Call external function in unit test

Question

I'm trying to learn qunit test; I'm an OpenUi5 developer and I use Webstorm IDE every day. Webstorm allows me to config a Karma run configuration. I have created a simple karma configuration file and I have wrotten a test file test1.js:

test("Test function sum()",
  function() {
    ok(sum(0, 0) == 0, "the sum of 0 with 0 is 0");
    ok(sum(2, 0) == 2, "the sum of 2 with 0 is 2");
    ok(sum(2, 1) == 3, "the sum of 2 with 1 is 3");
    ok(sum(2, -1) == 1, "the sum of 2 with -1 is 1");
    ok(sum(-2, 1) == -1, "the sum of -2 with 1 is -1");
  });


function sum(a, b) {
  return a + b;
};

Good! sum function is inside the same file. But now I want start to test functions in my js folder of the project (the unit test are in test-resources folder); for example in js/util.js I have getShortIdGrid function:

//util.js file
jQuery.sap.declare("ui5bp.control");

ui5bp.control = {
  ...
  getShortIdGrid: function(sFromId) {
      if (sFromId.lastIndexOf("_") < 0)
        return sFromId;
      else
        return sFromId.substring(0, sFromId.lastIndexOf("_"));
  },
  ...
}

and this is my the my test:

test("test getShortIdGrid",
    function () {
        equal( ui5bp.control.getShortIdGrid("shortId_123"), "shortId" ,"ShortIdGrid of 'shortId_123' is 'shortId'" );
    });

How can I call ui5bp.controlgetShortIdGrid in my test?

Karma console show me ReferenceError: ui5bp is not defined.

After loading properly the util.js file, how can I mange the declaration jQuery.sap.declare("ui5bp.control"); on the top? I would like test my simple function without reloat the full library!

You need to make sure that unit.js is included in karma configuration file, files property, to make it available to karma. For example, if you have your unit.js located in /src folder, whereas your specs are in /tests, it would look as follows:

module.exports = function (config) {
    config.set({

        // base path, that will be used to resolve files and exclude
        basePath: '',
        frameworks: ['qunit'],
        files: [
            'tests/**/*.js',
            'src/*.js'
        ],
        exclude: [],
...

That's enough to get ui5bp resolved
