# json

Use the `json` InSpec audit resource to test data in a JSON file.

## Syntax

A `json` resource block declares the data to be tested. Assume the following JSON file:

    {
      "name" : "hello",
      "meta" : {
        "creator" : "John Doe"
      },
      "array": [
        "zero",
        "one"
      ]
    }

This file can be queried using:

    describe json('/path/to/name.json') do
      its('name') { should eq 'hello' }
      its(['meta','creator']) { should eq 'John Doe' }
      its(['array', 1]) { should eq 'one' }
    end

where

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

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

## Examples

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

### Test a cookbook version in a policyfile.lock.json file

      its(['cookbook_locks', 'omnibus', 'version']) { should eq('2.2.0') }
    end
