Ow can I ensure Windows maximization in selenium?

50    Asked by Dadhijaraj in QA Testing , Asked on Jun 12, 2024

I am currently engaged in a particular task that is related to automating a web-based application test by using selenium. While going through the testing process, I encountered an issue where certain elements on the page are not visible or even clickable because they are lying outside the current view of the browser window. Thus this issue is causing my test to fall quickly. How can I troubleshoot and resolve this particular issue by using the technique of maximizing the browser window at the beginning of every test?

In the context of selenium, you can easily ensure that the browser window is maximized at the beginning of each testing scenario by using the method called “maximize_window” which is provided by selenium. This method would help you in resizing the browser window to its maximum possible size and width which would ensure you that all the elements should be visible and even clickable on the viewport. This would help in reducing issues related to the element being out of view due to the insufficient size of the browser window. Here are the steps given:-

First, you would need to install the WebDriver Instances.

Now you should navigate to the target web-based application.

Now you can approach maximizing the browser window by using the method of “maximize_windows”.

Proceed with the rest of the test scenario.

Now you can close the browser once the test is completed.

Here is the example of implementation given in the context of Python programming language:-

From selenium import webdriver

# Initialize the WebDriver (e.g., using Chrome)
Driver = webdriver.Chrome(executable_path=’path/to/chromedriver’)
# Navigate to the web application
Driver.get(‘https://example.com’)
# Maximize the browser window
Driver.maximize_window()
# Proceed with other test steps
# Example: Interact with elements on the page
Element = driver.find_element_by_id(‘some-element-id’)
Element.click()
# Add other test actions as needed
# Close the browser after the test is complete
Driver.quit()
Here is the example given in Java programming language:-

Import org.openqa.selenium.By;
Import org.openqa.selenium.WebDriver;
Import org.openqa.selenium.WebElement;
Import org.openqa.selenium.chrome.ChromeDriver;
Public class MaximizeWindowTest {
    Public static void main(String[] args) {
        // Set the path to the ChromeDriver executable
        System.setProperty(“webdriver.chrome.driver”, “path/to/chromedriver”);
        // Initialize the WebDriver (using Chrome)
        WebDriver driver = new ChromeDriver();
        // Navigate to the web application
        Driver.get(https://example.com);
        // Maximize the browser window
        Driver.manage().window().maximize();
        // Proceed with other test steps
        // Example: Interact with elements on the page
        WebElement element = driver.findElement(By.id(“some-element-id”));
        Element.click();
        // Add other test actions as needed
        // Close the browser after the test is complete
        Driver.quit();
    }
}
