Rspec tests in Rails suddenly start to fail - ruby-on-rails

Question

I was changing some parts of code, and my tests started to give errors and warnings.
Then I removed those tests, because I couldn't fix them.
But then tests in my other file totally went awry.
The following is my factories.rb file:
FactoryGirl.define do
factory :user do
sequence(:name) { |n| "Person #{n}" }
sequence(:surname) { |n| "Persona #{n}" }
sequence(:email) { |n| "person_persona_#{n}#example.com.eu" }
password "foobar"
password_confirmation "foobar"
# factory :admin do
# admin true
# end
factory :admin do
role "admin"
end
factory :editor do
role "editor"
end
factory :author do
role "author"
end
end
factory :course do
sequence(:title) { |n| "Title #{n}" }
sequence(:objectives) { |n| "Objectives #{n}" }
user_id 1
subject_id 1
student_level_id 1
end
factory :subject do
title "French for Adults"
end
factory :student_level do
title "Advanced"
end
end
And this is my actual test file, models/course_spec.rb:
require 'spec_helper'
describe Course do
let (:user) { FactoryGirl.create(:user) }
let (:subject_) { FactoryGirl.create(:subject) } # "_" so that to differenciate from subject test directive
let (:student_level) { FactoryGirl.create(:student_level) }
before do
# #course = Course.new(user_id: user.id, subject_id: subject_.id, student_level_id: student_level.id,
# title: "French for Us", objectives: "Lorem ipsum")
#course = user.courses.build(title: "French", objectives: "lorem")
#course.subject = subject_
#course.student_level = student_level
end
subject { #course }
it { should respond_to(:user_id) }
it { should respond_to(:subject_id) }
it { should respond_to(:student_level_id) }
it { should respond_to(:title) }
it { should respond_to(:objectives) }
it { should respond_to(:user) }
its(:user) { should == user }
it { should be_valid }
describe "when user_id is not present" do
before { #course.user_id = nil }
it { should_not be_valid }
end
describe "when subject_id is not present" do
before { #course.subject_id = nil }
it { should_not be_valid }
end
describe "when student_level_id is not present" do
before { #course.student_level_id = nil }
it { should_not be_valid }
end
describe "when title is not present" do
before { #course.title = "" }
it { should_not be_valid }
end
describe "when title is too long" do
before { #course.title = "a" * 251 }
it { should_not be_valid }
end
describe "when title is already taken" do
before do
course_with_same_title = #course.dup
course_with_same_title.title = #course.title.upcase
course_with_same_title.save
end
it { should_not be_valid }
end
describe "when objectives are not present" do
before { #course.objectives = "" }
it { should_not be_valid }
end
describe "accessible attributes" do
it "should not allow access user_id" do
expect do
Course.new(user_id: user.id)
end.to raise_error(ActiveModel::MassAssignmentSecurity::Error)
end
# it "should not allow access subject_id" do
# expect do
# Course.new(subject_id: subject_.id)
# end.to raise_error(ActiveModel::MassAssignmentSecurity::Error)
# end
# it "should not allow access student_level_id" do
# expect do
# Course.new(student_level_id: student_level.id)
# end.to raise_error(ActiveModel::MassAssignmentSecurity::Error)
# end
end
end
And these are test outputs:

I suppose there is problem with factories.rb file. But I checked it with the same file on other branch, nothing changed actually.
What could be wrong here?

Answer 1

I ran
$ rake db:test:prepare
per this thread: Suddenly ALL RSpec tests failing?
And everything worked fine.

Answer 2

I suggest you check the following things
schema, migration: make sure your object has the correct attributes
model validation: this is highly the reason that cause your test fail. Last time I had this invalid_record error is because of a validation fault
