AssertFunctional

Functional and composable assertions for your elixir tests. They especially clean up testing the result of pipelines:

Instead of this:

conn =
  build_conn()
  |> post("/upload_content_cover", params)


assert %{"success" => true} = json_response(conn, 200)

You can write this:

build_conn()
|> post("/upload_content_cover", params)
|> json_response(conn, 200)
|> assert_match(%{"success" => true})

Currently the only implemented assertions are assert_equal and assert_match. Pull request for improvement are welcome.
