c# - Is there a way to run a list of different action methods on an object in Nunit using TestCase? -

-

say have following:

  [test]   // parameterize parameters in call , call   public void test()   {       var res1 = _sut.method1(1);       var res2 = _sut.method2("test");       var res3 = _sit.method3(3);        assert.that(res1, is.null);       assert.that(res2, is.null);       assert.that(res3, is.null);   }

i'd parameterize tests using testcase/testcasesource attribute including call itself. due repetitive nature of tests, each method needs called different parameters, need able tag different call each of different parameters. possible in nunit? if so, how go it?

using testcasesource, should able loop on array of values , invoke desired methods, example this:

[testfixture] public class testclass {   private sut _sut;    public testclass()   {     _sut = new sut(...);   }    private ienumerable<object> testcases   {         {       var values = new object[,] { { 1, "test", 3 }, { 2, "hello", 0 }, ... };        (var = 0; < values.getlength(0); ++i)       {           yield return _sut.method1((int)values[i,0]);           yield return _sut.method2((string)values[i,1]);           yield return _sut.method3((int)values[i,2]);       }     }   }    [testcasesource("testcases")]   public void test(object val)   {     assert.that(val, is.null);   } }

note _sut instance needs instantiated in testclass constructor. not sufficient initialize within [setup] or [testfixturesetup] method.

in case need different _sut instantiations different method invocations, create collection of sut instances in constructor, , access relevant sut item within for loop of testcases getter. alternatively, loop on sut items in getter...

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...
