I'm new to Node and JS Testing. I have a web applications w/ Webpack as a bundler. I have some entry point JS's which are included into the page. The entry points are using module files like this:
export default function() {
...
}
Now I would like to Unit test this module. I have picked up Mocha but it is not critical to me. Could be Jest or anything else.
I wrote a very simple test.js like this. It it not doing anything but tests if the entire setup works:
import foo from '../js/someModuleOfMine'
const assert = require('assert')
describe('Test Suite', () => {
it('should at least run', () => {
assert.equal(true, true)
})
})
executing mocha from CLI gives me this error:
import foo from '../js/someModuleOfMine'
^^^^^^
SyntaxError: Cannot use import statement outside a module
Adhering to some advises I have tired to add "type": "module" to my package.json but it only changed error to something even more obscure:
Error: Not supported
I am definitely missing something obvious but I cannot comprehend what.
Not sure if it will help the OP, but I had the same problem and it was due to typescript. I solved in this way:
install ts-node:
npm install ts-node --save-dev
add the require line in the mocha config (I have it in the package.json, but one can also have it in the .mocharc.json file):
"mocha": {
"spec": "./**/*test.ts",
"ignore": "./node_modules/**",
"require": "ts-node/register/files",
"timeout": 20000
}
