Dependency Graph With Diamond Dependencies (JSON)

An explicit node/edge dependency graph with in-degree, out-degree and depth precomputed, plus a diamonds array naming the two shared nodes and their parents — the reference answer for any graph builder run against the SBOMs and lockfiles here. Every package, version, hash and licence is fictional — the tree describes nothing real.

Testing contract

Reference control

Scenario: Score a dependency-graph builder against a known topology.
Expected result: Builder produces 10 nodes and 10 edges, gives example-logger an in-degree of 3, and reports a maximum depth of 2.

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 Diamond Dependencies (JSON)” is a deterministic Novus Examples fixture for JSON parsing, Graph data, Conversion testing. Flat, deeply nested, JSON Lines, and intentionally invalid JSON for testing parsers and error handling.

Documented properties for this file: seed 51200 · 10 nodes · 10 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.
