Unless filter

Testing RSpec
1

Hi.

Why doesn’t the following filter work?

# encoding: utf-8
# ./example_spec.rb

RSpec.configure do |config|
  config.filter = {
    unless: :condition_acceptable
  }
end

describe 'some code' do
  it 'does one', if: :condition_acceptable do
  end

  it 'does two', unless: :condition_acceptable do
  end
end

$ rspec example_spec.rb
No examples were matched # instead of 'some code does two'

Thanks.

If :condition_acceptable evaluates to false, your example will run. If
you
are looking to “match” key/values, don’t use :if or :unless

There are built-in :if and :unless filters. You probably don’t
want to override them. They work how you would normally expect.

Thanks for the clarification. I was led astray by the example from the
RSpec Book where the network dependent code was described*. In that
example the default if filter was overriden using the Proc object and
it returned true or false depending on the network condition. Now I
understand that code could be changed like the following:

class Network
  def self.available
    true # or false depending on the network condition
  end
end

describe 'some network dependent code' do
  it 'does one', :if => Network.available do # works if the network is
available only
  end

  it 'does two' do
  end
end

Unfortunately, :if and :unless were added as special cases after
rspec-2.0 and The RSpec Book were released :frowning:
