# os_env
|
|
|
|
Use the `os_env` InSpec audit resource to test the environment variables for the platform on which the system is running.
|
|
|
|
<br>
|
|
|
|
## Syntax
|
|
|
|
A `os_env` resource block declares an environment variable, and then declares its value:
|
|
|
|
describe os_env('VARIABLE') do
|
|
its('property') { should eq 1 }
|
|
end
|
|
|
|
where
|
|
|
|
* `('VARIABLE')` must specify an environment variable, such as `PATH`
|
|
* `matcher` is a valid matcher for this resource
|
|
|
|
<br>
|
|
|
|
## Examples
|
|
|
|
The following examples show how to use this InSpec audit resource.
|
|
|
|
### Test the PATH environment variable
|
|
|
|
describe os_env('PATH') do
|
|
its('split') { should_not include('') }
|
|
its('split') { should_not include('.') }
|
|
end
|
|
|
|
### Test Habitat environment variables
|
|
|
|
Habitat uses the `os_env` resource to test environment variables. The environment variables are first defined in a whitespace array, after which each environment variable is tested:
|
|
|
|
hab_env_vars = %w(HAB_AUTH_TOKEN
|
|
HAB_CACHE_KEY_PATH
|
|
HAB_DEPOT_URL
|
|
HAB_ORG
|
|
HAB_ORIGIN
|
|
HAB_ORIGIN_KEYS
|
|
HAB_RING
|
|
HAB_RING_KEY
|
|
HAB_STUDIOS_HOME
|
|
HAB_STUDIO_ROOT
|
|
HAB_USER)
|
|
|
|
hab_env_vars.each do |e|
|
|
describe os_env(e) do
|
|
its('content') { should eq nil }
|
|
end
|
|
end
|
|
|
|
<br>
|
|
|
|
## Matchers
|
|
|
|
For a full list of available matchers, please visit our [matchers page](https://www.inspec.io/docs/reference/matchers/).
|
|
|
|
### content
|
|
|
|
The `content` matcher return the value of the environment variable:
|
|
|
|
its('content') { should eq '/usr/local/bin:/usr/local/sbin:/usr/sbin:/usr/bin:/sbin' }
|
|
|
|
### split
|
|
|
|
The `split` matcher splits the value of the environment variable with the `:` deliminator (use the `;` deliminator if Windows):
|
|
|
|
its('split') { should include ('/usr/bin') }
|
|
|
|
Note: the `split` matcher returns an array including `""` for cases where there is a trailing colon (`:`), such as `dir1::dir2:`
