A team is testing a model for an online payment system. The model has a decision point that checks `amount > 0 AND currency == 'USD'`. The team has a limited budget and wants to combine criteria to achieve a balanced suite. They are considering combining boundary value analysis (BVA) on the `amount` field with risk-based selection. The `amount` field has a valid range of 1 to 10,000. The team has identified that the 'currency conversion' feature is high-risk. Which combined approach is most effective?

Use path coverage to test all possible paths through the model

Apply BVA to the `amount` field and prioritize tests that exercise the high-risk 'currency conversion' feature

Apply only risk-based selection and ignore data boundaries

Apply only BVA to the `amount` field and ignore risk factors

Why is it necessary to define test selection criteria before generating test cases from a model?

Because selection criteria are required to validate that the model is syntactically correct

Because selection criteria determine the model's level of abstraction and notation

Because without criteria, the number of possible test cases may be too large to execute within time and budget constraints

Because the model itself cannot be executed without predefined selection criteria

A team has a model that can generate 10,000 unique test cases. Running all of them would take three weeks. The team has only three days for testing. They decide to use test selection criteria to reduce the suite. What is the primary purpose of applying test selection criteria in this situation?

To eliminate the need for any test execution

To replace the model with a simpler one

To increase the number of test cases to improve coverage

To manage the test suite size and focus testing effort on the most important test cases

A team is testing a banking application model. They have a limited regression test budget and must prioritize test cases. The team has identified that the 'fund transfer' feature has a high likelihood of failure due to recent code changes and a very high impact if it fails (financial loss). The 'view transaction history' feature has a low likelihood of failure and low impact. Which approach should the team use to select test cases?

Risk-based selection, prioritizing tests for 'fund transfer' over 'view transaction history'

Statement coverage, ensuring all statements in both features are tested equally

Equivalence partitioning, focusing on input classes for both features

Random selection, giving each test case an equal chance of being chosen
