问题描述
我正在尝试将 POST 请求存根到外部 API。规范测试不会用我的假变量替换 ENV 变量,而是在返回此错误的存根请求中转到我的本地环境 (localhost:3000
):
Failure/Error: response = http.request(request)
WebMock::NetConnectNotAllowedError:
Real HTTP connections are disabled. Unregistered request: POST http://localhost:3000/Target with body '{"name":"Wayfarer"}' with headers {'Accept'=>'*/*','Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3','User-Agent'=>'Ruby'}
You can stub this request with the following snippet:
stub_request(:post,"http://localhost:3000/Target").
with(
body: "{\"name\":\"Wayfarer\"}",headers: {
'Accept'=>'*/*','User-Agent'=>'Ruby'
}).
to_return(status: 200,body: "",headers: {})
我的测试是:
let!(:user) { create(:user,target: 'Wayfarer') }
before(:each) do
allow(ENV).to receive(:fetch).with('API_METADATA_URL').and_return('http://example.com')
end
describe '#create_target' do
context 'successful API request to create target' do
it 'sends data to API and sets response instance variables' do
target = user.target
stub_request(:post,'http://example.com/Target').with(
headers: {
},body: '{
"name": "Wayfarer"
}'
).to_return(
status: 200,body: '{"id": "uuid",' \
'"name": "Wayfarer",' \
'"created_at": 00000,' \
'"updated_at": 00000}'
)
api_client = ApiClient.new
api_client.create_target(target)
expect(api_client.response_status).to eq(200)
expect(api_client.response_body).to eq(
{
'id' => 'uuid','name' => 'Wayfarer','created_at' => 00000,'updated_at' => 00000
}
)
end
end
end
它甚至没有通过测试,反而似乎运行了 ApiClient,包括使用我的本地环境变量(如上所述)。
解决方法
我最终需要一个单独的 .env
文件用于测试 (.env.test.local
) 的 API_METADATA_URL
用于未引发错误的网址。
