With the latest CLI, inside angular.json “test”: { “builder”: “@angular-devkit/build-angular:karma”, “options”: { “main”: “src/test.ts”, “polyfills”: “src/polyfills.ts”, “tsConfig”: “src/tsconfig.spec.json”, “karmaConfig”: “./karma.conf.js”, “codeCoverageExclude”: [“src/testing/**/*”],
It does seem like this is a very general error, however in my case the problem was either that I didn’t run karma start from the correct folder, or that I didn’t restart it after changing the configuration. I’ll leave this question open and hopefully it can become a resource for others who experience this … Read more
That is because you need to configurate karma to load then serve them when requested 😉 In your karma.conf.js file you should already have defined files and/or patterns like : // list of files / patterns to load in the browser files : [ {pattern: ‘app/lib/angular.js’, watched: true, included: true, served: true}, {pattern: ‘app/lib/angular-*.js’, watched: … Read more

The reason was require function is not available to browser (it is undefined). To provide it to browser we can browserify the test js files before Karma runs test case in browser using … Read more
Try adding this code to your config. I had a similar issue once, and this workaround did the trick. app.config([‘$qProvider’, function ($qProvider) { $qProvider.errorOnUnhandledRejections(false); }]);
I’m using an angular setup with angular seed. I ended up solving this with straight .json fixture files and jasmine-jquery.js. Others had alluded to this answer, but it took me a while to get all the pieces in the right place. I hope this helps someone else. I have my json files in a folder … Read more
