What it does
Case Round Trip is an agent skill from DanielSuo117/velocitai. 共享 page 下用例离开起点后必须 UI 返回并断言。触发：往返闭合、case round trip、复位超时、scope 共享 page。
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA. The repository describes itself as: Next-generation UI automation harness powered by Python & Playwright. Chat with AI Agents to seamlessly generate, architect, and execute enterprise-grade UI test code. The licence is MIT.
When your agent uses it
- Testing & QA work in your project
Example prompts
- “/case-round-trip”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- 给每个会"脱离门户布局"的 PageObject 加 click_back_to_()，走真实 UI 返回按钮
- 用例主断言后显式调用返回方法，并再次断言起点页加载
- 复位 fixture 保持最简单形态（仅走门户导航），不做 goto 兜底
What it can do on your machine
Read from SKILL.md and the folder at commit dfcca7e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Case Round Trip loads about 588 tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 127 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- 共享 page 下用例离开起点后必须 UI 返回并断言。触发：往返闭合、case round trip、复位超时、scope 共享 page。
Case Round Trip — 用例往返闭合
仅适用 Playwright + pytest。
核心规则
共享 page（scope > function 的 fixture）下，用例离开起点页后必须在末尾通过真实 UI 返回并断言；不要在复位 fixture 里做 goto 兜底。
何时适用
- 多个用例共享一个 page / browser context（class/module/session scope）
- 用例会进入"脱离门户布局"的页面（子路由、沉浸式页面、跨子域）
- 复位 fixture 依赖门户布局才有的元素（侧边栏 / 顶部 nav）
做法
- 给每个会"脱离门户布局"的 PageObject 加
click_back_to_<landing>()，走真实 UI 返回按钮 - 用例主断言后显式调用返回方法，并再次断言起点页加载
- 复位 fixture 保持最简单形态（仅走门户导航），不做 goto 兜底
def test_enter_detail(self):
self.home.click_first_item()
detail = DetailPage(self.page)
assert detail.is_page_loaded(), "详情页未加载"
detail.click_back_to_home()
assert self.home.is_page_loaded(), "返回起点页失败"起点 is_page_loaded 的严格判据
复位 fixture 通常判断 if not start.is_page_loaded(): start.click_back_to_landing()。若 is_page_loaded() 仅校验"页面骨架可见"（title / 容器），切到其他 tab/子路由后骨架仍在 → 返回 True → 复位永不触发 → 下一用例起点错乱。
规则：起点 PageObject 的 is_page_loaded() 必须包含"当前停留在起点状态"判据（起点 tab 激活态 / 起点 URL / 起点独有内容），而不仅是"骨架存在"。
# ❌ 只校验骨架 — 切到其他 tab 后仍返回 True，复位失效
def is_page_loaded(self) -> bool:
return self.is_visible(self.PAGE_TITLE) and self.is_visible(self.TAB_BAR)
# ✅ 加"当前在起点 tab"判据 — tab 切换后返回 False，触发复位
def is_page_loaded(self) -> bool:
return (
self.is_visible(self.PAGE_TITLE)
and self.is_visible(self.TAB_BAR)
and self.is_visible(self.LANDING_TAB_ACTIVE_MARK) # 关键第 3 条
)LANDING_TAB_ACTIVE_MARK 的 selector 必须用 text= 等锁定到具体起点 tab（如 .tab.active >> text=<起点 tab 名>），否则 .active 会匹配任意激活 tab，同样失效（见 locator-strategy.md 状态类 selector 必须配 text 锁定）。
决策
跳转目标是否仍保留起点页的门户导航？
├─ 是 → 依赖复位 fixture 即可
└─ 否 → PageObject 必须提供返回方法 + 用例末尾显式返回 + 断言❌ 反例
- 进入沉浸式页面后只断言进入，不返回 → 后续用例复位 fixture 点不到门户导航
page.goto(<landing_url>)绕过返回按钮 → 失去对返回按钮的回归覆盖if not visible: goto(...)塞进复位 fixture → 掩盖"用例未闭合"真问题
检查清单
- 跳转目标脱离门户布局 → 本规则适用
- PageObject 提供
click_back_to_<landing>() - 用例末尾调用返回方法并断言起点页加载
- 测试顺序打乱仍全部通过
项目落地参考
项目中脱离门户布局的 PageObject（需实现 click_back_to_<landing>）见 docs/pages-catalog.md 与 docs/regression-points.md（带"⚠️ 跳转目标脱离门户布局"标注的页面）。
