Karma/Jasmine times out without running tests

Question

I'm trying to run Karma/Jasmine from Grunt on a project generated with http://newtriks.com/2013/12/31/automating-react-with-yeoman-and-grunt/

Karma launches PhantomJS (or Chrome) and, depending on singleRun, it either times out or just sits there and does nothing. I've tried changing captureTimeout and browserNoActivityTimeout based on reading solutions from people with similar problems, but it doesn't seem to work.

My relevant pacakge versions etc.:

• NodeJS: 0.10.25
• Karma: 0.12.16
• Webpack: 1.1.11
• webpack-dev-server: 1.4.1
• karma-jasmine: 0.1.5
• Linux: Ubuntu 14.04

I've found someone with the same problem on OS X:

I've tried updating all my dev dependencies to the latest versions but the problem still remains.

My console output is below. The webpack lines referring to bundle is now VALID/INVALID are worrying, but I can't find any info on what they mean. Here's my console output:

Here's my karma.conf.js file:

'use strict';  module.exports = function (config) { config.set({     basePath: '',     frameworks: ['jasmine'],     files: [         'test/helpers/**/*.js',         'test/spec/components/**/*.js'     ],     preprocessors: {         'test/spec/components/**/*.js': ['webpack']     },     webpack: {         cache: true,         module: {             loaders: [{                 test: /\.css$/,                 loader: 'style!css'             }, {                 test: /\.gif/,                 loader: 'url-loader?limit=10000&minetype=image/gif'             }, {                 test: /\.jpg/,                 loader: 'url-loader?limit=10000&minetype=image/jpg'             }, {                 test: /\.png/,                 loader: 'url-loader?limit=10000&minetype=image/png'             }, {                 test: /\.js$/,                 loader: 'jsx-loader'             }]         }     },     webpackServer: {         stats: {             colors: true         }     },     exclude: [],     port: 8080,     logLevel: config.LOG_DEBUG,     colors: true,     autoWatch: true,     // Start these browsers, currently available:     // - Chrome     // - ChromeCanary     // - Firefox     // - Opera     // - Safari (only Mac)     // - PhantomJS     // - IE (only Windows)     browsers: ['PhantomJS'],     reporters: ['progress'],     captureTimeout: 60000,     browserNoActivityTimeout: 60000,     singleRun: true }); };

I had the same problem. From a related GitHub Issue, I learned that you can extend the inactivity timeout.

Set this Karma config option in your gruntfile or karma config file:

browserNoActivityTimeout: 100000 

I set it to 100 seconds and my tests ran successfully. I don't know what's causing the delay.
