Tests

You did a great job with tests and you wrote enough tests to cover all the pure logic functions you have but there's a problem encountered with the imports and the export
https://github.com/GSG-G10/DevMonkeys-Ecommerce/blob/0b47b4ec1f48ee4bd3270d6c49b4f9ce9c2a47b9/test/test.js#L1

There's some repeated functions , it should be like this and `filterByCategory` isn't exported in `logic.js`
```js
const {filterByCategory , FilterByPrice ,search,addItem , deleteItem, editItem, sumCart} = require ("../js/logic.js");
```

```js
if (typeof module !== 'undefined') {
module.exports = {
filterByCategory, addItem, search, editItem, sumCart, FilterByPrice, deleteItem
}
}
```
