上传测试图片 upload_input driver.find_element(By.CSS_SELECTOR, input[typefile]) upload_input.send_keys(/absolute/path/to/test_data/single_face.jpg) # 等待处理完成 WebDriverWait(driver, 30).until( EC.presence_of_element_located((By.CLASS_NAME, result-container)) ) # 验证结果显示 result_elements driver.find_elements(By.CLASS_NAME, face-box) assert len(result_elements) 1 def test_multiple_image_upload(self, web_driver, test_url): 测试多张图片批量上传 driver web_driver driver.get(test_url) # 启用多选 driver.execute_script( document.querySelector(input[type\file\]).setAttribute(multiple, ) ) # 上传多张图片 upload_input driver.find_element(By.CSS_SELECTOR, input[typefile]) upload_input.send_keys(\n.join([ /absolute/path/to/test_data/image1.jpg, /absolute/path/to/test_data/image2.jpg ])) # 验证批量处理结果 WebDriverWait(driver, 60).until( EC.presence_of_element_located((By.CLASS_NAME, batch-result)) ) results driver.find_elements(By.CLASS_NAME, result-item) assert len(results) 24. 高级测试技巧4.1 使用Fixture管理测试资源Pytest的fixture功能可以很好地管理测试资源和状态# conftest.py import pytest import requests from selenium import webdriver from selenium.webdriver.chrome.service import Service from webdriver_manager.chrome import ChromeDriverManager pytest.fixture(scopesession) def base_url(): 返回测试环境的基础URL return http://localhost:7860 pytest.fixture def web_driver(): 创建并返回WebDriver实例 options webdriver.ChromeOptions() options.add_argument(--headless) # 无头模式适合CI环境 options.add_argument(--no-sandbox) options.add_argument(--disable-dev-shm-usage) driver webdriver.Chrome( serviceService(ChromeDriverManager().install()), optionsoptions ) yield driver driver.quit() pytest.fixture def test_image(tmp_path): 创建临时测试图片 # 这里可以生成或复制测试图片到临时路径 test_image_path tmp_path / test_face.jpg # 实际使用时需要准备真实的测试图片 return str(test_image_path)4.2 参数化测试和数据驱动利用参数化测试来覆盖多种测试场景# test_api/test_face_recognition.py import pytest class TestFaceRecognition: 人脸识别功能测试 pytest.mark.parametrize(test_image,expected_similarity, [ (same_person_1.jpg, 0.8), (same_person_2.jpg, 0.75), (different_person.jpg, 0.3) ]) def test_face_similarity(self, base_url, test_image, expected_similarity): 测试人脸相似度计算 # 准备测试数据 files { image1: open(ftest_data/{test_image}, rb), image2: open(test_data/reference_face.jpg, rb) } response requests.post(f{base_url}/api/face/compare, filesfiles) result response.json() assert response.status_code 200 assert result[similarity] expected_similarity assert result in result5. 异常测试和边界情况确保系统在异常情况下也能正确处理# test_api/test_error_handling.py import pytest class TestErrorHandling: 异常处理测试 def test_large_file_upload(self, base_url): 测试大文件上传处理 # 创建一个大文件例如10MB的伪图片文件 large_file b\xff\xd8\xff\xe0 b\x00 * (10 * 1024 * 1024) files {image: (large_image.jpg, large_file, image/jpeg)} response requests.post(f{base_url}/api/face/detect, filesfiles) # 应该返回适当的错误响应 assert response.status_code in [413, 400] def test_malformed_request(self, base_url): 测试格式错误的请求 response requests.post( f{base_url}/api/face/detect, data{wrong_param: value}, headers{Content-Type: application/json} ) assert response.status_code 400 pytest.mark.parametrize(invalid_url, [ /api/nonexistent, /api/face/invalid-endpoint, /admin ]) def test_invalid_endpoints(self, base_url, invalid_url): 测试不存在的API端点 response requests.get(f{base_url}{invalid_url}) assert response.status_code 4046. 性能测试确保系统在各种负载下都能保持良好的性能# test_performance/test_response_time.py import time import pytest class TestPerformance: 性能测试类 pytest.mark.performance def test_single_request_response_time(self, base_url): 测试单次请求的响应时间 test_image test_data/single_face.jpg start_time time.time() with open(test_image, rb) as f: files {image: f} response requests.post(f{base_url}/api/face/detect, filesfiles) end_time time.time() response_time end_time - start_time assert response.status_code 200 assert response_time 5.0 # 响应时间应该在5秒以内 pytest.mark.performance def test_concurrent_requests(self, base_url): 测试并发请求处理能力 import concurrent.futures test_image test_data/single_face.jpg def make_request(): with open(test_image, rb) as f: files {image: f} return requests.post(f{base_url}/api/face/detect, filesfiles) # 同时发起10个请求 with concurrent.futures.ThreadPoolExecutor(max_workers10) as executor: futures [executor.submit(make_request) for _ in range(10)] results [future.result() for future in concurrent.futures.as_completed(futures)] # 所有请求都应该成功 assert all(result.status_code 200 for result in results)7. 测试报告和持续集成7.1 生成漂亮的测试报告使用pytest-html生成详细的测试报告pytest --htmlreport.html --self-contained-html7.2 集成到CI/CD流程创建简单的GitHub Actions工作流# .github/workflows/test.yml name: Face Analysis WebUI Tests on: [push, pull_request] jobs: test: runs-on: ubuntu-latest services: webui: image: your-face-analysis-image:latest ports: - 7860:7860 steps: - uses: actions/checkoutv3 - name: Set up Python uses: actions/setup-pythonv4 with: python-version: 3.9 - name: Install dependencies run: | pip install pytest pytest-html requests selenium webdriver-manager - name: Wait for service to be ready run: | until curl -s http://localhost:7860 /dev/null; do sleep 1 done - name: Run tests run: | pytest --htmlreport.html --self-contained-html - name: Upload test report uses: actions/upload-artifactv3 with: name: test-report path: report.html8. 总结搭建一个完整的Face Analysis WebUI测试框架确实需要一些前期投入但长远来看这能为你节省大量的手动测试时间并显著提高代码质量。通过Pytest我们能够创建结构清晰、维护性强的测试套件覆盖API接口、Web界面、异常情况和性能表现等多个方面。实际使用中你可能会发现某些测试需要根据具体的WebUI实现进行调整。比如人脸检测的准确率验证可能需要更复杂的断言逻辑或者性能测试的阈值需要根据实际硬件配置来调整。关键是要保持测试的持续运行和及时更新让自动化测试真正成为开发过程中的可靠安全保障。测试框架搭建好后每次代码变更都能快速验证功能完整性这样你就可以更自信地迭代和发布新功能了。获取更多AI镜像想探索更多AI镜像和应用场景访问 CSDN星图镜像广场提供丰富的预置镜像覆盖大模型推理、图像生成、视频生成、模型微调等多个领域支持一键部署。
