Code not shown as covered

[larshesel]

Assume I have created a mix project 'covertest', the following module ./lib/covertest.ex:

defmodule Covertest do
  def x(1), do: 2
  def x(:z), do: 45
  def y(45), do: 34
end

and the following test file ./lib/covertest_test.exs:

defmodule CovertestTest do
  use ExUnit.Case

  test "covertest" do
    assert Covertest.x(1) == 2
    assert Covertest.x(:z) == 45
  end
end

Then running mix test --cover generates a report where all the lines are marked as class irrelevant in the html. I would have expected two to be marked as covered and one as not covered.

I haven't figured out where the problem is yet. I'm running Elixir 1.0.3.

So it seems running without coverex, the generated coverage is also wrong, so it's prob. a bug in the underlying coverage generation code. I'll close this for now.
