Rails 4.2 & travel_to is not working

[Cezinha Anjos]

Hi!

I have two projects running Rails 4.2 and using travel_to from ActiveSupport::Testing::TimeHelpers.

In one project everything is working perfectly. But in the second one, my specs are running with the current date/time instead of using travel_to. Here is one example:

  it "is only a travel_to test" do

    travel_to Time.new(2012, 1, 1, 1, 1, 1) do

      expect(Time.new).to eq Time.new(2012, 1, 1, 1, 1, 1)

    end

  end

I've already set the rails_helper.rb with:

RSpec.configure do |config|

  ...

  config.include ActiveSupport::Testing::TimeHelpers

end

Does anyone know what's going on?

Thanks.

What do Time.current and Time.now give you inside the block?

Bingo!

It's returning the "travel_to" time.

Do you know why?

Thanks A LOT!!!

Can you point to some documentation that says that Time.new()
initialises to current? I could not find any.

You can find here:

http://ruby-doc.org//core-2.2.0/Time.html

new → time

new(year, month=nil, day=nil, hour=nil, min=nil, sec=nil, utc_offset=nil) → time

Returns a Time object.

It is initialized to the current system time if no argument is given.

a = Time.new      #=> 2007-11-19 07:50:02 -0600

Thanks.

Yes, you are right, and since that document also says that Time.now is
an alias for this, and the docs for travel_to states that Time.now
should get the travel_to time (have you tried Time.now in the block?)
then it looks like you have found a bug.

From the doc for `travel_to` --
Changes current time to the given time by stubbing Time.now and
Date.today to return the time or date passed into this method.

If you change your test to `expect(Time.now).to ...` it will pass.

I think I have to retract this, since the docs for travel_to state
that Time.now and Time.current are stubbed then it means that Time.now
is no longer an alias for Time.new(), so there is no guarantee that
Time.new() will respect travel_to.

Hi!

I changed my code to use Time.now instead of Time.new and now everything is ok.

Do you know where can I check if this bugs is reported and if no... to report?

Thanks.

Probably our posts crossed, see my last email for reason why I don't
think this is a bug.
