You're leading a project that requires extensive testing with a large number of test cases and the need for test parallelization. Which testing framework in Go would you recommend to ensure efficient testing?

Ginkgo stands out in scenarios requiring extensive testing and parallelization due to its built-in support for parallel test execution. Ginkgo's parallel test runner allows you to run tests concurrently, which can significantly reduce the overall test execution time, especially when dealing with a large number of test cases. This makes Ginkgo a preferred choice for projects where efficient testing is a priority.
