// Shared harness for testing the custom ESLint rules in eslint-plugins/.
|
|
//
|
|
// Two strategies, picked per rule in the test files:
|
|
// - RuleTester (eslint) — pure string cases, no filesystem. Best fit for the
|
|
// design-tokens rules that only inspect the postcss AST of Svelte `<style>`.
|
|
// - Linter API + fixtures — needed when a rule reads real files. The isolation
|
|
// rule resolves imports via fs (targets must exist on disk) and
|
|
// no-undefined-in-svelte reads <cwd>/src/app.css for the token dictionary.
|
|
// `verifyInFixtures` runs a rule with cwd fixed to `__fixtures__/`, so both
|
|
// work without touching process.cwd() or the real src/ tree.
