Splitting

ember exam --split=<num>

The split option allows you to specify the number of partitions greater than one to spread your tests across. Ember Exam will then proceed to run the first batch of tests.

ember exam --split=<num> --partition=<num>

The partition option allows you to specify which test group to run after using the split option. It is one-indexed, so if you specify a split of 3, the last group you could run is 3 as well. You can also run multiple partitions, e.g.:

ember exam --split=4 --partition=1 --partition=2

_Note: Ember Exam splits tests by modifying the ember-qunit's TestLoader to bucket each test file into a partition, where each partition has an even number of test files. This makes it possible to have unbalanced partitions. To run your tests with balanced partitions, consider using --load-balance. For more info, see Test Load Balancing.
