如何使用QAbstractItemModelTester与谷歌测试?

Question

我使用googletest作为Qt项目的主要测试框架。QAbstractItemModelTester有助于捕获自定义项目模型类中最常见的错误，但我不知道如何将报告的失败(QTest(集成到googletest单元测试中。

Answer 1

我没有找到任何直接的方法来做到这一点，但这是我为在 QAbstractItemModelTester 中测试错误所做的

断言：

class AssertNoQtLogWarnings
{
static void messageHandlerTest(QtMsgType type, const QMessageLogContext& context, const QString& msg)
{
static bool NO_WARNING_MSG = true;
QByteArray localMsg = msg.toLocal8Bit();
const char* file = context.file ? context.file : "";
const char* function = context.function ? context.function : "";
switch (type) {
case QtDebugMsg:
fprintf(stderr, "Debug: %s (%s:%u, %s)n", localMsg.constData(), file, context.line, function);
break;
case QtInfoMsg:
fprintf(stderr, "Info: %s (%s:%u, %s)n", localMsg.constData(), file, context.line, function);
break;
case QtWarningMsg:
EXPECT_EQ(false, NO_WARNING_MSG) << msg.toStdString();
break;
case QtCriticalMsg:
EXPECT_EQ(false, NO_WARNING_MSG) << msg.toStdString();
break;
case QtFatalMsg:
EXPECT_EQ(false, NO_WARNING_MSG) << msg.toStdString();
break;
}
}
public:
AssertNoQtLogWarnings()
{
qInstallMessageHandler(messageHandlerTest);
}
~AssertNoQtLogWarnings()
{
//Install default message handler
qInstallMessageHandler(nullptr);
}
};
TEST(QAbstractItemModel, QAbstractItemModel)
{
//RAII object. Any warning, critical or fatal message produced in this context
//will produce a GTest fail assertion
AssertNoQtLogWarnings logQtTest; 
MyAbstractItemModel model;
QAbstractItemModelTester tester(&model, QAbstractItemModelTester::FailureReportingMode::Warning);

}
