Switch between browser windows and tabs
Modern user journeys often open new browser windows or tabs. Payment gateways, identity providers, documentation links, and third-party services frequently launch in a separate window.
The Switch window step allows you to change the active browser context so your test can interact with the correct tab or window.
Without switching window, your test remains focused on the original tab, even if the user has been redirected elsewhere.
Why switching window is essential
When a new window opens:
The browser creates a separate context
The URL may change to a different domain
The title may differ from the originating page
Your test must explicitly move focus to that window before interacting with elements inside it.
Switch window makes this transition controlled and predictable.
How window selection works
You can switch the active browser window based on:
Domain
Page title
This allows you to reliably target the correct window, even when multiple tabs are open.
For example:
Switch to a payment provider by matching its domain
Switch to a confirmation page by matching its title
Move back to your original application after completing an external flow
Common real-world scenarios
Payment flows
Many checkout systems open card authorization or identity verification in a new tab. Switching window lets you:
Enter credentials
Approve transactions
Complete 3D Secure steps
Return to your application
External authentication
SSO providers and OAuth flows often redirect to another window. You can switch, complete the login, then return to verify the session.
Multi-tab workflows
Some user journeys intentionally open documentation, reports, or confirmation screens in new tabs. Switching window allows you to validate these interactions fully.
Reliable multi-context automation
Managing multiple browser windows is a common source of instability in traditional automation frameworks. By explicitly controlling the active window, your tests become:
Clearer
More maintainable
Less fragile
Switch window ensures your automation follows the same path your users do, even when that path spans multiple tabs or domains.
