Failures:

  1) PrivacyFilter does not filter invalid phone numbers
     Failure/Error: filter(text).should eq filtered
       
       expected: "Reach me at: 0885123"
            got: "Reach me at: [PHONE]"
       
       (compared using ==)

  2) Validations can validate more complex phone numbers

       expected #<FalseClass:0> => false
            got #<TrueClass:2> => true
       
       Compared using equal?, which compares object identity,
       but expected and actual are not the same object. Use
       'actual.should eq(expected)' if you don't care about
       object identity in this example.
