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

                    ▲
                   /A\
                  / B \      A/B测试(少量,耗时)
                 /测试  \
                /─────────\
               /  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。

2.2 测试框架定义

test_framework:
  name: skills-test
  version: 1.0.0
  
  test_suites:
    - name: unit_tests
      description: 单元测试套件
      match_pattern: "**/tests/unit/**/*.test.yaml"
      execution:
        parallel: true
        max_workers: 4
        
    - name: integration_tests
      description: 集成测试套件
      match_pattern: "**/tests/integration/**/*.test.yaml"
      execution:
        parallel: false
        
  assertions:
    - type: exact_match

    - type: contains
      description: 包含指定内容
      
    - type: regex
      description: 正则表达式匹配
      
    - type: schema
      description: JSON Schema验证
      
    - type: llm_judge
      description: AI辅助评判

  id: TC-001
  name: 代码审查Skill基本功能测试
  skill: SKILL.code-reviewer
  priority: high
  
  test_data:
    input:
      code: |
        function add(a, b) {
          return a + b;
        }
      language: javascript

      - no_errors
      
    manual_review:
      - output_quality

正常输入测试

test_case:
  id: TC-002
  name: 正常输入测试
  
  test_data:
    input:
      prompt: "解释什么是Python中的列表推导式"
      
  assertions:
    - type: contains
      value: "列表推导式"
    - type: contains
      value: "Python"
    - type: schema
      value:
        type: object
        properties:
          explanation: {type: string}
          example: {type: string}
        required: [explanation, example]

边界输入测试

test_case:
  id: TC-003
  name: 边界输入测试 - 空输入

    input:
      prompt: ""
      
  expected_behavior:
    - type: reject
      reason: "输入不能为空"
    - type: response
      message: "请提供有效的问题"

异常输入测试

test_case:
  id: TC-004
  name: 异常输入测试 - 无效格式
  
  test_data:
    input:
      prompt: "生成一个JSON格式的用户信息,但内容是纯文本"
      
  expected_behavior:
    - type: correct_formatting
      format: json
    - type: content_extraction
      strategy: try_parse_and_fix

2.4 测试执行与报告

test_execution:
  environment:
    node: node-001
    memory: 4GB
    timeout: 30000
    
  reporting:
    formats:
      - json
      - html
      - junit_xml
      
    metrics:
      - pass_rate
      - avg_duration
      - flaky_tests
      - coverage

Note

测试报告应该包含足够的调试信息,便于快速定位失败的测试用例。建议在报告中包含完整的输入、输出和差异对比。


集成测试

  skills_involved:
    - SKILL.document-parser
    - SKILL.content-classifier
    - SKILL.summarizer
    
  test_flow:
    - step: 1
      skill: SKILL.document-parser
      input:
        document: sample.pdf
      expected:
        output_type: text
        content_length: "> 100"
        
    - step: 2
      skill: SKILL.content-classifier
      input:
        source: "step1.output"
      expected:
        category: "technical|business|legal"
        
    - step: 3
      skill: SKILL.summarizer
      input:
        source: "step1.output"
        type: "step2.category"
      expected:
        length: "< 500"

      expected:
        error_reported: true
        partial_output: true
        
    - name: 全步骤跳过
      input:
        data: ""
      expected:
