   A test automation team is integrating static analysis into their CI pipeline. They have a mix of unit tests, API tests, and UI tests. The team wants to enforce different coding standards for each type of test code. They also want to ensure that the static analysis runs quickly to avoid slowing down the pipeline. Which approach best meets these needs?

   • ARun static analysis only on the UI test code because it is the most complex
   • BRun static analysis on a schedule rather than on every commit to save time
   • CUse a single static analysis job with a generic ruleset for all test code
   • DConfigure separate static analysis jobs for each test type, each with its own ruleset, and run them in parallel

   A test automation team is experiencing frequent test failures due to test code that is difficult to maintain. They want to use static analysis to identify code that is hard to understand and modify. Which static analysis metric would be most useful for this purpose?

   • ACode coverage percentage
   • BCyclomatic complexity
   • CExecution time of tests
   • DNumber of test cases

   What is a common limitation of static analysis tools?

   • AThey require a running application to analyze the code
   • BThey are unable to detect syntax errors
   • CThey can only be used on compiled languages
   • DThey may report issues that are not actual defects (false positives)

   A test automation team is using a static analysis tool that flags a potential null pointer dereference in a test utility method. The team has reviewed the code and determined that the method is always called with a non-null argument in the current test suite. However, the method is public and could be used in future tests with a null argument. What is the most appropriate action?

   • AAdd a null check and throw an IllegalArgumentException with a clear message
   • BSuppress the warning with a comment explaining that the method is always called with non-null arguments
   • CChange the method to private to prevent external calls
   • DIgnore the warning because the tests currently pass

   A test automation team has a large, legacy test codebase with many existing violations of coding standards. They want to introduce static analysis into their CI pipeline without overwhelming the team with thousands of existing issues. They also want to ensure that new code does not introduce new violations. Which strategy best balances these constraints?

   • ARun static analysis once and fix all existing violations before enabling it in CI
   • BConfigure the static analysis tool to fail the build only on new violations, while reporting existing issues as warnings
   • CDisable static analysis for the legacy code and only run it on new test code
   • DRun static analysis only on a nightly basis and review the report manually
