TestiNG Integration

TestNG Annotations

Learning Outcome

5

Use TestNG annotations to structure test execution

4

Navigate between frames and nested frames

3

Handle alerts, prompts, and popups correctly

2

Switch between browser windows and tabs

1

Understand context switching in Selenium automation

Imagine you are shopping in a big mall 

You enter the main entrance of the mall

Recall

Suddenly a sales announcement pops up asking if you want a discount coupon

You then go to a different store inside the mall to buy clothes

After finishing the payment, you return to the main shopping area to continue shopping

While paying, the payment counter opens in another section of the store

Transition from Analogy to Technical Concept(Slide 5)

Moving between different stores in the mall

Switching between browser windows or tabs

Browser alert or popup

Sales announcement popup

Switching into a frame

Entering a section inside a store

Structure Your Testswith TestNG

Before each test

Test execution

After each test

Once per class

Once per class

@BeforeMethod

@AfterClass

@BeforeClass 

@AfterMethod

@Test

Setup test data

Core test logic

Cleanup resources

Initialize shared resources

Release shared resources

Switch Between Windows and Tabs

Get All Windows

Set handles = driver.getWindowHandles();

1

Loop Through Handles

for(String handle : handles) { driver.switchTo().window(handle); }

2

Switch To SpecificWindow

driver.switchTo().window(windowHandle);

3

Remember ParentWindow

String parentWindow = driver.getWindowHandle();

4

Handle OS-Level Popups via Workarounds

Code Example

Use SendKeys

For file inputs, bypass the dialog

Cannot Control OS Popups

Selenium can 't interact with system dialogs

driver.findElement(By.id ("upload")).sendKeys("C: \\file.txt");

Example: Payment Page Opens in NewTab

driver.switchTo().window(parent);

Return to Parent

String parent = driver.getWindowHandle();

Store Parent Handle

Complete payment form fields

Perform Payment

Find new handle in window handles collection

Switch to New Tab

Master Context Switching for Better Automation

  • ​Accept/dismiss alerts
  • Switch by index/name/element
  • Track multiple windows

  • Handle popup windows

  • Switch between tabs

Window Management

  • Return to default content
  • Navigate nested frames
  • Enter data in prompts
  • Extract alert text

Frame Navigation

Alert Handling

1

Use SendKeys for file uploads to bypass system dialogs

OS-level popups cannot be controlled directly by Selenium

Selenium uses window handles to switch between tabs/windows

TestNG provides annotations to organize test setup and cleanup

Context switching enables Selenium to interact with different browser elements
