I've been struggling to get karma coverage to work for the past couple of days, but all I keep seeing is a blank empty page like this: https://i.sstatic.net/3Fr6I.png
Check out my configuration:
var path = require('path');
var webpackConfig = require('./webpack.common');
module.exports = function (config) {
var _config = {
basePath: '',
frameworks: ['jasmine'],
files: [
{ pattern: './karma-shim.js', watched: false }
],
exclude: [],
preprocessors: {
'./karma-shim.js': ['webpack', 'sourcemap', 'coverage']
},
client: {
captureConsole: false
},
webpack: webpackConfig,
webpackMiddleware: {
stats: 'errors-only'
},
coverageReporter: {
dir: 'coverage/',
reporters: [{
type: 'json',
dir: 'coverage',
subdir: 'json',
file: 'coverage-final.json'
}]
},
remapIstanbulReporter: {
src: 'coverage/json/coverage-final.json',
reports: {
lcovonly: 'coverage/json/lcov.info',
html: 'coverage/html',
'text': null
},
timeoutNotCreated: 1000, // default value
timeoutNoMoreFiles: 1000 // default value
},
webpackServer: {
noInfo: true // please don't spam the console when running in karma!
},
reporters: ["mocha", "coverage", "karma-remap-istanbul"],
port: 9876,
colors: true,
logLevel: config.LOG_ERROR,
autoWatch: false,
browsers: ['PhantomJS'], // you can also use Chrome
singleRun: true
};
config.set(_config);
};
Here's the content of my karma-shim.js file:
Error.stackTraceLimit = Infinity;
require('es6-shim');
require('reflect-metadata');
require('ts-helpers');
require('zone.js/dist/zone');
require('zone.js/dist/long-stack-trace-zone');
require('zone.js/dist/jasmine-patch');
require('zone.js/dist/async-test');
require('zone.js/dist/fake-async-test');
var appContext = require.context('./app', true, /\.spec\.ts/);
appContext.keys().forEach(appContext);
var testing = require('@angular/core/testing');
var browser = require('@angular/platform-browser-dynamic/testing');
testing.setBaseTestProviders(browser.TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS, browser.TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);
This is how my folder structure looks: https://i.sstatic.net/1Eb2s.png
If you have any insights on what might be causing this issue, your help would be greatly appreciated.
Thank you!
