ruby - Rewrite shared example groups in rspec2 -

-

in rspec 1 

describe "something", :shared => true  include somemodule # has :a_method method   def a_method(options)    super(options.merge(:option => @attr)  end   "foofoofoo"  end end  describe "something else"   before(:each)     @attr = :s_else   end    it_should_behave_like "something"    "barbarbar"     a_method(:name => "something else")     something.find("something else").name.should == "something else"   end ... end

that is, use :shared => true not refactor examples share method definitions , attributes. realize example contrived, how 1 write in rspec >= 2 without touching somemodule module or something class?

you can shared_examples_for

shared_examples_for "something"   include somemodule # has :a_method method    def a_method(options)     super(options.merge(:option => @attr))   end    "foofoofoo"   end end

and call it_behaves_like:

it_behaves_like "something"

edit

joao correctly points out fails include somemodule examples in describe block. include have take place outside shared example group, e.g. @ top of spec file

include somemodule # has :a_method method  # ...  shared_examples_for "something"   def a_method(options)     super(options.merge(:option => @attr))   end    "foofoofoo"   end end

david chelimsky discusses new features of shared examples in rspec 2 may pertinent in this blog post.

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
