# aws\_sns\_subscription

Use the `aws_sns_subscription` InSpec audit resource to test detailed properties of a AWS SNS Subscription.

<br>

## Syntax

An `aws_sns_subscription` resource block uses resource parameters to search for a SNS Subscription, and then tests that subscriptions properties.  If no Subscriptions match, no error is raised, but the `exists` matcher will return `false` and all properties will be `nil`.

    describe aws_sns_subscription('arn:aws:sns:us-east-1::test-topic-01:b214aff5-a2c7-438f-a753-8494493f2ff6') do
      it { should exist }
    end

<br>

## Examples

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

As this is the initial release of `aws_sns_subscription`, its limited functionality precludes examples.

<br>

## Resource Parameters

This InSpec resource accepts the following parameters, which are used to search for the Security Group.

### subscription\_arn

The ARN (Amazon Resource Name) of the AWS SNS Subscription.

    # Using Hash syntax
    describe aws_sns_subscription(subscription_arn: 'arn:aws:sns:us-east-1::test-topic-01:b214aff5-a2c7-438f-a753-8494493f2ff6') do
      it { should exist }
    end

    # Or omit hash syntax, rely on it being the default parameter
    describe aws_sns_subscription('arn:aws:sns:us-east-1::test-topic-01:b214aff5-a2c7-438f-a753-8494493f2ff6') do
      it { should exist }
    end

<br>

## Matchers

### exists

The control will pass if the specified Aws Subscription was found.  Use should_not if you want to verify that the specified Subscription does not exist.

    # Test that a specific subscription exists.
    describe aws_sns_subscription(subscription_arn: 'arn:aws:sns:us-east-1::test-topic-01:b214aff5-a2c7-438f-a753-8494493f2ff6')
      it { should exist }
    end

    # Test that a Subscription does not exist.
    describe aws_sns_subscription(subscription_arn: 'arn:aws:sns:us-east-1::NOGOOD:b214aff5-a2c7-438f-a753-8494493f2ff6')
      it { should_not exist }
    end

### be\_confirmation\_authenticated

Provides whether or not the subscription confirmation request was authenticated.

    describe aws_sns_subscription(subscription_arn: 'arn:aws:sns:us-east-1::NOGOOD:b214aff5-a2c7-438f-a753-8494493f2ff6')
      it { should be_confirmation_authenticated }
    end

### have\_raw\_message\_delivery

Provides whether or not the original message is passed as is, not formatted as a json or yaml.

    describe aws_sns_subscription(subscription_arn: 'arn:aws:sns:us-east-1::NOGOOD:b214aff5-a2c7-438f-a753-8494493f2ff6')
