10+ QA Intern Interview Questions and Answers

Test cases for real-time products are generated by identifying key functionalities, creating scenarios, prioritizing test cases, and executing them.

• Identify key functionalities of the real-time product

• Create test scenarios based on different user interactions and system responses

• Prioritize test cases based on criticality and impact on the product

• Execute test cases to validate the functionality and performance of the real-time product

I have developed test cases for various projects including UI testing, API testing, regression testing, and performance testing.

• Developed test cases for UI testing by verifying the functionality of buttons, forms, and navigation.

• Created test cases for API testing by checking the response codes, data validation, and error handling.

• Designed test cases for regression testing to ensure new features do not break existing functionality.

• Implemented test cases for performance testing...read more

Software testing life cycle is a process of planning, designing, executing, and reporting on tests performed on software.

• Includes test planning, test design, test execution, and test closure

• Involves creating test cases, executing them, and reporting defects

• Ensures that software meets quality standards and requirements

• Examples: Waterfall model, Agile model, V-model

To test data in Excel file, use tools like Excel functions, data validation, and manual verification.

• Use Excel functions like VLOOKUP, SUM, COUNT, etc. to verify data accuracy.

• Apply data validation rules to ensure data consistency and integrity.

• Manually review the data for any anomalies or errors.

• Perform regression testing to check for any changes in data over time.

Selenium WebDriver is a popular automation tool used for testing web applications.

• Selenium WebDriver allows testers to automate web browser interactions.

• It supports multiple programming languages such as Java, Python, and C#.

• Selenium WebDriver can interact with different browsers like Chrome, Firefox, and Safari.

• It can handle dynamic web elements and perform actions like clicking buttons, entering text, and verifying text.

• Selenium WebDriver can be integrated with testing fram...read more

I will test the login page by verifying input validation, authentication process, error handling, and session management.

• Verify input validation by entering invalid credentials

• Test authentication process by entering correct credentials

• Check error handling by entering incorrect credentials

• Test session management by logging in and out multiple times

Bug Life Cycle is the process of a bug from identification to resolution in software testing.

• Bug is identified by tester

• Bug is reported in bug tracking system

• Bug is assigned to developer

• Developer fixes the bug

• Bug is retested by tester

• Bug is closed if fixed or reopened if not

The process is important because it ensures quality, efficiency, and consistency in the outcome.

• Ensures quality control by following specific steps and guidelines

• Improves efficiency by streamlining tasks and reducing errors

• Maintains consistency in the outcome by standardizing procedures

• Helps in identifying and resolving issues early in the development cycle

Defect clustering is the phenomenon where a small number of modules or functionalities in a software system are responsible for the majority of defects.

• Defect clustering suggests that a small portion of the software code is more error-prone than others.

• Identifying and focusing on these high-defect modules can help improve overall software quality.

• Examples of defect clustering include certain modules consistently causing issues or specific functionalities leading to frequent d...read more

Manual testing is the process of manually testing software for defects, functionality, and usability.

• Involves testers executing test cases manually without the use of automation tools

• Requires human intervention to observe and verify the expected outcomes

• Helps in identifying user interface issues, usability problems, and other defects

• Can be time-consuming and prone to human error

• Examples include exploratory testing, ad-hoc testing, and regression testing

Functional testing focuses on the specific behavior of a system, while non-functional testing evaluates the system's performance, reliability, and usability.

• Functional testing ensures that the software functions as expected based on the requirements.

• Non-functional testing evaluates aspects like performance, security, scalability, and usability.

• Examples of functional testing include unit testing, integration testing, and system testing.

• Examples of non-functional testing includ...read more

Lifecycle of a test involves planning, designing, executing, and analyzing results.

• Planning: Define test objectives, scope, and resources.

• Design: Create test cases and test data.

• Execution: Run tests and record results.

• Analysis: Review results, report defects, and improve testing process.

• Examples: Unit testing, integration testing, system testing, regression testing.

Vlookup is a function in Excel used to search for a value in a table and return a corresponding value from another column.

• Vlookup stands for 'vertical lookup'

• It searches for a value in the first column of a table and returns a value in the same row from a specified column

• Syntax: =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])

• Example: =VLOOKUP(A2, B2:D10, 3, FALSE) - searches for value in A2 in the range B2:D10 and returns the value in the 3rd column

• The last...read more
