The use of doubles or from rspec-mocks outside of the per-test lifecycle is not supported

[belgoros]

If is not supported, what is the right way to mock an object once before all the examples ?

Here is what I tried to do and failed:

describe '#build_working_hour' do

  context "for open status" do
      before(:all) do
        @schedule = double(MystoreMigration::StoreSchedule, am_start_time: 900, pm_end_time: 2030)
        allow(@schedule).to receive(:has_divided_hours?).and_return(false)
        allow(@schedule).to receive(:closed?).and_return(false)
        @working_hour = store_migrator.build_working_hour(schedule)
      end


      it 'should init working hour with open status' do
        expect(@working_hour.open?).to be_truthy
      end


      it 'should init working hour with open status times' do
        expect(@working_hour.opens).to eq(32_400_000)
        expect(@working_hour.closes).to eq(73_800_000)
        expect(@working_hour.divided_opens).to be nil
        expect(@working_hour.divided_closes).to be nil
      end
    end
end

What is wrong with the above approach ? I'd like to 1) check a status, 2) the assigned values. Thank you!

I figured out after reading the docs:

Mocks are only supported in before(:example).

So the only way to get it working is to use 

before(:example)

  hook.

Hope this helps.

That works, or you can use `RSpec::Mocks.with_temporary_scope { ... }` to create a scope for use within your `before(:all)` hook.  See this for more information:
