+Feature: Extracting Metadata for Azure App Service
+
+  Background:
+    Given an instrumented application is configured to collect cloud provider metadata for azure
+
+  Scenario Outline: Azure App Service with all environment variables present in expected format
+    Given the following environment variables are present
+      | name                   | value                |
+      | WEBSITE_OWNER_NAME     | <WEBSITE_OWNER_NAME> |
+      | WEBSITE_RESOURCE_GROUP | resource_group       |
+      | WEBSITE_SITE_NAME      | site_name            |
+      | WEBSITE_INSTANCE_ID    | instance_id          |
+    When cloud metadata is collected
+    Then cloud metadata is not null
+    And cloud metadata 'account.id' is 'f5940f10-2e30-3e4d-a259-63451ba6dae4'
+    And cloud metadata 'provider' is 'azure'
+    And cloud metadata 'instance.id' is 'instance_id'
+    And cloud metadata 'instance.name' is 'site_name'
+    And cloud metadata 'project.name' is 'resource_group'
+    And cloud metadata 'region' is 'AustraliaEast'
+    Examples:
+      | WEBSITE_OWNER_NAME                                                                          |
