# feat(hooks): Reduce test noise with smart output filtering
|
|
|
|
## Summary
|
|
|
|
Add PostToolUse hooks that filter test output to show only what matters - failures and summaries, not passing tests.
|
|
|
|
## Problem
|
|
|
|
When running `core go test` or `core php test`, the full output floods the context:
|
|
- Hundreds of "PASS" lines for passing tests
|
|
- Verbose coverage output
|
|
- Repetitive timing information
|
|
|
|
This wastes context window and makes failures harder to spot.
|
|
|
|
## Solution
|
|
|
|
PostToolUse hooks that:
|
|
1. Parse test output
|
|
2. Extract only failures, errors, and summary
|
|
3. Return filtered output as `additionalContext`
|
|
4. Use `suppressOutput: true` to hide the verbose original
|
|
|
|
## Hook Configuration
|
|
|
|
```json
|
|
{
|
|
"hooks": {
|
|
"PostToolUse": [
|
|
{
|
|
"matcher": "Bash",
|
|
"hooks": [
|
|
{
|
|
"type": "command",
|
|
"command": "core ai filter test-output"
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
}
|
|
```
|
|
|
|
## Filter Logic
|
|
|
|
**Go tests:**
|
|
- Show: FAIL, ERROR, panic, --- FAIL
|
|
- Hide: PASS, RUN, coverage lines (unless requested)
|
|
- Summary: "47 passed, 2 failed, 1 skipped"
|
|
|
|
**PHP/Pest tests:**
|
|
- Show: ✗, FAIL, Error, Exception
|
|
- Hide: ✓, passing test names
|
|
- Summary: "Tests: 47 passed, 2 failed"
|
|
|
|
**Lint output:**
|
|
- Show: actual errors/warnings with file:line
|
|
- Hide: "no issues found" for each file
|
|
- Summary: "3 issues in 2 files"
|
|
|
|
## Output Format
|
|
|
|
```json
|
|
{
|
|
"suppressOutput": true,
|
|
"hookSpecificOutput": {
|
|
"hookEventName": "PostToolUse",
|
|
"additionalContext": "## Test Results\n\n✗ 2 failed, 47 passed\n\n### Failures:\n- TestFoo: expected 5, got 3\n- TestBar: nil pointer"
|
|
}
|
|
}
|
|
```
|
|
|
|
## Command Detection
|
|
|
|
Only filter when command matches:
|
|
- `core go test*`
|
|
- `core php test*`
|
|
- `core go lint*`
|
|
- `core php stan*`
|
|
- `core qa*`
