TCS Senior Automation Tester Interview Questions, Process, and Tips

I am a Senior Automation Test Engineer with 5+ years of experience in designing and implementing automated testing frameworks.

• 5+ years of experience in automation testing

• Proficient in designing and implementing automated testing frameworks

• Strong knowledge of testing tools like Selenium, Appium, and JUnit

• Experience in creating test scripts and executing test cases

• Ability to analyze test results and identify defects

The syntax for using driver.findElement in Selenium is driver.findElement(By locator)

• Use driver.findElement(By locator) to locate a single element on the web page

• Specify the locator strategy (e.g. By.id, By.name, By.xpath) to identify the element

• Example: WebElement element = driver.findElement(By.id("username"));

Different types of assertions and syntax for hard assertion in TestNG

• Types of assertions: Hard assertions and Soft assertions

• Syntax for hard assertion in TestNG: Assert.assertEquals(expected, actual)

Types of wait mechanisms include implicit wait, explicit wait, fluent wait, and thread.sleep.

• Implicit wait: Waits for a certain amount of time before throwing a NoSuchElementException.

• Explicit wait: Waits for a certain condition to occur before proceeding further.

• Fluent wait: Waits for a condition to be true with a specified polling frequency.

• Thread.sleep: Pauses the execution for a specified amount of time.

Frames in Selenium can be managed using switchTo() method to navigate between frames.

• Use driver.switchTo().frame() method to switch to a frame by index, name or WebElement

• Use driver.switchTo().defaultContent() method to switch back to the main content

• Use driver.switchTo().parentFrame() method to switch to the parent frame

Use a Set data structure to remove duplicates from an array of strings.

• Create a Set from the array to automatically remove duplicates

• Convert the Set back to an array to get the unique values

List, Set, and Map are different types of collections in Java used to store and manipulate groups of objects.

• List is an ordered collection that allows duplicate elements. Example: ArrayList, LinkedList

• Set is a collection that does not allow duplicate elements. Example: HashSet, TreeSet

• Map is a collection of key-value pairs where each key is unique. Example: HashMap, TreeMap

I would analyze the user stories and application functionality to identify the root cause of the mismatch and work towards resolving it.

• Review the user stories and application functionality to understand the discrepancies

• Communicate with stakeholders to clarify requirements and expectations

• Update test cases and automation scripts to align with the corrected user stories

• Collaborate with developers to address any underly

I have over 5 years of experience in automation testing, with a focus on creating and executing test scripts for web applications.

• Developing automation test scripts using tools like Selenium and TestNG

• Creating test plans and test cases based on requirements

• Executing test cases and reporting defects

• Collaborating with developers and QA team to ensure quality of the product

• Participating in Agile ceremonies such as sprint

Demonstrating feature file step definitions with different sets of data in a previous project scenario

• Create a feature file with a scenario outline that includes placeholders for different sets of data

• Write step definitions that use the placeholders to run the scenario with different data sets

• Use data tables or examples in the feature file to provide the different sets of data

• Run the scenario with different data sets t...read more

To count URLs in an HTML page using Selenium and open the URL containing your name, you can use a combination of Selenium WebDriver methods and regular expressions.

• Use Selenium WebDriver to navigate to the HTML page and retrieve its source code

• Use regular expressions to identify and count the URLs in the source code

• Iterate through the list of URLs to find the one containing your name

• Use Selenium WebDriver to open the U

Use regular expressions to separate letters and digits from a string in Java.

• Use the String class's split() method with a regular expression to separate letters and digits.

• Create a regular expression pattern that matches either letters or digits.

• Store the separated letters and digits in separate arrays.

The output of the code will be 'animal is created' followed by 'Dog is created'.

• The code defines a class Animal with a constructor that prints 'animal is created'.

• It also defines a class Dog that extends Animal, with a constructor that prints 'Dog is created'.

• In the main method, an instance of Dog is created, which will trigger the constructors of both Animal and Dog classes.

The output will be 'HelloThere'

• Concatenation of 'Hello' and 'There' results in 'HelloThere'

• The final string is printed using System.out.println()

The code creates a StringBuffer object with 'Hello' and appends 'There' to it before printing the final string.

• StringBuffer is mutable, so the original 'Hello' string can be modified

• The append() method adds the specified string to the end of the buffer

• The final output will be 'HelloThere'

Option a is valid, option b is valid, option c is invalid.

• Option a is valid because ChromeDriver is a subclass of WebDriver, so it can be assigned to a WebDriver reference.

• Option b is valid because ChromeDriver is a subclass of WebDriver, so it can be instantiated using a WebDriver reference.

• Option c is invalid because WebDriver is an interface and cannot be instantiated directly. It can only be used as a reference typ

Sort input array of strings in descending order without using inbuilt functions

• Iterate through the array and compare each element with the rest to find the largest element

• Swap the largest element with the first element, then repeat the process for the remaining elements

• Continue this process until the array is sorted in descending order

findElement returns the first matching element on the page, while findElements returns a list of all matching elements.

• findElement returns a single WebElement matching the locator provided

• findElements returns a list of WebElements matching the locator provided

• findElement will throw NoSuchElementException if no element is found, while findElements will return an empty list

getwindowhandle returns the handle of the current window, getwindowhandles() returns handles of all open windows

• getwindowhandle returns a single window handle, while getwindowhandles() returns a set of window handles

• getwindowhandle is used to switch between windows in Selenium WebDriver

• Output type of getwindowhandle is String, while output type of getwindowhandles() is Set
