自查清单 (Checklist)

在你认为本 PR 满足被审阅的标准之前，需要确保 / Before you mark the PR ready for review, please make sure that:

• 符合Venus项目管理规范中关于PR的相关标准 / The PR follows the PR standards set out in the Venus project management guidelines
• 具有清晰明确的 commit message / All commits have a clear commit message.
  修改后的 PR 模版中的自查清单
• 包含必要的测试用例 / This PR has tests for new functionality or change in behaviour
• 包含必要的指南或文档 / If new user-facing features are introduced, clear usage guidelines and / or documentation updates should be included
• 通过必要的检查项 / All checks are green

其中 "包含必要的测试用例", "包含必要的指南或文档" 从语义上来说是本次 PR 包含测试用例和文档才需要勾选，但我觉得这两个改成检查项 "包含必要的测试用例或不需要", "包含必要的指南或文档或不需要"，可能更加符合 “自查清单“。
