Ember Try & CI Integration

Integrating ember-exam with ember-try is remarkably easy. Define a command in your ember-try.js config that leverages the exam command:

// config/ember-try.js
module.exports = {
  command: 'ember exam --split 3 --parallel',
  // ...
};

Using environmental variables gives you flexibility in how you run your tests. For instance, you could distribute your tests across processes instead of parallelizing them by specifying a PARTITION variable in your process environment and then consuming it like so:

module.exports = {
  command: 'ember exam --split 20 --partition ' + process.env.PARTITION,
  // ...
};

If you are working with Travis CI then you can also easily set up seeded-random runs based on PR numbers. Similar to the following:

const command = ['ember', 'exam', '--random'];
const pr = process.env.TRAVIS_PULL_REQUEST;

if (pr) {
  command.push(pr);
}

module.exports = {
  command: command.join(' '),
  // ...
};

You can refer to Travis' default environment variables to see what else you could possibly leverage for your test setup.
