…s resolve to the live instance
Test files were loaded with synchronous require(), which under tsx/cjs
created a second CommonJS copy of lib/* modules. A test's
`import { config } from "codeceptjs"` then resolved to a disconnected copy
whose module-level singletons were never populated (#5636).
Load test files through `await import()` instead — the same way the
container already loads helpers — so the whole run shares one ES module
graph and plain imports are honest. New lib/mocha/loadTests.js mirrors
Mocha's loadFiles (lazyLoadFiles + per-file pre-require/require/post-require)
to preserve teardown hooks, the gherkin .feature path, and the
dup/missing-Feature validation.
All synchronous mocha.loadFiles() sites converted: codecept.run(), rerun,
workers (parent grouping + worker threads), dry-run, and check.
TypeScript: tsx/cjs is a require hook and can no longer transpile test
files loaded via import(). requireModules() auto-maps tsx/cjs -> tsx/esm
with a deprecation notice; tsx/esm needs "type": "module" in package.json
(init now writes it, and an ERR_REQUIRE_CYCLE_MODULE guard points users to it).
BREAKING CHANGE: the programmatic Workers grouping API
(createGroupsOfTests, createGroupsOfSuites, addTestFiles, splitTestsByGroups)
is now async. TypeScript projects must set "type": "module" in package.json.
