|
||||
|
||||
**Category**: instantiation
|
||||
**Description**: Instantiate Database: Test database connection
|
||||
**Expected**: self.assertTrue(db.connect())
|
||||
**Confidence**: 0.85

|
||||
```
|
||||
|
||||
*Source: tests/test_db.py:15*
|
||||
```
|
||||
|
||||
## Extraction Categories
|
||||
|
||||
### 1. Instantiation
|
||||
|
||||
**Extracts**: Object creation with real parameters
|
||||
|
||||
```python
|
||||
# Example from test
|
||||
db = Database(
|
||||
host="localhost",
|
||||
port=5432,
|
||||
user="admin",
|
||||
password="secret"
|
||||
)
|
||||
```
|
||||
|
||||
**Use Case**: Shows valid initialization parameters
|
||||
|
||||
### 2. Method Call
|
||||
|
||||
**Extracts**: Method calls followed by assertions
|
||||
|
||||
```python
|
||||
# Example from test
|
||||
response = api.get("/users/1")
|
||||
assert response.status_code == 200
|
||||
```
|
||||
|
||||
**Use Case**: Demonstrates expected behavior
|
||||
|
||||
### 3. Config
|
||||
|
||||
**Extracts**: Configuration dictionaries (2+ keys)
|
||||
|
||||
```python
|
||||
# Example from test
|
||||
config = {
|
||||
"debug": True,
|
||||
"database_url": "postgresql://localhost/test",
|
||||
"cache_enabled": False
|
||||
}
|
||||
```
|
||||
|
||||
**Use Case**: Shows valid configuration examples
|
||||
|
||||
### 4. Setup
|
||||
|
||||
**Extracts**: setUp() methods and pytest fixtures
|
||||
|
||||
```python
|
||||
# Example from setUp
|
||||
self.client = APIClient(api_key="test-key")
|
||||
self.client.connect()
|
||||
```
|
||||
|
||||
**Use Case**: Demonstrates initialization sequences
|
||||
|
||||
### 5. Workflow
|
||||
|
||||
**Extracts**: Multi-step integration tests (3+ steps)
|
||||
|
||||
```python
|
||||
# Example workflow
|
||||
user = User(name="John", email="john@example.com")
|
||||
user.save()
|
||||
user.verify()
|
||||
session = user.login(password="secret")
|
||||
assert session.is_active
|
||||
```
|
||||
|
||||
**Use Case**: Shows complete usage patterns
|
||||
|
||||
## Quality Filtering
|
||||
|
||||
### Confidence Scoring (0.0 - 1.0)
|
||||
|
||||
- **Instantiation**: 0.8 (high - clear object creation)
|
||||
- **Method Call + Assertion**: 0.85 (very high - behavior proven)
|
||||
- **Config Dict**: 0.75 (good - clear configuration)
|
||||
- **Workflow**: 0.9 (excellent - complete pattern)
|
||||
|
||||
### Automatic Filtering
|
||||
|
||||
**Removes**:
|
||||
- Trivial patterns: `assertTrue(True)`, `assertEqual(1, 1)`
|
||||
- Mock-only code: `Mock()`, `MagicMock()`
|
||||
- Too short: < 20 characters
|
||||
- Empty constructors: `MyClass()` with no parameters
|
||||
|
||||
**Adjustable Thresholds**:
|
||||
```bash
|
||||
# High confidence only (0.7+)
|
||||
--min-confidence 0.7
|
||||
|
||||
# Allow lower confidence for discovery
|
||||
--min-confidence 0.4
|
||||
```
|
||||
|
||||
## Use Cases
|
||||
|
||||
### 1. Enhanced Documentation
|
||||
|
||||
**Problem**: Documentation often lacks real usage examples
|
||||
|
||||
**Solution**: Extract examples from working tests
|
||||
|
||||
```bash
|
||||
# Generate examples for SKILL.md
|
||||
skill-seekers extract-test-examples tests/ --markdown >> SKILL.md
|
||||
```
|
||||
|
||||
### 2. API Understanding
|
||||
|
||||
**Problem**: New developers struggle with API usage
|
||||
|
||||
**Solution**: Show how APIs are actually tested
|
||||
|
||||
### 3. Tutorial Generation
|
||||
|
||||
**Problem**: Creating step-by-step guides is time-consuming
|
||||
|
||||
**Solution**: Use workflow examples as tutorial steps
|
||||
|
||||
### 4. Configuration Examples
|
||||
|
||||
**Problem**: Valid configuration is unclear
|
||||
|
||||
**Solution**: Extract config dictionaries from tests
|
||||
|
||||
## Architecture
|
||||
|
||||
### Core Components
|
||||
|
||||
```
|
||||

|
||||
├── PythonTestAnalyzer (AST-based)
|
||||
│ ├── extract_from_test_class()

|
||||
└── _is_trivial()
|
||||
```
|
||||
|
||||
### Data Flow
|
||||
|
||||
1. **Find Test Files**: Glob patterns (test_*.py, *_test.go, etc.)
|
||||
2. **Detect Language**: File extension mapping
|
||||
3. **Extract Examples**:
|
||||
- Python → PythonTestAnalyzer (AST)
|
||||
- Others → GenericTestAnalyzer (Regex)
|
||||
4. **Apply Quality Filter**: Remove trivial patterns
|
||||
5. **Limit Per File**: Top N by confidence
|
||||
6. **Generate Report**: JSON or Markdown
|
||||
|
||||
## Limitations
|
||||
|
||||
### Current Scope
|
||||
|
||||
- **Python**: Full AST-based extraction (all categories)
|
||||
- **Other Languages**: Regex-based (limited to common patterns)
|
||||
- **Focus**: Test files only (not production code)
|
||||
- **Complexity**: Simple to moderate test patterns
|
||||
|
||||
### Not Extracted
|
||||
|
||||
- Complex mocking setups
|
||||
- Parameterized tests (partial support)
|
||||
- Nested helper functions
|
||||
- Dynamically generated tests
|
||||
|
||||
### Future Enhancements (Roadmap C3.3-C3.5)
|
||||
|
||||
- C3.3: Build 'how to' guides from workflow examples
|
||||
- C3.4: Extract configuration patterns
|
||||
- C3.5: Architectural overview from test coverage
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### No Examples Extracted
|
||||
|
||||
**Symptom**: `total_examples: 0`
|
||||
|
||||
**Causes**:
|
||||
1. Test files not found (check patterns: test_*.py, *_test.go)
|
||||
2. Confidence threshold too high
|
||||
3. Language not supported
|
||||
|
||||
**Solutions**:
|
||||
```bash
|
||||
# Lower confidence threshold
|
||||
--min-confidence 0.3
|
||||
|
||||
# Check test file detection
|
||||
ls tests/test_*.py
|
||||
|
||||
# Verify language support
|
||||
--language python # Use supported language
|
||||
```
|
||||
|
||||
### Low Quality Examples
|
||||
|
||||
**Symptom**: Many trivial or incomplete examples
|
||||
|
||||
**Causes**:
|
||||
1. Tests use heavy mocking
|
||||
2. Tests are too simple
|
||||
3. Confidence threshold too low
|
||||
|
||||
**Solutions**:
|
||||
```bash
|
||||
# Increase confidence threshold
|
||||
--min-confidence 0.7
|
||||
|
||||
# Reduce examples per file (get best only)
|
||||
--max-per-file 3
|
||||
```
|
||||
|
||||
### Parsing Errors
|
||||
|
||||
**Symptom**: `Failed to parse` warnings
|
||||
|
||||
**Causes**:
|
||||
1. Syntax errors in test files
|
||||
2. Incompatible Python version
|
||||
3. Dynamic code generation
|
||||
|
||||
**Solutions**:
|
||||
- Fix syntax errors in test files
|
||||
- Ensure tests are valid Python/JS/Go code
|
||||
- Errors are logged but don't stop extraction
|
||||
|
||||
## Examples
|
||||
|
||||
### Python unittest
|
||||
|
||||
```python
|
||||
# tests/test_database.py
|
||||
import unittest
|
||||
|
||||
class TestDatabase(unittest.TestCase):
|
||||
def test_connection(self):
|
||||
"""Test database connection with real params"""
|
||||
db = Database(
|
||||
host="localhost",
|
||||
port=5432,
|
||||
user="admin",
|
||||
timeout=30
|
||||
)
|
||||
self.assertTrue(db.connect())
|
||||
```
|
||||
|
||||
**Extracts**:
|
||||
- Category: instantiation
|
||||
- Code: `db = Database(host="localhost", port=5432, user="admin", timeout=30)`
|
||||
- Confidence: 0.8
|
||||
- Expected: `self.assertTrue(db.connect())`
|
||||
|
||||
### Python pytest
|
||||
|
||||
```python
|
||||
# tests/test_api.py
|
||||
import pytest
|
||||
|
||||
@pytest.fixture
|
||||
def client():
|
||||
return APIClient(base_url="https://api.test.com")
|
||||
|
||||
def test_get_user(client):
|
||||
"""Test fetching user data"""
|
||||
response = client.get("/users/123")
|
||||
assert response.status_code == 200
|
||||
assert response.json()["id"] == 123
|
||||
```
|
||||
|
||||
**Extracts**:
|
||||
- Category: method_call
|
||||
- Setup: `# Fixtures: client`
|
||||
- Code: `response = client.get("/users/123")\nassert response.status_code == 200`
|
||||
- Confidence: 0.85
|
||||
|
||||
### Go Table Test
|
||||
|
||||
```go
|
||||
// add_test.go
|
||||
func TestAdd(t *testing.T) {
|
||||
calc := Calculator{mode: "basic"}
|
||||
result := calc.Add(2, 3)
|
||||
if result != 5 {
|
||||
t.Errorf("Add(2, 3) = %d; want 5", result)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Extracts**:
|
||||
- Category: instantiation
|
||||
- Code: `calc := Calculator{mode: "basic"}`
|
||||
- Confidence: 0.6
|
||||
|
||||
## Performance
|
||||
|
||||
| Metric | Value |
|
||||
|--------|-------|
|
||||
| Processing Speed | ~100 files/second (Python AST) |
|
||||
| Memory Usage | ~50MB for 1000 test files |
|
||||
| Example Quality | 80%+ high-confidence (>0.7) |
|
||||
| False Positives | <5% (with default filtering) |
|
||||
|
||||
