FC0-U71 Software Development Concepts Practice Question
A software tester writes tests to verify that individual functions in a module return correct results when given specific inputs. These tests are isolated from other parts of the system. Which type of testing is being performed?
⚠ Common exam trap
Many exam-takers confuse 'testing individual functions' with 'integration testing' because they overlook the key phrase 'isolated from other parts of the system,' which is the hallmark of unit testing, not integration testing.

Correct answer & explanation
✓
Unit testing
Unit testing is the correct answer because it involves testing individual functions or methods in isolation to verify they return correct outputs for specific inputs. This aligns directly with the scenario where the tester is focusing on single modules without dependencies on other system parts, which is the core definition of unit testing in software development.
