QTest GUI getting started
-
I am trying to figure out how to use QTest to test my gui application, so I set up a simple program like the one in this posting Qt test empty window. (Using Qt 5.7 on Ubuntu)
When I try to run it, I get the message tst_mytest.cpp:33: undefined reference to `MyMainWindow::MyMainWindow(QWidget)'*.
This should be really simple but I can't figure out what it is.
Thanks,

MyMainWindow_ = new MyMainWindow;
I should have said the error occurs on the line on the line
MyMainWindow_ = new MyMainWindow; -

undefined reference to `MyMainWindow::MyMainWindow(QWidget)'*.
It says it dont know your constructor.
I would completely delete the build folder, and run qmake + rebuild all.
If error persists, please check that MyMainWindow.cpp is actual included into the .pro file
so it gets linked to the tst_mytest project. -
Hi,
In your test, you only build the test sources itself. What about the class you want to test ?

[EDIT: please ignore this post, it's irrelevant and wrong. Sorry!]
@jastmc
Since the example you quote uses:mainWindow_ = new MainWindow();why do you write
MyMainWindow_ = new MyMainWindow;and then ask why it doesn't behave same?

Whoops? For my own edification, does stinky C++ allow you to omit the
()innew Somethingand call a default constructor? parameterless constructor? complain if multiple constructors? or what?? -

yes the new operator/compiler can construct an object if it can find
a default constructor (ctor). The ctor is a special function and and that is why () can be omitted even one often consider it just a function call. -
@jsulm Thanks, that was part of it.
I then had to add
INCLUDEPATH += $$PWD/../MyApp/ \ ../../build-MySolution-Desktop_Qt_5_7_0_GCC_64bit-Debug/MyApp/ \to the MyTest.pro file because the next message was that it could not find the ui_mymainwindow.h file. So that solved it.

You are missing the
FORMSvariable in your .pro file.
