我正在尝试进行绿色测试，但出现此错误。即使我撬开代码，它也表明返回了一个字符串，所以我不知道为什么测试不会变绿。这是我的测试和错误，以进行澄清。我假设这是人们的常见错误。
这是我的测试-
require "rails_helper"
RSpec.describe "/api/retailers" do
describe "GET /api/retailers" do
it "Returns JSON for retailers" do
location = Location.create!(
city: "Portland",
street_1: "Cherry",
state: "Oregon",
zip: "49490"
)
retailer = Retailer.create!(
name: "Good Coffee Co.",
description: "Hipster Good",
image_url: "http://www.example.com/foo_bar.jpg",
location: location
)
get "/api/retailers.json"
expect(response).to be_success
json = JSON.parse(response.body)
expect(json["name"]).to eql("Good Coffee Co.")
expect(json["description"]).to eql("Hipster Good")
expect(json["image_url"]).to eql("http://www.example.com/foo_bar.jpg")
expect(json["location"]).to eql(location.city)
end
end
end
这是我的错误信息-
/api/retailers GET /api/retailers Returns JSON for retailers
Failure/Error: expect(json["name"]).to eql("Good Coffee Co.")
TypeError:
no implicit conversion of String into Integer
# ./spec/requests/retailers_spec.rb:28:in `[]'
# ./spec/requests/retailers_spec.rb:28:in `block (3 levels) in <top (required)>'
如评论中所述，问题是JSON对象返回对象数组。因此，正确的测试期望如下：
expect(json.first["name"]).to eq("Good Coffee Co.")
expect(json.first["description"]).to eq("Hipster Good")
expect(json.first["image_url"]).to eq("http://www.example.com/foo_bar.jpg")
expect(json.first["city"]).to eq("Portland")
