Window management (maximize, size) in Selenium Java - Test Execution Trace

Test Overview

This test opens a browser window, maximizes it, and then verifies that the window size is larger than a predefined minimum size.

Test Code - JUnit with Selenium WebDriver

Selenium Java

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.Dimension;
import static org.junit.jupiter.api.Assertions.assertTrue;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;

public class WindowManagementTest {
    private WebDriver driver;

    @BeforeEach
    public void setUp() {
        driver = new ChromeDriver();
    }

    @Test
    public void testWindowMaximizeAndSize() {
        driver.get("https://example.com");
        driver.manage().window().maximize();
        Dimension size = driver.manage().window().getSize();
        int width = size.getWidth();
        int height = size.getHeight();
        assertTrue(width >= 1024, "Window width should be at least 1024 pixels");
        assertTrue(height >= 768, "Window height should be at least 768 pixels");
    }

    @AfterEach
    public void tearDown() {
        if (driver != null) {
            driver.quit();
        }
    }
}

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts and ChromeDriver is initialized	Browser is launched but no page loaded yet	-	PASS
2	Browser navigates to https://example.com	Browser displays the example.com homepage	-	PASS
3	Browser window is maximized using driver.manage().window().maximize()	Browser window is maximized to full screen	-	PASS
4	Retrieve current window size with driver.manage().window().getSize()	Window size object with width and height is obtained	-	PASS
5	Assert window width is at least 1024 pixels	Window width value is checked	assertTrue(width >= 1024)	PASS
6	Assert window height is at least 768 pixels	Window height value is checked	assertTrue(height >= 768)	PASS
7	Test ends and browser is closed with driver.quit()	Browser is closed and WebDriver session ends	-	PASS

Failure Scenario

Failing Condition: Window size after maximize is smaller than expected minimum (width < 1024 or height < 768)

Execution Trace Quiz - 3 Questions

What does the test verify after maximizing the browser window?

A That the window title contains 'example.com'

B That the page URL is correct

C That the window size is at least 1024x768 pixels

D That the browser is in fullscreen mode

Key Result

Always verify window size after maximizing to ensure your tests run in the expected viewport, as maximize behavior can vary by OS and browser.
