Agent Testing Framework - AI智能体测试评估框架指南

为什么需要Agent测试框架

凌晨4点17分，你的Agent在生产环境挂了。你排查了3小时才发现是一个Prompt边界条件没处理好。如果早有测试框架，这个问题在开发阶段就能被发现。

Agent Testing Framework的必要性：

• 不确定性高：LLM输出不可预测，需要大量测试覆盖边界
• 环境影响大：不同模型、工具、配置下行为不同
• 用户期望高：用户期望Agent「智能」，但智能需要验证
• 安全风险大：Agent可能执行危险操作，必须预先验证

自动化测试脚本

// OpenClaw Agent测试框架
class AgentTester {
  constructor(agentConfig) {
    this.agent = agentConfig;
    this.testCases = [];
    this.results = [];
  }

  // 加载测试用例
  loadTestCases(cases) {
    this.testCases = cases;
  }

  // 执行测试
  async runTests() {
    for (const testCase of this.testCases) {
      const result = await this.runSingleTest(testCase);
      this.results.push(result);
    }
    return this.generateReport();
  }

  // 单个测试执行
  async runSingleTest(testCase) {
    try {
      // 执行Agent
      const output = await this.agent.execute(testCase.input);
      
      // 验证输出
      const validations = testCase.validation.map(v => 
        this.validate(output, v)
      );
      
      return {
        testCaseId: testCase.id,
        passed: validations.every(v => v.passed),
        output: output,
        validations: validations,
        timestamp: new Date()
      };
    } catch (error) {
      return {
        testCaseId: testCase.id,
        passed: false,
        error: error.message,
        timestamp: new Date()
      };
    }
  }

  // 输出验证
  validate(output, validation) {
    switch (validation.type) {
      case 'keyword_check':
        return {
          passed: output.includes(validation.expected),
          message: validation.expected.every(k => output.includes(k))
        };
      case 'format_check':
        return {
          passed: this.checkFormat(output, validation.expected),
          message: `格式验证`
        };
      default:
        return { passed: true };
    }
  }
}
