C++ 运行Qt单元测试

看看，因为我不想为我要测试的每个类创建一个单独的项目，所以我产生了以下代码：

testqstring.h

#ifndef TESTQSTRING_H
#define TESTQSTRING_H

#include <QtTest/QTest>

class TestQString : public QObject
{
    Q_OBJECT

private slots:
    void toUpper();
};

#endif // TESTQSTRING_H

但是，我收到以下链接器错误：

...
g++ -headerpad_max_install_names -arch i386 -o tester main.o testqstring.o moc_testqstring.o -F/Library/Frameworks -L/Library/Frameworks -framework QtCore 
Undefined symbols: 
"QTest::qExec(QObject*, int, char**)", referenced from: 
_main in main.o 
"QTest::compare_helper(bool, char const*, char*, char*, char const*, char const*, char const*, int)", referenced from: 
bool QTest::qCompare<QString>(QString const&, QString const&, char const*, char const*, char const*, int)in testqstring.o 
... and more like that ...

。。。
g++-headerpad_max_install_name-arch i386-o tester main.o testqstring.o moc_testqstring.o-F/Library/Frameworks-L/Library/Frameworks-framework QtCore
未定义的符号：
“QTest:：qExec（QObject*，int，char**）”，引用自：
_主音中的主音
“QTest:：compare_helper（bool，char const*，char*，char*，char const*，char const*，char const*，int）”，引用自：
boolqtest:：testqstring.o中的qCompare（QString常量&，QString常量&，char常量*，char常量*，char常量*，int）
... 更像这样。。。

我做错了什么？

添加：

CONFIG += qtestlib

将qmake链接到qtest库中的.pro文件。

您不需要链接到qtest吗？@Noah这是什么意思？还是现在的“QT+=testlib”
