如何在单元测试中测试接口返回的字段?
如果我们有一个api的entity为 employment.rb
# frozen_string_literal:truemodule API::Entities::BorrowerEntities
class Employment < API::Entity
param :in_type_id, safe_path: %i[primary_income_sourceid]
param :aaa_type, safe_path: %i[employed_code]
param :started_with_employer, safe_path: %i[started_with_employer]
end
end
let(:default_headers) { { 'CONTENT_TYPE' => 'application/json' } }
it 'xxx xxx' do
headers = { 'Authorization' => bearer_token_for(xixi.account) }.merge(default_headers)
put '/api/v1/tester/aaa', sample_entity_with('aaa_type' => 'Self-aaa').to_json, headers
expected_presenter = API::Entities::BorrowerEntities::Employment.represent(tester.account.current_aaa_detail)
expect(response_body).to eq(JSON.parse(expected_presenter.to_json))
end
详细的例子:
Grape API Entity has a"represent"method that can be usefulinspecs scenarios when we expect someobjectto be presented with some specific entity,for example when we have:
present user, with: API::Entities::User
We are actually saying:
API::Entities::User.represent(current_user) and this will give us an object like this:
#
name: "Test",
email: "test@example.com",
created_at: Mon, 14Oct201921:57:54UTC +00:00,
updated_at: Mon, 14Oct201921:57:54UTC +00:00,
@options={}>Then in our spec scenario, we can call to_json from here and use it as a expected from the response of an API call like:
get '/api/v3/user'expected_json = API::Entities::User.represent(current_user).to_json
expect(response.body).to eq(expected_json)
