CMake Build Type specified Building

[Kevin470]

I am learning how to run unit tests with Qt Test.
I see that it is possible to disable code from the main.cpp like below.

#include "mainwindow.hpp"
#include <QApplication>

#ifdef QT_DEBUG
    #include <QTest>
#endif

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
#ifdef QT_DEBUG
    QTest::qExec(&w);
#endif
    w.show();
    return a.exec();
}

Is it possible to specify what the CMake builds similarly?
For example, if I am building with the Debug Kit, then

find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Widgets Test)
find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Widgets Test)
target_link_libraries(WindowTest PRIVATE Qt${QT_VERSION_MAJOR}::Widgets Qt${QT_VERSION_MAJOR}::Test)

And for Release,

find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Widgets)
find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Widgets)
target_link_libraries(WindowTest PRIVATE Qt${QT_VERSION_MAJOR}::Widgets)

if (CMAKE_BUILD_TYPE MATCHES Debug)
   find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Widgets Test)
   find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Widgets Test)
   target_link_libraries(WindowTest PRIVATE Qt${QT_VERSION_MAJOR}::Widgets Qt${QT_VERSION_MAJOR}::Test)
else()
   find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Widgets)
   find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Widgets)
   target_link_libraries(WindowTest PRIVATE Qt${QT_VERSION_MAJOR}::Widgets)
endif()

Just as a note, you should run tests on release builds too.

Hi,

Don't mix your test code within your application code. Tests should be in a dedicated folder.

@SGaist @mchinand Thank you so much. Unit testing is a new concept for me and I am trying to learn how to do it and best practices.
