Gate: pin the test universe - #10
Conversation

📝 WalkthroughWalkthroughDELIVERY.md adds a “Pin the test universe” gate. It requires project-scoped test discovery, flags unexplained test-count changes, and records an rnxORM incident involving an abandoned worktree. ChangesTest universe gate
Estimated code review effort: 1 (Trivial) | ~2 minutes Merge Risk: 🔵 Low · up to The change narrows test collection to the intended project roots, but the documented denylist can still miss new non-project worktrees, and related identity and configuration claims should be corrected. These are bounded merge-readiness risks rather than release-blocking failures, so the PR is mergeable with explicit owner follow-up. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 317-318: Correct the Jest glob description in the “Caught”
documentation: do not claim Jest defaults to **/test/**, and cite the rnxORM
configuration if it defines that pattern; otherwise describe it as the
repository’s configured glob. Preserve the worktree discovery details while
updating only the inaccurate default-glob attribution.
- Around line 312-315: Update the test-runner guidance to require explicit Jest
roots covering only the project’s own test directories, while retaining ignore
patterns as defense in depth for vendored checkouts, worktrees, and tool scratch
space. Replace the inaccurate reference to Jest’s default test glob with the
actual configured collection behavior, and treat any unexplained increase in
collected-test counts as a finding rather than a bonus.

Jest configuration documentation roots testMatch testPathIgnorePatterns default testMatch
💡 Result:
In Jest configuration, the roots, testMatch, and testPathIgnorePatterns options control where Jest looks for tests and which files it executes. roots The roots option defines a list of paths to directories that Jest should use to search for files [1][2]. While rootDir is primarily used as a token for other configuration options, roots is used by Jest internals to locate test files, source files, and manual mocks (such as mocks folders) [1][3][2]. The default value is [""] [1][4]. testMatch The testMatch option defines the glob patterns Jest uses to detect test files [5][3]. By default, it looks for the following patterns [4]: - /tests//.?([mc])[jt]s?(x) - /?(.)+(spec|test).?([mc])[jt]s?(x) This means it automatically detects files inside tests folders, as well as files with a.test,.spec,.js,.jsx,.ts, or.tsx suffix (including those using mjs, cjs, mts, or cts extensions) [5][4]. testPathIgnorePatterns The testPathIgnorePatterns option is an array of regexp pattern strings that are matched against all test paths before execution; if a path matches any pattern, the test is skipped [5][3][2]. The default value is ["/node_modules/"] [5][3][4]. When configuring these patterns, it is recommended to use the string token to include the path to your project's root directory, preventing issues where different environments might have different root paths (e.g., ["/build/", "/node_modules/"]) [5][3].

Define the test universe with explicit Jest roots.
testPathIgnorePatterns only excludes paths that match known patterns. Require explicit project roots and document ignore patterns as defense in depth. Replace “Jest's default **/test/** glob” with the actual configuration, because Jest's documented defaults use __tests__ and *.test/*.spec patterns.

Jest configuration default testMatch patterns **/test/** rnxORM BaryoDev/rnxORM Jest config
💡 Result:
Jest's default testMatch configuration is designed to automatically discover test files throughout a project [1][2]. The default patterns are: [ "/tests//.?([mc])[jt]s?(x)", "/?(.)+(spec|test).?([mc])[jt]s?(x)" ] [3][1][2] These patterns instruct Jest to look for: 1. Any files inside folders named tests with extensions like.js,.jsx,.ts,.tsx,.cjs,.mjs,.cts, or.mts [1][2]. 2. Any files that end with.test or.spec (e.g., component.test.ts, util.spec.js) using the same set of supported extensions [1][2]. Regarding the BaryoDev/rnxORM project, official repository documentation and commit history indicate that the project uses standard testing practices [4]. The codebase relies on a structured test directory that organizes tests into subfolders such as test/unit/ and test/integration/ [5][6][4]. Because these files follow the standard naming conventions (e.g., ActualApi.test.ts, ChangeTracker.test.ts), they are automatically detected by Jest's default configuration without requiring custom testMatch patterns [5][6][4][3]. If you find that your project is not picking up these files, ensure your Jest configuration does not define testRegex, as testMatch and testRegex cannot be used simultaneously [1][2][7].

Correct the Jest default-glob claim.
Jest's default testMatch patterns are **/__tests__/**/*.?([mc])[jt]s?(x) and **/?(*.)+(spec|test).?([mc])[jt]s?(x), not **/test/**. The .github repository contains no configuration or command that sets this glob. Cite the rnxORM configuration if it exists; otherwise, replace “Jest's default” with “the repository's configured glob”.

From today's rnxORM audit session: Jest's default glob was collecting an abandoned worktree under .claude/, reporting 605 tests where the project had 286 — 6 phantom failures from dead code, and green passes proving nothing about main. Caught by a human reconciling the count, not by a mechanism; the mechanism (pinned collection roots, committed to the repo) is the gate. Details in the section.
