Svelte HMR Spec
Test suite for Svelte 3 HMR.
The whole project is only the tests. And a cool cli to run them on various targets.
Install
git clone git@github.com:rixo/svelte-hmr-spec.gitcd svelte-hmr-specnpm installnpm install --global .cd appnpm installUsage
Quick start:
svhs --default # run tests on default (bundled) app svhs --help # learn more See inline help for an up to date description of available cli options:
svhs --helpTo run the tests on the default app (which should be last versions of svelte-loader, svelte, everything...):
svhs --defaultTo run the tests on a custom target (for example to test a svelte-loader during development):
svhs ./path-to-your-app --watchTest Apps
The tests expect a basic svelte + webpack application with HMR enabled. They also expect the app to contain a src/App.svelte file, and a src/main.js file that bootstraps this App component on the document's body.
This is actually the default structure of the webpack template app with some customization to allow for programmatic control of the webpack instance. In particular, the webpack dev server's config must be located in the webpack.config.js file (the contentBase option specifically).
Look at the provided default app for a precise reference of what is expected. My HMR demo app should also be kept in sync to be usable as a test target (so you can start from that if you want to create a custom test target app).
