单元测试问题QWidget: Must construct a QApplication before a QWidget

[dilipa]

我尝试QT 单元测试 使用教程例子 却遇到了问题

一个致命的问题QWidget: Must construct a QApplication before a QWidget

[jsulm]

@dilipa Please read documentation: https://doc.qt.io/qt-5/qtest.html#QTEST_APPLESS_MAIN
Especially this: "but doesn't instantiate a QApplication"...

@jsulm 我的问题得到了解决，非常感谢，但同时我想到在创建项目时，支持选择GUI，是否应该在选择的同时自动生成QTEST_MAIN（）而非QTEST_APPLESS_MAIN（）。

@dilipa I don't speak Chinese...

@jsulm Sorry, I didn't think about this, my problem has been solved, thank you very much, but at the same time I wonder if I should automatically generate QTEST_MAIN () instead of QTEST_APPLESS_MAIN () when creating projects that support GUI selection.

@dilipa said in 单元测试问题QWidget: Must construct a QApplication before a QWidget:

QTEST_MAIN () instead of QTEST_APPLESS_MAIN () when creating projects that support GUI selection

Yes, as soon as GUI is involved you can't use QTEST_APPLESS_MAIN
