   How does an external authentication service dependency affect the design of automated API tests?

   • ATests must include steps to obtain and manage authentication tokens
   • BTests can ignore authentication because it is handled by the network
   • CTests must be written in a specific programming language
   • DTests should avoid using any test data

   A team is automating tests for a public API that depends on a third-party payment gateway. The payment gateway has a rate limit of 100 requests per minute. The team's test suite makes 500 API calls to the payment gateway in a single run. The team wants to run the tests in CI without hitting the rate limit. What is the best strategy?

   • AMock the payment gateway in all tests to avoid rate limits.
   • BUse service virtualization to simulate the payment gateway for most tests, and run a small set of real integration tests against the gateway.
   • CRun the tests sequentially with a delay between requests to stay under the rate limit.
   • DIncrease the rate limit by contacting the payment gateway provider.

   A team is automating tests for an API that depends on a legacy mainframe system. The mainframe is only available during business hours, but the team wants to run tests in CI at any time. What is the best approach?

   • AUse a test environment that has a direct connection to the mainframe.
   • BSkip tests that depend on the mainframe in CI and run them only in a nightly batch.
   • CSchedule CI runs only during business hours when the mainframe is available.
   • DUse service virtualization to simulate the mainframe's responses in the CI environment.

   A team is automating tests for an API that requires an OAuth2 token from an external identity provider. The token expires every 30 minutes, and the test suite runs longer than that. The team wants to avoid test failures due to token expiration. What is the best approach?

   • AMock the identity provider so that token validation always succeeds.
   • BImplement a test hook that refreshes the token automatically when it is about to expire.
   • CRun each test case in a separate test suite so that each gets a fresh token.
   • DHard-code a long-lived token in the test configuration to avoid expiration.

   A team is automating tests for a data-processing API that reads from a database and writes to a message queue. The database is shared with other teams, and the message queue is also used by other applications. The team wants to run tests in a shared environment without affecting other teams. What is the most effective strategy?

   • AMock the database and the message queue in the tests.
   • BUse the shared database but clean up test data after each test run.
   • CCoordinate with other teams to schedule test runs during off-peak hours.
   • DUse a dedicated test database and a separate test queue for the automated tests.
