Jest global variables with require modules - testing

Question

I'm working on some test for a very small vanilla js library, so I have this module
var otherModule = require('../module/mymodule');
var postscribe = require('postscribe');
var exports = module.exports = {};
var API_URL = URL;
exports.myFunction = function (arg1, arg2, arg3) {
if (arg1 && arg2) {
var myUrl = getApiUrl(arg1, arg2, arg3);
callSomeURL(myUrl);
}
}
function getApiUrl(arg1, arg2, arg3) {
var param1 = otherModule.getParams(arg1);
var param2 = otherModule.getOtherParams(arg1);
return `${API_URL}/v1/pixels/${arg1}/${arg2}${param1}${param2}`;
}
...
then I have otherModule module with my functions
var GLOBAL_VALUE = MY_VALUE;
var otherModule = {};
otherModule.getParams = function (arg1) {
return arg1 ? `&value=${arg1}` : '';
}
otherModule.getOtherParams = function (arg1) {
return GLOBAL_VALUE + arg1
}
module.exports = otherModule;
And my webpack configs
const { DefinePlugin } = require('webpack');
const { merge } = require('webpack-merge');
const common = require('./webpack.common.js');
const devConfig = require('./src/config/dev');
module.exports = () => {
var envConfig = devConfig;
return merge(common, {
mode: 'development',
devtool: 'inline-source-map',
plugins: [
new DefinePlugin({
__DEV__: true,
URL: JSON.stringify(envConfig.URL),
MY_VALUE: JSON.stringify(envConfig.VALUE)
})
]
})
}
my common is:
const path = require('path');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
module.exports = {
entry: './src/index.js',
plugins: [
new CleanWebpackPlugin()
],
output: {
filename: 'main.js',
path: path.resolve(__dirname, 'dist'),
},
};
And my jest.config
const config = require('./src/config/dev');
module.exports = {
globals: {
"MY_VALUE": config.VALUE,
"URL" : config.URL
}
}
my problem appears when I try to test exports.myFunction via rewire to have access to private function getApiUrl it seems that I can't access to the imported global values, like GLOBAL_VALUE
in my myOther, I keep getting ReferenceError: GLOBAL_VALUE is not defined, but when I test myOther module directly everything seems to work, can someone throw some light or resources on what I'm doing wrong?
