How do i removed these depreciation warnings?

I'm not really sure why they're happening (it's related to rspec 2.99), but you can get rid of them by adding the following to spec_helper.rb

config.expose_current_running_example_as :example

The answer:

expose_current_running_example_as :example config option is meant to support users who are using gems that depend on the RSpec 2 API. It's not meant for library authors to use.

The source if you wan to check more.

Cool!

It continues to work as Jul, 14, 2015.

I passed the following snippet at very end of odot/spec/spec_helper.rb. The log suggests a slightly different notation, so I used the following:

RSpec.configure do |c|
  # RSpec::Core::ExampleGroup#example is deprecated and will be removed in RSpec 3.
  # [...] snippet to continue making this method available in RSpec 2.99 and RSpec 3:
  c.expose_current_running_example_as :example
end

# VM spec
# uname --all
# Linux treehouse 3.8.0-33-generic #48~precise1-Ubuntu SMP Thu Oct 24 16:31:16 UTC 2013 i686 i686 i386 GNU/Linux

Everything works with a clean log after the addition.

By running this command, it exposes the current running example via the named helper method. Since we're using extension gem Capybara in this tutorial, this config option is used to maintain compatibility between different versions of Rspec.

There's some more information about depreciation warnings on upgrading to rspec3 here: http://rspec.info/upgrading-from-rspec-2/

I used the transpec tool to remove 7 warnings and the last two by adding the config line above

The answer string on this question is a little convoluted. The specific solution seems to depend on the exact depreciation error that comes up and what the code in your odot/spec/spec_helper.rb file looks like.

If you see this:

rspec-rails 3 will no longer automatically infer an example group's spec type
from the file location. You can explicitly opt-in to this feature using this
snippet:

RSpec.configure do |config|
  config.infer_spec_type_from_file_location!
end

then add this to the Rspec.configure do |config| block just above the line that contains end.

config.infer_spec_type_from_file_location!

My spec_helper.rb file already contained that line of code. My depreciation warning looked like this:

RSpec::Core::ExampleGroup#example is deprecated and will be removed                                           
in RSpec 3. There are a few options for what you can use instead:                                             

  - rspec-core's DSL methods (`it`, `before`, `after`, `let`, `subject`, etc)                                 
    now yield the example as a block argument, and that is the recommended                                    
    way to access the current example from those contexts.                                                    
  - The current example is now exposed via `RSpec.current_example`,                                           
    which is accessible from any context.                                                                     
  - If you can't update the code at this call site (e.g. because it is in                                     
    an extension gem), you can use this snippet to continue making this                                       
    method available in RSpec 2.99 and RSpec 3:                                                               

      RSpec.configure do |c|                                                                                  
        c.expose_current_running_example_as :example                                                          
      end 

The solution is to add this to the Rspec.configure do |c| block just above the line that contains end.

c.expose_current_running_example_as :example 

However, my spec_helper.rb file does not contain a Rspec.configure do |c| block. Instead it has Rspec.configure do |config|.

In this case, the solution is to add this to the Rspec.configure do |config| block just above the line that contains end.

config.expose_current_running_example_as :example

What are deprecation warnings and why do these code snippets make them go away?

A depreciation warning tells you that in the next version of the software something will not work the way that it is working now in the current version. Adding these snippets explicitly tells rspec to continue behaving the same if and when you upgrade it to the next version. If a depreciation warning is ignored and the software is upgraded it will probably break your code and you'll have to rewrite a bunch of it to make it work again.

Thanks!

Does anyone want to explain why and how this works? :)

I would also like an explanation as to what's happening here. Thanks.

Thank you for this, it worked!

Thank you for the tip, worked like a charm!

Thanks a million for this :)

I had identical message.

I added : config.expose_current_running_example_as :example

to the spec_helper.rb

inside the RSpec.configure do |config| block at the bottom just before end.

I had a larger message and I simply added

RSpec.configure do |c| c.expose_current_running_example_as :example end

to the spec_helper.rb file in the spec folder :)
