TypeError: _enzyme2.default.configure is not a function

Question

So recently, I migrated from React 15.4.2 to React 16.0.0. Here are my current versions in project:

Along with React, I migrated to Enzyme 3.6.0 and started using enzyme-adapter-react, so in my entry file to tests (src/config.test.js) I did this:

import Enzyme from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

Enzyme.configure({ adapter: new Adapter() });

When I try to run tests with jest as I would usually, I get the error as in the title.

Also, if I try to use jest-enzyme and add this to my jest configuration:

"setupTestFrameworkScriptFile": "./node_modules/jest-enzyme/lib/index.js", 

I get another error :

TypeError: Super expression must either be null or a function, not undefined.

So I am kinda stuck, whatever I try, I cannot make my tests work. Any help is appreciated.

Answer 1

I was getting the same error. I found out my mistake was.

import shallow from 'enzyme';

I changed it to

import {shallow} from 'enzyme';

Answer 2

What helped me is the following: Rename alias from 'config' to something else e.g. 'my-config'. in moduleNameMapper:{ "my-config":"/src/config/test.js" ...}

and of course change imports in your js code. And should work.

It must have ben some name conflicts in enzyme or other dependencies.

Answer 3

Ran into this as well. In my case the problem was a bad setup that was redirecting any module whose name contained the substring configuration to my local environment-specific config.

In my specific case, with Jest, the fix was changing the jest moduleNameWrapper setting in package.json so that the key that redirected to my config was ^config$ instead of just config.
