我正在使用FactoryGirl
和Rspec
編寫一些測試。使用Rspec在多個上下文之間傳遞變量
規格/工廠/ students.rb:
FactoryGirl.define do
factory :student do
end
factory :student_with_profile_and_identity, class: 'Student' do
after(:create) do |student|
create(:profile, profileable: student)
create(:student_identity, student: student)
end
end
end
規格/工廠/ profiles.rb:
FactoryGirl.define do
factory :profile do
birthday { Faker::Date.birthday(15, 150) }
sequence(:email) { |i| "profile_#{i}@email.com" }
first_name { Faker::Name.first_name }
last_name { Faker::Name.first_name }
password { Faker::Internet.password(6, 72, true, true) }
end
end
規格/工廠/ student_identities.rb:
FactoryGirl.define do
factory :student_identity do
provider { ['facebook.com', 'google.com', 'twitter.com'].sample }
uid { Faker::Number.number(10) }
end
end
規格/請求/ authorizations_spec.rb:
require 'rails_helper'
RSpec.describe 'Authorizations', type: :request do
describe 'POST /v1/authorizations/sign_in' do
let!(:student) { create(:student_with_profile_and_identity) }
context 'when the request is valid' do
subject do
post '/v1/authorizations/sign_in',
params: credentials
end
context "user signs up via social network" do
let(:credentials) do
{
authorization: {
student: {
profile_attributes: {
email: student.profile.email
},
student_identities_attributes: {
provider: student.student_identities[0].provider,
uid: student.student_identities[0].uid
}
}
}
}
end
it 'returns an authentication token' do
subject
p "1 student.profile.inspect #{student.profile.inspect}"
expect(json['token']).to(be_present)
end
end
context 'when the user has already an account' do
let(:credentials) do
{
authorization: {
email: student.profile.email,
password: student.profile.password
}
}
end
it 'returns an authentication token' do
p "2 student.profile.inspect #{student.profile.inspect}"
subject
expect(json['token']).to(be_present)
end
end
end
end
end
幾乎所有的測試都通過......問題是:
它創建一個新的學生在每一個方面。我期望let!(:student) { ... }
是類似「singleton」,換句話說,一旦它在這裏被創建/定義let!(:student) { create(:student_with_profile_and_identity) }
它將不會再被調用。
實例:在日誌是這樣的:
"1 student.profile.inspect #<Profile id: 1, email: \"[email protected]\", profileable_type: \"Student\", profileable_id: 1>"
"2 student.profile.inspect #<Profile id: 2, email: \"[email protected]\", profileable_type: \"Student\", profileable_id: 2>"
雖然我期望的情況下是相同的。
我錯過了什麼嗎?
