# yaml

Use the `yaml` InSpec audit resource to test configuration data in a Yaml file.

## Syntax

A `yaml` resource block declares the configuration data to be tested. Assume the following Yaml file:

    name: foo
    array:
      - zero
      - one

This file can be queried using:

    describe yaml do
      its('name') { should eq 'foo' }
      its(['array', 1]) { should eq 'one' }
    end

where

* `name` is a configuration setting in a Yaml file
* `should eq 'foo'` tests a value of `name` as read from a Yaml file versus the value declared in the test


## Matchers

This InSpec audit resource has the following matchers:

### be

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

### cmp

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

### eq

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

### include

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

### match

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

### name

The `name` matcher tests the value of `name` as read from a Yaml file versus the value declared in the test:

    its('name') { should eq 'foo' }

## Examples
