You can set default browser size by running:
var width = 800; var height = 600; browser.driver.manage().window().setSize(width, height);
To maximize the browser window run:
To set position run:
var x = 150; var y = 100; browser.driver.manage().window().setPosition(x, y);
If you get error:
WebDriverError: unknown error: operation is unsupported with remote debugging
Operation not supported when using remote debugging Some WebDriver commands (e.g. resizing the browser window) require a Chrome extension to be loaded into the browser. ChromeDriver normally loads this "automation extension" every time it launches a new Chrome session.
However ChromeDriver can be instructed to connect to an existing Chrome session instead of launching a new one. This is done using 'debuggerAddress' in the Capabilities (aka ChromeOptions) object. Since the automation extension is only loaded at startup, there are some commands that ChromeDriver does not support when working with existing sessions through remote debugging.
If you see the error "operation not supported when using remote debugging", try rewriting the test so that it launches a new Chrome session. This can be done by removing 'debuggerAddress' from the Capabilities object.
