test: cover the classifier, the discovery walk and the launcher - #1
Conversation
Every test lived in the scanner, which left the parts most likely to be wrong unguarded: the rules deciding whether a specifier needs a package installed, the walk that finds the packages to begin with, and the packageExtensions block users paste into their configuration. The classifier rules are the ones that were tuned by reading output against a single corpus — builtins, subpaths, protocol URLs, a scope with no package after it, and @types matched in both directions, since @types/estree satisfies a bare estree import ambiently while a /// <reference types="node" /> is satisfied by either spelling. Discovery is covered by a fixture in the shape a global virtual store produces, where node_modules holds links and each store entry holds a package beside the dependencies it may reach. That is the layout whose assumptions broke once already, and it also pins two behaviours worth keeping: the walk crosses from the project into every entry, and declarations vendored under a package's own node_modules are not mistaken for its sources. The emitted block is checked as text and parsed as YAML, because a quoting slip would hand someone a file their package manager cannot read. The launcher had no automated test at all. Its target naming is now shared with the generator rather than written twice, and one test walks every platform, architecture and libc it can name to assert a package is published for each — the failure that would otherwise only appear on a user's machine.

If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

One test fixture could be strengthened to cover a declared dependency path, but this is a bounded follow-up rather than a merge blocker. Sequence Diagram(s)sequenceDiagram

The test asserting that a declared import goes unreported was checking nothing of the sort: the package it scanned declared no dependency and imported no module, so it only proved that a package with no imports has no findings. It now declares a dependency and imports it, and switching that dependency to a devDependency makes the test fail, which is the property it was supposed to have all along. The launcher tests read package.json instead of importing it. Import attributes are newer than the runtime floor the package advertises, so the suite could fail to parse before running on a runtime the package claims to support. That floor is now one that exists in the wild — Node 18 has been out of support for over a year, and nothing here needs to reach back that far — and CI runs the launcher tests on both the floor and the current release rather than on whatever the runner happens to ship.
