Capybara testing if page has regular expression

Question

I'm new to RSpec and Capybara and I am trying to test if page has a time on it. 12:00 or 14:24 or 08:12 are good examples of what I am trying to test for.

I am using the following regex:

/^\d{2}:\d{2}/

I am not sure how to "phrase it" in capybara to test if the page contains this regex.

Answer 1

I'd suppose something like

page.text.should match(/^\d{2}:\d{2}/)

or, with the new RSpec syntax

expect(page.text).to match(/^\d{2}:\d{2}/)

Or you can test not the whole page but some element, e.g.

find("span.time").text.should match(/^\d{2}:\d{2}/)

Answer 2

I don't know if this is new behavior, but you can just use has_content?:

page.has_content?(/do not have permission/i)

In rspec, that would be something like this:

expect(page).to have_content(/do not have permission/i)

I found this in the online documentation for capybara, but it's under has_text? since has_content? is just an alias.
