Use for ANY work touching the `handsontable/` core package: fixing bugs, adding features, modifying TypeScript types, removing as-casts, writing or debugging plugins, editors, renderers, validators, cell types, hooks, shortcuts, selection, helpers, index translations, or i18n. Also use for how-to questions about core internals (plugin lifecycle, coordinate systems, hook registration, TypeScript conventions). Triggers on file paths under `handsontable/src/` (excluding `3rdparty/walkontable/` which has its own skill), or when the user describes a symptom in the core grid without naming a file. This is the primary entry point for all core Handsontable development — when in doubt, load it.
Use when writing or modifying Jasmine/Puppeteer E2E tests (*.spec.js) for Handsontable, or when a bug fix or feature change needs E2E test coverage. Covers standard boilerplate, async/await rules, global helpers, event simulation, plugin lifecycle patterns, and writing theme-agnostic assertions that pass under all themes without branching on theme name.
Use when writing or modifying Jest unit tests (*.unit.js) or TypeScript type tests (*.types.ts) for Handsontable core, plugins, or utilities, or when a bug fix or internal refactor needs unit or type test coverage - covers Jest setup, test location conventions, mocking patterns, module aliases, type test patterns (no declare, real assignments, ESM + UMD patterns), and when to choose unit tests over E2E tests

Walkontable has its own dedicated test runner. Do NOT run Walkontable tests through the main test:e2e or test:unit commands -- they will not be picked up.
npm run test:walkontable --prefix handsontablesrc/3rdparty/walkontable/test/The directory contains two sub-pipelines:
test/spec/ -- E2E-style specs (Jasmine + Puppeteer, same as main E2E but with a separate Rspack config and bootstrap)test/unit/ -- Unit-style specs for calculators, filters, renderers, and utilitiesThe same async/await rules that apply to main E2E tests apply here. All it() callbacks that call rendering APIs must be async, and those API calls must be await-ed.
Tests are organized by subsystem: overlay/, scroll/, selection/, renderer/, table/, viewport.spec.js, etc. Place new tests in the directory that matches the subsystem you are modifying.
forEach loops to populate data arrays -- never arr.push(...largeArray).test:e2e -- they have their own command and will not execute.spec/ and unit/ sub-pipelines still pass.rowHeightsUniform/columnWidthsUniform) in a bare Walkontable spec and then asserting scrollbar-dependent row/column counts: the bare harness overflows content without rendering a real scrollbar, while the single-pass layout snapshot predicts one — so predicted and measured diverge there. Assert the snapshot booleans directly, or use a fixture that renders a real scrollbar; don't compare snapshot-predicted scrollbars/counts against the bare DOM.
