First, be sure to submit!!1. Remember that there is such a flaw, you may encounter later when you will understand the cause of the occurrence.2. Try to find out the cause of the error, such as any special operation, or some operating environment.3. Programmers are more familiar with the program than testers, perhaps you have submitted, even if not re-, the programmer will understand the problem.4. Once again the problem cannot be reproduced, you can call the programmer to see the problem directl

1. Release testing refers to giving your program* Your tester, because the program is always to be tested. * before the official release, the customer must first check and accept the applications on their iOS devices (iPhone, ipod, iPad) installation, run. 2. Prerequisites: you have completed the real machine test, which means: 1. You have joined Apple's "iOS Developer Program" and paid $99 for the event. 2. A development certificate is generated on t

Specific defect management methods are available for different test tools or projects. Today, I reviewed the defect management materials and summarized them. Classification of bugs: 1.

Why scripted testing is not for novices Why is script testing not suitable for beginners? Note: This is a recent blog by James Bach. I have simply translated it. Link to the original article: Why scripted testing is not for novices ... Unless you want bad testing. Why is script-based testing not suitable for beginners...

to the Internet. In fact, many network faults are not caused by problems with network switches, routers, network cards and other devices, but by poor quality of Network cables, crystal heads, or socket modules. Network disconnection or slow speed is mostly caused by poor network quality and high impedance signal attenuation. In overcast and rainy weather, disconnection often occurs, most of which is caused by bad quality of metal connectors of crystal heads or network modules and mildew. Some m

Currently, manufacturers of Structured Cabling solutions have released Cat5E and Cat5E solutions. Although the six types of cable standards have not yet been promulgated, many customers have chosen to implement this solution in view of its superior performance. What prompted them to install these systems even if the six standards are not finalized and there is no hope of release of the standards? Obviously,

I. Common LAN Topologies 　 Computers and other devices in the network need to be connected in a certain structure. This connection method is called "topological structure ", in general, how are these network devices connected together. Currently, the following network topologies are common: 1) Star Structure 2) Ring Structure 3) bus structure 4) Star-and total-line Compound Structure Next we will give a one-to-one introduction to these network topologies. 1. Star Structure 　 This structure is

material, only a layer of insulating rubber package, the price is relatively cheap a lot, but also can make their own, the advantages are no shielding housings, light weight, easy to bend, good flame-retardant effect. In addition to the electromagnetic radiation severity, high transmission quality requirements such as the use of STP in the wiring, in general, we are using UTP. UTP Twisted pair is also graded, the existing UTP can be divided into three categories, four categories, five categori

Risk-based testing allows almost every tester to use it more or less in testing practice. For risk-based testing design, the tester must first consider where the risk is? That is, identifying and analyzing risks in a test object is a prerequisite for conducting a risk-based test design. Risk-based testing design can adopt the following techniques: heuristic analysis methods, attacks, failure modes, and impa
