10+ Quality Assurance Tester Interview Questions and Answers

Test cases are scenarios designed to validate the functionality of a software application. Bug life cycle refers to the stages a bug goes through from identification to resolution.

• Test Cases: - Verify login functionality with valid credentials - Test adding items to a shopping cart - Validate search functionality by entering keywords

• Bug Life Cycle: - Bug identification - Bug logging - Bug prioritization - Bug fixing - Bug retesting - Bug closure

• Example: A tester discovers a b...read more

I have 3 years of experience in testing. Testing is the process of evaluating a system or application to identify defects or errors.

• I have 3 years of experience in manual and automated testing

• Testing involves executing test cases to identify defects or errors in a system or application

• Types of testing include functional testing, regression testing, performance testing, and user acceptance testing

Black box, White Box, Regression, and Smoke testing are different types of software testing techniques.

• Black box testing focuses on testing the functionality of the software without knowing its internal code.

• White box testing involves testing the internal code structure, paths, and logic of the software.

• Regression testing is performed to ensure that new code changes do not adversely affect existing functionalities.

• Smoke testing is a preliminary testing to check if the softwar...read more

I am comfortable with coding and my preferred language is Java.

• Comfortable writing test scripts and automation code

• Familiar with debugging and troubleshooting code issues

Yes, I can write code for File Handling in various programming languages.

• Use functions like fopen(), fclose(), fread(), fwrite() for file operations

• Handle errors using error handling techniques like try-catch or if-else statements

• Examples: C - fopen("file.txt", "r"), Python - with open("file.txt", "r") as file:

Java methods are used to perform specific tasks and create objects.

• Methods are defined within a class and can be called to perform a specific action.

• To create an object, use the 'new' keyword followed by the class name and constructor.

• Methods can have parameters and return values, allowing for flexibility and reusability.

• Example: public void printMessage(String message) { System.out.println(message); }

• Example: MyClass obj = new MyClass();

Sanity testing is a quick and focused testing to ensure that the most critical functionalities of a software application are working correctly after changes.

• Sanity testing is a subset of regression testing.

• It is usually performed after a minor change in the code or functionality.

• The main goal of sanity testing is to verify that the new code changes have not adversely affected the existing functionalities.

• It is not exhaustive and does not cover all possible test scenarios.

• Exam...read more

Smoke testing is a preliminary testing to check if the basic functionalities of a software application are working fine.

• Performed at the beginning of the testing process

• Focuses on testing the critical functionalities

• Not exhaustive testing, just a quick check to see if the application can be further tested

• Helps in identifying major issues early in the development cycle

Selenium and Cypress are both popular automation testing tools, but they have some key differences.

• Selenium is a widely used open-source tool for automating web browsers, while Cypress is a newer tool that focuses on modern web development practices.

• Selenium supports multiple programming languages like Java, Python, and C#, whereas Cypress uses JavaScript.

• Cypress provides built-in features like time travel and automatic waiting, making it easier to write and debug tests.

• Selen...read more
