What Is Automation Testing? (Simple Definition + Example) 

Automation testing is the process of using tools and scripts to automatically execute test cases, validate expected results, and generate reports without manual effort. 

In today’s Agile and DevOps-driven software development environment, automation testing plays a crucial role in ensuring software quality, reducing repetitive manual work, and accelerating release cycles. Organizations such as TCS increasingly rely on automation-first testing approaches to improve efficiency and support continuous delivery. 

Automation testing enables teams to execute large regression suites repeatedly with greater speed, accuracy, and consistency than manual testing. 

Simple Example (TCS Interview Style) 

One of the easiest ways to understand automation testing is by comparing it with manual testing. 

Manual Testing 

In manual testing, a tester performs every action manually. 

Typical steps include: 

These steps must be repeated every time the application is tested. 

Automation Testing 

In automation testing, the same workflow is executed automatically using scripts. 

Typical steps include: 

The script can be executed repeatedly without manual intervention, making it ideal for regression and repetitive testing scenarios. 

Why TCS Prefers Automation 

TCS has increasingly adopted Quality Engineering (QE) practices and automation-driven testing models because automation offers significant advantages over traditional manual testing. 

Faster Regression Cycles 

Automation significantly reduces the time required to execute regression test suites. 

Tasks that may take several days manually can often be completed within a few hours using automation. 

Reduced Testing Cost 

Although automation requires an initial investment in framework development and script creation, it helps reduce long-term testing costs by minimizing repetitive manual effort. 

Continuous Testing in Agile and DevOps 

Automation supports continuous testing throughout the software development lifecycle. 

This enables: 

Better Test Coverage 

Automation allows teams to execute: 

This results in higher application quality and reduced production defects.

   @FindBy(id=”password”) 
   WebElement password; 
 
   @FindBy(id=”loginBtn”) 
   WebElement loginBtn; 
 
   public void login(String user, String pass){ 
       username.sendKeys(user); 
       password.sendKeys(pass); 
       loginBtn.click(); 
   } 
} 

Explanation 

In this example: 

  • Login page elements are stored in one class.  
  • The login() method performs login actions.  
  • Test scripts can directly call the method without handling locators.  

9. What Are Selenium Locators? 

Locators help Selenium identify web elements on a page. 

Common Selenium Locators 

Locator Usage 
ID Fastest

Always prefer: 

  1. ID  
  1. Name  
  1. CSS Selector  
  1. XPath  

This generally improves execution speed and reliability. 

10. XPath Example 

Example 

//input[contains(@id,’user’)] 

Use Case 

Useful when element IDs are dynamic and partially predictable. 

11. CSS Selector Example 

Example 

input#username 

Advantages 

  • Faster than XPath in many scenarios  
  • Cleaner syntax  
  • Easier maintenance  

12. Types of Waits in Selenium

Explicit Wait 

  • Waits for a specific condition.  
  • More efficient and recommended.  

Fluent Wait 

  • Provides polling intervals.  
  • Ignores specified exceptions while waiting.  

13. Explicit Wait Example 

WebDriverWait wait = 
new WebDriverWait(driver, Duration.ofSeconds(10)); 
 
wait.until( 
ExpectedConditions.visibilityOf(element) 
); 

Why Use Explicit Wait? 

Explicit waits help: 

  • Reduce flaky tests

Data-driven testing allows the same test to run with multiple data sets. 

Common Sources 

  • TestNG @DataProvider  
  • Excel files  
  • JSON files  
  • Properties files  
  • Databases  

Benefits 

  • Reduced code duplication  
  • Better test coverage  
  • Easy maintenance  

Real-Time Scenario-Based TCS Automation Questions 

Scenario 1: Login Button Enabled Only After Valid Input 

Solution 

  • Verify the button is initially disabled.  
  • Enter valid credentials.  
  • Verify the button becomes enabled.  

Validation Points 

  • Disabled state before input  
  • Enabled state after input  
  • Successful login after click  

Scenario 2: Dynamic Element IDs 

Approach 

Use XPath functions such as: 

  • contains()  
  • starts-with()  

Example 

//input[contains(@id,’user’)] 

This helps locate elements even when IDs change dynamically. 

Scenario 3: Captcha on Login Page 

Correct TCS Interview Answer 

Captcha should not be automated. 

Instead: 

  • Disable captcha in the test environment.  
  • Use a bypass mechanism provided by developers.  
  • Focus automation on business functionality.  

Scenario 4: Handling iFrames 

Example 

driver.switchTo().frame(“frameName”); 

Steps 

  1. Switch to frame.  
  1. Perform actions.  
  1. Switch back to default content.  

driver.switchTo().defaultContent(); 

Scenario 5: File Upload 

Example 

upload.sendKeys(“C:\\resume.pdf”); 

Explanation 

Selenium directly interacts with the file input element and uploads the file without opening the system file dialog. 

Scenario 6: Flaky Tests in TCS Projects 

Common Fixes 

  • Remove unnecessary Thread.sleep()  
  • Use Explicit Waits  
  • Improve locator strategies  
  • Handle synchronization properly  

Interview Answer 

Flaky tests are unstable tests that pass sometimes and fail sometimes without code changes. The solution is proper synchronization and stable locators. 

Scenario 7: Cross-Browser Testing 

Common Approaches 

  • TestNG parameters  
  • Selenium Grid  

Benefits 

  • Browser compatibility validation  
  • Parallel execution  
  • Reduced execution time  

Scenario 8: Screenshot on Failure 

Example 

TakesScreenshot ts = 
(TakesScreenshot) driver; 

Purpose 

Screenshots help: 

  • Debug failures  
  • Improve reporting  
  • Provide evidence for defects  

Scenario 9: Parallel Execution 

Example 

<suite parallel=”tests” 
      thread-count=”3″> 

Benefits 

  • Faster execution  
  • Reduced regression cycle time  
  • Better resource utilization  

Scenario 10: Handling Multiple Windows 

Example 

driver.switchTo() 
     .window(windowHandle); 

Common Use Cases 

  • Payment gateways  
  • Social media login windows  
  • Pop-up windows  

Selenium Automation Code Examples (TCS Style) 

Java + Selenium + TestNG Example 

@Test 
public void loginTest(){ 
 
   driver.get(“https://example.com”); 
 
   loginPage.login( 
       “admin”, 
       “test123” 
   ); 
 
   Assert.assertTrue( 
       driver.getTitle() 
             .contains(“Dashboard”) 
   ); 
} 

What This Script Does 

  1. Opens the application.  
  1. Performs login.  
  1. Verifies dashboard page.  
  1. Marks the test as pass or fail.  

Python Selenium Example 

from selenium import webdriver 
 
driver = webdriver.Chrome() 
 
driver.get(“https://example.com”) 
 
driver.find_element( 
   “id”, 
   “username” 
).send_keys(“admin”) 

Explanation 

This script: 

  • Launches Chrome browser  
  • Opens the application  
  • Locates username field  
  • Enters test data  

Test Data Example Using JSON 

{ 
 “username”: “admin”, 
 “password”: “test123” 
} 

Why JSON? 

JSON is commonly used because: 

  • It is lightweight.  
  • It is easy to read.  
  • It supports structured test data.  

HTML Example for Locator Practice 

<input 
type=”text” 
id=”username” 
class=”input-field” /> 

Suitable Locators 

ID Locator 

driver.findElement(By.id(“username”)); 

CSS Selector 

driver.findElement( 
By.cssSelector(“#username”)); 

XPath 

driver.findElement( 
By.xpath(“//input[@id=’username’]”));
