Using a generative test library in clojure vs build your own using higher order functions -

-

Closer has many libraries, such as generating testing, or

It is possible to use higher command functions such as compose to create random data generators: 

  (defn gen [create-fn content-fn lazy] ( Fn [] (# lower -fn% 1% 2) (for [a lazy] (content-fn))) (def one (gen str # (rand-nth [\ a \ b \ c]) ( Limit 10)) (DEF B (Normal vector # (Rand-At 10) (Range 2)) (B) (Diff C (Gene hash-set B (category (RAND-int10))) () C)   
 This is just an example and modified with data parameters, filters, partial etc. Can be obtained in order to be flexible enough data creation functions.  
 Is there anything that can do this to any productive libraries, by typing some high order tasks, not even in the form of short (or more)?  
 As an aside for the Stackworflow deities: I do not believe this question is subjective. I am not asking for any opinion on which the library is better. I want to know that  specific feature (or) (techniques)  of any / all data generative libraries separates them from making vanilla high order functions. In response to an example, using any libraries should clarify the generation of random data, as I have said that by preparing the HOF it would be more complicated to do this so that I did this in the way described above.  
 
 
 
 test.check better  method  most especially, the value Take that you generate a random list of 100 elements, and fails your exams: The list you handled that list is wrong. now what? How do you find the original bug? It really does not depend on those 100 inputs; You may possibly reproduce it with a list of some elements or an empty list if something in your base case is wrong.  
 This feature that really makes sense, it is not a random generator, it is "shrinking" of those generators, once test.check finds the input that breaks your tests, this input can be as much as possible Try to make that simple, while still breaking your test. For a list of integers, the contracts are quite simple, you can probably do them yourself: remove any element, or reduce any element. Switch to even it really can not be too: Maybe I want to select the order of the hard work I, I know. And for larger input, such as from the vector to the 3-topless list of the map [string, int, keyword] you will find it completely inconvenient, while test.check has already done all the hard work.

I am trying to learn PDO, now I have written this small code, but it gives me a serious error: < P> Fatal error: Call a member function at a non-object dot () ... $ con = new mysqli ("127.0.0.1", "root", "", "csvdangercheck"); $ Query = $ con- & gt; ("Id,` var1`, `var2`) values ​​(" id,: var1,: var2) ";); $ query- & gt; bypass pattern (': id', $ id); $ query- & gt; BindParam (': var1', $ VAL1); $ Query- & gt; bindParam (': var2', $ val2); $ Query-> Executed (); I Trying to use print_r ($ con-> errorInfo ()) but Fatal error: Undefined method mysqli :: errorInfo ( ) ... can someone tell me what am I missing? Flaffeh said, you have PDO Missing Mysqy, try it: $ con = new PDO ('mysql: host = 127.0.0.1; dbname = csvdangercheck', 'root', '');

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
