My personal collection of utilities and ideas in Elixir

Iamvery Elixir

A set of Elixir utilities for myself and others. Using this Hex package as a test bed for ideas that may be eventually spun off as separate projects or open source contributions.

Installation

If available in Hex, the package can be installed by adding iamvery to your list of dependencies in mix.exs:

def deps do
  [
    {:iamvery, "~> 0.6.0", only: :test}
  ]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/iamvery.

Phoenix LiveView Test Helpers

I've put together a set of test helper functions for testing Phoenix LiveView. For more details on this pattern, see the blog post.

As a quick example, the helpers let you go from:

import Phoenix.LiveViewTest

test "live view", %{conn: conn} do
  {:ok, live, html} = live(conn, "/")
  assert html =~ "New"
  assert live |> element("a.new") |> render_click() =~ "Enter new"
  assert_patch(live, "/new")
  {:ok, _, html} = live |> form(".form", @attrs) |> render_submit() |> follow_redirect(conn)
  assert html =~ "success"
end

To:

use Iamvery.Phoenix.LiveView.TestHelpers

test "live view", %{conn: conn} do
  start(conn, "/")
  |> assert_html("New")
  |> click("a.new")
  |> assert_html("Enter new")
  |> assert_path("/new")
  |> submit_form(".form", @attrs)
  |> assert_html("success")
end
