   A test analyst is using a checklist to guide exploratory testing of a login form. The checklist includes items such as 'test with valid credentials', 'test with invalid credentials', 'test with empty fields', and 'test with special characters in the password'. Which of the following best describes the purpose of this checklist?

   • ATo replace the need for any other testing techniques.
   • BTo generate random inputs for the login form.
   • CTo ensure that common risks and important areas are covered during exploratory testing.
   • DTo define the exact expected output for each test case.

   A team is testing a financial calculation module that computes compound interest. The expected results are difficult to verify independently, but the team knows that if the principal is doubled, the final amount should also double (assuming the same rate and time). Which testing approach best leverages this relationship to verify the module's correctness?

   • AGenerate random inputs for principal, rate, and time, and compare the outputs to a spreadsheet model.
   • BCreate a test charter to explore the module's behavior with various financial scenarios.
   • CUse a checklist of common financial calculation errors to guide test input selection.
   • DUse metamorphic testing by running the module with a principal and then with double the principal, checking that the second output is twice the first.

   A team is testing a sorting algorithm. The expected output for a given input is not known, but the team knows that if the input list is reversed, the output should also be reversed. Which testing technique is most appropriate to verify the algorithm's correctness?

   • AExploratory testing with a charter to explore the sorting algorithm's behavior.
   • BRandom testing with a large number of random lists.
   • CMetamorphic testing using the relation that reversing the input should reverse the output.
   • DChecklist-based testing to ensure all sorting edge cases are covered.

   A company is considering using crowd testing for a new web application. The project manager is concerned about the quality of the test results and the ability to reproduce defects. Which of the following is a common limitation of crowd testing that the project manager should consider?

   • ACrowd testing can only be used for mobile applications.
   • BCrowd testing guarantees that all defects will be found.
   • CCrowd testing may produce results that are difficult to reproduce due to the variety of environments and testers.
   • DCrowd testing provides limited access to real devices.
