inside the frontend
folder, which is a React project, it works and the test pass. But when I run it in the root of my project, I get an error when running the same tests.Pablo Fernandez

FAIL frontend/src/App.test.tsx
● Test suite failed to run
Jest encountered an unexpected token
Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax.
Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.
By default "node_modules" folder is ignored by transformers.
Here's what you can do:
• If you are trying to use ECMAScript Modules, see <https://jestjs.io/docs/ecmascript-modules> for how to enable it.
• If you are trying to use TypeScript, see <https://jestjs.io/docs/getting-started#using-typescript>
• To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
• If you need a custom transformation specify a "transform" option in your config.
• If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.
You'll find more details and examples of these config options in the docs:
<https://jestjs.io/docs/configuration>
For information about custom transformations, see:

Add @babel/preset-react (<https://git.io/JfeDR>) to the 'presets' section of your Babel config to enable transformation.
If you want to leave it as-is, add @babel/plugin-syntax-jsx (<https://git.io/vb4yA>) to the 'plugins' section to enable parsing.
