+Each sub-directory is a mini webpack project with a Jasmine test suite.

-Tests prefixed with a TypeScript version (e.g. `2.0.3_es2016`) are skipped when the installed TypeScript is older than that prefix.
+A test's `test.json` sets when it runs (see `test/testConfig.js`, shared with the comparison tests): `"minWebpack": 5` skips it on older webpack, and `"skip": "<reason>"` always skips it. Shared test dependencies (`jasmine`, `@types/jasmine`, Babel 7, `babel-loader` 8) live in the root `package.json`; a test only has its own `package.json` for anything else.
 
 Every `webpack.config.js` in this pack must include this alias so the local ts-loader is resolved:
