Wormwood is a small open source lib to help unit test GraphQL query documents against an Absinthe API. It requires no Plug.Conn s and removes lots of boilerplate using macros!

You can load in a GQL document file using a simple macro, and quickly execute the query against your Absinthe schema!

Simple example:

defmodule Wormwood.Test.Examples.GetUsersTest do
  use ExUnit.Case
  use Wormwood.GQLCase

  load_gql My.Absinthe.Schema, "assets/GetUsers.gql"

  describe "GetUsers.gql" do
    test "Should return a list of all the users" do
      # running the query! No conn or JSON required.
      result = query_gql(variables: %{}, context: %{:current_user => ...}) 
      assert {:ok, query_data} = result
      # ...
    end
  end
end

Quick Feature List:

• Avoid’s boilerplate code when unit testing your Absinthe API.
• Pass context, and variables into your query using the query_gql/1 function.
• Supports #import statements in GQL documents for fragments!
• Executes GQL document files and plain query strings.
• Allows you to test the same query documents you ship to your users!
• Provides methods to help query using a custom Absinthe pipeline.
