ITPEC FE Morning April 2018 — Question 18 of 80
Static vs Dynamic Test Tools — static analysis examines source code without execution.
A static test tool analyzes the source code to detect errors without running the program (e.g., linters, code review tools, static analyzers).
A dynamic test tool requires program execution to perform its function.
Why (b) is correct:
- Detecting errors by analyzing source code = static analysis (no execution needed)
Why not others:
- (a) Calculating coverage from executed paths — requires running the program → dynamic
- (c) Generating a driver or stub — used for unit testing with execution → dynamic
- (d) Generating test data for a specific path — requires execution context → dynamic
Key rule: Static = no execution (code review, linting, formal verification). Dynamic = execution required (testing, coverage, profiling).
