Multiple Browser Instances in Single Script

In a scenario like chatting, a test case may require 2 application users to be simultaneously logged in. Sahi Pro V5.1 and above provides the ability to launch new browser instances from a single script. These instances do not share cookies so they can allow multiple application users to be logged into the system simultaneously.

Details

Launches a new browser instance. Note that this browser instance does not share cookies with the base browser. This new browser instance is useful for testing functionality like chat where 2 simultaneous users need to be logged in into the system.

Once launched, steps can be directed to different browser instances by adding _selectBrowser API.

infoSahi tries to get a browser instance from a separate pool of instances (defined by browserType capacity in browser_types.xml). If one is available it will return immediately. If not, Sahi will wait and retry x number of times.
x is defined by property browser.max_wait_count_for_available_thread_from_dashboard in sahi.properties If an instance is still not available, _launchNewBrowser will fail.
