The tenth chapter of software testing, but also I personally prefer a direction, software testing, although not involved in the code of irritability, but also contains a lot of technology, below I give you a brief introduction to the contents of this chapter.In this chapter, we first cite a few cases, the history of software error events, let us recognize the importance of software testing. Next to the tester's quality requirements also do a detailed

Suddenly cooled down, and the grass was defrosted. The road is still the color of late autumn, and the tenth year of work has passed.----- Preface --------------------------I don't know from which year I got a lot of replies about persistence. I think about the past ten years. It's so fast and it's just too late to stick to it.In terms of technology, I have been able to complete the task from the very beginning to the present. Although it

NHibernate level cache (tenth article)NHibernate first-level cache, the noun seems to be very cow B, difficult. is actually the ISession cache. stored in the operating cycle of the ISession. The level two cache is stored in the isessionfactory.first, ISession level cache testISession first-level cache is turned on by default, no configuration is required. The ISession cache can be used after the ISession is created, and each time the data is manipulat

Tenth Chapter1. In the animation, because js efficiency is high, so the transition effect is not visible2. Off-topic: ① Foreign people write books, always first thanks to friends and family, finally thanks to their families.3. "Unless you allow users to ' freeze ' mobile content, you should avoid moving content around the page"4. Animations often encounter problems: moving the mouse back and forth, the animation will be a problem.Cause: Queue events a

The tenth chapter: generic algorithmNotes1. The standard library does not add a lot of functionality to each container, but rather provides a set of algorithms , most of which are independent of any particular container.2. Most algorithms are defined in the header file algorithm , and a set of numeric generic algorithms are defined in the header file numeric .3. Ensure that the algorithm has sufficient element space to open the output data by using an

Android Development Art Exploration-tenth chapter Android message mechanism reading notesHandler is not designed to update the UI, but is often used to update the UIOverviewAndroid's message mechanism is the main merit is handler operation mechanism, handler operation needs the bottom MessageQueue and looper support.

The tenth chapter describes the complex Linux drivers and HAL and other libraries, need to use a variety of methods to test it. Examples include setting breakpoints, stepping through code output debugging information, and so on. InLinuxin the system,/proc is often used as a tool for data interaction between the kernel space and the user space, and the/proc file system behaves like a device file system. /proc is a virtual file system, which means that/

PRINTKfunction Usage andprintffunction is similar, exceptPRINTKfunction runs in kernel space,printffunctions run in user space,PRINTKfunc

By learning Android Deep Exploration (Volume one) HAL and Driver Development chapter Tenth let me know the debugging technology and debugging tools for embedded Linux.PRINTK can print kernel debugging information, the function is similar to the printf function, except that the PRINTK function runs in kernel space, and the printf function runs in user space. The PRINTK file is a simple four-digit text file with a default value of: 6: Output The message

Tenth ChapterFor complex Linux drivers and libraries such as HAL, you need to debug them in a variety of ways, such as setting breakpoints, stepping through code, outputting debugging information, and so on.The 1.PRINTK function runs in kernel space, and the printf function runs in user space.Initialize Linux driver: Static int _init printk_demo_init (void);Uninstall Linux driver: Static void _exit printk_demo_exit (void);2.
