Self-turning blog: http://blog.csdn.net/zhu_xz/archive/2009/12/25/5076157.aspx The qtestlib framework provides an easy-to-use unit test framework. You need to add QT ++ = testlib to the project file. First read oneSimple Example: C/C ++ code # Include Class testqstring: Public qobject { Q_object Private slots: // Each private slot function is a test function automatically called. Void testtolower (); // The function ending with "_ DATA" provides test data to the corresponding test function. Voi

compilers, it is consistent with the Microsoft ABI under Windows, and in other platforms, with GCC.Use examples to speakWhat's an example? The amount ... Find a simple dynamic library and see the name of the function it derives from. QT's core and GUI modules are too complex, take the QT test module to see it, QtTest4.dll or libqttest.so.4.8.0How do you see the symbols? Under Windows, we can use the DUMPBIN tool: Dumpbin/exports Qttest4.dll On Linux, we can use NM or read

Why does QT not provide sleep? Someone asked me from time to time on the Forum: Why does QT not provide cross-platform sleep functions? Why didn't the interface respond after using platform-related sleep or nanosleep? Qthread provides the sleep function with the protected permission. How do I use it in the main thread? How can I hide the console in Windows by using qsleep in qtest? These problems actually come down to one point: using these func

class, write a testqstring. cpp file. #include Then, enable the testlib module in the Pro file. The others are the same as the common QT program. When cmake is used, we divide it into two files //testqstring.h #include And //testqstring.cpp void TestQString::toUpper() { QString str = "Hello"; QCOMPARE(str.toUpper(), QString("HELLO")); } QTEST_MAIN(TestQString) #include "testqstring.moc" Then the processing method is the macro we saw earlier.Qtest macro Take a look at the

PatchesWe think of old-prj.tar.bz2 as the Linux kernel, and when we unzip it, we go to the root folder of the code tree:$ mkdir qtest; CD qtest; Tar xvjf. /old-prj.tar.bz2; MV Old-prj PRJ; CD PRJWe usually have to make an official patch before we change the code.

process strategy.2.2 import Patches We think of the old-prj.tar.bz2 as the Linux kernel, We decompress it and enter the root directory of the code tree: $ Mkdir qtest; CD qtest; tar xvjf ../old-prj.tar.bz2; MV old-prj; CD prj Before modifying the code, we usually need to install official patches first. In quilt, you can use the import command to import the patch: $ Quilt import.../prj. Diff Importing patch

polymorphic. That is, polymorphism is the same message that makes different classes respond differently.There are three prerequisites for implementing polymorphism in Java: inheritance, rewriting, and upward transformation.Inheritance: Subclasses and parent classes that have inheritance relationships must exist in polymorphism.Rewrite: Subclasses redefine some methods in the parent class and call the methods of the subclasses when they are called.Upward transformation: In polymorphic, a referen

Using the sleep function in QT is difficult. This function is not available in several common header files. There is a sleep in the QTest class for unit testing. You can run the following command: # IncludeQTest> ....... QTest ::QSleep(100); In this way. In the help document, qSleep actually calls the sleep function provided by the operating system. For example, it calls nanosleep () on Linux and Sleep
