code coverage report for multiple browsers in Karma

Question

How to create code coverage reports for all browsers present in Karma configuration file? My config.js looks like

module.exports = function (config) {
  config.set({
    frameworks: ['jasmine'],
    files: [...],
    browsers: ['IE', 'Firefox', 'Chrome'],
    reporters: ['progress', 'coverage'],
    preprocessors: { '*.js': ['coverage'] },
    coverageReporter: {
      type : 'html',
      dir : ...,
    },
    singleRun: true
     . . . .
});
};

All tests pass fine, but the report is generated only for the browser that finishes last. Json-formatted reports are generated normally for all browsers by the way.

I have

 npm of version 1.4.3 

and

node.js of version 0.10.26

installed on Win8 x64.

PS On Win7 x64 it seems to work: all reports are generated.

Answer 1

It happened to me too. Adding the next configuration will generate the coverage report for all browsers:

singleRun: true

Of course, the drawback is that tests will be ran only one time (the script will exit after that).
