In a Go project, you encounter a situation where certain test cases are dependent on external resources such as databases. How would you handle such dependencies to ensure test reliability and efficiency?

Mocking frameworks allow developers to simulate interactions with external resources, such as databases, during testing. By mocking database responses, tests can be run without relying on actual external resources, ensuring test reliability and efficiency. Running tests directly against the production database is not recommended as it can lead to data corruption and inconsistent test results. Skipping tests or manually setting up separate test databases are not optimal solutions as they either compromise test coverage or require manual effort, leading to inefficiencies.
