# Testing & Metrics Guide
2+
3+
The UI5 Guidelines plugin uses a unified test framework for structure validation, triggering tests, and performance checks.
4+
5+
## Quick Start
6+
7+
```bash
8+
# Run all tests
9+
npm test
10+
11+
# Specific test suites
12+
npm run test:structure # Plugin structure validation
13+
npm run test:triggering # Skill triggering accuracy
14+
npm run test:performance # Context budget checks
15+
```
16+
17+
## Test Suites
18+
19+
### 1. Structure Tests
20+
21+
Validates plugin integrity:
22+
-`plugin.json` is valid JSON
23+
- ✅ All referenced skills exist
24+
- ✅ SKILL.md files have proper YAML frontmatter
25+
- ✅ No broken internal links
26+
27+
### 2. Triggering Tests
28+
29+
Validates skill selection accuracy:
30+
- Test cases defined in `test/fixtures/trigger-cases.json`
31+
- Checks skills trigger on appropriate prompts
32+
- Reports accuracy (target: >90%)
33+
34+
**Add test cases when**:
35+
- A skill doesn't trigger when expected
36+
- New triggering keywords are added
37+
38+
### 3. Performance Tests
39+
40+
Validates context budget:
41+
- Main skill files under 900 lines (warning >700)
42+
- Total context reasonable (<3000 lines)
43+
- Large skills use reference files
44+
45+
## Metrics
46+
47+
### View Analytics
48+
49+
```bash
50+
# Load sample data (for testing)
51+
npm run seed-metrics
52+
53+
# View dashboard
54+
npm run metrics # Last 7 days
55+
npm run metrics:week # Last 7 days
56+
npm run metrics:month # Last 30 days
57+
npm run metrics:optimize # With optimization tips
58+
```
59+
60+
### Tracked Data
61+
62+
The plugin tracks (stored in `.metrics/usage.jsonl`, gitignored):
63+
- Skill invocations
64+
- Context size (lines & tokens)
65+
- Session IDs
66+
- Timestamps
67+
68+
### Metrics Output
69+
70+
```
71+
📊 UI5 Guidelines Plugin - Usage Analytics (Last 7 days)
72+
73+
Overall Stats:
74+
Total sessions: 45
75+
Total skill invocations: 128
76+
Average context: 2,156 lines (~8,624 tokens)
77+
78+
Per-Skill Breakdown:
79+
ui5-best-practices: 48 invocations (37.5%)
80+
ui5-typescript-expert: 42 invocations (32.8%)
81+
ui5-integration-cards: 38 invocations (29.7%)
82+
```
83+
84+
## Test Configuration
85+
86+
### Matching Algorithm
87+
88+
Configuration in `test/config/matching-config.json`:
89+
90+
```json
91+
{
92+
"weights": {
93+
"keywordMatch": 3,
94+
"exactPhrase": 10,
95+
"wordOverlap": 0.2
96+
},
97+
"ui5Terms": ["ui5", "sapui5", "openui5", ...],
98+
"antiPatterns": ["react hook", "python", "django", ...],
99+
"exactPhrases": ["component metadata", "minui5version"]
100+
}
101+
```
102+
103+
**Tune weights** to adjust skill selection accuracy.
104+
105+
## Adding Test Cases
106+
107+
Edit `test/fixtures/trigger-cases.json`:
108+
109+
```json
110+
{
111+
"tests": [
112+
{
113+
"prompt": "How do I set up async module loading?",
114+
"expected_skill": "ui5-best-practices",
115+
"should_trigger": true
116+
},
117+
{
118+
"prompt": "React hooks tutorial",
119+
"expected_skill": null,
120+
"should_trigger": false,
121+
"reason": "React, not UI5"
122+
}
123+
]
124+
}
125+
```
126+
127+
## Current Test Results
128+
129+
**Structure**: 16/16 passing (100%)
130+
**Triggering**: 45/46 passing (97.8%)
131+
**Performance**: 6/7 passing
132+
133+
## Troubleshooting
134+
135+
### Low Triggering Accuracy
136+
137+
1. Add missing keywords to skill YAML frontmatter
138+
2. Update `test/config/matching-config.json` weights
139+
3. Add specific test cases
140+
141+
### Slow Tests
142+
143+
1. Check test framework isn't loading unnecessary files
144+
2. Reduce number of test cases if needed
145+
3. Use `npm run test:triggering` for quick checks
146+
147+
## Test Framework Details
148+
149+
**Technology**: TypeScript ESM with strict mode
150+
151+
**Structure**:
152+
```
153+
test/
154+
├── index.ts # Test runner
155+
├── types.ts # Type definitions
156+
├── lib/
157+

├── suites/

├── trigger-cases.json # Test cases
167+
└── sample-metrics.jsonl # Sample analytics data
168+
```
169+
170+
## Best Practices
171+
172+
**DO**:
173+
- Run tests before committing
174+
- Add test cases for new keywords
175+
- Keep test execution fast (<5s)
176+
- Use sample metrics for analytics testing
177+
178+
**DON'T**:
179+
- Modify test framework without understanding impact
180+
- Commit `.metrics/` directory (gitignored)
181+
- Skip tests when changing skill descriptions
182+
- Hardcode test expectations in code (use JSON)
