Получение ошибки при тестировании исключения в приватном методе.Как проверить, что исключение возникает в приватном методе, который вызывается из публичного метода?
Public
def public_method
private_method
end
Private
def private_method
tries = 0
begin
raise Product::StaleObjectError.new("Product is changed while you were editing") if stale_object?
// Do some work
raise Exception.new("Total amount used is greater than approved") if total_approved < 0
// Save Product
rescue Product::StaleObjectError => e
if tries < MAX_RETRIES
tries += 1
sleep(1 + tries)
reload
retry
else
raise Product::StaleObjectError("Product is changed while you were editing")
end
end
attributes
end
Test Case:
before(:each) do
@prod_v1 = Product.new
end
it 'if product stale, then an exception should raise' do
Product.any_instance.stub(:stale_object?).and_return(true)
expect_any_instance_of(Product).to receive(:private_method).and_raise(Product::StaleObjectError.new("Product is changed while you were editing"), nil)
@prod_v1.public_method
end
Я получаю следующую ошибку для контрольного примера
Failure/Error: @product_v1.private_method
Product::StaleObjectError:
Product is changed while you were editing
# ./app/models/product.rb:10:in `private_method'
# ./spec/models/product_spec.rb:67:in `block (4 levels) in <top (required)>'
Я попытался изменить структуру контрольного примера, но все еще получаю ошибки.
it 'if product stale, then an exception should raise' do
Product.any_instance.stub(:stale_object?).and_return(true)
expect_any_instance_of(Product).to receive(:private_method).and_raise(Product::StaleObjectError.new(nil, nil))
@prod_v1.public_method
end
Ошибка
Failure/Error: expect_any_instance_of(Product).to receive(:private_method).and_raise(Product::StaleObjectError.new(nil, nil))
