• XML XHR Request resultin in 0 stauts and empty response text.

  - by deepak

  I had another post for the same problem... I think I put the question in a wrong way.. Let me give more details: i have test.html in my c:\ drive and I have a local webserver runnin in qt, and i have some plugin written to that webserver which will get the request and send some response text "hello". in test.html i m making a xml xhr request which will make a GET request like localhost:8080/test which will return the text "hello" by that plugin. Now if I directly open test.html from C:\ it doesnt work, i mean i get response 4 and status 0, and response text nothing.. but the request is passing through webserver and plugin It works fine, when the test.html is put in the webserver pages directory.

• Why must use "out" instead of ref ?

  - by Phsika

  i wrote some code blocks about ref -out declaration. i think that ref is most useful out. Ok. why i need to use out. i can use always ref everytime: namespace out_ref { class Program { static void Main(string[] args) { sinifA sinif = new sinifA(); int test = 100; sinif.MethodA(out test); Console.WriteLine(test.ToString()); sinif.MethodB(ref test); Console.WriteLine(test.ToString()); Console.ReadKey(); } } class sinifA { public void MethodA(out int a) { a = 200; } int _b; public void MethodB(ref int b) { _b = b; b = 2*b; } } }

• Visual Studio 2012 testing with csla and entity framework

  - by Jamie Altizer

  In VS2010 my MSTest test run just fine. When running in VS2012 I am getting an error. The test sets the Csla.ApplicationContext.User with a Custom Business Principal. When EntityFramework is asked to provide a new ObjectContext I receive a SerializationException saying that my Custom Business Principal type cannot be found. So far all tests that use EntityFramework fail when running through VS2012's test runner or Resharper7's test runner. I have tried NCrunch's test runner and they all pass. Thank you in advance.

• Java newbie problem: classes of the same package accessing one another?

  - by HH

  Test.java and SetWord.java belong to the package tools. Test.java needs to access SetWord but an odd error 'cannot find' SetWord appear. The package limits the visibility, it works without 'package tools;' lines. How can I acess the SetWords with Test in the same pkg? In general, how can classes access one another in the same pkg? Test.java package tools; import java.io.*; import java.util.*; public class Test{ public static void main(String[] args) { //IT CANNOT FIND SetWords despite the same folder, why? SetWord sw=new SetWord(); System.out.println(st.set("HELLO)"); } } SetWord.java package tools; import java.io.*; import java.util.*; public class SetWord{ public SetWord(){} public String set(String s) { return s.trim().toLowerCase(); } }

• JPA and aggregate functions. How do I use the result of the query?

  - by Bogdan

  Hey guys, I'm new to ORM stuff and I need some help understanding something. Let's assume I have the following standard SQL query: SELECT *, COUNT(test.testId) AS noTests FROM inspection LEFT JOIN test ON inspection.inspId = test.inspId GROUP BY inspection.inspId which I want to use in JPA. I have an Inspection entity with a one-to-many relationship to a Test entity. (an inspection has many tests) I tried writing this in JPQL: Query query = em.createQuery("SELECT insp, COUNT(???what???) FROM Inspection insp LEFT JOIN insp.testList " + "GROUP BY insp.inspId"); 1) How do I write the COUNT clause? I'd have to apply count to elements from the test table but testList is a collection, so I can't do smth like COUNT(insp.testList.testId) 2) Assuming 1 is resolved, what type of object will be returned. It will definitely not be an Inspection object... How do I use the result?

• Rails + RSpec problem

  - by FancyDancy

  I have just installed Rspec and Rspec-rails. When i try to run the test, it says: rake aborted! Command /opt/local/bin/ruby -I"lib" "/opt/local/lib/ruby/gems/1.8/gems/rspec-1.3.0/bin/spec" "spec/controllers/free_controller_spec.rb" --options "/Volumes/Trash/dev/app/trunk/spec/spec.opts" failed Full log here: http://pastie.org/939211 However, my second "test" application with sqlite works with it. I think the problem is in my DB. My ruby version is 1.8.7, i use mysql as database. My files: specs/spec_helper.rb config/environment.rb config/environments/test.rb List of my gems My test is just: require 'spec_helper' describe FreeController do it "should respond with success" do get 'index' response.should be_success end end I really can't understand the error, so i don't know how to fix it.. Additional question: should i use a fixtures and ActiveRecord, if i going to use Machinist for creating test data? What should i do to disable them?

• nUnit Assert.That(method,Throws.Exception) not catching exceptions

  - by JasonM

  Hi Everyone, Can someone tell me why this unit test that checks for exceptions fails? Obviously my real test is checking other code but I'm using Int32.Parse to show the issue. [Test] public void MyTest() { Assert.That(Int32.Parse("abc"), Throws.Exception.TypeOf<FormatException>()); } The test fails, giving this error. Obviously I'm trying to test for this exception and I think I'm missing something in my syntax. Error 1 TestCase '.MyTest' failed: System.FormatException : Input string was not in a correct format. at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) at System.Int32.Parse(String s) based on the documentation at Throws Constraint (NUnit 2.5)

• Problematic behavior of Linq Union?!

  - by Foxfire

  Hi, consider the following example: public IEnumerable<String> Test () { IEnumerable<String> lexicalStrings = new List<String> { "test", "t" }; IEnumerable<String> allLexicals = new List<String> { "test", "Test", "T", "t" }; IEnumerable<String> lexicals = new List<String> (); foreach (String s in lexicalStrings) lexicals = lexicals.Union (allLexicals.Where (lexical => lexical == s)); return lexicals; } I'd hoped for it to produce "test", "t" as output, but it does not (The output is only "t"). I'm not sure, but may have to do something with the deferred processing. Any ideas how to get this to work or for a good alternative?

• Phonegap 2.1 for Android - Hello World App 3 errors at launch

  - by noway

  I developed something with Phonegap for iOS, but this is my first trial for Android. I created my hello world application with CLI sth like this mentioned here: $ /path/to/cordova-android/bin/create /path/to/my_new_cordova_project com.example.cordova_project_name CordovaProjectName Even though I created this app in Eclipse Workspace, I needed to import it to Eclipse. I created two AVDs. One for API level 8, one for API level 16. When I try to build, it gives me these three errors and a warning. What is wrong with my setup?

• Automatically create valid links

  - by Marcos Placona

  Hi, I'm new to python, so please bare with me :) I was wondering if there's any built-in way in python to append variables to URL's regardless of it's structure. I would like to have a URL variable (test=1) added to an URL which could have any of the following structures http://www.aaa.com (would simply add "/?test=1") to the end http://www.aaa.com/home (like the one above, would simply add "/?test=1") to the end http://www.aaa.com/?location=home (would figure out there's already a ? being used, and would add &test=1 to the end) http://www.aaa.com/?location=home&page=1 (like the one above, would figure out there's already a ? being used, and would add &test=1 to the end) I'd be happy to write domething to do it myself, but if python can already do it somehow, I'd me more than happy to use any built-in functionality that would save me some time ;-) Thanks in advance

• how does memory stacks work in javascript

  - by user227353

  When we have code like: function a(){ var x =0; this.add=function(){ alert(x++); } } var test = new a(); test.add(); // alert 0 test.add(); // alert 1 test.add(); // alert 2 How does this work? Doesn't that the value of 'x' in a() should be 'gone' as soon as test = new a() is complete? The stack contains x should also be gone as well, right? Or, does javascript always keep all the stacks ever created in case they will be referenced in future? But that wouldn't be nice, would it...?

• Python: How to run unittest.main() for all source files in a subdirectory?

  - by Pete

  I am developing a Python module with several source files, each with its own test class derived from unittest right in the source. Consider the directory structure: dirFoo\ test.py dirBar\ __init__.py Foo.py Bar.py To test either Foo.py or Bar.py, I would add this at the end of the Foo.py and Bar.py source files: if __name__ == "__main__": unittest.main() And run Python on either source, i.e. $ python Foo.py ........... ---------------------------------------------------------------------- Ran 11 tests in 2.314s OK Ideally, I would have "test.py" automagically search dirBar for any unittest derived classes and make one call to "unittest.main()". What's the best way to do this in practice? I tried using Python to call execfile for every *.py file in dirBar, which runs once for the first .py file found & exits the calling test.py, plus then I have to duplicate my code by adding unittest.main() in every source file--which violates DRY principles.

• Confused by "let" in Clojure

  - by Tom Dalling

  I just started playing with Clojure, and I wrote a small script to help me understand some of the functions. It begins like this: (def *exprs-to-test* [ "(filter #(< % 3) '(1 2 3 4 3 2 1))" "(remove #(< % 3) '(1 2 3 4 3 2 1))" "(distinct '(1 2 3 4 3 2 1))" ]) Then it goes through *exprs-to-test*, evaluates them all, and prints the output like this: (doseq [exstr *exprs-to-test*] (do (println "===" (first (read-string exstr)) "=========================") (println "Code: " exstr) (println "Eval: " (eval (read-string exstr))) ) ) The above code is all working fine. However, (read-string exstr) is repeated so I tried to use let to eliminate the repetition like so: (doseq [exstr *exprs-to-test*] (let [ex (read-string exstr)] ( (do (println "===" (first ex) "=========================") (println "Code: " exstr) (println "Eval: " (eval ex)) ) )) ) But this works once for the first item in *exprs-to-test*, then crashes with a NullPointerException. Why is the addition of let causing the crash?

• C++ - defining static const integer members in class definition

  - by HighCommander4

  My understanding is that C++ allows static const members to be defined inside a class so long as it's an integer type. Why, then, does the following code give me a linker error? #include <algorithm> #include <iostream> class test { public: static const int N = 10; }; int main() { std::cout << test::N << "\n"; std::min(9, test::N); } The error I get is: test.cpp:(.text+0x130): undefined reference to `test::N' collect2: ld returned 1 exit status Interestingly, if I comment out the call to std::min, the code compiles and links just fine (even though test::N is also referenced on the previous line). Any idea as to what's going on? My compiler is gcc 4.4 on Linux.

• How can I know when SQL Full Text Index Population is finished?

  - by GarethOwen

  We are writing unit tests for our ASP.NET application that run against a test SQL Server database. That is, the ClassInitialize method creates a new database with test data, and the ClassCleanup deletes the database. We do this by running .bat scripts from code. The classes under test are given a connection string that connects to the unit test database rather than a production database. Our problem is, that the database contains a full text index, which needs to be fully populated with the test data in order for our tests to run as expected. As far as I can tell, the fulltext index is always populated in the background. I would like to be able to either: Create the full text index, fully populated, with a synchronous (transact-SQL?) statement, or Find out when the fulltext population is finished, is there a callback option, or can I ask repeatedly? My current solution is to force a delay at the end the class initialize method - 5 seconds seems to work - because I can't find anything in the documentation.

• how to interpret testng console log message for passing tests?

  - by Kunal Cholera

  I ran testng tests for my test classes, I get the following three types of log output when I run the passing tests. I am using org.testng.AssertJUnit.assertTrue() methods in my tests. [testng] PASSED: testMethod1 on null(test.foo.bar.Class1) [testng] PASSED: testMethod2 on Default test name(test.foo.bar.jar.Class2) [testng] PASSED: testMethod3 Can any one please tell me why for some tests it says "on null" for some it says "on Default test name ... " and for some it does not say anything on the console output. Specifically I want to make it consistent message. Environment : linux Testng framework : 6.3.2beta please advise. thanks.

• C++ Scoping and ambiguity in constructor overloads

  - by loarabia

  I've tried the following code snippet in 3 different compilers (G++, clang++, CL.exe) and they all report to me that they cannot disambiguate the overloaded constructors. Now, I know how I could modify the call to the constructor to make it pick one or the other (either make explicit that the second argument is a unsigned literal value or explicitly cast it). However, I'm curious why the compiler would be attempting to choose between constructors in the first place given that one of the constructors is private and the call to the constructor is happening in the main function which should be outside the class's scope. Can anyone enlighten me? class Test { private: Test(unsigned int a, unsigned int *b) { } public: Test(unsigned int a, unsigned int b) { } }; int main() { Test t1 = Test(1,0); // compiler is confused }

• Ruby Metaprogramming

  - by Veerendra Manikonda

  I am having a method which returns the price of a given symbol and i am writing a test for that method. This is my test def setup @asset = NetAssetValue.new end def test_retrieve_price_for_symbol_YHOO assert_equal(33.987, @asset.retrieve_price_for_a_symbol('YHOO')) end def test_retrive_price_for_YHOO def self.retrieve_price_for_a_symbol(symbol) 33.77 end assert_equal(33.97, @asset.retrieve_price_for_a_symbol('YHOO')) end This is my method. def retrieve_price_for_a_symbol(symbol) symbol_price = { "YHOO" => 33.987, "UPS" => 35.345, "T" => 80.90 } raise Exception if(symbol_price[symbol].nil?) symbol_price[symbol] end I am trying to mock the retrieve_price_for_a_symbol method by writing same method in test class but when i call it, the call is happening to method in main class not in the test class. How do I add that method to meta class from test and how do i call it? Please help.

• Unit Testing Example, on a class with required fields?

  - by Mastro

  I'm new to developing Unit test and I can't find an example of how to test an existing class I have. The class has a save method which does an insert or update in the database when the user clicks Save in the UI. But the save method has required fields that need to be populated. And has other fields that do not. So how can I run this test properly? Was trying to write it out.. Give a user When user saves object Then Field1 is required then Field2 is required Then Field3 is required WhenUserSavesObject() object = new object object.field1 IsNot Nothing something like that right? And what about the other fields that are optional? How would I test the save method to make sure it takes all those values properly? Was trying to use BDD but not sure if I should try it or not. Can't find any example of classes with many properties that are needed when calling a test method.

• Best way to make an attribute always an array?

  - by Shadowfirebird

  I'm using my MOO project to teach myself Test Driven Design, and it's taking me interesting places. For example, I wrote a test that said an attribute on a particular object should always return an array, so -- t = Thing.new("test") p t.names #-> ["test"] t.names = nil p t.names #-> [] The code I have for this is okay, but it doesn't seem terribly ruby to me: class Thing def initialize(names) self.names = names end def names=(n) n = [] if n.nil? n = [n] unless n.instance_of?(Array) @names = n end attr_reader :names end Is there a more elegant, Ruby-ish way of doing this? (NB: if anyone wants to tell me why this is a dumb test to write, that would be interesting too...)
