How to compose multiple unit test result in a single txt file - qt

Question

I am using QTestLib Library and QTest for running my unit tests. I am working on windows 7 and using Qt 4.8 When I run my test using:
int main(int argc, char *argv[])
{
// Test gui widgets - 2 Spinboxes and 1 Combobox
QApplication a(argc, argv);
TestSpinBox testSpinBoxObj;
TestComboBox testComboBoxObj;
QTest::qExec(&testComboBoxObj, argc,argv);
QTest::qExec(&testSpinBoxObj, argc,argv);
return 0;
}
I get the output in the console:
Starting D:\Projects\Qt Learning\TestGui (1)\TestGui\debug\TestGui.exe...
********* Start testing of TestComboBox *********
Config: Using QTest library 4.8.1, Qt 4.8.1

How to get the same in a single text file

Answer 1

There is -o filename option to specify output file. For each test object you can redirect output to own file and later concatenate them together.
QList<QObject *> objects;
objects << new TestSpinBox << new TestComboBox;
QString result;
foreach (QObject *o, objects) {
QTemporaryFile f;
f.open();
QStringList args = app.arguments();
args << "-o" << f.fileName();
QTest::qExec(o, args);
result += "\r\n" + f.readAll();
}
qDeleteAll(objects);
