Angular2 testing: Error when trying to use: @angular/platform-browser/testing/browser_util

I'm trying to use @angular/platform-browser/testing/browser_util when running an angular2 test. Angular2 core version is 2.3.0. I'm getting the following 404 error:

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.
