Firework Interview Assignment

Write tests to assert ExScheduler.Worker periodic behaviour in test/ex_scheduler/worker_test.exs.

ExScheduler

Cron-like job scheduler in few lines of elixir code.
Inspired in this answer by José Valim.
Added cron syntax, with extended support for seconds.

Installation

def deps do
  [
    {:ex_scheduler, "~> 0.1.0"}
  ]
end

Add ExScheduler.Worker to your supervision tree:

  children = [
    {ExScheduler.Worker, jobs}
  ]

And the jobs configuration:

  defp jobs() do
    [
      %{cron: "* * * * * *", module: Example, function: :hello, args: ["world"]},
      %{cron: "* * * * * *", module: PerformExample},
    ]
  end

If using Phoenix Framework, you should pull this configuration from config.exs.

Important:

• When the function is omitted, perform/0 function is called.
• When args are ommited, the function is called with no attributes.
• Cron expressions are evaluated over UTC time.
