Hello!
Thank you for this great exercises 👍
I have got an error, compiling on Elixir 1.0 and can't find answer, could you help me?

** (CompileError) 04-list.exs:67: function inlist/3 undefined

http://elixir-lang.org/getting_started/ex_unit/1.html in 30-days-of-elixir 02-unit-testing.exs returns 404

Dependent on #6

is this a book? or a tutorial?

Line 29-33:

test "assert_in_delta asserts that val1 and val2 differ by no more than delta." do
  assert_in_delta 1, # actual
                  5, # expected
                  6  # delta
end

The text should says "val1 and val2 differ by less than delta".

If you change val2 to 7 you get this error (instead of passing as the text implies you would):
Expected the difference between 1 and 7 (6) to be less than 6
