Question

我有一个用于创建用户的POST / api / v1 / users端点。这是我对它的失败测试：

test "success" do
  user_params = %{
    user: %{
      email: "eric@spaghetti.com",
      image_url: "https://www.google.com/images/spaghetti",
    }
  }

  conn = build_conn(:post, "/api/v1/users", user_params)
  response = Router.call(conn, @opts)
  assert response.status == 201
  assert Repo.get_by(User, %{email: user_params.user.email})
  assert response.resp_body == %{
    id: "how would I know this??", #<---------this would fail since I have no way of knowing what this value would be
    email: user.email,
    image_url: user.image_url,
  } |> Poison.encode!
end

我的端点返回3个字段：email，image_url和id。我目前无法通过此测试，因为我无法分辨新创建的资源的ID是什么。有没有更好的方法来测试这个？

在这种情况下，我通常会跳过检查确切的值id，而只检查它是否存在：

%{email: email, image_url: image_url} = user

assert %{
  "id" => _,
  "email" => ^email,
  "image_url" => ^image_url,
} = Poison.decode!(response.resp_body)

您还可以声明id是一个整数：

assert %{
  "id" => id,
  "email" => ^email,
  "image_url" => ^image_url,
} = Poison.decode!(response.resp_body)
assert is_integer(id)

Phoenix API：当我不知道新资源的ID时，如何测试POST / create？
