Set Browser Size using Navigator

Navigator object has SetSize and SetPosition actions. At the beginning of your test open a browser at specific URL and then set window size and position. This method works both for Rapise native browser connectors and Selenium.

function TestInit()
{
    Navigator.Open("http://libraryinformationsystem.org/react-js");
    Navigator.SetSize(800, 600);
    Navigator.SetPosition(100, 50);
}

Set Browser Size using WebDriver

If you are testing using pure Selenium API you may use Window.SetSize and Window.SetPosition methods.

function TestInit()
{
    WebDriver.CreateDriver();
    WebDriver.SetUrl("http://libraryinformationsystem.org/react-js");
    WebDriver.Window().SetSize(800, 600);
    WebDriver.Window().SetPosition(100, 50);
}
