Software Engineering-software testing, Software Engineering Software Testing
After the system is complete, it is time to test the system. This must have been the first system of acceptance. We are confident that the system will be
When interviewing testers, This is a good question: How do you define performance/load/stress testing? In many cases, people use them as the same terminologies that can be replaced by each other. However, the differences between them are quite large. This post is based on some of my own experiences. I wrote a simple comment on these three concepts. Of course, I also referred to some definitions in the test documents, for example:"
Software testing is a process used to promote the correctness, completeness, security, and quality of the certified software. The goal is to quickly identify the problems that exist in the SOFTWARE product as soon as possible-with user requirements, pre-defined inconsistencies, that is, to find as many defects and de

Support for the entire test lifecycle (but not for the AST, you need to apply throughout the test lifecycle).
Support for distributed testing across multiple computers and in various systems engineering environments.
If applicable, it supports the reuse of the AST framework and components between multiple programs.
The implementation of the AST requires a small development lifecycle, including test requir

Several misunderstandings about software testing
As the market continues to improve the quality of software, software testing has been paid more and more attention. However, because the process of software projects in China
. testing by third parties will be more objective and effective.Programmers should avoid testing their own programs for best results and should be tested by a third party. Testing is a "critical" behavior, and mental state is a barrier to testing your own
test phase.
4. the process quality assurance of the entire software product is completely dependent on the developer's ability and responsibility for the work, and the results of the previous step must be adequate and correct. If a problem occurs at any stage, it will seriously affect the quality and expected progress of the entire project.W Model
The W model was proposed by evolutif. Compared with the V model, the W Model adds verification and valid
Some of the status quo
Now most of the software enterprises are the ecological chain, software testing is the most downstream. This also determines that many situations must be passively accepted. Even if a test engineer has a rich theoretical knowledge and a strong ability to identify risks, a change in the demand for a product can make him dumbfounded and then
Software testing objects include: source program, target program, data and related documents

The reason for writing this blog is that little Dizzy is a little naïve to ask: can you tell me or help me to find some news about the software testing industry ah, such as new technology Ah, new ideas ah, new statistics and so on, want to know more about, although the test is generally lagging behind other technologies, but Baidu search is not very new.

consciousness of the whole people. I think it is awesome because every employee is a member, each product is not only the company's image, but also the embodiment of each of us, but our division of labor is different, but it represents us, in addition, I think such a management concept can also have the power to unite people, so that everyone can do things better together! Instead of relying solely on testing, we finally become more and more lazy. I
solve the above problems through standards and test content, such as: Number of bugs Left severity, test case execution Rate pass rate, etc. Software testing does not show potential defects in software
Testing can be done to find and report the software defects and errors
1. The "Black Swan" in software testing
A few years ago, I led a Test team to omit a serious bug to the Internet, when the user feedback the bug, we analyze it deeply and reproduce it, and ultimately everyone agrees that it is a coincidence that this bug can happen because it requires multiple conditions to occur at the same time to trigger it, such as " XX algorithm switch must be opened, XX algorithm swi
Given the appropriate definition of software testing, the next step is to determine whether the software test can detect "all" errors. We will prove that the answer is in the negative, even for a very small program. In general, it is impractical and often impossible to discover all the errors in a program. This basic question, in turn, hints at the economics of
Usually two choose one, the most brutal. Choose one that is bound to give up another. But for testing and development, you have me, I have you is the highest state. Which one is right for you?

Because data is read from memory faster than it reads from disk, memory is often leaked or overflowed, and attention needs to be focused.Less memory is available for a short period of time and does not necessarily indicate a memory leak or overflow.

Software testing is the process of executing a program in order to find errors, which means that the purpose is to find errors, and the action is to execute the program.In the process of software testing, to follow a number of principles, the following are several important test principles:1) A required part of the tes
