Using third-party testing tools

There are a number of helpful tools for Go testing. Tools that make it easier to get an idea of code coverage at a per-function level, tools to do assertions to reduce testing lines of code, and test runners. This recipe will cover github.com/axw/gocov and github.com/smartystreets/goconvey packages to demonstrate some of this functionality. There are a number of other notable test frameworks depending on your needs. The github.com/smartystreets/goconvey package supports both assertions and is a test runner. It used to be the cleanest way to have labeled subtests prior to Go 1.7.
