Introduction

The minimize_window() method in Selenium WebDriver is used to minimize the browser window, sending it to the taskbar (Windows) or the dock (macOS), just like clicking the Minimize button on the browser window.

Unlike maximize_window(), which expands the browser to occupy the full screen, minimize_window() hides the browser from the desktop while keeping the WebDriver session active. This allows automation scripts to continue executing even though the browser window is minimized.

The minimize_window() method is useful for testing browser behavior after minimizing the window, verifying that the WebDriver session remains active, and simulating real user interactions.

In this tutorial, you will learn what the minimize_window() method is, why it is used, its syntax, practical examples, real-world applications, common mistakes, best practices, and frequently asked interview questions.

What is minimize_window()?

The minimize_window() method is a Selenium WebDriver command that minimizes the browser window.

It performs the same action as clicking the browser’s Minimize button.

Unlike closing the browser, minimizing only hides the browser window while the WebDriver session continues to run.

Why Do We Use minimize_window()?

The minimize_window() method is commonly used to:

Minimize the browser during automation.
Verify that the WebDriver session remains active.
Simulate real user behavior.
Test browser state changes.
Continue automation while the browser is minimized.
Validate application stability after minimizing the browser.

Syntax

driver.minimize_window()

The minimize_window() method does not accept any parameters.

Practical Example

The following example demonstrates how to minimize the browser window using Selenium WebDriver.

The automation script opens the Selenium practice website, minimizes the browser window, verifies that the page title is still accessible, and confirms that the WebDriver session remains active.

from selenium import webdriver


# Topic: 7. Browser Window Management - Minimize Window
# Practice site: https://the-internet.herokuapp.com/
#
# minimize_window() shrinks the browser window to the taskbar.


def test_minimize_window():
    driver = webdriver.Chrome()

    try:
        driver.get("https://the-internet.herokuapp.com/")

        driver.minimize_window()

        assert driver.title == "The Internet"

    finally:
        driver.quit()

Output

Browser launched successfully.

Website opened successfully.

Browser window minimized.

Page title verified successfully.

Assertion Passed.

Test Executed Successfully.

Understanding the Code

Import WebDriver

from selenium import webdriver

Imports the Selenium WebDriver module.

Launch Chrome Browser

driver = webdriver.Chrome()

Starts a new Chrome browser session.

Open the Website

driver.get("https://the-internet.herokuapp.com/")

Navigates to the Selenium practice website.

Minimize the Browser Window

driver.minimize_window()

Minimizes the browser window to the taskbar while keeping the WebDriver session active.

Verify the Page Title

assert driver.title == "The Internet"

Confirms that Selenium can still interact with the browser even though it is minimized.

Close the Browser

driver.quit()

Ends the WebDriver session and closes all browser windows.

Automation Testing Example

Suppose you’re testing a long-running automation suite that executes hundreds of test cases.

Instead of keeping the browser visible throughout the execution, you can minimize it while allowing the automation to continue.

driver.minimize_window()

This keeps the browser out of the way while maintaining the active WebDriver session.

Real-World Example

Consider an online banking application where a user minimizes the browser to check another application before returning to continue the transaction.

An automation script can minimize the browser and then verify that the session is still active and the application remains accessible.

Common Mistakes Beginners Make

Confusing minimize_window() with quit()

Incorrect

Some beginners think minimizing the browser closes the session.

It does not.

The browser remains open and the WebDriver session continues running.

Assuming Automation Stops After Minimizing

The browser is hidden, but Selenium continues executing all commands normally.

Using minimize_window() on Older Browser Versions

Some older browser versions or drivers may not fully support this method.

Always use the latest Selenium version and browser drivers.

Best Practices

Use minimize_window() only when minimizing the browser is part of the test scenario.
Verify that the WebDriver session remains active after minimizing.
Use assertions to confirm the application is still accessible.
Keep Selenium and browser drivers updated for full compatibility.
Always end the test with driver.quit().

Conclusion

The minimize_window() method is a Selenium browser window management command that minimizes the browser window while keeping the automation session active.

It is useful for testing browser state changes, simulating user behavior, and confirming that Selenium continues interacting with the browser even when it is minimized.

Although not used as frequently as maximize_window(), it is an important method to understand when working with browser window management.

Frequently Asked Questions (FAQs)

What does `minimize_window()` do?

It minimizes the browser window to the taskbar or dock while keeping the WebDriver session active.

Does `minimize_window()` close the browser?

No.

It only minimizes the browser window. The WebDriver session continues running.

Does `minimize_window()` accept any parameters?

No.

The syntax is:

driver.minimize_window()

Can Selenium still interact with a minimized browser?

Yes.

The browser is minimized, but Selenium can continue executing commands as long as the session is active.

When should I use `minimize_window()`?

Use it when your test scenario requires minimizing the browser or when you want to keep the browser out of the way during long-running automation.
