Qt 5.2无法使qWait函数工作

Question

我有一个包含以下内容的头文件：

#include <QtTest/QtTest>

我正在尝试使用以下行在我的主窗口中生成非阻塞等待：

QTest::qWait(1000 - ui->speedDial->value());

我收到以下错误：

mainwindow.obj:-1:错误：LNK2019：未解析的外部符号"__declspec（dllimport）void __cdecl QTest:：qSleep（int）"（__imp_？qSleep@QTest@@YAXH@Z)在函数"void __cdecl QTest:：qWait（int）"中引用（？qWait@QTest@@YAXH@Z)

有人能帮助我理解我做错了什么，或者提供一种替代方法吗？这些行独立于其他代码。

它对我来说很好。查看这个例子，它是Qt Test官方文档的修改版本示例：

教程1.pro:

SOURCES = testqstring.cpp
CONFIG  += qtestlib
# install
target.path = $$[QT_INSTALL_EXAMPLES]/qtestlib/tutorial1
sources.files = $$SOURCES *.pro
sources.path = $$[QT_INSTALL_EXAMPLES]/qtestlib/tutorial1
INSTALLS += target sources
symbian {
    TARGET.UID3 = 0xA000C60B
    include($$QT_SOURCE_TREE/examples/symbianpkgrules.pri)
}
maemo5: include($$QT_SOURCE_TREE/examples/maemo5pkgrules.pri)
symbian: warning(This example might not fully work on Symbian platform)
maemo5: warning(This example might not fully work on Maemo platform)
simulator: warning(This example might not fully work on Simulator platform)

testqstring.cpp：

#include <QtTest/QtTest>
#include <QDebug>
class TestQString: public QObject
{
    Q_OBJECT
private slots:
    void toUpper();
};
void TestQString::toUpper()
{
    QString str = "Hello";
    QTest::qWait(2000);
    QCOMPARE(str.toUpper(), QString("HELLO"));
}
QTEST_MAIN(TestQString)
#include "testqstring.moc"
