通过率门禁设置

测试通过率是衡量代码质量的直接指标，合理的通过率门禁能够确保只有经过充分测试的代码才能进入后续流程。

通过率指标定义

单元测试通过率

单元测试通过率衡量单元测试的执行情况，是代码质量的基础指标。通常要求单元测试通过率达到100%。

集成测试通过率

集成测试通过率衡量组件间集成测试的执行情况。由于集成测试涉及外部依赖，可以设置略低于100%的通过率要求。

端到端测试通过率

端到端测试通过率衡量系统整体功能的测试情况。由于端到端测试容易受环境因素影响，可以根据实际情况设置合理的通过率阈值。

动态门禁调整

随着项目的发展和团队成熟度的提升，质量门禁的要求也需要动态调整，以适应不同的发展阶段。

门禁成熟度模型

初级阶段门禁

在项目初期或团队成熟度较低时，可以设置相对宽松的门禁要求，重点在于建立测试文化和流程。

{
  "maturity_level": "beginner",
  "coverage_thresholds": {
    "line_coverage": 0.60,
    "branch_coverage": 0.50
  },
  "pass_rate_thresholds": {
    "overall": 0.90,
    "critical_suites": 0.95
  },
  "warning_only": true
}

中级阶段门禁

在团队具备一定测试基础后，可以逐步提高门禁要求，推动质量提升。

{
  "maturity_level": "intermediate",
  "coverage_thresholds": {
    "line_coverage": 0.75,
    "branch_coverage": 0.65,
    "function_coverage": 0.70
  },
  "pass_rate_thresholds": {
    "overall": 0.95,
    "critical_suites": 1.0
  },
  "warning_only": false
}

高级阶段门禁

在团队成熟度较高时，可以设置严格的门禁要求，确保高质量交付。

{
  "maturity_level": "advanced",
  "coverage_thresholds": {
    "line_coverage": 0.85,
    "branch_coverage": 0.80,
    "function_coverage": 0.85,
    "instruction_coverage": 0.85
  },
  "pass_rate_thresholds": {
    "overall": 0.98,
    "critical_suites": 1.0
