In my elixir application, I am implementing a cron job with this library GitHub - quantum-elixir/quantum-core: ⌚ Cron-like job scheduler for Elixir · GitHub. Below is my code for the same.

defp deps do
  [{:quantum, "~> 2.2"},
   {:timex, "~> 3.0"}]
end

defmodule MyApp.Scheduler do
  use Quantum.Scheduler,
    otp_app: :my_app
end

defmodule MyApp.Application do
  use Application

  def start(_type, _args) do
    import Supervisor.Spec, warn: false

    children = [
      # This is the new line
      worker(MyApp.Scheduler, [])
    ]

    opts = [strategy: :one_for_one, name: MyApp.Supervisor]
    Supervisor.start_link(children, opts)
  end
end

Then i am configuring cron job to print message like this after every 1 min

config :my_app, MyApp.Scheduler,
  jobs: [
    {"* * * * *", fn -> IO.puts("Hello QUANTUM!") end}
  ]

How can I test whether cron job is working or not in my local.I tried to use mix run but nothing seems to print the message even after the interval of 1 minute.
