Summary by CodeRabbit

• Tests
  • Expanded test coverage for CLI deploy and download commands, including help output and edge cases.
  • Added integration-style tests for downloading collections, versions, and artifacts, plus full authentication flows.
  • Improved validation of error handling for missing/invalid options, special characters, and path/URI variations.
  • Enhanced coverage for vault-based authentication, redirects, and authenticated vs. unauthenticated downloads.
  • Ensures parameters are passed correctly across commands and that non-zero exits occur on invalid usage.

Walkthrough

Added two new pytest modules providing comprehensive CLI and download/vault authentication test coverage. Tests mock databusclient operations, validate argument propagation, error handling, help output, special characters, and integration-like flows for deploy and download commands. No production code or public API changes.

Changes

Cohort / File(s)	Summary
CLI test suite tests/test_cli.py	Introduces extensive tests for click-based CLI: deploy and download commands, required option validation, multiple distributions handling, endpoint/auth parameters, SPARQL queries, help output, edge cases (special chars, unicode, spaces), exception paths, and integration-style flows using mocks.
Download and vault tests tests/test_download.py	Adds tests for URI parsing, artifact/version handling, vault token sourcing (file/env), HTTP URL handling, redirect and 401 flows, authenticated/unauthenticated downloads, and group/artifact workflows; includes negative/error scenarios and utilities.

Estimated code review effort

Poem

I thump the keys with whiskered glee,
New tests sprout up like clover free.
Deploys and downloads hop in line,
Vaults unlock, the tokens shine.
With mocks and args all neatly set—
Our burrow’s safer yet. 🐇✅

🔇 Additional comments (16)

tests/test_download.py (11)

32-114: LGTM! Comprehensive URI parsing test coverage.

The test suite for __get_databus_id_parts__ covers various URI formats including full file URIs, version URIs, artifact URIs, group URIs, account URIs, and edge cases like trailing slashes and missing protocols. The assertions properly validate all six returned components.

---

187-241: LGTM! Thorough version extraction test coverage.

The test suite properly validates version extraction including single versions, multiple versions with sorting, numeric date sorting, error handling for missing versions, and handling of versions without @id fields.

---

243-305: LGTM! Well-structured artifact extraction tests.

The test suite effectively validates artifact extraction including single/multiple artifacts, proper filtering of versioned artifacts (lines 272-286), empty lists, and handling of missing @id fields.

---

307-435: LGTM! Comprehensive vault authentication test coverage.

The test suite effectively validates the two-step OAuth flow:

1. Refresh token exchange for access token
2. Token exchange for vault access token

Tests cover multiple token sources (file, environment variable), URL formats (HTTPS, HTTP, no protocol), error handling, and proper audience extraction from vault URLs.

---

437-574: LGTM! Thorough file download test coverage.

The test suite comprehensively validates file download scenarios including:

• Basic download without authentication
• Redirect handling
• 401 authentication flow with vault token acquisition
• Error handling for missing tokens when auth is required
• HTTP error propagation

The mocking strategy properly isolates the unit under test.

---

576-738: LGTM! Comprehensive download function test coverage.

The test suite validates the main download function across various input types:

• Direct file URIs (with and without vault authentication)
• Version URIs (expanding to multiple files)
• Artifact URIs (resolving to latest version)
• Collections (via SPARQL query)
• Direct SPARQL queries
• Error handling (query without endpoint)
• Directory structure creation

The tests properly verify parameter propagation and mocking strategy.

---

740-773: LGTM! Well-structured SHA256 hash tests.

The test suite validates the wsha256 function with various input types including empty strings, simple strings, unicode characters, special characters, and consistency checks. The tests properly verify the 64-character hex output format.

---

775-806: LGTM! Collection handler tests properly validate HTTP headers.

The tests verify that __handle_databus_collection__ requests collections with the correct Accept: text/sparql header and returns the SPARQL query text. Good coverage of the HTTP interaction.

---

808-843: LGTM! JSON-LD fetching tests validate correct HTTP headers.

The tests verify that __get_json_ld_from_databus__ requests data with the correct Accept: application/ld+json header and properly returns the JSON-LD response text. Good validation of both simple and complex JSON-LD structures.

---

845-934: LGTM! Comprehensive integration-style tests.

The integration tests validate complex scenarios including:

• Group downloads with multiple artifacts (with proper mock chaining for nested calls)
• Multiple file URIs in a single download call
• Mixed input types (direct URIs and SPARQL queries)

The tests properly verify the expected number of download calls and parameter propagation through the mock chain.

---

173-184: Behavior confirmed: missing file attributes result in None entries.
The implementation appends None for Parts without a file attribute, matching the test’s expectation.

tests/test_cli.py (5)

8-127: LGTM! Comprehensive deploy command test coverage.

The test suite effectively validates the deploy command including:

• Basic successful deployment
• Required option validation (versionid, title, distributions)
• Multiple distribution handling with proper argument extraction (lines 103-105)
• Output message verification

The use of Click's CliRunner for testing is appropriate and the mocking strategy properly isolates the CLI layer from the client implementation.

---

129-303: LGTM! Thorough download command test coverage.

The test suite comprehensively validates the download command across various scenarios:

• Single and multiple URIs
• Custom local directories and endpoints
• Vault authentication parameters (token file, auth URL, client ID)
• Default authentication values
• SPARQL query handling
• Missing URI error handling
• Combined options validation

The mocking strategy properly isolates the CLI from the download implementation. Note: Static analysis warnings about "hardcoded passwords" on lines 209 and 300 are false positives—these are test assertions validating parameter passing, not actual secrets.

---

305-343: LGTM! Help message tests ensure documentation is present.

The tests verify that help output includes essential information:

• Main CLI help lists available commands
• Deploy help documents all required options
• Download help documents URI, directory, and authentication options

This ensures users can discover command usage through --help flags.

---

345-425: LGTM! Edge case tests validate robustness.

The test suite validates handling of edge cases including:

• Special characters in arguments (quotes, apostrophes, ampersands, unicode)
• Spaces in file paths
• Unicode in URIs
• Exception propagation from underlying client functions

Note: Lines 388-398 allow either success or error for unicode URIs (assert result.exit_code == 0 or 'error' in result.output.lower()), which might be acceptable if unicode handling varies by platform.

Static analysis warnings about unused parameters on lines 401 and 417 are false positives—the mock objects are configured via @patch decorators with side_effect and don't need to be explicitly used in the test body.

---

427-488: LGTM! Integration tests validate end-to-end CLI workflows.

The integration tests verify realistic usage scenarios:

• Downloading collections
• Downloading specific versions
• Downloading artifacts (latest version)
• Complete vault authentication workflow with all required parameters

The tests properly validate that URIs are passed correctly and authentication parameters are propagated through the CLI to the download function. Static analysis warning on line 487 is a false positive (test assertion, not a secret).
