…tion - Fix tests.yaml: remove escaped underscore (00-n8n\_basic.rb -> 00-n8n_basic.rb) - Rewrite tests to use standard RSpec framework (lib/community/app_handler) - Add comprehensive tests matching actual appliance: * Docker installation and service status * n8n container image availability (n8nio/n8n:latest) * Data directory existence (/data) * Container running status (n8n-container) * Container responsiveness * Container restart policy (unless-stopped) * Port mapping (5678:5678) * Volume mapping (/data:/home/node/.n8n) * oneapps MOTD verification (required test) - Remove old test framework that doesn't exist in marketplace
Add missing newline at end of file to comply with yamllint rules.
The user_inputs should be a dictionary (key: value), not an array. Changed keys to lowercase with oneapp_ prefix to match OpenNebula conventions: - CONTAINER_NAME -> oneapp_container_name - CONTAINER_PORTS -> oneapp_container_ports - CONTAINER_ENV -> oneapp_container_env - CONTAINER_VOLUMES -> oneapp_container_volumes Updated inputs_order to match the new uppercase context variable names.
Set ONE_SERVICE_VERSION='latest' instead of leaving it empty. This fixes the build script metadata.
Use proper version number '1.0' instead of 'latest' for the appliance version.
- Add wait period for contextualization to complete (60s initial + up to 120s for Docker) - Fix template parsing error in volume mount test (use single quotes for docker format) - Fix app_handler.rb context escaping (add quotes around context value and use consistent escaping) The tests now properly wait for Docker service to start and the n8n container to be created before running validation checks.
- Fix metadata.yaml structure to match test framework requirements - Change :os: from array to hash with :type and :base - Change :hypervisor: from array to single value - Add 1️⃣ section with template configuration - Add :infra: section with disk_format and apps_path - Add generated context.yaml for n8n appliance All 9 tests passing successfully.
