   A test team is using a coverage tool on a non-safety-related system. The tool reports that a particular function has 50% branch coverage. The team has already written test cases based on the requirements. What should they do next?

   • AAnalyze the untested branches and add test cases to exercise them.
   • BRemove the test cases that are not contributing to branch coverage.
   • CSwitch to a different coverage criterion, such as statement coverage, which will be higher.
   • DAccept the 50% branch coverage because the system is not safety-related.

   A team is using a coverage tool on a non-safety-related system. The tool instruments the code, which slows down the application. The team is concerned about the performance impact during testing. What is the best way to handle this?

   • AIncrease the timeout for all tests to accommodate the slower execution.
   • BUse the coverage tool only on the modules that are high-risk or have complex logic.
   • CDisable the coverage tool and rely on code reviews to find faults.
   • DRun the coverage tool only during the final regression test to get an overall picture.

   • AA static analysis tool that finds coding standard violations.
   • BA performance testing tool that simulates many users.
   • CA coverage measurement tool that instruments the code and reports statement and branch coverage.
   • DA test management tool that tracks test cases and results.

   A developer is writing unit tests for a non-safety-related utility class. The class has a method with a complex condition: `if (a > 0 && b < 10 || c == 5)`. The team wants to achieve high branch coverage. How many test cases are needed to cover all branches of this decision?

   • ASix test cases are needed to cover all possible combinations.
   • BOne test case is enough if the condition is true.
   • CFour test cases are needed to cover all combinations of the three conditions.
   • DTwo test cases are enough: one where the condition is true and one where it is false.
