What are Datadir tests in the context of Keboola?

Datadir tests are the primary functional testing method for Keboola components. They mirror the production environment's directory structure (in/out tables, config, state) to verify the complete component workflow.

How does this skill handle external API dependencies?

The skill uses mocking patterns (specifically unittest.mock) to simulate API responses, allowing you to test components in isolation without needing real credentials or internet access.

Can I test incremental loading and state management?

Yes, the skill includes specific patterns for setting up in/state.json and verifying that out/state.json is updated correctly for subsequent runs.

Does it support CSV manifest validation?

Absolutely. It provides assertions to verify that manifest files are generated with the correct primary keys, incremental flags, and table metadata.

What testing frameworks does this skill use?

It is optimized for use with Python's unittest and pytest frameworks, utilizing the uv package manager for running tests and managing dependencies.
