Selenium setup/teardown best practices- returning data to orginal state -

- 

    {         assert.that(_edituserpage.state.selectedtext, is.equalto("illinois"));         _edituserpage.state.selectedtext = "new york";         assert.that(_edituserpage.state.selectedtext, is.equalto("new york"));         _edituserpage.savechanges();         assert.that(_edituserpage.state.selectedtext, is.equalto("new york"));      }

in example above, changing user's state illinois new york; question is: should change state orignal value of illiois @ end of test?

i have 20 other independent tests in same file , wanted know best practice returning data original state. using setup/teardown entire test suite, not within each individual test.

best practice far did see this:

  1. the test had 1 test data input (excel sheet)
  2. each run add prefix data (e.g. name pavel => test01_pavel)
  3. test did verify such data not exist in system
  4. test created testing data according input , verified data present
  5. test deleted testing data , verified data deleted.

but best answer "it depends." i, personally, not deleting test data system because

  • test environment strictly divided prod one
  • test data can useful later on during performance testing (e.g. downloading list of users system)

so real question should ask is:

  • does deleting test data @ end bring you?
  • and vice versa: happens if test data remain in system?

btw, if feel "the application break if there nonsense/dummy data in it" should test scenario. imagine service become popular on night (charlie sheen tweeting using page:) ) , millions of users register themselves.

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
