+# google\_organization
+
+Use the `google_organization` InSpec audit resource to test properties of a GCP organization.  
+
+<br>
+
+## Syntax
+
+Google organization have a name, display name (or domain) and lifecycle state. For more info, please see [here](https://cloud.google.com/resource-manager/docs/creating-managing-organization).
+
+A `google_organization` resource block declares the tests for a single GCP organization identified by `display_name` or `name`:
+
+    describe google_organization(display_name: 'google.com') do
+      it { should exist }
+      its('name') { should eq 'organizations/1234'  }
+      its('display_name') { should eq 'google.com' }
+    end
+
+    describe google_organization(name: 'organizations/1234') do
+      it { should exist }
+      its('name') { should eq 'google.com'  }
+      its('lifecycle_state') { should eq 'ACTIVE' }
+    end
+
+<br>
+
+## Examples
+
+The following examples show how to use this InSpec audit resource.
+
+### Test that a GCP organization has the expected name
+
+    describe google_organization(name: 'organizations/1234') do
+      its('name') { should eq 'organizations/1234' }
+    end
+
+### Test that a GCP organization has the expected lifecycle state e.g. "ACTIVE"
+
+    describe google_organization(display_name: 'google.com') do
+      its('lifecycle_state') { should eq "ACTIVE" }
+    end
+
+<br>
+
+## Properties
+
+*  `name`, `display_name`, `lifecycle_state`
+
+<br>
+
+
+## GCP Permissions
+
+Ensure the [Cloud Resource Manager API](https://console.cloud.google.com/apis/library/cloudresourcemanager.googleapis.com/) is enabled for the project.

+# google\_organizations
+
+Use the `google_organizations` InSpec audit resource to test properties of all, or a filtered group of, GCP 
+organizations.
+
+<br>
+
+## Syntax
+
+A `google_organizations` resource block collects GCP organizations then tests that group.
+
+    describe google_organizations do
+      it { should exist }
+    end
+
+Use this InSpec resource to enumerate IDs then test in-depth using `google_organization`.
+
+    google_organizations.names.each do |name|
+      describe google_organization(name: name) do
+        it { should exist }
+        its('lifecycle_state') { should eq "ACTIVE" }
+      end
+    end
+
+<br>
+
+## Examples
+
+The following examples show how to use this InSpec audit resource.
+
+### Test that there are no more than a specified number of organizations available
+
+    describe google_organizations do
+      its('count') { should be <= 100}
+    end
+
+### Test that an expected organization name is available
+
+    describe google_organizations do
+      its('names') { should include "organization/1234" }
+    end
+
+### Test that an expected organization display name is available
+
+    describe google_organizations do
+      its('display_names') { should include "google.com" }
+    end
+
+### Test that all organizations are ACTIVE
+
+    describe google_organizations do
+      its('lifecycle_state'){ should eq 'ACTIVE' }
+    end    
+
+### Test that a particular subset of ACTIVE organizations with display name 'goog*' exist
+
+    google_organizations.where(display_name: /^goog/, lifecycle_state: 'ACTIVE').names.each do |name|
+      describe google_organization(name: name) do
+        it { should exist }
+      end
+    end
+
+<br>
+
+## Filter Criteria
+
+This resource supports the following filter criteria:  `name`; `display_name` and `lifecycle_state`. Any of these may be used with `where`, as a block or as a method.
+
+## Properties
+
+*  `names` - an array of google_organization identifier strings
+*  `display_names` - an array of google_organization display name strings
+*  `lifecycle_state`- an array of google_organization lifecycle state strings
+
+<br>
