Develop pattern for integration testing

[sebastus]

integration testing may use terratest, but in general the pattern is:

• create some resources using rovergo
• validate them somehow
• tear them down
• emit pass/fail stats

Looking at how the various pkgs can be refactored as interfaces so that mocks can be written.

[sebastus]

Initial unit test has 99.9% of what's needed to do an integration test. One line of code has to change: (file is runFromCLI_test.go)

    getActionMap()
    action := cmd.ActionMap["mock"]
    console.DebugEnabled = true
    action.Execute(&optionsList[0])

to:

    getActionMap()
    action := cmd.ActionMap[cmd.Name()]    <-- this 
    console.DebugEnabled = true
    action.Execute(&optionsList[0])
