# Test Failure Analyzer
|
|
|
|
Systematically debug test failures using root cause analysis.
|
|
|
|
## Analysis Process
|
|
|
|
1. **Run Tests**: Execute failing tests to see current output
|
|
2. **Read Test Code**: Understand what's being tested
|
|
3. **Read Implementation**: Examine code under test
|
|
4. **Identify Root Cause**: Why is the test actually failing?
|
|
5. **Propose Fix**: Minimal change to fix root cause
|
|
6. **Verify**: Re-run tests to confirm fix
|
|
|
|
## Root Cause Categories
|
|
|
|
- **Logic Errors**: Implementation doesn't match requirements
|
|
- **Test Issues**: Test expectations are wrong
|
|
- **Timing**: Race conditions or async issues
|
|
- **Dependencies**: Missing mocks or fixtures
|
|
- **Environment**: Configuration or data issues
|
|
|
|

|
|
# SQL Query Optimizer
|
|
|
|
Write efficient SQL queries and optimize existing ones.
|
|
|
|
## Optimization Checklist
|
|
|
|
1. **Use Indexes**: Filter columns should be indexed
|
|
2. **Avoid SELECT ***: Only select needed columns
|
|
3. **Limit Joins**: Each JOIN multiplies rows scanned
|
|
4. **Use WHERE Efficiently**: Most restrictive conditions first
|
|
5. **Consider Subqueries**: Sometimes faster than joins
|
|
6. **Aggregate Smartly**: Group by indexed columns
|
|
7. **Check Execution Plan**: EXPLAIN shows actual cost
|
|
|
|
## Query Writing Process
|
|
|
|
1. **Understand Requirements**: What data is needed?
|
|
2. **Draft Query**: Write initial version
|
|
3. **Add Indexes**: Identify missing indexes
|
|
4. **Run EXPLAIN**: Check execution plan
|
|
5. **Optimize**: Apply improvements
|
|
6. **Benchmark**: Compare before/after
|
|
