Core Implementation Patterns
1. Abstract Base Reporter Pattern
from abc import ABC, abstractmethod
from typing import Any, Dict, List, Optional
from datetime import datetime
import time
class BaseReporter(ABC):
"""Abstract base for all test reporters with common functionality."""
def __init__(self, test_name: str):
self.test_name = test_name
self.start_time = time.time()
self.data = {
"inputs": {},
"processing_steps": [],
"outputs": {},
"quality_metrics": {},
"assertions": [],
"errors": []
}
@abstractmethod
async def finalize(self, output_path: Optional[str] = None) -> Dict[str, Any]:
"""Generate final test report - must be implemented by concrete classes."""
pass
2. Gruvbox Terminal Aesthetic Implementation
def generate_gruvbox_html_report(self) -> str:
"""Generate HTML report with gruvbox terminal aesthetic."""
return f"""<!DOCTYPE html>
<html lang="en">
<head>
<style>
body {{
font-family: 'Monaco', 'Menlo', 'Ubuntu Mono', 'Consolas', monospace;

3. Quality Metrics Engine
class QualityMetrics:
"""Comprehensive quality assessment for test results."""
def calculate_overall_score(self, test_data: Dict[str, Any]) -> float:
"""Calculate overall quality score (0-10)."""
scores = []
# Functional quality (40% weight)
functional_score = self._calculate_functional_quality(test_data)
scores.append(functional_score * 0.4)
# Performance quality (25% weight)
performance_score = self._calculate_performance_quality(test_data)
scores.append(performance_score * 0.25)
# Code coverage quality (20% weight)
coverage_score = self._calculate_coverage_quality(test_data)
scores.append(coverage_score * 0.2)
# Report quality (15% weight)
report_score = self._calculate_report_quality(test_data)
scores.append(report_score * 0.15)
return sum(scores)
4. SQLite Integration Pattern
class DatabaseManager:
"""Manage SQLite database for test history tracking."""
def __init__(self, db_path: str = "mcplaywright_test_registry.db"):
self.db_path = db_path
self._initialize_database()
def register_test_report(self, report_data: Dict[str, Any]) -> str:
"""Register test report and return unique ID."""
report_id = f"test_{int(time.time())}_{random.randint(1000, 9999)}"
conn = sqlite3.connect(self.db_path)
cursor = conn.cursor()
cursor.execute("""
INSERT INTO test_reports
(report_id, test_name, test_type, timestamp, duration,
success, quality_score, file_path, metadata_json)
VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)
""", (
report_id,
report_data["test_name"],
report_data["test_type"],
report_data["timestamp"],
report_data["duration"],
report_data["success"],
report_data["quality_score"],
report_data["file_path"],
json.dumps(report_data.get("metadata", {}))
))
conn.commit()
conn.close()
return report_id
🎨 Aesthetic Implementation Guidelines
Gruvbox Color Palette
GRUVBOX_COLORS = {
'dark0': '#282828', # Main background
'dark1': '#3c3836', # Secondary background
'dark2': '#504945', # Border color
'light0': '#ebdbb2', # Main text
'light1': '#d5c4a1', # Secondary text
'light4': '#928374', # Muted text
'red': '#fb4934', # Error states
'green': '#b8bb26', # Success states
'yellow': '#fabd2f', # Warning/stats
'blue': '#83a598', # Headers/links
'purple': '#d3869b', # Accents
'aqua': '#8ec07c', # Info states
'orange': '#fe8019' # Commands/prompts
}
Terminal Status Line Pattern
def generate_status_line(self, test_data: Dict[str, Any]) -> str:
"""Generate vim-style status line for reports."""
total_tests = len(test_data.get('assertions', []))
passed_tests = sum(1 for a in test_data.get('assertions', []) if a['passed'])
success_rate = (passed_tests / total_tests * 100) if total_tests > 0 else 0
return f"NORMAL | MCPlaywright v1.0 | tests/{total_tests} | {success_rate:.0f}% pass rate"
Command Line Aesthetic
def format_command_display(self, command: str) -> str:
"""Format commands with terminal prompt styling."""
return f"""
<div class="command-line">{command}</div>
"""
🔧 Implementation Best Practices
1. Zero-Configuration Setup
class TestFramework:
"""Main framework class with zero-config defaults."""
def __init__(self, config: Optional[Dict[str, Any]] = None):
self.config = self._merge_with_defaults(config or {})
self.reports_dir = Path(self.config.get('reports_dir', 'reports'))
self.reports_dir.mkdir(parents=True, exist_ok=True)
def _merge_with_defaults(self, user_config: Dict[str, Any]) -> Dict[str, Any]:
defaults = {
'theme': 'gruvbox',
'output_format': 'html',
'parallel_execution': True,
'quality_threshold': 8.0,
'auto_open_reports': True,
'database_tracking': True
}
return {**defaults, **user_config}
2. Comprehensive Error Handling
class TestExecution:
"""Robust test execution with comprehensive error handling."""
async def run_test_safely(self, test_func, *args, **kwargs):
"""Execute test with proper error handling and reporting."""
try:
start_time = time.time()
result = await test_func(*args, **kwargs)
duration = time.time() - start_time
return {
'success': True,
'result': result,
'duration': duration,
'error': None
}
except Exception as e:
duration = time.time() - start_time
self.reporter.log_error(e, f"Test function: {test_func.__name__}")
return {
'success': False,
'result': None,
'duration': duration,
'error': str(e)
}
3. Parallel Test Execution
import asyncio
import concurrent.futures
from typing import List, Callable
class ParallelTestRunner:
"""Execute tests in parallel while maintaining proper reporting."""
async def run_tests_parallel(self, test_functions: List[Callable],
max_workers: int = 4) -> List[Dict[str, Any]]:
"""Run multiple tests concurrently."""
semaphore = asyncio.Semaphore(max_workers)
async def run_single_test(test_func):
async with semaphore:
return await self.run_test_safely(test_func)
tasks = [run_single_test(test_func) for test_func in test_functions]
results = await asyncio.gather(*tasks, return_exceptions=True)
return results
📊 Quality Metrics Implementation
Quality Score Calculation
def calculate_quality_scores(self, test_data: Dict[str, Any]) -> Dict[str, float]:
"""Calculate comprehensive quality metrics."""
return {
'functional_quality': self._assess_functional_quality(test_data),
'performance_quality': self._assess_performance_quality(test_data),
'code_quality': self._assess_code_quality(test_data),
'aesthetic_quality': self._assess_aesthetic_quality(test_data),
'documentation_quality': self._assess_documentation_quality(test_data)
}
def _assess_functional_quality(self, test_data: Dict[str, Any]) -> float:
"""Assess functional test quality (0-10)."""
assertions = test_data.get('assertions', [])
if not assertions:
return 0.0
passed = sum(1 for a in assertions if a['passed'])
base_score = (passed / len(assertions)) * 10
# Bonus for comprehensive testing
if len(assertions) >= 10:
base_score = min(10.0, base_score + 0.5)
# Penalty for errors
errors = len(test_data.get('errors', []))
if errors > 0:
base_score = max(0.0, base_score - (errors * 0.5))
return base_score
🚀 Usage Examples
Basic Test Implementation
from testing_framework.reporters.browser_reporter import BrowserTestReporter
from testing_framework.fixtures.browser_fixtures import BrowserFixtures
class TestDynamicToolVisibility:
def __init__(self):
self.reporter = BrowserTestReporter("dynamic_tool_visibility_test")
self.test_scenario = BrowserFixtures.tool_visibility_scenario()
async def run_complete_test(self):
try:
# Setup test
self.reporter.log_test_start(
self.test_scenario["name"],
self.test_scenario["description"]
)
# Execute test steps
results = []
results.append(await self.test_initial_state())
results.append(await self.test_session_creation())
results.append(await self.test_recording_activation())
# Generate report
overall_success = all(results)
html_report = await self.reporter.finalize()
return {
'success': overall_success,
'report_path': html_report['file_path'],
'quality_score': html_report['quality_score']
}
except Exception as e:
self.reporter.log_error(e)
return {'success': False, 'error': str(e)}
Unified Test Runner
async def run_all_tests():
"""Execute complete test suite with beautiful reporting."""
test_classes = [
TestDynamicToolVisibility,
TestSessionLifecycle,
TestMultiBrowser,
TestPerformance,
TestErrorHandling
]
results = []
for test_class in test_classes:
test_instance = test_class()
result = await test_instance.run_complete_test()
results.append(result)
# Generate index dashboard
generator = TestIndexGenerator()
index_path = generator.generate_and_save_index()
print(f"✅ All tests completed!")
print(f"📊 Dashboard: {index_path}")
return results
