console.log('手动测试清单:', testReport);通过本节兼容性测试方法完整指南的学习,你已经掌握:
A: 根据用户分析数据确定,通常包括Chrome、Firefox、Safari、Edge的最新版本和前1-2个版本。对于企业应用,可能还需要考虑IE11。建议使用Google Analytics等工具分析实际用户的浏览器分布。
A: 自动化测试适合回归测试和大量重复性测试;手动测试适合用户体验、视觉效果和复杂交互的测试。建议核心功能自动化,用户体验手动验证。
A: 对于需要测试多种浏览器和设备组合的项目,云端测试服务能显著提高效率和覆盖率。成本通常比维护本地测试环境更低,特别适合中小团队。
A: 使用真机测试结合模拟器测试;重点关注触摸交互、屏幕适配、性能表现;使用Chrome DevTools的设备模拟功能进行初步测试。
A: 根据影响用户数量、功能重要性、修复难度进行排序。核心功能的兼容性问题优先级最高,装饰性功能可以考虑渐进式增强。
