1. Check Hardware requirements The system must meet the following minimum hardware requirements: At least 1024MB of physical memory The following table describes the configuration relationship between physical memory (RAM) and swap area (swap space) at installation time. RAM Swap Space 1024 MB to 2048 MB 1.5 times times RAM 2049 MB to 8192 MB equals RAM is greater than 8192 MB 0.75 times times RAM A

itself is faulty. You can first connect the hard disk to another computer and try again. If the problem persists, You have to repair it.(9) floppy disk (s) fail or floppy disk (s) fail (80) or floppy disk (s) fail (40)Translation: unable to drive the software drive.Resolution: first check whether the soft drive line is connected incorrectly or loose, and whether the power cord is connected properly. If there is no problem, it may be the fault of the

, you should fix it immediately and then look for other problems. Only fixed a known error to focus on finding other problems, sometimes fixing one problem, and the other disappearing, which is a bug in two questions.5, first eliminate noise interferenceIn hardware, noise may also be difficult to find a variety of intermittent problems, so before looking for problems, you should first pay attention to the short-term pulse interference, clock echo, ana

o'clock in the afternoon is the time for everyone to take a coffee break, because the large number of operations on the vending machine beyond the scope of the server to cause its collapse, it is easier to find the bug.4, for the design of audit trail is also very usefulSoftware version Control tool, can tell you that version of the revision introduced a bug, and sue you two versions of the difference. Currently, it is recommended to use GIT version management tool locally, each modification of

will start Netty's thread service startup class, it will run Netty's main configuration class, Bossgroup is the link instance that handles the connection, Workergroup is the link to work, and our handling of the business is placed in Tcpserverhand Ler inside, I have a unique ID for each instance of the storage, so that the service layer can get to the link instance through the ID, then order or broadcast instructions, while Tcpserverhandler also have the operation of the database write, which f

. There are also a number of changes that need to be validated, and many bugs in software testing need regression testing. There is a lot of repetitive work in these jobs, and it is necessary to introduce and apply the method of automatic test of function. Automated test methods When we use automated test tools to perf

sandwich integration can be used.(3) Systems test system TestingThe final phase of the test before the product is submitted to the user during system testing. The so-called system testing, is the confirmed software, hardware, peripherals, networks and other elements together to carry out a variety of information syste

In the last lesson, the teacher talked about the analysis of software defects. First of allSoftware defects can be divided into:1. Input/output defects2. Logic defects3. Calculation of defects4. Interface defects5. Data defectsthe production of software defects：1. Errors caused by negligence (carelessness defect)2. Do not understand the errors caused (misapprehend defect)3. Two errors caused by semantic (am

　Ixchariot IntroductionIxia's application layer performance testing software Ixchariot is a unique testing tool and is an industry-proven test system for application-level performance testing. Ixchariot can evaluate the performance and capacity of network applications, stress test the network and equipment, and get the performance parameters such as throughput, d

-frequency testing program", we should note that some people are not sensitive to the signals in this frequency band, so they do not have to be too demanding; when testing too low frequency signals, if you use a small speaker, you may see the phenomenon of "only playing the bass, not smelling the bass. Sound speakers can be heard at 80 or Hz. Of course ~ 60Hz makes it better for you to hear it.Overall test performance[FAQs]Under normal circumstances,

　Automated testing refers to the automation of software testing, which is to run the system or application under preset conditions, evaluate the results of the operation, and pre-conditions should include normal conditions and abnormal conditions.Automated testing is the process of translating a man-driven test behavior into a machine execution. Typically, after a test
