yarn.lock (Classic v1)

A Yarn 1 lockfile in its own line-oriented grammar — quoted descriptor headers, two-space indented fields, resolved URLs with a SHA-1 fragment — which looks like YAML but is not. Every package, version, hash and licence is fictional — the tree describes nothing real.

Testing contract

Expected to pass

Scenario: Parse a Yarn Classic lockfile with a parser that is not a YAML parser.
Expected result: All 9 fictional entries resolve with version, resolved URL, sha512 integrity and their declared dependency ranges.

What is a .lock file?

A .lock file pins the exact dependency graph a package manager resolved, so a later install reproduces it byte for byte. Cargo.lock and Poetry's poetry.lock use TOML, Gemfile.lock and yarn.lock use their own line-oriented grammars, and all of them record resolved versions, source registries, integrity hashes, and the transitive edges between packages. It is committed alongside the human-edited manifest, which states ranges rather than exact versions.

How to use this file

Use an example .lock file to test dependency parsers, SBOM generators, and vulnerability scanners, verifying that transitive dependencies and integrity hashes are read correctly and that a pinned version is never confused with the range declared in the manifest.

How to use this file for testing

“yarn.lock (Classic v1)” is a deterministic Novus Examples fixture for Config parsing, Conversion testing, Editor testing. TOML and INI configuration files with nested sections and typed values — for testing config parsers and loaders.

Documented properties for this file: seed 51200 · 9 entries · 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.

Point your config loader at the file and assert it reads the documented sections and typed values, including any deliberately-tricky nesting or comments.
