objective c - Can XCTAssertThrows catch c++ exception? -

-

I am using Exstate to test some C ++ / OC mixed code units. I think it seems that XCTAssertThrows can not take exceptions c ++?

My use is very simple

Say, as an expression c ++ test () 

    < p> Any suggestions?

 Wrap  
 
 Long answer: You can wrap NSE expansion for any std :: exception, like << p> 
  #import & lt; XCTest / XCTest.h & gt; #import & lt; Exceptions & gt; @interface NSException (ForCppException) @end @implementation NSException (ForCppException) - (id) initWithCppException: (std :: exception) cppException {NSString * Description = [NSString stringWithUTF8String: cppException.what ()]; Return [self-initWithName: @ "cppException" Reason: Description userInfo: zero]; } @end @interface XCTestCase (ForCppException) @end @implementation XCTestCase (ForCppException) - (zero) rethowNSExceptionForCppException: (zero (^) ()) ACTION {ACTION (try {); } Hold (const std :: exception & e) {@throw [[NSException alloc] initWithCppException: e]; }} @end #define XCTAssertCppThrows (Expression, Format ...) \ XCTAssertThrows ([self rethowNSExceptionForCppException: ^ {expression;}], ## format)   
 Use this like this:  
  #pragma mark - test void foo () {std :: exception (); } Zero Times () {} @ Interface Test Test: XctestCase @ @ @ Implementation Test Test - Examples (empty) Examples {XCTAssertCppThrows (foo (), @ "Exception should be teaser"); // Successful XCTAssertCppThrows (bar (), @ "should be refracted"); // failed} @end

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
