Selectors
expect(page).to have_button('Save')
expect(page).to have_button('#submit')
expect(page).to have_button('//[@id="submit"]')
The selector
arguments can be text, CSS selector, or XPath expression.
RSpec assertions
page.has_button?('Save')
expect(page).to have_no_button('Save')
In RSpec, you can use page.should
assertions.
About negatives
expect(page).to have_no_button('Save') # OK
expect(page).not_to have_button('Save') # Bad
Use should have_no_*
versions with RSpec matchers because
should_not have_*
doesn’t wait for a timeout from the driver.
