Test-driven development in Perl involves writing unit tests with modern frameworks like Test2::V0 before implementation. You can structure tests using subtests, perform deep comparisons, and handle exceptions to ensure code correctness and maintainability.

Mocking external dependencies in Perl tests isolates modules from external APIs and services. Using modern testing patterns, you can simulate various scenarios and verify behavior without actual network calls, ensuring robust error handling.

Measure Perl code coverage using Devel::Cover to analyze which parts of your modules are exercised by tests. This ensures your test suites comprehensively validate code paths and fulfill robust validation requirements.

Yes, Test2::V0 supports deep comparison and subtests for Perl unit testing. It allows developers to structure complex test suites, verify nested data structures, and handle exceptions within modern testing workflows.

Validate Perl scripts before deployment by building robust test suites that check correctness and handle errors. Using modern testing frameworks and patterns ensures your scripts meet integration testing and maintainability requirements.

Use mocking in Perl integration testing when you need to isolate dependencies and verify behavior under various scenarios without triggering external side effects. This approach ensures robust validation and maintainability for complex module interactions.
