Fields
| Field | Type | Description | Default |
|---|---|---|---|
| browser | string | Required. Browser engine to open. The session opens on the context’s automation server with a blank page and registers as a surface; use a goTo step (with surface) to navigate it. No cross-engine fallback — the one exception is edge, which is Chromium and opens on the same Chrome/chromedriver stack (it registers under the chrome engine, and defaults its surface name to chrome when you don’t set one).Accepted values: chrome, firefox, safari, webkit, edge | — |
| name | string | Optional. Surface-registry name later steps use in surface. Default: the engine name. Must be unique across all open surfaces — the context’s default browser already owns its engine name, so name a second same-engine session explicitly. An engine keyword may only name a session of that engine.Minimum length: 1. Pattern: \S | — |
| headless | boolean | Optional. Run this session headless. Default: the context’s browser headless setting. | — |
| size | object(Browser window size) | Optional. Outer window dimensions for this session. Default: the context’s browser window size. | — |
| viewport | object(Browser viewport size) | Optional. Viewport (page-content) dimensions for this session; the window is resized so the content area matches. Takes precedence over size when both are set. | — |
| driverOptions | object | Optional. Escape-hatch passthrough: merged into the session’s capabilities after the ones Doc Detective computes. Driver- and version-specific; use sparingly. | — |
