Chapter 1, 2 and 3 of the Law of construction

Chapter I.

Read about the process of understanding software from an idea to the final product. The software is led by an idea, there is the idea, you need a tool to do what, and then according to the function you want to do a basic function of the software, and then to improve the requirements of customers, to achieve the function of the software maintenance.

There is to do the software to meet customer requirements, rather than just according to their own ideas to do, to meet the majority of the needs, to meet the needs of customers, in the use of the process found a bug to repair it .

Chapter II

After reading the second chapter know that the software is required unit testing, before this is not a concept, and unit testing to be synchronized with the software update, unit testing to cover all code paths, unit testing can be done by your software can not do things in the "unit" in the expression. If there is no unit test, sometimes some of the hidden dangers themselves do not know, until the later discovery and modification is very complex. In the case of a unit test , later bugs are easier to fix, and it's easy to know what the error is and where.

Requirements analysis and testing time than writing code, the formation of software should pay more attention to demand analysis and testing, so as to reduce the software later appearing bugs, more meet the requirements of users, software can always be used and continue.

Question: How do we begin to write unit tests when we don't write unit tests like this? What if I don't know if I wrote a unit test incorrectly?

Chapter III

This chapter describes the personal ability of the measurement, said the software engineers, some of the growth and career development, first of all to learn the introduction of knowledge, the accumulation of software development knowledge, and then practice, improve their skills, solve problems by themselves, become their own brain automatic operation of things, so as to improve their skills, First encounter problems Baidu, not the second third after encountering the same problem or Baidu, so the practice of how long no progress, there is to expand their knowledge, follow the pace of the times. It's not easy to be eliminated.

Question: Do you want to take more test grade? The more certificates, is it better to go out and find a job?
