active job with rails rspec - ruby-on-rails

Question

I have installed a gem rspec-rails. Everything is working fine except ActiveJob.
I have tried to implement the ActiveJob in RSpec with:
include ActiveJob::TestHelper
and here's the code for the RSsec Job Controller:
describe "#perform_later" do
it "Send Invoice Reminder" do
ActiveJob::Base.queue_adapter = :test
InvoiceReminderJob.perform_later
expect(InvoiceReminderJob).to have_enqueued_job
end
end
spec_helper.rb:
require 'rails_helper'
RSpec.describe InvoiceReminderJob, type: :job do
include ActiveJob::TestHelper
# pending "add some examples to (or delete) #{__FILE__}"
describe "#perform_later" do
it "Send Invoice Reminder" do
ActiveJob::Base.queue_adapter = :test
InvoiceReminderJob.perform("test")
expect(InvoiceReminderJob).to have_enqueued_job
end
end
end
invoice_reminder_job_spec.rb:
require 'rails_helper'
RSpec.describe InvoiceReminderJob, type: :job do
# include ActiveJob::TestHelper
# pending "add some examples to (or delete) #{__FILE__}"
describe "#perform_later" do
it "Send Invoice Reminder" do
ActiveJob::Base.queue_adapter = :test
InvoiceReminderJob.perform_later
expect(InvoiceReminderJob).to have_enqueued_job
end
end
end
When I am trying to run rspec with the command rspec I am getting the following error:
uninitialized constant ActiveJob (NameError)
Here is my Gemfile:

I have tried to search with lots of solution but I am not able to resolve this issue. If anyone could help me with it, I would be really grateful.

Answer 1

You are using rails 4.1.5, ActiveJob is introduced in rails 4.2

Answer 2

This issue is resolved by using the gem "gem 'activejob_backport'
