Returns a specification to start this module under a supervisor.

See Supervisor.

@spec reset() :: :ok

Reset all sequences so that the next sequence starts from 0

Example

ExMachina.Sequence.next("joe") # "joe0"
ExMachina.Sequence.next("joe") # "joe1"

ExMachina.Sequence.reset()

ExMachina.Sequence.next("joe") # resets so the return value is "joe0"

You can use list as well

ExMachina.Sequence.next("alphabet_sequence", ["A", "B"]) # "A"
ExMachina.Sequence.next("alphabet_sequence", ["A", "B"]) # "B"

ExMachina.Sequence.reset()

ExMachina.Sequence.next("alphabet_sequence", ["A", "B"]) # resets so the return value is "A"

If you want to reset sequences at the beginning of every test, put it in a setup block in your test.

setup do
  ExMachina.Sequence.reset()
end

@spec reset(any()) :: :ok

Reset specific sequences so long as they already exist. The sequences specified will be reset to 0, while others will remain at their current index.

You can reset a single sequence,

Example

ExMachina.Sequence.next(:alphabet, ["A", "B", "C"]) # "A"
ExMachina.Sequence.next(:alphabet, ["A", "B", "C"]) # "B"

ExMachina.Sequence.reset(:alphabet)

ExMachina.Sequence.next(:alphabet, ["A", "B", "C"]) # "A"

And you can also reset multiple sequences at once,

Example

ExMachina.Sequence.next(:numeric, [1, 2, 3]) # 1
ExMachina.Sequence.next(:numeric, [1, 2, 3]) # 2
ExMachina.Sequence.next("joe") # "joe0"
ExMachina.Sequence.next("joe") # "joe1"

ExMachina.Sequence.reset(["joe", :numeric])

ExMachina.Sequence.next(:numeric, [1, 2, 3]) # 1
ExMachina.Sequence.next("joe") # "joe0"
