How to run a unit test?

Question

JavaScript

Tested file code:

const Config = (stateHelperProvider, $urlRouterProvider, $locationProvider, $logProvider) => {
  /*@ngInject*/

  $logProvider.debugEnabled(true);
  $locationProvider.html5Mode(true);
  $urlRouterProvider.otherwise('/');
};

export default Config;

Calling the config in another file (at the entry point):

angular.module(appname, deps.concat(modules)).config(Config)

Test code:

import angular from 'angular';
import 'angular-mocks';

describe('Configuration of application', () => {
  let $locationProvider;

  beforeEach(() => {
    angular.mock.module((_$locationProvider_) => {
      $locationProvider = _$locationProvider_;
      spyOn($locationProvider, 'html5Mode').and.callThrough();
    });

    angular.mock.module('Simply');
    inject();
  });

  it('should set html5 mode', () => {
    expect($locationProvider.html5Mode).toHaveBeenCalledWith(true);
  });
});

Error code:

PhantomJS 2.1.1 (Mac OS X 0.0.0): Executed 0 of 1 SUCCESS (0 secs / 0 secs)
PhantomJS 2.1.1 (Mac OS X 0.0.0) Configuration of application should set html5 mode FAILED

  Expected spy html5Mode to have been called with [ true ] but it was never called.

Your error says that a call with the true parameter is expected, but the call does not occur.
So you need to call the function before expect.

describe('SomeBlock.init()', function () {
      beforeEach(function () {
        spyOn(SomeBlock, 'init').and.callThrough();
        spyOn(SomeBlock, 'addTab');
        SomeBlock.init();
      });
      it('SomeBlock.init() have been called', function () {
        expect(SomeBlock.init).toHaveBeenCalled();
      });
      it('SomeBlock.init() invoke addTab', function () {
        expect(SomeBlock.addTab).toHaveBeenCalled();
      });
      it('SomeBlock.init() invoke addTab gt 0 times', function () {
        expect(SomeBlock.addTab.calls.count()).toBeGreaterThan(0);
      });
    });
