title: About the package Resource

# package

Use the `package` InSpec audit resource to test if the named package and/or package version is installed on the system.


# Syntax

A `package` resource block declares a package and (optionally) a package version:

    describe package('name') do
      it { should be_installed }
    end

where

* `('name')` must specify the name of a package, such as `'nginx'`
* `be_installed` is a valid matcher for this resource

# Matchers

This InSpec audit resource has the following matchers:

## be

<%= partial "/shared/matcher_be" %>

## be_installed

The `be_installed` matcher tests if the named package is installed on the system:

    it { should be_installed }

## cmp

<%= partial "/shared/matcher_cmp" %>

## eq

<%= partial "/shared/matcher_eq" %>

## include

<%= partial "/shared/matcher_include" %>

## match

<%= partial "/shared/matcher_match" %>

## version

The `version` matcher tests if the named package version is on the system:

    its('version') { should eq '1.2.3' }

# Examples

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

## Test if nginx version 1.9.5 is installed

    describe package('nginx') do
      it { should be_installed }
      its('version') { should eq 1.9.5 }
    end

## Test that a package is not installed

    describe package('some_package') do
      it { should_not be_installed }
    end

## Test if telnet is installed

    describe package('telnetd') do
      it { should_not be_installed }
    end

    describe inetd_conf do
      its('telnet') { should eq nil }
    end

## Test if ClamAV (an antivirus engine) is installed and running

    describe package('clamav') do
      it { should be_installed }
      its('version') { should eq '0.98.7' }
    end

    describe service('clamd') do
      it { should_not be_enabled }
      it { should_not be_installed }
      it { should_not be_running }
    end

## Verify if Memcached is installed, enabled, and running

Memcached is an in-memory key-value store that helps improve the performance of database-driven websites and can be installed, maintained, and tested using the `memcached` cookbook (maintained by Chef). The following example is from the `memcached` cookbook and shows how to use a combination of the `package`, `service`, and `port` InSpec audit resources to test if Memcached is installed, enabled, and running:

    describe package('memcached') do
      it { should be_installed }
    end

    describe service('memcached') do
      it { should be_installed }
      it { should be_enabled }
      it { should be_running }
    end

    describe port(11_211) do
      it { should be_listening }
    end
