What am I missing here ?

Answer 1

Your issue is how you have the testing bundle configured in your system.config.js

This:

@angular/platform-browser/bundles/platform-browser-testing.umd.js/browser_util

Means it's looking for the browser_util under the "platform-browser-testing.umd.js" which is a file, not a directory.

Your system.config.js should be configured for this bundle:

@angular/platform-browser/bundles/platform-browser-testing.

Update 1:

Here is your properly configured System.config.js. The difference is that when it doesn't need to be bundled, it uses the individual files. In particular these lines:

// Individual files (~300 requests):
    function packIndex(pkgName) {
        packages['@angular/' + pkgName] = {main: 'index.js', defaultExtension: 'js'};
    }

    // Bundled (~40 requests):
    function packUmd(pkgName) {
        packages['@angular/' + pkgName + '/bundles/'] = {main: pkgName + '.umd.js', defaultExtension: 'js'};
    };

    // Most environments should use UMD; some (Karma) need the individual index files
    var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;

The whole file:

(function (global) {
    // map tells the System loader where to look for things
    var map = {
        'app': 'app',
        '@angular': 'node_modules/@angular',
        '@angular/common': 'node_modules/@angular/common',
        '@angular/compiler': 'node_modules/@angular/compiler',
        '@angular/platform-browser': 'node_modules/@angular/platform-browser',
        '@angular/platform-browser-dynamic': 'node_modules/@angular/platform-browser-dynamic',
        '@angular/http': 'node_modules/@angular/http',
        '@angular/router': 'node_modules/@angular/router',
        '@angular/forms': 'node_modules/@angular/forms',
        'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
        'rxjs': 'node_modules/rxjs',
    };

    // packages tells the System loader how to load when no filename and/or no extension
    var packages = {
        'app': {main: 'main.js', defaultExtension: 'js'},
        'rxjs': {defaultExtension: 'js'},
        'angular2-in-memory-web-api': {main: 'index.js', defaultExtension: 'js'},
    };

    var ngPackageNames = [
        'common',
        'compiler',
        'core',
        'http',
        'platform-browser',
        'platform-browser-dynamic',
        'router',
        'router-deprecated',
        'upgrade'
    ];

    // Individual files (~300 requests):
    function packIndex(pkgName) {
        packages['@angular/' + pkgName] = {main: 'index.js', defaultExtension: 'js'};
    }

    // Bundled (~40 requests):
    function packUmd(pkgName) {
        packages['@angular/' + pkgName + '/bundles/'] = {main: pkgName + '.umd.js', defaultExtension: 'js'};
    };

    // Most environments should use UMD; some (Karma) need the individual index files
    var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;

    // Add package entries for angular packages
    ngPackageNames.forEach(setPackageConfig);

    var config = {
        map: map,
        packages: packages,
        meta: meta
    };

    System.config(config);
})
(this);

Update 2:

1. "The difference is that when it doesn't need to be bundled, it uses the individual files" ... Can you further explain this ? What is a bundle?

A bundle is the JavaScript created from all combined JavaScript files in the package. If you look in the "node_modules\@angular\platform-browser\bundles" directory you sill see files ending with ".umd" as in "platform-browser.umd.js." Those files are generally used when you build your application for production. However (for a reason unknown to me), Karma cannot use the bundled files and needs the individual files as in "node_modules\@angular\platform-browser\testing\browser_util.js."

2. How does System.packageWithIndex gets updated?

I have no idea. I see everyone using it, but when I output it on the console it's undefined. After looking for it, I can't find it even in the source of the SystemJS library. I'll have to post a question on here and see if everyone knows, or if it's something that just got copied/pasted and nobody bothered to ask why.

In the meantime I looked at the Karma config for the official Angular starter and saw that they configure SystemJS separately for Karma, and import the testing modules separately. I recommend you look at that and do the same thing. https://github.com/angular/quickstart/blob/master/karma-test-shim.js

3. I see you are updating packages variable. Can you give an example to a path that has been set in this var?

The idea was that the variable "setPackageConfig" was set to either the "packIndex" or "packUmd" function and that is used as a callback to build the packages either from the bundle or the individual files.

I am leaving this here as reference but check out the karma config in https://github.com/angular/quickstart/blob/master/karma-test-shim.js and disregard the previous systemjs configuration.

Answer 2

While the answer above will get your code working, it's worth noting that the reason you see the error for this file and no other is that the Angular team have not included browser_util as part of the public API, and thus it is not exported in the UMD bundles that you are loading via SystemJS.

Using the config provided in the other answer you can get around this by having SystemJS load the individual file itself if it does not resolve the import to a UMD bundle (although it will be loaded with ES6 import synax intact).

The fact that dispatchEvent is a private API even though it is referred to in many testing tutorials has been noted by the Angular team in this GitHub issue.
