   A team is automating unit tests for a financial calculation library. The tests currently have low code coverage and are difficult to maintain because they are tightly coupled to implementation details. What is the best way to improve the maintainability of the test code?

   • AUse a single large test class for all tests to reduce file count.
   • BRefactor tests to focus on behavior and public interfaces rather than internal implementation.
   • CWrite tests only for new features and skip existing code.
   • DIncrease the number of tests that check private methods directly.

   Why is mocking dependencies important in unit test automation?

   • ATo ensure the tests run in a specific order.
   • BTo make the tests work on multiple browsers.
   • CTo isolate the unit under test from external dependencies like databases or web services.
   • DTo make the tests run faster by skipping assertions.

   A team is automating unit tests for a risk assessment module that uses a random number generator to simulate market conditions. The tests are flaky because the random values sometimes cause extreme scenarios that are hard to assert. What is the best way to make the tests deterministic?

   • ARun the tests multiple times and ignore failures that do not reproduce.
   • BInject a seeded random number generator into the module so tests can control the sequence.
   • CUse a real random number generator but increase the test timeout to avoid failures.
   • DRemove the random number generator from the module and use a fixed value.

   A QA team is automating API tests for a payment gateway. The API requires an OAuth 2.0 token that expires every 15 minutes, and the token is obtained by calling an authentication endpoint. The test suite runs continuously in CI. What is the best way to handle token expiration in the automated tests?

   • AImplement a helper function that requests a new token when the current one expires or before each test run.
   • BDisable authentication in the test environment so tests can run without tokens.
   • CRun tests only within the 15-minute validity window and schedule them accordingly.
   • DHard-code a long-lived token in the test configuration to avoid frequent re-authentication.
