fault under the expected environmental conditions (this definition is only relevant to the correctness of the software function. Because there is no definition of the Operation section, the entire input field is considered to be evenly distributed. The environment refers to the hardware and software elements required to run the software, including hardware devic

Introduction A few years ago, after graduating from school, my first job was software testing. At that time, most software companies in China had no idea about software testing. In addition to the Computer Software

One: The purpose and principle of software testing Software testing is to find the wrong, with as few tests as possible to find as many errors as possible. Principles: 1, early, 2, from small to large, 3, test plans, 4, to envisage errors in the program, 5, the test does not prove that the

Abstract: With the rapid development of science and technology, the software has become more and more powerful, and the complexity of the software has become higher and higher, thus greatly increasing the difficulty of software testing and reliability evaluation. In order to ensure the quality of a

This blog goes on to introduce the white box test, in the absence of specific contact with the white box test before, always feel that he is very mysterious, very complex. I'm sure everyone will feel that way. Let's open the box today and dissect the white box test. White box test The white box test is also called the structural test or the logic drive test, it is to know the product internal work process, can pass the test to check whether the product internal action according to the specifi

It's a bit irrelevant, but it's a technical software test, not just a technical software Test engineer, and that's what our team needs to do. Here are some considerations for testing the software in the test group: 1. About Demand Analysis Complex needs are like a tangled ball of wool that cannot be found at the beginn

"stress test" comes from. NET application Performance test: The stress test is used to assess how the system will run when the maximum load is exceeded. The goal of stress testing is to find bugs in applications under high load conditions. Includes: Synchronizationissues,raceconditions,andmemoryleaks (memory leak). Stress testing allows you to identify the weaknesses of the program and how the program will

Too much, this is an ancient "Analects of Confucius" in an idiom, do it as if not enough to do the same. In the software testing industry there is also the situation of excessive testing, today I would like to swim a fish to talk about my understanding of the excessive testing. Very detailed requirements documents can

This article introduces a variety of Linux systems, server testing software. There are many wrong places, please correct the reader. a SPEC2000 Spec CPU2000 is a benchmark program test group developed by the standard performance evaluation agency "The Standard Performance evaluation Corporation (SPEC)" for evaluating CPU performance. processors, memory, and compilers all affect the final test results, while

performance. The server performance is measured by TPS, which has little to do with the number of user concurrency. Considering a single script, the Conversion Relationship between user concurrency Vu and TPS is Rt, which is the time for the script to complete all operations at one time. If there are m transactions in each script and N scripts in total, the total TPS is :. (Note: you have doubts about the conversion relationship) For new systems, TPS and Vu acquisition can only be evaluated

, and software enterprises are facing huge challenges. The requirement on software product quality is constantly improved, prompting software enterprises to improve software quality as a strategy to enhance competitiveness. Where are the factors for improving software qualit

Two aspects of software testing. White-Box testing: Testing through the source code of the program without using the user interface. This type of test needs to be revised from the code syntax to find flaws or errors in algorithms, overflows, paths, conditions, and so on. Black-Box

arranges Review,review leader for guidance, and the role behavior is duplicated with decision maker. The rest can be literally understood. Formal reviewFormal scrutiny is formal and belongs to a static approach that needs to be followed by an established procedure. Roles include inspection leader, Reporter, Reader, Author, Inspector. It is important to note that all people are inpector,anthor and not as leader and reader. DayThe daytime is more casual and can be used to train listeners, i

CMM process of the overall idea, one is based on the distrust of people, so set up a variety of processes, documents, checklist, to check whether to achieve indicators, only to reach the target to go down. Second, downstream work is based on the upstream of the document, the general downstream of the work is not the right upstream, so the upstream work requirements higher, once the upstream work out of the problem, follow-up work and no one can point out, then the whole work may have problems. S

has been doing performance testing for two years, has been a random collision, East Learning Western learning, are some superficial things, rarely think of their coherence. Today, according to their own understanding to write a performance test to a certain stage need to stand up to a height to look at the performance of the problem. Many enterprise recruitment are only write performance test, will use the Lr,jmeter tool. In fact, using JMeter and LR

Acceptance testing is a stage of the system development lifecycle methodology. At this time, the relevant users and/or independent testers test and receive the system based on the test plan and results. It allows the System user to decide whether to receive the system. It is a test to determine whether the product meets the contractual or user-defined requirements. This is administrative and defensive control. Ad hoc

turns of the analysis, and can not only choose a time range of twists and turns, Select at least one curve with more than two twists and turns. If you select only one twist, after automatic association, you will find that many items have a correlation of 100. This analysis does not make sense, because only one of the twists and turns of the time range is too small. Figure 12 (set time range) 4 Analysis of correlation degree. Automatic Association will see the following list of all the relevan
