Testing terraform-aws-ecr

This directory contains automated tests for the terraform-aws-ecr module. The tests use Terratest, a Go library that provides utilities for testing Terraform code.

Prerequisites

  1. Go (version 1.16 or later)
  2. Terraform (version 1.3.0 or later)
  3. AWS credentials configured (via environment variables, shared credentials file, or AWS IAM role)

Running the Tests

To run all tests:

cd test
go test -v

To run a specific test:

cd test
go test -v -run TestEcrBasicCreation

Test Structure

The test suite includes the following tests:

  1. Basic Repository Test: Tests the creation of a simple ECR repository with minimal configuration.

    • Verifies repository creation
    • Checks image tag mutability
    • Validates repository URL and ARN

  2. Complete Repository Test: Tests the creation of a fully configured ECR repository.

    • Verifies repository creation with all features
    • Validates repository policies
    • Checks lifecycle policies
    • Tests KMS encryption

Test Fixtures

The test fixtures are located in the fixtures directory:

  • fixtures/basic: A simple ECR repository configuration
  • fixtures/complete: A full-featured ECR repository configuration with policies and KMS encryption

AWS Resources

These tests create real AWS resources, which might incur costs. The tests use the force_delete = true option to ensure that repositories can be cleaned up even if they contain images.

All resources are tagged with Test = "true" for identification and are destroyed after the test completes. However, if a test fails, you may need to manually delete the resources.

CI/CD Integration

These tests can be run in GitHub Actions using the workflow defined in .github/workflows/test.yml.
