# gem
|
|
|
|
Use the `gem` InSpec audit resource to test if a global Gem package is installed.
|
|
|
|
<br>
|
|
|
|
## Syntax
|
|
|
|
A `gem` resource block declares a package and (optionally) a package version:
|
|
|
|
describe gem('gem_package_name', 'gem_binary') do
|
|
it { should be_installed }
|
|
end
|
|
|
|
where
|
|
|
|
* `('gem_package_name')` must specify a Gem package, such as `'rubocop'`
|
|
* `('gem_binary')` can specify the path to a non-default gem binary, defaults to `'gem'`
|
|
* `be_installed` is a valid matcher for this resource
|
|
|
|
