Download Testing Infrastructure

[Integer-Ctrl]

Currently, only the download of a collection and downloads using SPARQL queries are tested, and these tests are very basic. To ensure reliability, the client needs more complete automated tests for all download features.

Proposed features:

• Improve existing tests
  • e.g., verify SHASUM of all downloaded files
• Test all download features and CLI options
• Add tests for intended failures (e.g., non-existing resources, missing permissions)

Advanced:
Currently, the download tests depend on the remote Databus server. This effectively makes them integration tests rather than isolated unit tests. A better approach would be to create a local dummy Databus for testing core functionality offline.
This could include:

• A local HTTP server simulating Databus responses
• A small dummy dataset with the structure account/group/artifact/version and a collection example to test all the download features
