Writing tests for client side code

The more code you have on the client side, the more it becomes a liability. For server side code, there's the well-entrenched unit tests, and for JavaScript, we have QUnit (https://qunitjs.com), which Odoo uses.

Getting ready

We'll add our tests to the addon developed in the previous recipes, so grab the code from the recipe Making RPC calls to the server and put it in a new module called ch15_r04.

How to do it...

We have to add our test file and make it known to the test mechanism in the appropriate template.

1. Add the static/test/ch15_r04.js file:

   odoo.define_section('ch15_r04', ['ch15_r04'], function (test, mock) {
       test('FieldMany2OneButtons', function(assert, ch15_r04)
       {

2. Create a minimal implementation of FieldManager:

           var fake_field_manager = {
               get_field_desc: function()
               {
                   return {
                       'relation': 'res.users',
                   ...
