A team is testing a system with a model that has 200 transitions. They have a tool that can generate test cases for any coverage criterion. The team has a budget that allows for 80 test cases. They need to achieve the highest possible transition coverage within this budget. Which approach should they take?

Use the tool to generate test cases that maximize transition coverage within the 80-test limit.

Generate test cases for 100% transition coverage, then reduce the set to 80 by removing redundant tests.

Manually select 80 test cases that cover the most important transitions.

Generate test cases for state coverage, which requires fewer tests, and assume it is sufficient.

In model-based testing, what does 'state coverage' measure?

The percentage of requirements that are traceable to tests

The percentage of test cases that pass

The percentage of states in the model that have been visited

The percentage of transitions that have been exercised

Which of the following is an example of a test case selection criterion in model-based testing?

The color scheme used in the modeling tool

The level of model coverage to be achieved

The number of testers available in the team

The programming language used to implement the system

A test team uses a model-based testing tool that can automatically generate test cases from a state model. The tool supports various coverage criteria, including state, transition, and path coverage. The team needs to achieve a specific level of transition coverage (e.g., 90%) to meet regulatory requirements. How should they use the tool to achieve this?

Configure the tool to generate test cases until 90% transition coverage is achieved, using its coverage measurement feature.

Generate test cases using state coverage and assume it is equivalent to transition coverage.

Generate test cases using the tool's transition coverage criterion and then manually add test cases to reach 90%.

Use the tool to generate all possible paths and then select every tenth test case.
