CUTI stands for C++ Unit Test Integrated

CUTI allows you to easily integrate your C++ unit tests into Visual Studio and Xcode. It is also possible to use cppunit's macros and test runner through compatibility configuration.

• You can run your tests from within your IDE
• You have visual feedback when running your tests
• It is easier to use your IDE tools with your tests like code coverage, profiling,...
• It is easier to debug your code
• You are more likely to run your tests

• Use CMake >= 3.2
• The code to test must be compiled as a library (static or shared)

• Add CUTI's root directory to your CMakeLists.txt

add_subdirectory(${PATH_TO_CUTI_ROOT_DIR} ${CMAKE_BINARY_DIR}/cuti)

• Create a test target

cuti_creates_test_target(test_project_name project_to_test list_of_test_files_cpp)

• That's it! Take a look at ./test/testDynamicLib/CMakeLists.txt for an example

There is a toy project in the test directory to show how to use Cuti.

add_subdirectory(${PATH_TO_CUTI_ROOT_DIR} ${CMAKE_BINARY_DIR}/cuti)
#create your library (SHARED or STATIC)
add_library(MyLib SHARED ${MyLib_source_files})
#Create 'MyLibTest' test target to test MyLib
cuti_creates_test_target(MyLibTest MyLib ${MyLibTest_source_files})

#include "Cuti.h"

TEST_CLASS(TestClass) {
public:
    /**
    * Optional. Executed before every test case
    */
    SET_UP() {
      //...
    }

    /**
    * Optional. Executed after every test case
    */
    TEAR_DOWN() {
        //...
    }

    void testSimpleAssert() {
        ASSERT(true);
    }
    /**
     * Test suit declaration and test case registration
     */
    BEGIN_TESTS_REGISTRATION(TestClass);
    TEST(testSimpleAssert);
    END_TESTS_REGISTRATION();//must be the last statement in the class
};

By default, CUTI's creates a test target for its front end and Xcode or Visual Studio unit test framework. This behavior can be customized for compatibility.

• CUTI_FRONT_END can be set to CUTI or CPPUNIT
  • CUTI: use macros starting by CUTI_
  • CPPUNIT: allow to use macros starting by CPPUNIT_. Useful if your codebase was using cppunit and you don't want to re-write everything.
• CUTI_BACK_END can be set to CUTI or CPPUNIT
  • CUTI: use Xcode or Visual Studio unit test framework as test runner
  • CPPUNIT: use cppunit as test runner. Useful if you want to run your unit tests on a platform not supported by Xcode and Visual Studio.

Templates are available in the test directory

• TemplateFreeStanding.cpp : Shows how to write a test class when using CUTI_FRONT_END=CUTI
• TestTemplate.cpp : Shows how to write a test class when using CUTI_FRONT_END=CPPUNIT

Issues and merge requests are welcome !

• "Message: A 64-bit test cannot run in a 32-bit process. Specify platform as X64 to force test run in X64 mode on X64 machine."
  • By default Visual Studio tries to run the unit tests target with a 32 bits test runner. But if you are compiling in 64 bits this will fail. To fix this go to: Test -> Test Settings -> Default Processor Architecture -> X64

• No test case in my test suite
  • Xcode only show test cases starting by "test". To fix either rename your test case or define CUTI_PREPEND_TEST. Take a look at TestLibInt.cpp for an example.
