Unit Recap: Browser Interactions

A comprehensive review of browser-level control, context switching, and advanced interactions.

Concept

In this unit, we moved beyond simple element interaction to controlling the browser itself. You learned how to navigate history, switch contexts (windows, frames, alerts), manage cookies, and use advanced tools like the Virtual Authenticator.

Navigation & Control

Navigation: back(), forward(), refresh().
Window: setSize(), maximize() for responsive testing.
Cookies: addCookie(), deleteCookie() for session management.

Context Switching

Alerts: switchTo().alert() to accept/dismiss popups.
Frames: switchTo().frame() to reach embedded content.
Windows: switchTo().window() to handle tabs/popups.

Visual Evidence

Screenshots: getScreenshotAs() for failure logs.
PDF: print() for full-page reports.

Advanced Tools

JS Executor: executeScript() for tricky interactions.
Virtual Auth: Simulate WebAuthn/FIDO2 keys.

// 1. Manage Window & Cookies
driver.manage().window().maximize();
driver.manage().addCookie(new Cookie("session", "123"));

// 2. Navigate & Switch Contexts
driver.get("https://example.com");
driver.switchTo().frame("content-frame");
driver.findElement(By.id("btn")).click();
driver.switchTo().defaultContent();

// 3. Handle Alert
driver.switchTo().alert().accept();

// 4. Capture Evidence
File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

driver.quit();

Code Breakdown

driver.manage().window().maximize(): Ensures a consistent full-screen viewport for testing.
driver.switchTo().defaultContent(): Crucial step to return to the main page after working inside a frame.
driver.switchTo().alert().accept(): Handles a native JavaScript popup that blocks the page.

Pro Tip

Context Awareness

Always know "where" Selenium is focused. If an element isn't found, check if you need to switch to a frame, window, or alert.

Clean Up

Use driver.quit() to close all windows and clear the session. Use removeVirtualAuthenticator() to detach keys.

Stability First

Prefer native WebDriver commands over JS. Use JS only when necessary (e.g., scrolling stubborn elements).
