With clause in the controller gets missing coverage, works when has some calculation before

[anantanant2015]

For example if working on the user update:

def update(conn, params) do
  with {:ok, user} <- User.update(params) do
    render(conn, "user.json", user: user)
  end
end

Here with {:ok, user} <- User.update(params) do this line is left uncovered.

If we wish to cover this, or the cases where these type of blocks gets covered:

def update(conn, params) do
   user = conn.assigns.user

  updated_params =
    params
    |> Map.put("store_uuid", user.store_uuid)
    |> Map.put("created_by", user.user_uuid)

   with {:ok, user} <- User.update(params) do
    render(conn, "user.json", user: user)
  end
end

Hi. Thank you for the comment. I'm afraid that certain lines (statements) can be taken as uncovered. The following might be related.

• Lines in a case statement are treated as irrelevant #49

I'm not sure if it matches your expectation, but one option could be to ignore certain lines.
