10+ TCS Interview Questions and Answers
Q1. What is a different test Level?
Different test levels are stages of testing that are performed to ensure software quality.
Unit testing - testing individual units or components of the software
Integration testing - testing how different units or components work together
System testing - testing the entire system as a whole
Acceptance testing - testing to ensure the software meets the requirements and is ready for release
Regression testing - testing to ensure that changes or updates to the software do not break ...read more
Q2. What is difference between regression and integration
Regression testing is testing the unchanged parts of the software after changes are made, while integration testing is testing the interaction between different components/modules.
Regression testing focuses on ensuring that previously developed and tested software still performs correctly after changes are made.
Integration testing focuses on testing the interaction between different components/modules to ensure they work together as expected.
Regression testing is typically do...read more
Q3. what is Exploratory Testing?
Exploratory testing is a dynamic and simultaneous approach to testing where testers design and execute tests on-the-fly.
It involves simultaneous learning, test design, and test execution.
Testers use their domain knowledge and experience to explore the software and identify defects.
It is an unscripted and ad-hoc testing technique.
Exploratory testing is useful when requirements are unclear or changing rapidly.
It helps uncover defects that might not be found through scripted tes...read more
Q4. What is "use case Testing"?
Use case testing is a technique to validate the system's behavior against its intended use.
Use case testing involves identifying and testing all possible scenarios that a user may encounter while using the system.
It helps to ensure that the system meets the user's requirements and expectations.
Use cases are created based on user stories and are used to define the system's behavior.
Test cases are then designed to validate each use case.
Example: Testing an e-commerce website's ...read more
Q5. Different method to sendkeys in selenium?
Different methods to send keys in Selenium include sendKeys(), clear() and sendKeys(CharSequence... keys)
sendKeys() method is used to enter text into an input field
clear() method is used to clear the existing text in an input field
sendKeys(CharSequence... keys) method is used to send a sequence of keys to an element
Q6. what is role and responsibilitir
The role of a Software Tester is to ensure that software applications are functioning correctly and meeting quality standards.
Testing software applications to identify bugs and defects
Creating test cases and test plans
Collaborating with developers to resolve issues
Reporting and documenting test results
Participating in quality assurance processes
Q7. Take one application and write test case
Test case for login functionality in a banking application
Verify that valid credentials allow user to login successfully
Verify that invalid credentials display an error message
Verify that password is case-sensitive
Verify that user is redirected to the correct page after login
Q8. What is automation testing
Automation testing is the use of software tools to control the execution of tests and compare actual outcomes with expected outcomes.
Automation testing helps in reducing human errors and increasing test coverage.
It is faster and more reliable compared to manual testing.
Examples of automation testing tools include Selenium, Appium, and JUnit.
Q9. what is encapsulatio
Encapsulation is the concept of bundling data and methods that operate on the data into a single unit, known as a class.
Encapsulation helps in hiding the internal state of an object and only exposing the necessary functionalities.
It allows for better control over the data by preventing direct access from outside the class.
Encapsulation promotes code reusability and modularity.
Example: In a class representing a car, the variables like speed and fuel level can be encapsulated a...read more
Q10. What is polymorphism
Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
It enables a single interface to be used for different data types or classes.
Examples include method overloading and method overriding in object-oriented programming.
Q11. Automation Framework with BDD
Automation framework with BDD focuses on behavior-driven development for automated testing.
BDD helps in creating test cases based on user behavior
Uses natural language to define test scenarios
Promotes collaboration between developers, testers, and business stakeholders
Tools like Cucumber, SpecFlow, and JBehave are commonly used for BDD automation
Q12. Different type of Testing
Different types of testing include functional testing, non-functional testing, manual testing, automated testing, regression testing, and performance testing.
Functional testing focuses on testing the functionality of the software.
Non-functional testing focuses on aspects like performance, usability, and security.
Manual testing involves testers manually executing test cases.
Automated testing involves using tools to automate test case execution.
Regression testing ensures that n...read more
