macos-ui-verify
Testing & QualityUse when you need to visually verify macOS native app UI after fixing bugs, without asking the user to manually test. Triggers when: a UI fix is implemented and needs screenshot-based self-validation; verifying that a visual bug is actually gone (e.g. focus ring, wrong color, missing indicator); closing a feedback loop on Settings/window UI changes in FluxMarkdown or similar macOS apps. Use proactively after ANY SwiftUI or AppKit UI change.

工具选型结论(实测验证)
推荐优先级
| 优先级 | 工具 | 适用场景 | 可靠性 |
|---|---|---|---|
| ✅ 首选 | Swift AX API (ax_click) | 有 label/desc 的 AXButton | 最高,不依赖坐标 |
| ✅ 次选 | osascript click at {x,y} | 有 AX action 但无名称的控件(checkbox、slider) | 高,在 AX 层执行 |
| ✅ 三选 | cgclick(CGEvent 低级点击) | SwiftUI AXGroup(无任何 AX action,如 Theme 选择按钮) | 高,绕过 AX 层直接发硬件事件 |
| ❌ 禁用 | cliclick c:x,y | — | 全部失败(第一次点击只激活窗口) |
| ❌ 不引入 | Appium mac2 | — | SwiftUI Settings 窗口坐标全零,实际失效 |
| ❌ 不引入 | Macaca macOS | — | 本质是 osascript 封装,2023 停维 |
为什么 cliclick 失败?
cliclick 发送硬件级鼠标事件(CGEvent)。macOS 规定:点击 inactive 窗口的第一次点击只激活窗口,不传递到控件。
osascript click at 在 System Events 进程内直接触发 AX Press action,完全绕过窗口激活流程。
为什么需要 cgclick(第三选)?
某些 SwiftUI 控件(如 Settings 里的 Theme 选择按钮)在 AX 树中被标记为 AXGroup 而非 AXButton,没有任何 AX action。
ax_click无效(只搜索 AXButton)osascript click at无效(AXGroup 上没有 Press action 可调用)- 必须绕过 AX 层,使用
CGEvent直接向 HID 层发送鼠标按下/抬起事件 - 前提:应用必须已在前台(先
tell application "FluxMarkdown" to activate)
为什么 Appium mac2 对 Settings 失效?
SwiftUI Settings scene 是辅助窗口(secondary window),WDA 只扫 active 主窗口,Settings 窗口的所有控件坐标返回 {y:982, x:0, w:0, h:0}。
核心工具链
| 工具 | 作用 |
|---|---|
screencapture -l <windowID> | 精确截取指定窗口(不受其他窗口遮挡影响) |
| Swift + CGWindowList | 获取窗口 ID |
Swift AX API (ax_click) | 按名称点击控件(最可靠,首选) |
osascript click at {x,y} | 按坐标点击有 AX action 的控件(次选) |
cgclick(CGEvent 低级点击) | 点击 SwiftUI AXGroup(无 AX action 的控件,第三选) |
osascript | 键盘操作、打开窗口 |
look_at | AI 分析截图内容 |
标准验证循环
1. 确保窗口打开并置前
2. 获取窗口 ID
3. 截图 → look_at 分析
4. 操作 UI(点击/键盘)
5. 再截图 → look_at 验证状态变化
6. 重复直到确认修复
Step 1:获取窗口 ID
cat > /tmp/findwin.swift << 'EOF'
import Cocoa
let wins = CGWindowListCopyWindowInfo(.optionOnScreenOnly, kCGNullWindowID) as! [[String: Any]]
for w in wins {
let owner = w["kCGWindowOwnerName"] as? String ?? ""
let name = w["kCGWindowName"] as? String ?? ""
let wid = w["kCGWindowNumber"] as? Int ?? 0
if owner.contains("FluxMarkdown") || name.contains("设置") {
print("ID=\(wid) Owner=\(owner) Name=\(name)")
}
}
EOF
swiftc /tmp/findwin.swift -o /tmp/findwin && /tmp/findwin
输出示例:ID=1067 Owner=FluxMarkdown Name=FluxMarkdown设置
Step 2:打开目标窗口
# 打开 Settings(Cmd+,)
osascript << 'EOF'
tell application "FluxMarkdown" to activate
delay 0.3
tell application "System Events"
keystroke "," using {command down}
end tell
delay 1.2
EOF
Step 3:精确截图
# 用窗口 ID 截图(不受遮挡影响)
screencapture -l <WINDOW_ID> /tmp/verify_before.png
然后用 look_at 分析:
look_at(
file_path="/tmp/verify_before.png",
goal="描述 Theme 区域三个按钮状态:哪个选中?有无 focus ring 蓝色发光边框?"
)
提问技巧:goal 要具体,指名要检查的元素和症状词(如 "focus ring"、"蓝色发光"、"底部线条")。
Step 4:操作 UI 触发状态变化
推荐方案:Swift AX API(按名称点击,不依赖坐标)
cat > /tmp/ax_click.swift << 'EOF'
import Cocoa

func getAttrStr(_ elem: AXUIElement, _ attr: String) -> String? {

}
func getAttrArr(_ elem: AXUIElement, _ attr: String) -> [AXUIElement]? {
var val: CFTypeRef?
guard AXUIElementCopyAttributeValue(elem, attr as CFString, &val) == .success else { return nil }
return val as? [AXUIElement]
}
func findByDesc(_ elem: AXUIElement, _ target: String, depth: Int = 0) -> AXUIElement? {
guard depth < 12 else { return nil }
let desc = getAttrStr(elem, kAXDescriptionAttribute as String) ?? ""
let role = getAttrStr(elem, kAXRoleAttribute as String) ?? ""
if role == "AXButton" && desc == target { return elem }
if let children = getAttrArr(elem, kAXChildrenAttribute as String) {
for child in children {
if let found = findByDesc(child, target, depth: depth + 1) { return found }
}
}
return nil
}
let apps = NSWorkspace.shared.runningApplications
guard let app = apps.first(where: { $0.localizedName?.contains("FluxMarkdown") == true }) else {
print("not found"); exit(1)
}
let target = CommandLine.arguments.count > 1 ? CommandLine.arguments[1] : ""
let root = AXUIElementCreateApplication(app.processIdentifier)
if let btn = findByDesc(root, target) {
let ok = AXUIElementPerformAction(btn, kAXPressAction as CFString)
print("Click '\(target)': \(ok == .success ? "OK" : "FAIL")")
} else { print("Not found: '\(target)'") }
EOF

CGEvent 低级点击(第三选:SwiftUI AXGroup 无 AX action 的控件)
适用场景:控件在 AX 树中为 AXGroup,没有任何 AX action,ax_click 和 osascript click at 都无效时。

look_at 提问模板
| 场景 | goal 字段 |
|---|---|
| 检查 focus ring | "Theme 三个按钮有无 focus ring 蓝色发光边框?" |
| 检查选中状态 | "哪个按钮被选中?选中态视觉特征(背景色/底部线/边框)?" |
| 检查主题外观 | "页面整体是深色还是浅色主题?代码块背景色是什么?" |
| 检查 UI 元素存在 | "页面是否有重置缩放按钮?在哪里?" |
常见问题
| 问题 | 原因 | 解决 |
|---|---|---|
cliclick 无效 | 第一次点击只激活窗口,不触发控件 | 改用 osascript click at {x,y},永远不用 cliclick |
osascript click at 也无效 | 控件是 AXGroup,没有 AX action | 改用 cgclick(CGEvent),先 activate 应用再点击 |
| 截到错误窗口 | 未用 -l 指定窗口 ID | 必须用 screencapture -l <ID> |
look_at 分析错标签 | 截图时标签未切换完成 | sleep 0.5 后再截图 |
| 窗口 ID 变了 | 窗口重新打开后 ID 会变 | 每次操作前重新运行 findwin |
| ax_click 找不到控件 | 控件没有 desc/label(是 AXGroup) | 用 ax_full 枚举坐标 + cgclick 点击 |
| Appium/WDA 坐标全零 | SwiftUI Settings 是辅助窗口,WDA 不可见 | 不要用 Appium 操作 Settings;用 AX API |
FluxMarkdown 专用:Theme 按钮坐标参考
Theme 选择按钮(AXGroup,无 AX action,必须用 cgclick):
| 按钮 | 中心坐标(Settings 窗口位于 X=438,Y=390 时) |
|---|---|
| Light | 710, 529 |
| Dark | 831, 530 |
| System | 953, 530 |
Toolbar 主题切换按钮 desc 随状态变化(可用 ax_click 按 desc 点击):
| 当前模式 | desc 字段 |
|---|---|
| System | circle.lefthalf.filled |
| Light | 调高亮度 |
| Dark | 勿扰模式 |
⚠️ 坐标与窗口位置相关。若窗口移动,需重新用
ax_full枚举。
验证结论撰写规范
look_at 结果回来后,用以下格式记录:
✅ PASS: [具体观察] — [按钮X选中,无 focus ring,底部线干净]
❌ FAIL: [具体问题] — [按钮X 仍有蓝色发光边框(focus ring 未消除)]
→ 需要修复: [下一步行动]
只有 所有检查项都 ✅ 才能标记 UI 修复完成。
