This allows them to write shorter test cases, and retrieve the same accurate results as provided by unit tests in Golang. This program consists of two goroutines. The first goroutine is implicit and is the main function itself. The second goroutine is created when we call go f(0). Normally when we invoke a function our program will execute all the statements in a function and then return to the next line following the invocation.
