# apt

Use the `apt` InSpec audit resource to verify Apt repositories on the Debian and Ubuntu platforms, and also PPA repositories on the Ubuntu platform.

<br>

## Syntax

An `apt` resource block tests the contents of Apt and PPA repositories:

    describe apt('path') do
      it { should exist }
      it { should be_enabled }
    end

where

* `apt('path')` must specify an Apt or PPA repository
* `('path')` may be an `http://` address, a `ppa:` address, or a short `repo-name/ppa` address
* `exist` and `be_enabled` are a valid matchers for this resource

<br>

## Examples

The following examples show how to use this InSpec audit resource.

### Test if apt repository exists and is enabled

    describe apt('http://ppa.launchpad.net/juju/stable/ubuntu') do
      it { should exist }
      it { should be_enabled }
    end

### Verify that a PPA repository exists and is enabled

    describe apt('ppa:nginx/stable') do
      it { should exist }
      it { should be_enabled }
    end

### Verify that a repository is not present

    describe apt('ubuntu-wine/ppa') do
      it { should_not exist }
      it { should_not be_enabled }
    end
