ruby - Test for warnings using RSpec -

-

Is it possible to check Ruby's warnings by using RSPC? 

  class MyClass def Start Warning "Something Wrong" End End "Warning" MyClass.new.should Warning ("Something Wrong") End < / Code>   
 
 
  warning  to  kernel  Is defined, which is included in each item if you were not getting warnings during initialization, then you can specify a warning like this:  
  obj = SomeClass.new obj. Should_receive (: warning) .with ("some messages") obj .method_that_warns It is more complicated to clarify the warning taken in the   
  initialize  method. If this should be done, you can swap and inspect it in a duplicate  IO  object for  $ stderr . Just make sure to restore it after an example  
  class MyClass def start alert "something is wrong" end myClass do @orig_stderr = $ stderr $ stderr = StringIO.new by terminating it The first description "Warns at Initialization" What to Do "MyClass.new $ stderr.rewind $ stderr.string.chomp.should eq (" Something's Wrong ") at the end of $ stderr = @orig_stderr End End  < / Pre>

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
