Testing and Validation

Use the real commands from the repository. Run them from the repository root.

This repository uses several test and validation types:

• Lint and syntax checks catch style, formatting, and Ansible syntax problems early.
• Unit tests verify isolated logic.
• Integration tests verify behavior across modules and runtime boundaries.
• Combined validation runs the standard main verification flow.
• Local deploy and E2E validation checks whether apps and deployment flows work in a realistic local stack.

Code Quality and Automated Checks

Use the following table to choose the right lint, syntax, unit, integration, or combined validation command for your change.

Validation Commands

Category	Command	What it does	When to use it
Lint	make lint	Runs the main lint checks for the repository.	Use this when you want a broad lint pass before pushing.
Syntax	make lint-ansible	Runs the Ansible syntax validation for playbook.yml.	Use this when you changed Ansible roles, inventories, or playbook-related files.
Lint tests	make test-lint	Runs the lint test suite inside the development environment.	Use this when you want CI-like lint validation.
Unit tests	make test-unit	Runs the unit test suite.	Use this when you changed Python logic or other isolated code paths.
Integration tests	make test-integration	Runs the integration test suite.	Use this when your change affects behavior across modules or runtime boundaries.
Combined validation	make test	Runs the main combined validation flow.	Use this whenever a change touches at least one file that is not .md or .rst, or before opening a Pull Request.

Local Deploy and End-to-End Checks

For the retry-loop policy, use Iteration as the SPOT. The table below is a command reference for the supported local deployment paths.

Local Validation Commands

Use the following table when you need realistic local deployment validation or app-level end-to-end checks.

Category	Command	What it does	When to use it
Local deploy	APPS=web-app-nextcloud make deploy-fresh-kept-app	Creates the needed inventory and deploys one app.	Single-app devices.yml path.
Local deploy	APPS=web-app-nextcloud make deploy-reuse-kept-app	Reuses an existing devices.yml inventory and redeploys one app quickly.	Fast reuse path.
Local deploy	APPS=web-app-nextcloud make deploy-reuse-purged-app	Reuses an existing devices.yml inventory, purges the entity first, and redeploys one app quickly.	Fast reuse path after a state reset.
Local deploy and E2E	APPS=web-app-matomo make deploy-fresh-purged-app	Runs a dedicated local validation flow for one app against the dev stack, creating and re-initializing the inventory first.	Baseline and recovery path.
Full local validation	make deploy-fresh-kept-all	Builds the broader local deployment flow across apps.	Broad coverage when you explicitly need it.
Local reset	make container-refresh-inventory	Recreates the local inventory without deploying apps.	Use this when your local inventory is broken or you want a clean reset.
Local cleanup	make container-purge-system	Deletes local deploy artifacts and cleanup data.	Use this only when you really want to remove local state.

Important:

• Some local deploy commands are destructive.
• Read reset/README.md, purge/README.md, or exec/README.md before using the matching helper.
• For act-based workflow checks, see Act Workflow Checks.
• After a successful local deploy, run make trust-ca and restart your browser.

Playwright

Playwright tests are part of deployment and end-to-end validation for web-* roles. They are not exposed here as a separate top-level make command.

To enable Playwright for a web-* role, provide:

• templates/playwright.env.j2
• files/playwright.spec.js

Use Contributing playwright.env.j2 and Contributing playwright.spec.js as the SPOT for the file-level contract and scenario requirements.

During the deploy stage, the shared test-e2e-playwright role:

• discovers the relevant app roles
• stages the test project
• renders the .env
• copies the role-local playwright.spec.js
• injects the shared package.json and playwright.config.js
• waits until the app is reachable
• runs Playwright in Docker

In practice, Playwright coverage is usually exercised through local deploy flows and deploy CI runs.

Testing Standards

Common

Treat these rules as the baseline for all validation categories below.

• Write tests in the tests folder.
• Use Python unittest for unit, integration, and lint tests.
• Do not write tests that only check whether a file contains a string.
• Do not write tests only for non-executable files such as .yml or .j2.
• Test the behavior that consumes the configuration.

Unit

• For touched *.py files, add or update unit tests in tests/unit.
• For touched *.py files, add or update integration tests in tests/integration.

Playwright

• Playwright tests are required for web-* roles.
• Use Contributing playwright.env.j2 and Contributing playwright.spec.js as the SPOT for role-local Playwright file requirements.

Development Procedure

• Analyze the code first.
• Build hypotheses before writing the test.
• Write or update the role-local Playwright files.
• Run it against a fresh pure Docker image.
• Add additional procedures when relevant, for example OIDC or Keycloak.

Minimum Requirements

• Follow the scenario requirements in Contributing playwright.spec.js.
