SNFR2 - E2E Testing

ID: SNFR2 - Category: Testing - E2E Testing

Modules MUST implement end-to-end (deployment) testing that create actual resources to validate that module deployments work. In Bicep tests are sourced from the directories in /tests/e2e. In Terraform, these are in /examples.

Each test MUST run and complete without user inputs successfully, for automation purposes.

Each test MUST also destroy/clean-up its resources and test dependencies following a run.

Resources/Dependencies Required for E2E Tests

It is likely that to complete E2E tests, a number of resources will be required as dependencies to enable the tests to pass successfully. Some examples:

• When testing the Diagnostic Settings interface for a Resource Module, you will need an existing Log Analytics Workspace to be able to send the logs to as a destination.
• When testing the Private Endpoints interface for a Resource Module, you will need an existing Virtual Network, Subnet and Private DNS Zone to be able to complete the Private Endpoint deployment and configuration.

Module owners MUST:

• Create the required resources that their module depends upon in the test file/directory
  • They MUST either use:
    • Simple/native resource declarations/definitions in their respective IaC language,
      OR
    • Another already published AVM Module that MUST be pinned to a specific published version.
      • They MUST NOT use any local directory path references or local copies of AVM modules in their own modules test directory.

resource "azurerm_resource_group" "example" {
  name     = "rsg-test-001"
  location = "West Europe"
}

resource "azurerm_log_analytics_workspace" "example" {
  name                = "law-test-001"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  sku                 = "PerGB2018"
  retention_in_days   = 30
}

resource logAnalyticsWorkspace 'Microsoft.OperationalInsights/workspaces@2021-12-01-preview' = {
  name: 'law-test-001'
  location: resourceGroup().location
  properties: {
    sku: {
      name: 'PerGB2018'
    }
    retentionInDays: 30
  }
}

Skipping Deployments (SHOULD NOT)

Deployment tests are an important part of a module’s validation and a staple of AVM’s CI environment. However, there are situations where certain e2e-test-deployments cannot be performed against AVM’s test environment (e.g., if a special configuration/registration (such as certain AI models) is required). For these cases, the CI offers the possibility to ‘skip’ specific test cases by placing a file named .e2eignore in their test folder.

The test is skipped, as only one instance of this service can be deployed to a subscription.
