Question

Stochastic testing using statistical information or operational profiles uses the following method

A. Heuristic testing approach
B. Methodical testing approach
C. Model-based testing approach
D. Process or standard compliant testing approach

Answer 1

Stochastic testing uses operational profiles and statistics, which categorizes it under the model-based testing approach. This approach simulates real conditions based on statistical models to validate system behavior.

Step-by-step explanation:

Stochastic testing employs statistical information or operational profiles to decide whether a system behaves correctly under various conditions. This type of testing falls under the category of a model-based testing approach (C). Model-based testing uses statistical models to simulate real-world use, assuming that the operational profiles are correctly estimated from existing usage data. It's different from heuristic, methodical, or process/standard compliant approaches because it focuses on using probabilities and statistical methods to validate the behavior of the system under test.

In the context of hypothesis testing, a traditional approach includes setting up a null model and then evaluating whether the data conform to this model. This is an integral part of the scientific method, which guides researchers to separate pattern from noise in data, aligning closely with the principles behind stochastic testing that uses model-based approaches.
