QUESTION
I try to set up a test project in Visual Studio 2019.
The module that I want to test is written in c.
I'm using the native VS cpp Testframework.
I can compile and run my program but not my unittest. Once I try to run that one I get the following error:
Fehler LNK2019 Verweis auf nicht aufgelöstes externes Symbol "_is_prime" in Funktion ""public: void __thiscall UnitTest1::UnitTest1::TestMethod1(void)" (?TestMethod1@UnitTest1@1@QAEXXZ)". UnitTest1 C:\Users\Alexander Leibenath\Documents\20210210_Prime_VS\Primzahlprüfer\Primzahlprüfer\UnitTest1\UnitTest1.obj 1
What I've tried so far:
- told the comiler in the header file that if he is a cpp compiler he should interpret the c-functions as c
Here is my code:

I have a std::string declared in my TEST_CLASS that should be initialized once for the class that is to be used in two other TEST_METHODs.
However, when TEST_CLASS_INITIALIZE is called (which does run before any TEST_METHOD), projectDirectory is properly set. Yet, the issue is that when I debug what the value is of projectDirectory in each TEST_METHOD, the value is an empty string ("").
What am I doing incorrectly?
...ANSWER
Answered 2021-Feb-16 at 15:09There are at least a couple of issues with your example code.
You are declaring a local variable
projectDirectoryin theTEST_CLASS_INITIALIZE, which hides the class memberprojectDirectory.TEST_CLASS_INITIALIZEcannot be used to initialize class members (unless they are declared as static). You should useTEST_METHOD_INITIALIZEfor this.

I am having a problem with Visual Studio 2019 CPPUnitTestFramework. I follow the instructions, but every time I get an error. I have looked for tutorials, but anything I get is for Visual Studio 2017 and it does not solve my problem.
I am writing a program that uses OOP in C++ and I want to make unit tests, since it is going to be a considerably long project. The problem that I am having is that the program is not compiling in the test module.
Consider that I have the code such that I have the header file:

Right now i'm busy writing an event based queue. I wanted to do some unit testing but i'm running into an error. In Microsoft Visual Studio, when making a unit test project, you have to implement this function for each type you do an assert on:

QUESTION
Unit testing means writing code that verifies individual parts, or units, of an application or library. A unit is the smallest testable part of an application. Unit tests assess code in isolation. In C++ this means writing tests for methods or functions. I am writing a basic calculator program and trying to use CPPUnitTest to test the code in Visual studio 2019.After that I have to build this in Jenkins too. Please don't judge .. I am writing unit Test for the 1st time .. this is my Calculator.cpp

Answered 2020-Mar-03 at 12:48You should not use assert::AreEqual when checking for exceptions.
You could wrap your exception throwing code in a lambda and pass it to Assert::ExpectException, which should assert true if the expected exception is thrown:
QUESTION
TL;DR: You can use GMock to add mocking capability to your Microsoft native c++ unit tests. See my answer below for details.
I want to start adding mocks to my existing set of native unit tests. The tests are written using Microsoft's CppUnitTestFramework framework, which doesn't have support for mocking. I don't really want to convert the entire test suite to another framework just to add a few mocks.
Google's GMock framework seems to provide everything I need and the documentation suggests it can be used with frameworks other than gtest. So using advice from blog posts like this one, I created a couple of unit tests.
ANSWER
Answered 2020-Mar-01 at 22:35I was able to get GMock working correctly with the CppUnitTestFramework by creating a custom TestEventListener. I then created a simple set of interface functions to make it easier to work with.
I used the gmock 1.7.0 NuGet package to install the GMock framework into my project, and added the two files shown below.

QUESTION
I am implementing some unit test using cpp unit test framework for visual studio. I want to be able to compare enums in the test but there is always an error that keeps showing up.
This is the code that causes me the error.
...ANSWER
Answered 2020-Feb-07 at 17:06I have never used microsoft cpp unit tests, but from the error message and experience with gtests I think you have to add a method ToString for your enum class. (My guess is) It is because if the Assert fails, both arguments are printed to some output using ToString method.
At the end of this article similar problem is solved.
QUESTION
I am primarily a Linux developer however, I have inherited a windows dll with a memory leak. I know the cause and believe I have fixed it. I would like to check this in the unit tests. The unit tests use the builtin cppunit test framework, which is no relation to the cppunit framework I normally use on Linux. i.e.
...ANSWER
Answered 2019-Dec-19 at 13:46I don't feel that trying to use the OS API's is reliable, as if I do p = new char[1024]; delete[] p; there is no promise that memory is returned to the OS, and in many cases it won't be. e.g. say the smallest page size is 4KB, well obviously handing out 4KB for small objects would be wasteful, so the allocator inside your process will split this larger chunks up, and thus the OS can't see if such pieces are freed or not.
The applies to other OS/compilers as well. You can determine a trend over time if you keep repeating the same test loop "it keeps using more memory", but then you have to go searching for it, and with less-consistent loads, hard to tell if a few KB difference is a leak or not.
Visual Studio has a number of more integrated tools to help. These generally assume you are using new/delete, malloc/free, or other such things the IDE could potentially know about. If you are not, you might need to adjust your DLL slightly so it is possible for the IDE to know what is going on in the most accurate way.
If for example you use an internal memory "pool", the system can only know that the pool allocated memory, not what it was used for or if it was returned to that pool.
To find a memory leak within an execution (say running a test case), you can use the memory leak detection feature.
QUESTION
I have a bunch tests for a project which were originally written using Gtest, but I have since moved them into Microsoft's CppUnitTestFramework. In order to prevent having to rewrite all my tests, I made macros which follows how GTest does its tests -- for example, EXPECT_EQ.
Now, I am trying to eliminate all warnings generated by MsBuild, including those by the Code Analysis, which relate to using constexpr if available. In the tests, there's quite a few of these, since the expected value is usually a literal, although not always. So I have my own EXPECT_EQ which is as follows:

Install CppUnitTestFramework
Create an entry-point file with the following contents to generate a main function: #define GENERATE_UNIT_TEST_MAIN #include "CppUnitTestFramework.hpp"
Create individual .cpp files for your test fixtures and use the TEST_CASE() macro to create individual test cases: #include "CppUnitTestFramework.hpp" namespace { struct MyFixture { ... }; } TEST_CASE(MyFixture, Test1) { ... } TEST_CASE(MyFixture, Test2) { ... }
Compile your program and run.
