问题
I have a question running already linked to this problem, but this question is for a different approach.
I have a string of text on a webpage that produces includes a timestamp (hhmmss) after a transaction is complete.
I can't use Time.now as the processing time varies depending on many factors.
The text on page is:
"Your transaction reference number is: 0 16123 (timestamp is here) A1"
I'll be looking within the element to read the text in my test with:
expect(find(location)).to have_text trans_text
Could I set the location text as a variable:
trans_text = find(location, text: 'Your transaction reference number is: 0 16123 (timestamp is here) A1')
then replace the timestamp with a regex then expect that timestamp to be between two times?
I have tried doing:
trans_text = find(location, text: 'Your transaction reference number is: 0 16123 (\d+) A1')
But had no joy. I get the following error:
Unable to find css "#main > div > div.section-content > div.two-col.retention-success > div.second-col > div.alert-complete > p" with text "Your retention certificate number is: 0 16123 (/d+) A1".
How could I input a regex to replace the timestamp part of the text?
Thanks

According to Capybara documentation:
text (String, Regexp) — Only find elements which contain this text or match this regexp
You have to search by regular expression (instead of a string):
find('p', text: /Your transaction reference number is: 0 16123 (\d+) A1/)
Or do verification in one step:
expect(page).to have_text /Your transaction reference number is: 0 16123 (\d+) A1/
