重要说明 (Living Document)
这是一个持续演进的技能文件 (Living Skill)
每次测试会话结束后,必须将新发现的 selector、时序问题、已知坑点追加到.agent/learnings/playwright-tests.md。
每次新会话开始前,必须先读取该文件,避免重复踩坑。
本文件本身也应在发现重大 UI 变化时更新(例如 OWUI 版本升级导致 selector 失效)。
配套 Agent: plugin-tester.agent.md — 完整的部署+测试+学习闭环。
Env 文件: .github/agents/.env.openwebui (OPENWEBUI_URL / USERNAME / PASSWORD)
Scripts Env: scripts/.env (api_key + url,用于 Python 部署脚本)
Instructions
Use Playwright browser tools to test and debug OpenWebUI plugins. Start every session with the login flow. Credentials and URL are read from .github/agents/.env.openwebui.
第一步:登录(每次会话必须先执行)
const fs = require('fs');
const path = require('path');
// 读取 .env.openwebui
function loadEnv() {
const envPath = path.join(process.cwd(), '.github/agents/.env.openwebui');
const raw = fs.readFileSync(envPath, 'utf-8');
const env = {};
for (const line of raw.split('\n')) {
const trimmed = line.trim();
if (!trimmed || trimmed.startsWith('#')) continue;
const [key, ...rest] = trimmed.split('=');
env[key.trim()] = rest.join('=').trim();
}
return env;
}
const env = loadEnv();
const BASE_URL = env.OPENWEBUI_URL || 'http://localhost:3000';
// 导航到登录页
await page.goto(`${BASE_URL}/auth`, { waitUntil: 'networkidle' });
// 检查是否已登录(已登录则跳过)
const isLoggedIn = await page.locator('[id="chat-textarea"], [placeholder*="message" i], div[contenteditable]').count();
if (!isLoggedIn) {
// 填写 email
await page.locator('input[name="email"], input[autocomplete="username"], input[type="email"]').first().fill(env.OPENWEBUI_USERNAME);
// 填写密码
await page.locator('input[type="password"]').first().fill(env.OPENWEBUI_PASSWORD);
// 点击登录
await page.locator('button[type="submit"]').first().click();
// 等待登录完成
await page.waitForURL(`${BASE_URL}/**`, { timeout: 10000 });
await page.waitForTimeout(1500);
}
console.log('✅ 已登录 OpenWebUI:', await page.title());
常用操作模式
截图存档
await page.screenshot({ path: '/tmp/owui-before-fix.png' });
控制台 / 错误捕获
const errors = [];
page.on('console', m => { if (m.type() === 'error') errors.push(m.text()); });
page.on('pageerror', err => errors.push('pageerror: ' + err.message));
await page.waitForTimeout(2000);
console.log('Console errors:', errors);
打开管理员面板(Admin Panel)
const env = loadEnv();
await page.goto(`${env.OPENWEBUI_URL}/admin`, { waitUntil: 'networkidle' });
await page.screenshot({ path: '/tmp/owui-admin.png' });
导航到函数/插件管理(Functions)
const env = loadEnv();
await page.goto(`${env.OPENWEBUI_URL}/admin/functions`, { waitUntil: 'networkidle' });

const editor = page.locator('.cm-content, [contenteditable="true"].CodeMirror').first();
await editor.click();
await page.keyboard.shortcut('Meta+A'); // 全选
await page.keyboard.type(pluginCode); // 粘贴新代码(pluginCode 变量需提前赋值)
发送聊天消息测试插件
const env = loadEnv();
await page.goto(`${env.OPENWEBUI_URL}/`, { waitUntil: 'networkidle' });
// 新建对话
const newChatBtn = page.locator('button').filter({ hasText: /new chat/i }).first();
if (await newChatBtn.count()) await newChatBtn.click();
await page.waitForTimeout(800);
// 输入测试消息
const textarea = page.locator('[id="chat-textarea"], textarea, div[contenteditable]').first();
await textarea.click();
await textarea.fill('你好,请帮我总结这段文字。');
// 发送
const sendBtn = page.locator('button[data-element-id="send-message-button"], button[aria-label*="send" i]').first();
await sendBtn.click();
// 等待回复
await page.waitForSelector('.message-content, [data-role="assistant"]', { timeout: 30000 });
await page.screenshot({ path: '/tmp/owui-chat-response.png' });
触发 Action 插件按钮
// 悬浮消息,查找 Action 按钮(通常在消息底部工具栏)
const msgToolbar = page.locator('.message-toolbar, [class*="action"]').last();
await msgToolbar.hover();
await page.waitForTimeout(300);
// 点击目标 Action 按钮(按图标或 title 过滤)
const actionBtn = page.locator('button[title], button.action-button').filter({ hasText: /export|mind|思维|导出/i }).first();
await actionBtn.click();
await page.waitForTimeout(2000);
await page.screenshot({ path: '/tmp/owui-action-result.png' });
检查 Action 插件的 HTML 输出(iframe / html code block)
// Action 插件通常在消息中输出 HTML 块
const htmlBlock = page.locator('iframe, .plugin-output, code[class*="html"]').last();
const count = await htmlBlock.count();
console.log('HTML output blocks found:', count);
if (count > 0) {
// 截取 iframe 内容
const frame = page.frameLocator('iframe').last();
const frameContent = await frame.locator('body').innerHTML();
console.log('iframe body (first 500):', frameContent.substring(0, 500));
await page.screenshot({ path: '/tmp/owui-plugin-html-output.png' });
}
拦截网络失败请求
const failedRequests = [];
page.on('requestfailed', r => failedRequests.push({ url: r.url(), error: r.failure()?.errorText }));
await page.waitForTimeout(3000);
console.log('Failed requests:', failedRequests);
获取当前页面文本摘要
const bodyText = await page.evaluate(() => document.body.innerText.substring(0, 800));
console.log('Page content:', bodyText);
检查模型选择器(切换测试模型)
// 点击模型选择按钮(顶部)
const modelSelector = page.locator('button').filter({ hasText: /model|gpt|claude|llama/i }).first();
await modelSelector.click();
await page.waitForTimeout(500);
// 从下拉列表中选择目标模型
const targetModel = page.locator('[role="option"], li').filter({ hasText: 'gpt-4' }).first();
await targetModel.click();
await page.waitForTimeout(500);
刷新页面
await page.goto(page.url(), { waitUntil: 'networkidle' });
全流程回归探针(Plugin E2E Probe)
// 捕获所有错误 + 失败请求
await page.evaluate(() => {
window.__pluginBugLogs = { errors: [], failedRequests: [] };
window.addEventListener('error', (e) => {
window.__pluginBugLogs.errors.push(String(e.message || 'unknown'));
});
window.addEventListener('unhandledrejection', (e) => {
window.__pluginBugLogs.errors.push(String(e.reason || 'rejection'));
});
const origFetch = window.fetch.bind(window);
window.fetch = async (...args) => {
const res = await origFetch(...args);
if (!res.ok) window.__pluginBugLogs.failedRequests.push(`${res.status} ${String(args[0])}`);
return res;
};
});
// 触发 Action 按钮
const actionBtn = page.locator('button').filter({ hasText: /export|导出/i }).first();
await actionBtn.click();
await page.waitForTimeout(3000);
// 收集日志
const bugLogs = await page.evaluate(() => window.__pluginBugLogs);
console.log('E2E Probe Result:', JSON.stringify(bugLogs, null, 2));
await page.screenshot({ path: '/tmp/owui-e2e-probe.png' });
自我学习协议(Self-Learning Protocol)
每次会话结束前,执行以下步骤:
Step 1 — 读取现有知识(会话开始时)
// 在执行任何测试前,读取 .agent/learnings/playwright-tests.md
// 提取:已知 selector、已验证用例、已知坑点
const fs = require('fs');
const learningsPath = '.agent/learnings/playwright-tests.md';
if (fs.existsSync(learningsPath)) {
const knowledge = fs.readFileSync(learningsPath, 'utf-8');
console.log('📚 Loaded learnings:', knowledge.substring(0, 300));
}
Step 2 — 记录新发现(会话结束后)
使用 AI 工具或 fs.appendFileSync 将以下内容追加到 .agent/learnings/playwright-tests.md:
- ✅ 新发现的可靠 selector(含日期和插件类型)
- ❌ 已失效的 selector(含失效原因)
- ⚡ 时序敏感点(需要
waitForTimeout的场景) - 🐛 已发现的 UI bug(含截图路径)
- 🧪 新增测试用例(描述 + 结果)
与 Scripts 集成(Deploy + Test 联动)
在 playwright 测试前,可先用 Python 脚本部署插件:
# 部署单类型插件
cd /Users/fujie/app/python/oui/openwebui-extensions
python scripts/install_all_plugins.py --types action
# 部署指定 filter
python scripts/deploy_filter.py async-context-compression
# 验证部署工具可用性
python scripts/verify_deployment_tools.py
scripts/.env 格式(与 playwright env 独立):
api_key=sk-your-api-key
url=http://localhost:3000
