Writing tests for a REST API

Note

The complete code listing for the tests in this section can be found at https://github.com/PacktPublishing/Web-Development-with-Julia-and-Genie/blob/main/Chapter5/TodoMVC/test/todos_API_test.jl.

It’s time to see our API in action by writing a test suite to check all the endpoints and the various scenarios we’ve implemented. Let’s start by adding a new test file for our API:

julia> touch("test/todos_API_test.jl")

Next, we’ll add the test suite to our newly created file:

using Test, SearchLight, Main.UserApp, Main.UserApp.Todos
using Genie
import Genie.HTTPUtils.HTTP
import Genie.Renderers.Json.JSONParser.JSON3
try
  SearchLight.Migrations.init()
catch
end
cd("..")
SearchLight.Migrations.all_up!!()
Genie.up()
const API_URL = "http://localhost:8000/api/v1/todos"
@testset "TodoMVC REST API tests" begin
  @testset "No todos by default" begin...
