How to query by text string which contains html tags using React Testing Library?
Reactjs Current Working Solution Using this html: Name: Bob (special guest) I can use the React Testing Library getByTestId method to find the textContent: expect(getByTestId('foo').textContent).toEqual('Name: Bob (special guest)') Is there a better way? I would like to simply use this html: Name: Bob (special guest) And use React Testing Library's getByText method like this: expect(getByText('Name: Bob (special guest)')).toBeTruthy() But this does not work. So, the question… Is there a simpler way to use React Testing Library to find strings of text content with the tags striped out?

Unit Testing Expo Apps With Jest
console.error 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: https://jestjs.io/docs/code-transformation
