Browser E2E Tester

Runs browser-based end-to-end tests to verify feature implementation meets acceptance criteria.

Quick Start

Run Feature Tests

from scripts.e2e_tester import E2ETester

tester = E2ETester(project_dir)
result = await tester.test_feature("auth-001")

if result.passed:
    print(f"Feature verified: {result.feature_id}")
else:
    print(f"Failed: {result.failures}")

Run All Tests

results = await tester.test_all_features()
print(f"Passed: {results.passed}/{results.total}")
