readme: `# Imhotep React + Playwright Project
|

|
||||
This project was scaffolded with \`imhotep init --preset react\`.
|
||||
|
||||
## Getting Started
|
||||
|
||||
\`\`\`bash
|
||||
npm install
|
||||
npx playwright install
|
||||
npm test
|
||||
\`\`\`
|
||||
|
||||
## Project Structure
|
||||
|
||||
- \`imhotep.config.js\` - Imhotep configuration
|
||||
- \`tests/\` - Test files
|
||||
- \`fixtures/\` - HTML fixtures for spatial testing
|
||||
|
||||
## Writing Tests
|
||||
|
||||
Use the Imhotep DSL for spatial assertions:
|
||||
|
||||
\`\`\`typescript
|
||||
const ui = imhotep(page);
|
||||
await ui.expect('.header').to.be.above('.content', { minGap: 16 });
|
||||
\`\`\`
|
||||
`
|
||||
};
