# cpan
|
|
|
|
Use the `cpan` InSpec audit resource to test Perl modules that are installed by system packages or the CPAN installer.
|
|
|
|
<br>
|
|
|
|
## Syntax
|
|
|
|
A `cpan` resource block declares a package and (optionally) a package version:
|
|
|
|
describe cpan('package_name') do
|
|
it { should be_installed }
|
|
end
|
|
|
|
where
|
|
|
|
* `'package_name'` is the name of the package, such as `'DBD::Pg'`
|
|
* `be_installed` tests to see if the package described above is installed
|
|
