Testem Multi Reporter

Helpful in running multiple reporters for the same test run. For example,
in CI, you can output a failure only, dot, or time reporter to the console, and
an xunit report to a file.

Installation

npm install --save-dev testem-multi-reporter

Usage

Create a testem.js config file that sets reporter to testem-multi-reporter,
and pass it the other reporters you want to use.

```
const MultiReporter = require('testem-multi-reporter');
const TimeReporter = require('testem-time-reporter');
const XunitReporter = require('testem/lib/reporters/xunit_reporter');

const reporters = [{
ReporterClass: TimeReporter,
args: [{ out: process.stdout }]
}, {
ReporterClass: XunitReporter,
args: [false, 'tests/xunit.xml', { get: () => false }]
}];
const multiReporter = new MultiReporter({ reporters });

module.exports = {
framework: 'qunit',
test_page: 'tests/index.html?hidepassed&coverage',
disable_watching: true,
launch_in_ci: [
'PhantomJS'
],
reporter: multiReporter
};
``

Run tests in an Ember CLI project, reporting only failures:

ember test --config-file ~/work/project/testem.js

Notes

This currently doesn't work with ember test --module some-module because Ember CLI
rewrites the testem.json file to accomplish this, and doesn't support the
testem.js` file.

See Ember CLI config rewriting
and testem.js parsing.
