javascript - Ajv not defined in Jest test

Question

I want to test my class with jest. This class is importing ajv.js 6.12.2 and the test fails on that. So what i basicly did is:

1. Add export default Ajv statement to the end of the ajv.js
2. Import ajv.js with import Ajv from './lib/ajv.js'
3. Add "transform": {"^.+\.jsx?$": "babel-jest"} to package.json
4. Created babel.json and insert { "presets": ["@babel/preset-env"], "plugins": ["@babel/plugin-proposal-class-properties"] }

When I run the test with npm test I get the following error:

ReferenceError: Ajv is not defined

    > 4 | export default Ajv;`

When I run the script in browser Ajv could be used normally. Can anybody give me a hint what to do?
