I have karma-coverage (istanbul) setup & I love it, but it always fails coverage on this coffeescript line:
var bind = function(fn, me){ return function(){ return fn.apply(me, arguments); }; };
How can I configure istanbul+karma+coffeescript to skip this line in coverage?
Here is my karma.conf.js:
files: [
'components/**/*.coffee',
'spec/**/*.coffee'
],
# Which plugins to enable
plugins: [
"karma-coffee-preprocessor",
"karma-coverage"
],
reporters: ['coverage'],
preprocessors: {
'**/*.coffee': ['coffee'],
'components/**/*.coffee': ['coverage']
}

Is the best way to do that, simply to use the .only flag?
However, if I used describe.only(, I get
Uncaught TypeError: describe.only is not a function
So how can I run/debug only one test at a time?
Here is my karma.conf.js file:
const path = require('path');
module.exports = function (config) {
config.set({
// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: '',
// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter
frameworks: ['jasmine'],
// list of files / patterns to load in the browser
files: [
'./node_modules/angular/angular.js',
'./node_modules/angular-ui-router/release/angular-ui-router.js',
'./node_modules/angular-mocks/angular-mocks.js',
// './public/pages/admin/specs/abc.js'
'./public/dist/app-production.js',
// './public/**/*.spec.js'
],
// list of files to exclude
exclude: [],
// preprocess matching files before serving them to the browser
// available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
preprocessors: {},

logLevel: config['LOG_WARN'],
// enable / disable watching file and executing tests whenever any file changes
autoWatch: false,

The solution I have for the moment works quite well, all I do is change one line of our karma.conf.js file, like so:
before:
files: [
'./node_modules/angular/angular.js',
'./node_modules/angular-ui-router/release/angular-ui-router.js',
'./node_modules/angular-mocks/angular-mocks.js',
'./public/dist/app-production.js',
'./public/**/*.spec.js'
],
after:
files: [
'./node_modules/angular/angular.js',
'./node_modules/angular-ui-router/release/angular-ui-router.js',
'./node_modules/angular-mocks/angular-mocks.js',
'./public/dist/app-production.js',
process.env.KARMA_TEST_PATH || './public/**/*.spec.js'
],
now your just run karma like so:
KARMA_TEST_PATH=public/pages/x/specs/foo.spec.js karma start
and it will run that single test instead of all your specs.
I try to set up rollup with karma and babel for test.
I face two problems.
First, it cause error Uncaught TypeError about default.
Uncaught TypeError: Cannot use 'in' operator to search for 'default' in undefined
Second, it doesn't find external dependency.
Treating 'chai' as external dependency
What's wrong in my settings?

I am trying to debug single test using Karma and WebStorm.

when I do not use coverage reporter and run karma.config with --

changing it into fit in unit test.

I am trying to get my project working with Karma and SystemJS. I am using the karma-systemjs plugin with karma.

I fixed this by moving the bootstrap code out of the config code. Apparently when using the karma-systemjs plugin System.import is not available yet when this is called (although it is at normal runtime).
What I did: I moved the bootstrap code (i.e. Promise.all([....) into into a separate file called bootstrap.js (name is not important) and then in my index.html I added them in this order:
Also from this link (the karma system js plugin author says): https://github.com/rolaveric/karma-systemjs/issues/71
I see the problem. It's because you've got your bootstrapping code
(eg. System.import() calls) inside your SystemJS config file -
system.conf.js karma-systemjs expects just a simple System.config()
call that it can then intercept to find out where your transpiler and
polyfills are. It does this by evaluating your config file with a fake
System object which simply records whatever is passed to
System.config(). This fake object has no System.import() method, which
causes your error.
I'd recommend moving your bootstrapping code into a separate file (I
personally put it in a script tag with my HTML). Otherwise you'll run
into similar problems if you try to use systemjs-builder, and you
probably don't want angular.bootstrap() to be called at the start of
your unit tests.
I have included the source files in the files & preprocessors section of my karma conf file. The tests run fine and the junit xml report shows the data. The html coverage just show 100% without any data. I have the similar structure for another project which is working fine but not this one. Not sure if i am missing something. Might be a very minor or silly thing i have missed.
karma.conf.js:
module.exports = function (config) {
config.set({
basePath: '../../',
frameworks: [
'jasmine'
],
// list of files / patterns to load in the browser
files: [
'app/js/**/*.js',
'test/spec/**/*.js'
],
preprocessors: {
'app/js/**/*.js': ['coverage']
},
exclude: [],
reporters: [ 'progress', 'junit', 'coverage' ],
coverageReporter: {
type: 'html',
dir: 'test/reports/unit/coverage'
},
junitReporter: {
outputFile: 'test/reports/unit/junit/junit.xml',
suite: 'unit'
},
port: 9876,
runnerPort: 9100,
colors: true,
logLevel: config.LOG_DEBUG,
autoWatch: false,
browsers: [ 'Chrome' ],
captureTimeout: 60000,
singleRun: true
});
};
my karma conf file is in test -> spec -> conf
and source files are in app -> js -> controllers/directives/services
the debug log shows its loading all the files in preprocessors but the report does not show any data "No data to display".
Use the following process:
Append the basepath to the preprocessor path:
../../app/js/**/*.js': ['coverage']
Restart karma
