QT Project Build Issue

ayush_mistral

Hi,

I added cppunit testing framework to test a QT GUI Application. After Adding application project is not building. It is showing undefined errors for Qt components like Qdebug, QPainter etc. If I remove cppunit testing library and Cppunit Macros for testing in the source code of the project, it is building and running fine. Please tell me if anyone has any idea about this issue.

Thanks in advance
Ayush

You should provide more information: how did you add cppunit library, what did you change, what are the error messages exactly.
Can you post your PRO file?

Qt provides a test framework: http://doc.qt.io/qt-5/qtest-overview.html

I added the cpp unit library with add external library wizard of the QT creater, provide the library path and include path of the headers.

I added the CppUnit Macros in the source code to test one of the methods of class like this
class sampletest : public CppUnit ::TestCase
{
CPPUNIT_TEST_SUITE(sampletest);
CPPUNIT_TEST(zerotest);
CPPUNIT_TEST(nonzerotest);
CPPUNIT_TEST_SUITE_END();

public:
void zerotest();
void nonzerotest ();
};

void sampletest :: zerotest()
{
MfcCoreConfig mysample;
CPPUNIT_ASSERT_MESSAGE ("Test Failed", mysample.validateThresholdValue(11.01f) == MAX_MFC_THRESHOLD);

}

void sampletest :: nonzerotest()
{
MfcCoreConfig mysample;
CPPUNIT_ASSERT_MESSAGE ("Test Not Passed", mysample.validateThresholdValue(100.01f) == MAX_MFC_THRESHOLD);
}
