Enzyme Internal Error: Enzyme expects an adapter to be configured, but found none. #131
Closed
Description
Following the documentation of this tutorial the Hello.test.tsx files errors like the title above.
From what I read online, the packages @types/enzyme
and react-addons-test-utils
would suffice the need to configure an adapter manually on a testsSetup.js
That didn't work.
I took the second route and wrote a testsSetup.js inside my src
setupTests.js (should this be .ts
, .tsx
?, either way it did not work)
import * as enzyme from 'enzyme';
import * as Adapter from 'enzyme-adapter-react-16';
enzyme.configure({ adapter: new Adapter() });
Hello.test.tsx
import * as React from 'react';
import * as enzyme from 'enzyme';
import Hello from './Hello';
it('renders the correct text when no enthusiasm level is given', () => {
const hello = enzyme.shallow(<Hello name='Daniel' />);
expect(hello.find(".greeting").text()).toEqual('Hello Daniel!')
});

Another source suggested adding extra config to jest on package.json such as
........
"jest": {
"setupTestFrameworkScriptFile": "<rootDir>/src/setupTests.js"
}
However that errors as:
These options in your package.json Jest configuration are not currently supported by Create React App:
• setupTestFrameworkScriptFile
Further...
A fresh clone of this repo errors out not running any test suites and complaining about cheerio names.
How can we get the Enzyme Adapter to work with the current project setup on .tsx
files?
