   A development team is using Test-Driven Development (TDD) to implement a new feature. They write a test that fails, then write the minimal code to make it pass, and then refactor. What is the primary benefit of this approach?

   • AIt ensures that the code is 100% bug-free before release.
   • BIt allows testers to write tests without understanding the requirements.
   • CIt provides immediate feedback on the code's behavior and guides the design of the code.
   • DIt eliminates the need for any other testing levels, such as system or acceptance testing.

   • BConducting integration testing of the modules as they are developed.
   • CExecuting component tests on the individual modules.
   • DWriting system test cases based on the system requirements.

   A developer is practicing TDD for a new function that calculates discounts. They write a test for a 10% discount on orders over $100. The test fails because the function is not implemented. What should the developer do next?

   • ASkip the test and implement the full discount logic to save time.
   • BAsk a tester to write the test instead, to ensure independence.
   • CImplement the minimal code to make the test pass, even if it is not the final solution.
   • DWrite a more comprehensive test that covers all discount scenarios before implementing the code.

   A company is developing a new mobile banking app. The project manager wants to ensure that testing activities start as early as possible to reduce the cost of defect fixing. The team is currently in the requirements gathering phase. Which approach best aligns with the goal of early testing?

   • AAsk developers to write unit tests first, and then have testers review the unit tests to ensure they are comprehensive.
   • BBegin testing only after the code is integrated, as this is the first point where the system can be executed and validated.
   • CWait until the design phase is complete, then begin test planning and design based on the detailed design documents.
   • DStart test planning and design during the requirements phase, and involve testers in reviewing requirements for testability and potential defects.
