Why This Tool Cannot Guarantee 100% Coverage
Rihario cannot guarantee 100% test coverage because AI exploration is probabilistic, not exhaustive. The AI explores what it finds, takes different paths each time, and focuses on obvious issues. It's optimized for finding problems quickly, not for comprehensive coverage. This is by design - we focus on confidence, not coverage.
Why Coverage Guarantees Are Impossible
1. Probabilistic Exploration
AI exploration is probabilistic:
- Different paths each time - Same exploration may take different routes
- Not deterministic - Cannot predict exactly what will be explored
- Explores what it finds - Follows paths it discovers, not exhaustive checklist
2. Focus on Obvious Issues
AI focuses on finding problems:
- Obvious bugs - Things that clearly look broken
- High-impact issues - Problems that affect users
- Common flows - Typical user paths
- Not edge cases - Doesn't test every possible scenario
3. Time and Resource Limits
Exploration has practical limits:
- Time limits - Cannot explore indefinitely
- Resource constraints - Limited by compute resources
- Efficiency focus - Optimized for speed, not completeness
What "Coverage" Means Here
What We Don't Mean
- Code coverage - Not measuring lines of code tested
- Feature coverage - Not testing every feature
- Scenario coverage - Not testing every possible scenario
- Edge case coverage - Not testing unusual situations
What We Do Mean
- Exploration of found paths - Explores routes it discovers
- Obvious issue detection - Finds problems that are clearly broken
- Common flow testing - Tests typical user journeys
- Confidence building - Helps you feel confident before shipping
What Gets Tested
AI exploration typically covers:
- Main user flows - Common paths through your app
- Visible elements - Things that appear on pages
- Obvious issues - Problems that are clearly broken
- Standard interactions - Clicks, forms, navigation
What Might Be Missed
AI exploration might miss:
- Edge cases - Unusual scenarios or inputs
- Hidden features - Features not easily discoverable
- Complex business logic - Subtle logic errors
- Performance issues - Slow but functional features
- Security vulnerabilities - Advanced security issues
- Accessibility edge cases - Complex accessibility problems
Why This Is Okay
Focus on Confidence
Rihario focuses on confidence, not coverage:
- "Nothing obviously broken" - More important than complete coverage
- "Safe to ship" - Goal is shipping confidence, not perfection
- "Quick checks" - Fast exploration over exhaustive testing
Practical Trade-offs
For solo developers and indie builders:
- Time is valuable - Fast checks better than slow comprehensive tests
- Obvious bugs matter most - Catching embarrassing bugs is priority
- Coverage isn't everything - Perfect coverage doesn't guarantee no bugs
How to Use Rihario Effectively
Set Realistic Expectations
- Don't expect 100% coverage - That's not the goal
- Expect obvious issues found - Will catch clear problems
- Use for confidence - Helps you feel ready to ship
Supplement with Manual Testing
- Test critical flows manually - Verify important paths yourself
- Test edge cases - Cover unusual scenarios manually
- Use Rihario for quick checks - AI finds obvious issues, you find subtle ones
Focus on Value
- Find obvious problems fast - Catch embarrassing bugs quickly
- Build confidence - Know nothing is obviously broken
- Ship with confidence - Not perfection, but confidence
Comparison to Traditional Testing
| Aspect | Traditional Testing | Rihario |
|---|---|---|
| Coverage Goal | High coverage (80-90%+) | Confidence, not coverage |
| Approach | Exhaustive, deterministic | Probabilistic, focused |
| Speed | Slow (comprehensive) | Fast (quick checks) |
| Best For | QA teams, compliance | Solo devs, quick checks |
Summary
Rihario cannot guarantee 100% coverage because:
- AI exploration is probabilistic, not exhaustive
- Focuses on obvious issues, not edge cases
- Has practical time and resource limits
- Optimized for confidence, not coverage
This is by design. Use Rihario for quick confidence checks, not comprehensive coverage. Supplement with manual testing for critical flows and edge cases.
