runner

runner

runner is a package that enables testing of functions that use the os/exec.Command() method for running commands.

By default, runner.New() returns an initialized os/exec.Command(). This contains the .Run() method that is defined in the Runner interface.

In your tests, you can create a interface with the .Run() method and have it return errors for negative testing, return nil for positive testing, and even have it panic to see how your program acts when unrecoverable errors are hit.
