What is exhaustive testing___________________?
Show answer Hide answer
Answer: C. impractical but possible
Explanation
Exhaustive testing is practically impossible because modern software systems contain an infinite number of input combinations. Testing every single execution path requires more computational resources and time than any project can provide. Although every test scenario can be conceptualized, executing them all in a real-world environment remains unfeasible. Software testing principles state that complete testing is unattainable for all except the most trivial programs. Combinatorial explosion occurs when input parameters multiply, creating billions of potential states to evaluate. Quality assurance professionals rely on risk-based sampling techniques instead of attempting impossible exhaustive verification.
Claiming exhaustive testing is always possible ignores the fundamental mathematical reality of combinatorial input explosion. Stating that it is practically possible contradicts decades of empirical software engineering research and testing limitations. Describing it as impossible without acknowledging its theoretical possibility misses the distinction between concept and execution.
