Divide a QTest into implementation and header file

FredJupiter

Hi all,

I've a very simple question: I want to divide a test into an implementation and header file like this:

#include "tst_simpletest.hpp"

void simpleTest::test_case1()
{

}

QTEST_APPLESS_MAIN(simpleTest)

#include "tst_simpletest.moc"

#ifndef TST_SIMPLETEST_HPP
#define TST_SIMPLETEST_HPP

#include <QtTest>

// add necessary includes here

class simpleTest : public QObject
{
    Q_OBJECT

public:

private slots:
    void test_case1();

};

#endif // TST_SIMPLETEST_HPP

cmake_minimum_required(VERSION 3.5)

project(simpleTest LANGUAGES CXX)

enable_testing()

find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Test)
find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Test)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

add_executable(simpleTest tst_simpletest.cpp
    tst_simpletest.hpp)
add_test(NAME simpleTest COMMAND simpleTest)

target_link_libraries(simpleTest PRIVATE Qt${QT_VERSION_MAJOR}::Test)

Quite simple but I got a warning during compilation:

[1/4 0.4/sec] Automatic MOC and UIC for target simpleTest
AutoMoc warning
---------------
"SRC:/tst_simpletest.cpp"
includes the moc file "tst_simpletest.moc", but does not contain a Q_OBJECT, Q_GADGET, Q_GADGET_EXPORT, Q_NAMESPACE or Q_NAMESPACE_EXPORT macro.

AutoMoc: /home/mario/qtTestTest/tst_simpletest.cpp:0:1: note: No relevant classes found. No output generated.

[4/4 0.5/sec] Linking CXX executable simpleTest
09:14:06: The process "/usr/bin/cmake" exited normally.
09:14:06: Elapsed time: 00:08.

How can I fix this warning?

I can remove the moc include and the build is successful, the test ist running but isn't the content of the moc file missing? Or is this inlcude remnant of qmake and done with the CMAKE_AUTOMOC step?

You don't need the moc include because you now have a header where cmake can find the class declaration and can create the moc file automatically
