QTEST_APPLESS_MAIN macro bug

Gabriel_22

I created a new project by selecting New Project -> Other Project -> Auto Test Project

The file looked like this:

#include <QtTest>

// add necessary includes here

class MyClass : public QObject
{
    Q_OBJECT

public:
    MyClass ();
    ~MyClass ();

private slots:
    void test_case1();

};

MyClass::MyClass ()
{

}

MyClass::~MyClass ()
{

}

void MyClass::test_case1()
{

}

QTEST_APPLESS_MAIN(MyClass )

#include "tst_myclass.moc"

But there was an error in the line: QTEST_APPLESS_MAIN(MyClass)

*tst_delete.cpp:33:1: error: cannot initialize a parameter of type 'const char ' with an rvalue of type 'int'
qtest.h:345:5: note: expanded from macro 'QTEST_APPLESS_MAIN'
qtest.h:336:74: note: expanded from macro 'QTEST_SET_MAIN_SOURCE_PATH'
6:30: note: expanded from here
qtestcase.h:283:75: note: passing argument to parameter 'builddir' here

Why does this error exist right at the project creation?
Is there a way to fix it or avoid it?

I am using Qt Creator 4.9.0 and Qt 5.10.0

Hi @Gabriel_22,

I cannot reproduce your problem on Ubuntu 18.04 with Creator 4.9.0 and Qt 5.12.3.

Which operating system are you using? And which compiler?

Regards

Hello @aha_1980,
Im using windows 10 and mingw 32bits compiler

Please show use the compiler output - there must be QT_TESTCASE_BUILDDIR given as a define to the compiler afair.

The project compiled and ran normally, even with the error

@Gabriel_22 said in QTEST_APPLESS_MAIN macro bug:

Than it sounds like a false positive from the Clang Code Model ... can you test a newer Qt version like 5.13.x if the problem still appears? Then you could file a bug report for that issue.

Gabriel_22

I tried with Qt 5.13 and got the same error, but still compiling and running.
I will file a bug report for this issue as suggested.
