).toBe(expected);
|
||||
});
|
||||
});
|
||||
```

#### Metadata Prefix Regex Analysis
|
||||
**Research Date:** 2026-02-17T10:00:00.000Z
|
||||
**Source:** extraction.ts line 356, test fixtures
|
||||
|
||||
**Current Regex (Line 356):**
|
||||
```typescript
|
||||
const cleanedContent = content.replace(/^\d+K?\s+likes,\s+\d+\s+comments\s+-\s+[\w.]+\s+on\s+[^:]+:\s+/, '');
|
||||
```
|
||||
|
||||
**Test Against Actual Input:**
|
||||
```
|
||||
Input: '16K likes, 325 comments - chef.antonio.la.cava on October 17, 2025: "La cacio e pepe...'
|
||||
Pattern: '^\d+K?\s+likes,\s+\d+\s+comments\s+-\s+[\w.]+\s+on\s+[^:]+:\s+'
|
||||
^----- Should match "16K likes, 325 comments - chef.antonio.la.cava on October 17, 2025: "
|
||||
```
|
||||
|
||||
**Issue:** Pattern matches but leaves opening quote `"` after the colon.
|
||||
|
||||
**Problems Identified:**
|
||||
1. Pattern doesn't account for quotes after colon
|
||||
2. Date pattern `[^:]+` is too greedy (matches "October 17, 2025")
|
||||
3. Pattern assumes single space after colon, but actual format may have `": "` (colon-space-quote)
|
||||
|
||||
**Improved Regex:**
|
||||
```typescript
|
||||
// Match: "X likes, Y comments - username on date: " (with optional quote)
|
||||
/^\d+K?\s+likes,\s+\d+\s+comments\s+-\s+[\w.]+\s+on\s+[^:]+:\s*["']?/
|
||||
```
|
||||
|
||||
**Breakdown:**
|
||||
- `^\d+K?` - Matches "16K" or "16" (K is optional)
|
||||
- `\s+likes,\s+\d+\s+comments` - Matches " likes, 325 comments"
|
||||
- `\s+-\s+[\w.]+` - Matches " - chef.antonio.la.cava" (alphanumeric + dots)
|
||||
- `\s+on\s+[^:]+:` - Matches " on October 17, 2025:" (anything before colon)
|
||||
- `\s*` - Optional whitespace after colon
|
||||
- `["']?` - Optional quote character (single or double)
|
||||
|
||||
**This should properly strip:**
|
||||
- `"16K likes, 325 comments - chef.antonio.la.cava on October 17, 2025: "` → (empty)
|
||||

|
||||
#### Files to Modify - RECIPE-0006 Iteration 1
|
||||
|
||||
**Primary Changes:**
|
||||
1. **src/lib/server/extraction.ts**
|
||||
- Export `extractFromDOM` for unit testing
|
||||
- Export `cleanText` for unit testing
|
||||
- Fix metadata prefix regex in extractFromDOM() (line 356)
|
||||
|
||||
2. **src/tests/instagram-caption-extraction.unit.spec.ts** (NEW)
|
||||
- Replace E2E test with unit test
|
||||
- Mock page.evaluate() to return test fixtures
|
||||
- Test both problematic and expected outputs
|
||||
- Runtime < 100ms
|
||||
|
||||
3. **src/tests/instagram-caption-extraction.e2e.spec.ts** (MODIFY)
|
||||
- Mark as `.skip` or remove (replaced by unit test)
|
||||
- Keep file for future real-world validation (optional)
|
||||
|
||||
**Dependencies:**
|
||||
- Vitest mocking (vi.fn(), mockResolvedValue)
|
||||
- Test fixtures from context_compact.yaml
|
||||
- No external libraries needed
|
||||
|
||||
**Parallelization:**
|
||||
- All changes are independent
|
||||
- Unit test can be written in parallel with extraction.ts fix
|
||||
- Test validates fix iteratively

* E2E Test for Instagram Caption Extraction
|

*
|

* JIRA: RECIPE-0006
|

*
|
||||
* CURRENT STATUS: Instagram actively prevents web scraping.
|
||||
* - All extraction methods (JSON, DOM, Internal State) return only truncated text (≤130 chars)
|
||||
* - Full captions are loaded dynamically via GraphQL after user interaction
|
||||
* - "More" button expansion requires complex interaction simulation
|
||||
*
|
||||
* This test validates that:
|
||||
* 1. Multiple extraction strategies are attempted
|
||||
* 2. The test fails if ALL strategies produce truncated output
|
||||
* 3. Anti-scraping detection is working
|
||||
*
|
||||
* To get full captions, consider:
|
||||
* - Official Instagram Graph API (requires authentication)
|
||||
* - Manual user flow simulation with authenticated browser
|

* - Alternative data sources
