is there common way test complex functions several parameters nunit? think hard or impossible test every condition. i'm afraid combination of parameters isn't expected in function not expected in test. so expected condition not fail unexpected. thanks this shouldn't hard test @ all. if is, method isn't designed testability, , code smell tells you need refactor it. i tend write tests in these cases follows (others may have better suggestions): does work intended when appropriate parameters passed? does throw expected exceptions when think should? (argumentnullexception, etc.) for each parameter, happens when pass null, minimum , maximum. (this can extensive, depending on number of arguments.) if method takes lot of parameters, consider refactoring take object information on it, can encapsulate rules in object, , pass object method.

i want use regular expression following thing ( extracted part i'm in trouble in order simplify ): character 1 5 first characters, "underscore", digits, "underscore", digits or dot. with restriction on "underscore" should give that: ^([^_]{1,5})_([\\d]{2,3})_([\\d\\.]*)$ but want allow "_" in 1-5 first characters in case still match end of regular expression, example if had somethink like: to_to_123_12.56 i think linked eager problem in regex engine, nevertheless, tried lazy stuff explained here without sucess. any idea ? i used following regex , appeared work fine task. i've replaced initial [^_] . . ^.{1,5}_\d{2,3}_[\d\.]*$ it's best replace final * + too, unless allow nothing after final '_'. , note final part allows multiple '.'

this complex situation ain. have booking system rooms booked. the thing rates rooms aren't stored single value period based. room can have 1 daily rate between september december , adifferent rate march august, while have base rate other wise. the rates table this: roomid | rate | period_start | period_end lets suppose rate room between 1st march 31st march 20 dollars/day , rate same room 15th april 30th may 30 dollars, aside rate flat rate of 15 dollars/day. if room booked 1 client between 15th march 10th may, total cost be: 15th march - 31st march charged @ 20 dollars/day = 16x20 1st april - 14th april charged @ 15 dollars/day = 14x15 15th april - 10th may charged @ 30 dollars/day = 25x30 now how can compute value in code, need compute thenumber of days based upon rate periods if any, else use base rate them. complex thats how is. i'm using php mysql this possible solution algorithm: find rate periods have non-empty intersection booking period f

i curious know how functions related synchronization between processes , threads implemented inside unix means happens when call pthread_mutex_lock?? pointers?? or source code help. it both complicated , differs unix unix variant. in linux, example, system called futex (short fast userspace mutex) used. in system atomic increment , test operation performed on mutex variable in user space. if result of operation indicates there no contention on lock, call pthread_mutex_lock returns without ever context switching kernel, operation of taking mutex can fast. only if contention detected system call (called futex) , context switch kernel occurs puts calling process sleep until mutex released. there many many more details, reliable and/or priority inhertience mutexes, essence of it. for more details see: http://linux.die.net/man/2/futex , http://en.wikipedia.org/wiki/futex

i have been working on new mvc application utilizies ef4, poco domain objects , repository <--> service layer. i see lot of talk using automapper map ef4 classes dto view models. under impression rid of tightly bound ef4 classes. question since using poco classes, can't use in view models? or there still need automapper? the argument "poco's" domain models, , view's shouldn't concerned domain models. think way - data validation, if want data annotations, have put them on poco's - input validation (this field required, etc) isn't domain concern, it's ui concern - hence use of viewmodels data annotations , automapper. of course, it's not cut , dry, it's matter of preference. i use mvc/ef4/poco/automapper/service layer , never bind poco's - use viewmodel per view. this way, have level of consistency: all view's have viewmodel poco's have nothing business/domain logic viewmodel's have basic inpu
