How to set browser browser window size

Question

I am trying to create a cross browser Python-Seleniumscript tag . Therefore, I need all the results to be the same, whatever webdriver( Chromeor IE). I can set the browser window size as follows:

driver.set_window_size(1920, 1080)

But the following code will return different values ​​for Chromeand IE:

element = driver.find_element_by_xpath('some_xpath')
element.location

since the viewing area (where the web content is displayed) differ ( Chrome- 1910x998, IE- 1904x965), despite the same window size. To get these values, I used

driver.execute_script('return document.documentElement.clientHeight')
driver.execute_script('return document.documentElement.clientWidth')

so i tried

driver.execute_script('document.documentElement.clientHeight = "990px";')
driver.execute_script('document.documentElement.clientWeight = "1900px";')

but no luck

So the question is, how do I set the browser viewport size to selenium?

Answer 1

:

def set_viewport_size(driver, width, height):
    window_size = driver.execute_script("""
        return [window.outerWidth - window.innerWidth + arguments[0],
          window.outerHeight - window.innerHeight + arguments[1]];
        """, width, height)
    driver.set_window_size(*window_size)

:

from selenium import webdriver

driver = webdriver.Chrome()

# set the viewport size to 800 x 600
set_viewport_size(driver, 800, 600)

# display the viewport size
print driver.execute_script("return [window.innerWidth, window.innerHeight];")

Answer 2

:

driver.manage().window().setSize(new org.openqa.selenium.Dimension(1900, 990));

1900 - , 990 - .

Answer 3

Here is the Java version for @Florent B. Answer:

        int width = "500";
        int height = "500";

        //Remove the window from fullscreen (optional), if it s in fullscreen the outerHeight is not accurate
        browser.manage().window().setSize(new Dimension(800,800));

        JavascriptExecutor js= (JavascriptExecutor)browser;

        String windowSize = js.executeScript("return (window.outerWidth - window.innerWidth + "+width+") + ',' + (window.outerHeight - window.innerHeight + "+height+"); ").toString();

        //Get the values
        width = Integer.parseInt(windowSize.split(",")[0]);
        height = Integer.parseInt(windowSize.split(",")[1]);

        //Set the window
        browser.manage().window().setSize(new Dimension(width, height));
