EOF end of file reached about rspec-benchmark HOT 3 CLOSED

If I replace, expect { 1000.times { subject.update_transactions_for(payment) } }.to perform_under(50).ms with expect { 1000.times { 'a' + 'b' } }.to perform_under(50).ms, it passes.

This seems to be related to an external request being made. Once I added VCR, things worked fine.

Hi Maros,

Thank you for using this gem! 🙏

rspec-benchmark only adds assertions which do not handle any IO operations per say.

In your specific case, I would suggest changing your example to:

expect { 
  subject.update_transactions_for(payment)
}.to perform_under(50).ms.sample(1000).times

This will provide a benefit of calculating an average run of the expectation and more stable results. Otherwise you're missing out on the benefits of using the expectation.
