Capybara::FrozenInTime error in integration specs using Rspec + Timecop + Capybara + Capybara Webkit

I'm seeing an error in some integration specs, using rspec, capybara, capybara-webkit and timecop.

Capybara::FrozenInTime:
   time appears to be frozen, Capybara does not work with libraries which freeze time, consider using time travelling instead

The only gem that I know that freezes time is Timecop, but I'm not using it in the test case that fails.

Since the error occurs only sometimes I can't even know if its gone or not after changing something.

Solution

  • The solution I found was to add

    before :each do
  Timecop.return
end

    in spec_helper.rb.

    This way we garantee that the time is not frozen before each test, although the only ones that have this problem are the ones executed in a webdriver different from rack-test. In my case capybara-webkit.
