Fundamentals Flashcards

What is the main objective of software testing?

Answer: Identify defects and verify requirements

The primary goal of software testing is to identify defects and ensure that the software meets the specified requirements and performs as expected.

Which principle states that exhaustive testing is impossible?

Answer: Exhaustive testing is impossible

The principle of 'Testing is exhaustive' states that it is impossible to test every possible input, so risk-based and prioritized testing is essential.

What is the purpose of the 'Pesticide Paradox' principle in software testing?

Answer: Modify tests regularly to find new defects

The 'Pesticide Paradox' principle states that running the same tests repeatedly will not uncover new defects, so tests should be updated regularly.

Which type of testing is performed without executing the code?

Answer: Static testing

Static testing, such as code reviews and inspections, is conducted without executing the software, identifying defects early in development.

What is the key benefit of early testing?

Answer: Identify defects early to minimize costs

Early testing helps identify defects in the initial stages of development, reducing the cost and effort required to fix them later.

Which testing concept states that most defects are found in a few modules?

Answer: Defect clustering

The 'Defect Clustering' principle suggests that most defects tend to be concentrated in a small number of software modules.
