C++ :: How To Write Boost Unit Test In Visual Studio 2010
Apr 16, 2014
I'm new to c++ and boost library also. I need to test a function of my library. For example
// Functions.hpp
int add(const int x, const int y);
//Functions.cpp
int add(const int x, const int y)
{
return (x + y);
}
Now i need to test add function using boost. I need the result or output in below style. What all settings do i need to do in VS 2010 and how i should include boost test in the project.
==== Run unit tests ====
Running 2 test cases...
./mytest.cpp(13): error in "SimpleTestInMainTestingModule": check 1 == 2 failed
Test suite "Master Test Suite" failed with:
1 assertion out of 2 passed
1 assertion out of 2 failed
1 test case out of 2 passed
1 test case out of 2 failed

I am running a unit test on a library and this line keeps failing on Fedora 16, G++ 4.6.2
Code:
assertNAN(double, std::numeric_limits<double>::signaling_NaN()); //sanity check
The assert looks like this
Code:
//needs to copy it so that if its a function call it only does it once
#define assertNAN(type, one) {
type val = (type)one;
std::string lag(#one);
lag += " not a number";
[Code] ...
I am compiling with -DNDEBUG -O3 -ffast-math -fexpensive-optimizations to simulate a production environment. Is there a way to test for NAN consistently?

I have function that returns historical data. I can access it, using file name. If I use file name, it reads that file and saves it to dictionary, so that in the future, if historical data is required for the same file, it does not read it again (it's lazy loading). If no file is supplied to the function, it tries to read file which is given in app settings.
However, for unit testing, I do not want to read any file. Instead, I want it to use small sample of hardcoded historical data. In order to do that, I think, I need to introduce interface to it. Then I can use some IoC to choose between different implementation for unit testing purpose and ordinary launch of application.
Function to get history is given as follows:
public static class Auxiliary
{
private static Dictionary<string, MyData> _myData;
public static MyData GetData(string fileName = null)
{
// ...
}
}
I have created default Unit Test project with Visual Studio so, as far as I know, by default it uses MSTest as test runner and MSUnit as unit testing framework but it does not have any IoC container so I should manage NuGet packages for solution and install Unity.
As far as I know, MSUnit (aka Moles) can unit test static methods (it's unconstrained isolation framework, like Typemock Isolator, unlike NUnit) but still many people suggest not to use any static methods for unit testing.
Should I use shim or stub [URL] Stubs should be used for faking external dependencies and here it is not external library, but my own code.

I am trying to write a unit convertor for converting temperatures Celsius, Kelvin and Fahrenheit.
Code:
if (select_one == 't' || select_one == 'T'){// this one works perfectly...
//This section does not tell you the use of variables.
//The use of variables can be seen as comments in the main program
[Code].....
This part of code will be part of a larger Unit Converter program. Do you think this method of conversion is wise? The error codes are for debugging use only.
I convert all temperatures of all units, whether Celsius, Kelvin or Farhenheit into Celsius and then convert it into the units the user wants.
For example:
Kelvin -----> Celsius ------------------> Farhenheit
(Input) (base of conversion) (desired output unit)
Do you think this type of conversion is okay?

I'm trying to write a program that uses the Boost library to input a string date in the format mm/dd/year and outputs to the string its corresponding day of the week. I wrote the program that I thought would accomplish this, but it doesn't seem to work. Below is the code I wrote:
#include <string>
#include <iostream>
#include "boost/date_time/gregorian/gregorian.hpp"
[Code]....
When I compile this using codeblocks it gives me the error "In function `ZN5boost9date_time19month_str_to_ushortINS_9gregorian10greg_monthEEEtRKSs':|
C:Users
osaDesktop est3........Liboost_1_55_0oostdate_timedate_parsing.hpp|67|undefined reference to `boost::gregorian::greg_month::get_month_map_ptr()'". And it takes me to the file date_parsing.hpp and highlights line 67. I don't understand why this isn't working.

How can we build unit-tests for functions of libraries, those with user-defined types used as their arguments ?
For example
CRecord func(Myclass * class, BSTR * name, CComptr<xxx> & something);

The project is about reading data from PIC and display the data on the dialogue created by the MFC GUI of Visual studio 2010. There are 4 data need to be displayed (2 weight and 2 angle). the data will be display on the edit control box on the dialogue.
I have try to solve the COMPort and Readdata issues many times, but I'm fail. I have read many sources and implement the source codes... They are never work....
The detail about the issues that I need to solve is clearly mentioned on the main dialogue.cpp. Take a look to an uploaded zip file that I have attached.

I heard that you can't use it with express, but that doesn't seem right... Can you use it with Codeblocks, at least? I just hate the Qt Creator IDE. I don't like the UI... all I want to do is code Qt. I don't care much for the GUI editors.

I wrote a routine in one C++ file and I decided to break it up into some smaller more manageable C++ files. When I copied the variables out of the first one and into the new smaller file (same solution), everything compiles fine but I get a ton of linker errors saying the variables have already been defined in another (the previous) file. Using Visual Studio 2008.

How to create/use a graphical interface. Especially since Microsoft has removed Windows Form Application support from Visual Studio 2012 and 2013.
I know that Windows Form Application is still supported with C#, but C# is definitely not an option as the program I am developing is heavily depended on some of C++'s more advanced features not present in C#.
Is there an alternative to Windows Form Application? I would definitely prefer one, as I doubt that some workarounds would work for long. What are common ways to create a GUI application in C++? There certainly must be some ways. In Java one would use something like JFrame.
Crossplattformcompatibility: The program I am creating is a Microsoft Windows program only. So I don't care if it runs on Linux or Mac. It only has to run from Windows 7 onward. So if there are more than one standard ways to create a GUI, I would prefer the one working best for Windows.
By the way, I am using Visual Studio 2013.

I want to have a multi user chat over TCP/IP. I already have the code for both the server and the client and so far I am able to send messages from the client to the server. Now I want to make it a multi user chat. I am executing the codes using Visual studio's Command prompt(not Windows Command Prompt). I have read somewhere that we have to use select() function.

i have written an algorithm in VC++ 2010 express edition. i have used the following header files
#include<iostream>
#include<string>
#include<sstream>
#include<ctime>
#include<cassert>
#include<fstream>
#include<vector>
[Code]...
the algorithm worked fine in vc 2010 express edition....
the following header files are not working in vc5
#include<regex>
#include<tuple>
#include<numeric>
#include<unordered_set>
#include "clip.h"
Looks like some of hte boost libraries have to added with vc5.. If any one knows how to add boost libraries with vc5.
showing lot of errors in vc5... not able to run the algorithm in vc5. Our company has only vc5.... the algorithm has to be implemented in vc 2010....

I stumbled upon an unexpected difference between GCC and VisualStudio: Different overloaded functions are called in the following example:
// -------- can assume this is located in 'tool.h' file --------------
// Fwd declaration support foo( const int& ) gets called as expected by both compilers
// void foo( const int& n );
template< typename T >
void foo( const T& n ) {
[Code] ....
What happens: I expected that by calling bar(1) compiler will notice both versions of foo() and call the best match, in this case foo(const int&). That is not the case.
Note that overloaded foo(const int&) is below bar(). It seems that at that point GCC does not see overloaded version, and happily calls template version. Visual studio on the other hand has no problem finding them both.
If I introduce a forward declaration of foo( const int& ) before bar(), both compilers call that version correctly. Unfortunately, that is not a solution for my problem here.
Template version is part of a library while overloaded is part of the user code. Both would be located in different (header) files and I would not like to impose #include order to the users or to be dependant on it.

So I am using Visual Studio 2012 Professional, this is C++ code. I am just trying to get the remainder from a very simple division. Nothing difficult, heres the code:
double getProbability(){
int rd = random();
int max = numeric_limits<int>::max();
double result = rd % max;
cout << "Probability: " << result << "
";
return result;
}
When I look at the values in debug I get:
max 2147483647
rd 1804289383
result 1804289383.0000000
That is completely wrong. The answer should be 0.840188. What is going on here?
random() just returns a number from a vector that was prepopulated with "random" integers. Not really random, but that isn't all that important. What is important is why on earth is a % operation returning such a huge number. I assigned the values to variables so I could look at them in the debugger. I know I am going to probably get a thousand different ways that I could do this "better" but again, that isn't what I am looking for. I would just like to know why the % operation is doing what it is doing?

I have a project that is essentially a hot pot of C/asm (naked functions etc). The code gets injected into another EXE. It works fine when compiled in Visual C++ 6 but when compiled in Visual Studio 2008 it compiles fine but falls over in use.
Are there certain settings I need to look out for? I have optimization disabled and as far as I can tell the command line options for compiler/linker are the same (given the differences).
I have opened both builds in IDA and the 2008 build has more import and offset jumps are in different places.

I downloaded Visual Studio 2013 on a new laptop. On my old one I could press things like ctrl + F7 to compile and ctrl + F5 to start without debugging however now it isn't responding when I type those commands. Nothing happens at all. How to change this? I googled "keyboard shortcuts not working in Visual Studio 2013" but per the usual Google comes up with garbage search results that do not pertain at all.
