@lacspace/snapshot
Snapshot testing without a framework — a stable, deterministic value serializer (sorted keys, circular-safe, pluggable) plus inline and file (.snap) matchers. Isomorphic core, with a node subpath for filesystem snapshots. Zero-dependency.

A fluent assertion library that runs anywhere — deep-equal, async resolves/rejects, toThrow, asymmetric matchers (any/objectContaining/…) and expect.extend custom matchers. Throws a descriptive error, so it plugs into any runner or the browser. Zero-dependency, isomorphic.
@lacspace/spySpies, stubs, mocks and deterministic fake timers for any test runner or the browser — record calls, program returns/throws/resolves with once-queues, spyOn with call-through, and tick a fake clock. Zero-dependency, isomorphic.
@lacspace/fixturesTyped, deterministic test-data factories — define a factory once, then build realistic objects with sequences, traits, associations and transient params. Seed it and the same data comes out every run. Zero-dependency, isomorphic.
