10+ QA Intern Interview Questions and Answers

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.

BlackBox Testing is a software testing method where the internal structure/design of the system being tested is not known to the tester.

• BlackBox Testing focuses on testing the functionality of the software without knowing its internal code.

• Testers only interact with the software through its user interface.

• Test cases are designed based on requirements and specifications.

• Examples: User acceptance testing, system testing.

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

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
