[Solved] How to get the list of test cases in a test class- Unit Testing.

[Sam]

Inorder to perform unit testing for an application we declare many test cases/functions under the private slots. Is there any way to get the list of test cases/functions for a unit test class based on the class name ?

eg :-

@class TestDateEdit : public QObject
{
Q_OBJECT
private slots:
void testChanges();
void testValidator_data();
void testValidator();

};@

So from the above class how to get the test cases/functions that will run like testChanges() and testValidator().

By using like this u can get the test cases/functions, i think

@
void TestDateEdit::testChanges()
@
Whether it will work.

No you didnt get my question , the above answer that u suggested is for the implementation/definition of the testFunction , I need to get the list/stringlist of the valid test cases/function for a test class based on the className.

Because TestDateEdit is subclass of QObject you can use metaObject(). There you can use methodCount() and method() for more informations.

Something like

@const QMetaObject* metaObject = obj->metaObject();
QStringList methods;
for(int i = metaObject->methodOffset(); i < metaObject->methodCount(); ++i)
methods << QString::fromLatin1(metaObject->method(i).signature());@

from the documentation of QMetaObject::methodCount() ?

Hello Sam,

this should work.
You can restrict this to the private slots with
@access() == Private && methodType() == Slot@

Thanks for the reply,

How can I create an instance of a class from a QString ?

I looked at the documentation of QMetaType and got

@int id = QMetaType::type(testClass);
if (id == 0)
{
void *myClassPtr = QMetaType::construct(id);

}@

But how to create an instance , for eg i only have a QString "TestDate" ?

Edit : This issue is solved

Thanks a lot it works perfect :)

This is solved.

@
int i=0;
const QMetaObject *metaObject = object->metaObject();
QStringList methods;

for (int i= metaObject->methodOffset(); i < metaObject->methodCount(); i++)
{
if((metaObject->method(i).access() == QMetaMethod::Private) && (metaObject->method(i).methodType() == QMetaMethod::Slot))
methods << QString::fromLatin1(metaObject->method(i).signature());
}

/* To restrict the valid functions for display */
foreach (QString str, methods) {

if(str.endsWith("_data()"))
methods.removeAt(i);
i++;
}@

Hi,
I have another question. Is there any way to skip any particular test case/function while running the test using QTest::qExec(). The scenario is that i have listed the test functions in a treeView with checkbox as a QStandardItem, So foreach testClass the associated testFunctions are listed.

Now the requirement is to test only those cases/functions that are checked and the other's should be skipped.

I have tried

@testCmd<<" " << QString("%1").arg(childItem->text())<<"-xml" <<"-o" <<QString("UnitTest_Results/%1_log.xml").arg(className);

QTest::qExec(plugin->testList().at(pRow),testCmd);@

this generates an xml output but the xml.file is overwritten for each test function and at the end displays the result of the last checked item.

Thanks.
