Rspec test an example when you use an instance variable

31 Jul Rspec test an example when you use an instance variable

My test file content:

describe ProductsService do

describe '#valid?' do
  context 'when is successfully' do
    let(:result) { mock 'Result', object: {'errors' => ''}}

    before do
      subject.instance_variable_set(:@result, result)
    end

    specify do
     expect(subject.valid?).to be_true
    end
  end

 context 'when there is an error' do
  let(:result) { mock 'Result', object: {'errors' => 'error example'}}

  before do
    subject.instance_variable_set(:@result, result)
  end

  specify do
   expect(subject.valid?).to be_false
  end
 end
end

My products file content:

class ProductsService

 def first_method params
   @result = dosomething params
 end

 def valid?
   @result.object['errors'].empty?
 end

end
