Unit testing angular $log with jasmine

Question

I am running into some challenges unit testing $log.

I wanted to try a simple test that took the value I injected and tested. I am not hooking the spec up to a restful call yet. I am using angular mocks. Here are my before each statements. I have the module defined through angular mocks. Some of what I have been testing has came from this blog http://www.bradoncode.com/blog/2015/06/08/ngmock-fundamentals-log/ .

In my devDependencies

"angular": "^1.5.0",
"angular-mocks": "^1.5.0",

I am using gulp to set up the tests.

gulp.task('test:jasmine',  function (done) { // move to return async when execution metrics done

gulp.src('./Scripts/tests/modules/utility/services/ha-http.service.jasmine.test.js')
    .pipe(jasmine({
        verbose: true
    }))
    .on('error', gutil.log)
    .on('end', function () {
        console.log('jasmine end');
        done();
    });

});

So I know the versions of angular and mocks are matched up.

beforeEach(function () {

    angular.mock.module('ha.module.utility');

    angular.mock.inject(function ($httpBackend, haHttpService) {
        http = $httpBackend;
        service = haHttpService;
    });
});

beforeEach(inject(function (_$log_) {
    $log = _$log_;
}));

afterEach(function () {

    http.flush();
    http.verifyNoOutstandingExpectation();
    http.verifyNoOutstandingRequest();
});

The test itself is just making sure I have $log working.

it('should call logs', function () {
    $log.info('it worked');
    expect($log.info.logs).toContain(['it worked']);
});

However I am returning

ReferenceError: inject is not defined

************* Update ***********

I did set up $log in the mock module

angular.mock.module('ha.module.utility', function ($provide) {
            $provide.decorator('$log', function ($delegate) {
                return $delegate;
            });

        });



angular.mock.inject(function ($httpBackend, haHttpService, $log) {
            http = $httpBackend;
            service = haHttpService;
            console.log($log);
        });

I am getting the output I want in the console.log($log) when I run my gulp test. However, $log still returns

ReferenceError: $log is not defined 

in the spec.

ReferenceError: inject is not defined

means that inject global was not defined, literally. It is defined in angular-mocks.js on condition .

The problem is caused by testing rig and not the specs. angular-mocks.js may not be loaded, or it may be loaded before Jasmine.
