Jobs
The fundamental execution unit in Maelstrom is a job. A job is a program that is run in its own container, either locally or on a cluster. Jobs are intended to be programs that terminate on their own after doing some fixed amount of work. They aren't intended to be interactive or to run indefinitely. However, Maelstrom does provide a mechanism for running a job interactively for troubleshooting purposes.
Test runners will usually translate each test case into its own, standalone job. So, in the context of a test runner, we use the term "job" and "test" interchangeably.
