Core Workflow

核心工作流程

Analyze requirements - Identify user flows to test
Setup - Configure Playwright with proper settings and project structure
Write tests - Use POM pattern, proper selectors, auto-waiting
Debug - Fix flaky tests, use traces
Integrate - Add to CI/CD pipeline

需求分析 - 确定需要测试的用户流程
环境搭建 - 配置Playwright的正确设置和项目结构
编写测试 - 使用POM模式、合适的定位器、自动等待机制
调试 - 修复不稳定测试，使用trace功能
集成 - 接入CI/CD流水线

Constraints

约束规则

MUST DO

必须遵循

Use role-based selectors when possible
Leverage auto-waiting (don't add arbitrary timeouts)
Keep tests independent (no shared state)
Use Page Object Model for maintainability
Enable traces/screenshots for debugging
Run tests in parallel
Separate
```
tests/
```
(specs) from
```
pages/
```
(Page Objects) from
```
fixtures/
```
Use
```
.spec.ts
```
suffix for all test files
Use
```
Page
```
suffix for Page Object classes (e.g.,
```
LoginPage
```
)
Keep
```
playwright.config.ts
```
at the project root
Store static test data in
```
test-data/
```
(never inline large blobs in tests)
Place reusable custom fixtures in
```
fixtures/
```
with
```
.fixture.ts
```
suffix
Always assert HTTP status code before asserting response body in API tests

尽可能使用基于角色的定位器
利用自动等待机制（不要添加任意超时）
保持测试独立性（无共享状态）
使用Page Object Model提升可维护性
启用trace/截图用于调试
并行运行测试
将
```
tests/
```
（测试用例）、
```
pages/
```
（Page Objects）、
```
fixtures/
```
（夹具）分开存放
所有测试文件使用
```
.spec.ts
```
后缀
Page Object类使用
```
Page
```
后缀（例如：
```
LoginPage
```
）
将
```
playwright.config.ts
```
放在项目根目录
静态测试数据存放在
```
test-data/
```
（不要在测试中嵌入大段数据）
可复用的自定义fixtures放在
```
fixtures/
```
目录，使用
```
.fixture.ts
```
后缀
API测试中，必须先断言HTTP状态码，再断言响应体

MUST NOT DO

禁止操作

Use
```
waitForTimeout()
```
(use proper waits)
Rely on CSS class selectors (brittle)
Share state between tests
Ignore flaky tests
Use
```
first()
```
,
```
nth()
```
without good reason
Mix Page Object logic inside spec files
Put test helpers directly in the root directory
Store auth state files (
```
auth.json
```
) in source control
Skip HTTP status assertion in API tests
Use fixed
```
Date.now()
```
thresholds without documented baselines for performance tests

使用
```
waitForTimeout()
```
（应使用合理的等待方式）
依赖CSS类选择器（易失效）
测试间共享状态
忽略不稳定测试
无合理理由使用
```
first()
```
、
```
nth()
```
在测试用例文件中混入Page Object逻辑
将测试辅助工具直接放在根目录
将认证状态文件（
```
auth.json
```
）存入版本控制
API测试中跳过HTTP状态码断言
在性能测试中使用固定的
```
Date.now()
```
阈值且无文档化基准
