Hello all I am trying to do some jasmine/karma testing on a d3 application however I cannot get past this error: ReferenceError: Can't find variable: d3...

at C:/Users/test/Desktop/bob/angular-force-directed-graph/src/app/d3mapping.spec.js:9
ReferenceError: Can't find variable: d3
I know it has something to do with d3 being undefined until window.load but I am not sure how to properly define d3 and the methods it uses.

add d3 to your karma.conf.js files
if your project structure looks like this
|--app
| |--app.js
| |--...
|
|--test
| |--karma.conf.js
|
|--bower_components
you have to set the basePath to '../' because the karma.conf.js file lies inside the test folder but you want to address the files via 'app/app.js' or 'bower_components/...'
config.set({
basePath: '../' // dont forget the right basePath!
files:[
'path/to/d3'
],
...
})

This is my karma/karma.conf.js:

and this is my karma/tests/test_post.js:
describe('Controller: MainCtrl', function() {
beforeEach(module('PostPageApp'));
var ctrl;
beforeEach(inject(function($controller) {
ctrl = $controller('MainCtrl');
}));
it('Show have an add and logout function', function() {
expect(ctrl.add).toBeDefined();
});
});
and this is ../post.js:
angular.module("PostPageApp", ["BaseApp"])
.controller("MainCtrl", ["$http", "$window", "BaseService", function($http, $window, BaseService) {
var self = this;
self.add = function() {
BaseService.add.post(self.post, function() {
self.cerrorMessages = BaseService.cerrorMessages;
});
};
self.logoutUser = function() {
BaseService.logout();
};
}]);
Now, when I do karma start, it returns this:
04 01 2016 16:48:10.137:INFO [karma]: Karma v0.13.17 server started at http://localhost:9876/

Chromium 47.0.2526 (Ubuntu 0.0.0): Executed 0 of 0 ERROR (0.013 secs / 0 secs)
Any idea why it is executing 0 out of 0 and returning an error? I thought it would run
it('Show have an add and logout function', function() {
expect(ctrl.add).toBeDefined();
});
Please note that I am new to using Karma and Jasmine so I am still trying to get the hang of all of this.
Thanks in advance.
It's not running any tests because you aren't telling it to load any files into the browser. I think a lot of people use RequireJS for this, but unfortunately I am not familiar with it.
In karma.conf.js under the files: section:
List your JS dependencies (like JQuery or Angular).
List the files that you are testing next.
List the test specs themselves last.
For instance:
files: [
'angular.js',
'app.js',
'app.spec.js'
]
If you don't want certain files to be included then put them in the exclude section. Make sure the file paths are relative to where karma.conf.js is located.
I would suggest specifying a default path and a pattern at ./karma.conf.js:
// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: 'test/',
// list of files / patterns to load in the browser
files: [
{pattern: '**/*.js*', included: true}
],
It worked for me.
I am trying to run my application in Chrome using Karma. I configured karma.conf.js in such a way where I would expect the browser to run through all tests and then not exit: I have set this up with other projects and that is what occurs. However, on this project the browser always exits as soon as tests are finished and this prevents me from debugging.
Karma.config.js

I have the following test
require ('./src/gameService.js');
describe('gameService', function(){
describe('getState', function(){
it('should return the state of the box', function(){
gameService.gameState[1][2]=true;
expct(gameService.getState(1,2)).toBe(true);
})
})
})
And the following code in gameService.js
var gameState = []
...
this.getState = function(row, column){
return gameState[row][column];
}

I have an Angularjs project and I am using karma to run the tests. I am running into some problems with it, getting this error:
ReferenceError: Can't find variable: require

Reding into some forums, I was told to use karma browserify, but I am getting this error now:

I had a similar problem:
Warning: No provider for "framework:mocha"! (Resolving: framework:mocha)
This happened because I didn't include the plugin. Correct config:
...
singleRun: true,
plugins: ['karma-phantomjs-launcher', 'karma-mocha'], // here
frameworks: ['mocha'],
...
Also worth mentioning, you'll need to install the plugin:
npm install karma-mocha --save-dev
https://www.npmjs.com/package/karma-mocha
After further experimentation, looks like this is the error message delivered when you haven't included the plugin for a specified framework:
...
plugins: ['karma-phantomjs-launcher', 'karma-mocha', 'karma-chai'],
frameworks: ['mocha', 'chai'], // Will require the plugins above
...
I had a few problems with different versions of the libraries. But in the end, I got to make to work like this:

UPDATE
I recently updated all my libraries to the most recent version and I got this error again. I realized that I was missing the library browserify and watchify themselves. So I installed the two missing libraries and everything worked perfectly.
npm install --save-dev karma-browserify browserify watchify
In my javascript, document.getElementById always returns null in just case of run in karma. It's no problem when I load the html directly drop on browser. I think karma configuration is something wrong.

What is my mistake?
I find that karma could not include html files as default. To load html, html2js preprocessor is necessary. After convert html to js, karma can assign html to document object, but I don't know how to do that.
