  • Testing Svelte components with Jest and Vite
    8 projects | | 18 Nov 2021
    We need to configure Jest to transform our files. We must explicitly set our test environment to jsdom, which we are using through Jest. Since v27 Jest's default test environment is node. I will put the configuration in a specific Jest configuration file called jest.config.json in the project root folder. If you create a configuration file called jest.config.js, Vite will complain as it expects only ESM JavaScript by default. Vite will recommend that you rename it to a ".cjs" file if you want to do it that way. You can look at the different ways to configure Jest if you are unsure about the file conventions. If you're using TypeScript, you need to configure svelte-preprocess and ts-jest also, see the svelte-jester docs for how to do that.
