Software Testing Software Testing Methodologies & Techniques

Question 1

Which testing technique involves testing without knowledge of the internal code structure?

Accepted Answer

Black-box testing

Answer

Black-box testing treats the software as an opaque system, focusing only on inputs and expected outputs without knowledge of internal logic.

Question 2

What is equivalence partitioning in software testing?

Accepted Answer

Grouping inputs that should behave the same way

Answer

Equivalence partitioning divides input data into groups (partitions) where all values in a partition are expected to be processed identically.

Question 3

Which testing approach tests individual units of code in isolation?

Accepted Answer

Unit testing

Answer

Unit testing verifies the smallest testable parts of an application independently from other components.

Question 4

What does boundary value analysis focus on?

Accepted Answer

Testing values at the edges of input ranges

Answer

Boundary value analysis targets values at the exact boundaries of input ranges, where defects are most likely to occur.

Question 5

Which type of testing verifies that new changes have not broken existing functionality?

Accepted Answer

Regression testing

Answer

Regression testing re-executes previously passing tests to confirm that code changes have not introduced new defects.
