测试策略概述
1.1 测试的重要性
Skills作为AI应用的核心组件,其质量直接影响用户体验和系统稳定性。不同于传统软件的确定性输出,Skills的输出具有概率性和多样性,这使得测试更具挑战性。
Skills测试的核心挑战:
输出多样性:同样的输入可能产生多种合理的输出,难以定义”正确”标准。
上下文依赖:Skills的表现受对话历史、用户偏好等上下文因素影响。
质量主观性:某些输出质量(如”写得更好”)具有主观性,难以自动化评判。
组合效应:多个Skills组合时,可能产生意想不到的交互效果。
1.2 测试金字塔

/ 集成测试 \ 集成测试(适量)
/─────────────\
/ 单元测试 \ 单元测试(大量,快速)

单元测试:测试单个Skill的基本功能,覆盖核心能力。
集成测试:测试多个Skills之间的协作,验证接口和流程。
A/B测试:在真实环境中对比不同版本的效果差异。
Tip
在Skills开发的早期阶段,应该投入更多精力在单元测试上。随着系统成熟,逐步增加集成测试和A/B测试的比重。
单元测试设计
2.1 测试用例设计原则
单元测试应该覆盖以下维度:
功能覆盖:每个Skill的核心功能都有对应的测试用例。
输入覆盖:覆盖正常输入、边界输入、异常输入。
输出验证:验证输出的格式、类型和内容符合预期。
