Dependency Graph With a Cycle (JSON)

A dependency graph containing a genuine three-node cycle between fictional plugins — the fixture that makes a naive recursive walker hang or blow the stack, with the cycle path stated so the expected answer is unambiguous. Every package, version, hash and licence is fictional — the tree describes nothing real.

Testing contract

Expected to recover

Scenario: Traverse a dependency graph that contains a cycle.
Expected result: Walker terminates, reports the cycle a -> b -> c -> a, and does not recurse infinitely or duplicate example-logger.

What is a .json file?

JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format representing objects, arrays, strings, numbers, booleans, and null. It is language-independent, human-readable, and the dominant format for web APIs and configuration. It requires a single well-formed root value.

How to use this file

Use an example JSON file to test parsers and serializers, schema validation, Unicode and number-precision handling, and API request or response processing.

How to use this file for testing

“Dependency Graph With a Cycle (JSON)” is a deterministic Novus Examples fixture for JSON parsing, Graph data, Error handling. Flat, deeply nested, JSON Lines, and intentionally invalid JSON for testing parsers and error handling.

Documented properties for this file: seed 51200 · 5 nodes · 5 edges · LF. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

SBOM, lockfile, provenance, and advisory fixtures describe the same fabricated component tree across formats, so a converter or scanner can be diffed against a known answer. Every package name, version, hash, and advisory ID is invented — never treat a finding here as real.

Feed the file to your parser and assert it handles the documented quirks — quoted delimiters, embedded newlines, ragged rows, or invalid syntax; the valid↔invalid distinction is labelled in the title.
