dainte

• Purpose: Dainte is a testing library designed for Svelte components, inspired by Enzyme. It provides tools for testing both runtime and server-side rendering (SSR) simultaneously with minimal configuration.

• Key Features:

  • Test Svelte runtime and SSR together
  • Zero-config compatibility with Jest
  • Low-level compile options to ensure tests match production behavior
  • Component state introspection

• Target Audience: Developers working with Svelte who need a streamlined way to test components in both DOM and SSR environments.

• Core Functions:

  • dainte.compile: Compiles Svelte components from source files with customizable options like dev, immutable, and hydratable. Supports Svelte's compile options fa-solid fa-up-right-from-square.
  • dainte.mount: Mounts a component in a JSDom environment, allowing DOM interactions and state updates. Includes aliases for easy access to the component instance and DOM elements.
  • dainte.render: Renders components to HTML for SSR testing, with options like preserveWhitespace and preserveComments.
  • instance.inspect: Provides a snapshot of top-level variables and imports when compiled with inspect: true, useful for debugging state.

• Framework Support: Primarily focused on Svelte, with deep integration for both DOM and SSR testing.

• Example Use Case:

  import { mount } from 'dainte';
  const { app, document } = await mount('./App.svelte');
  app.$set({ answer: 42 });
  expect(document.querySelector('#answer').textContent).toBe('42');
