}You may write your test plans as JSON in the following ways:
-
By hand, as pure JSON files
-
Using some templating engine (ERB, Jinja, etc...)
-
With your favorite programming language (Ruby, Python, etc...)
It does not matter how you generate your test plan, as long as it results in a valid JSON file. Certainly it would be a good idea to write your test plans from within Capistrano/Fabric/Chef/Puppet. Since the difference between environments (development, staging, production) should be known by your deployment tool, it would be clever to let that tool decide which paths, users, permissions and addresses to write into the test plan file.
Bellow we give you some suggestions on how to generate your test plans more efficiently (because writting JSON by hand is boring):
require 'json'
tdi_plan = {
:app => {
:desc => 'Test role',
:acl => {'localhost' => {:port => [22, 80]}},
:http => {'globo.com' => {:code => 301}},
}
}
File.open('tdi.json', 'w').write(JSON.pretty_generate(tdi_plan))import json
tdi_plan = {
'app': {
'desc': 'Test role',
'acl': {'localhost': {'port': [22, 80]}},
'http': {'globo.com': {'code': 301}},
}
}
open('tdi.json', 'w').write(json.dumps(tdi_plan, indent=2))Use JSONLint site to validate your JSONs.
