Wrong indentation: module inside block

[khangal]

Actual

case System.argv do
  ["--test"] ->
    ExUnit.start()

    defmodule FrequencyTest do
    use ExUnit.Case

    import Frequency

    test "final_frequency" do
    assert repeated_frequency([

    ]) == 2
end
    end
end

Expected

case System.argv do
  ["--test"] ->
    ExUnit.start()

    defmodule FrequencyTest do
      use ExUnit.Case

      import Frequency

      test "final_frequency" do
        assert repeated_frequency([

        ]) == 2
      end
    end
end
