   A team is developing a non-safety-related internal tool for managing employee records. The tool has a module for calculating vacation days. The module has complex rules based on years of service and employment type. The team has a limited testing budget. What is the most appropriate white-box testing approach?

   • ASkip white-box testing and use only black-box testing to save time.
   • BAchieve 100% statement coverage across the entire tool.
   • CFocus on achieving high branch coverage in the vacation calculation module.
   • DUse a static analysis tool to find potential issues without executing the code.

   A test team is using a coverage tool that reports both statement and branch coverage. For a particular module, the tool reports 100% statement coverage and 80% branch coverage. What does this indicate?

   • ASome branches in the module have not been tested.
   • BThe module is fully tested and ready for release.
   • CThe tool is not working correctly because statement coverage cannot be higher than branch coverage.
   • DThe module has no faults.

   A retail company is developing a customer loyalty points calculation module. The module is not safety-related, but a bug in the calculation would cause incorrect discounts and customer complaints. The team has limited time and budget. Which approach best balances thoroughness with the non-safety-related context?

   • AApply 100% path coverage to the module, testing every possible route through the code.
   • BApply 100% condition coverage, ensuring each Boolean sub-expression is evaluated to both true and false.
   • CApply 100% branch coverage to the module, ensuring both true and false outcomes of each decision are tested.
   • DApply 100% statement coverage to the module, focusing on exercising all executable lines of code.
