Split the implementation of a single Qt Test class into multiple .cpp files

Mrts

Hello!

I understand that dividing a Qt Test into multiple classes is a bit tedious and ways of doing it have been discussed before.

I'm OK with a single Qt Test class, but I would like to split the implementation into multiple .cpp files, like this:

tests
├── tests.pro
├── main.cpp <-- main imports the header and has QTEST_GUILESS_MAIN(MyAppTests)
├── my-app-tests.hpp <-- a single class MyAppTest is declared here
├── my-app-tests-test1.cpp <-- here is the implementation of MyAppTest.test1()
└── my-app-tests-test1.cpp <-- here is the implementation of MyAppTest.test2()

However, when I do this, building the project with make breaks:

No rule to make target 'main.moc', needed by 'main.o'. Stop.

Indeed, when I look into Makefile, I don't see any moc targets created.

How can I fix this?

Note that everything works well if the declarations and definitions are in main.cpp.

main.cpp

#include "my-app-tests.hpp"

QTEST_GUILESS_MAIN(MyAppTests)

#include "main.moc"

my-app-tests.hpp

#include <QtTest>

class MyAppTests : public QObject
{
    Q_OBJECT

private slots:
    void test1();
    void test2();
};

tests.pro

TARGET = my-app-tests
TEMPLATE = app

CONFIG += testcase

QT     += testlib

HEADERS += \
    my-app-tests.hpp

SOURCES += \
    main.cpp \
    my-app-tests-test1.cpp \
    my-app-tests-test2.cpp

my-app-tests-test1.cpp

#include "my-app-tests.hpp"

void MyAppTests::test1()
{
      QCOMPARE(1, 1);
}

Hi,

There's not QObject defined any your main.cpp file anymore, therefore the #include "main.moc" line won't work anymore.

@SGaist Thanks! Right, so it seems to be better to live with the limitation and keep the implementation in main.cpp.
