What skills are required for software testing

The professional skills in the field of computer science is a prerequisite for testing engineers. While anyone without an IT background can work on a test, a test engineer who wants to develop more space or have a lasting competitive edge is essential to computer expertise.
Computer expertise consists of three main areas:
⒈ Test Professional skills
Testing expertise, the content of this book mainly to test personnel should master the basic professional skills. Testing expertise covers a wide range of basic testing techniques including black-box testing, white-box testing, test case design, unit testing, functional testing, integration testing, system testing, performance testing, and basic test process management, defect management, and automated test technology.
⒉ Software Programming Skills
Software programming skills should actually be one of the testers ' skills, and many testers have many years of development experience at Microsoft. As a result, testers must be able to write programs to achieve better career development. Only the ability to write programs, such as unit testing, integration testing, performance testing and other difficult test work.
In addition, the programming skills requirements for software testers are different from those of developers: testers writing programs should focus on running correctly, while taking into account the high efficiency, especially in writing test code related to performance testing. Therefore, the tester must have certain algorithm design ability. Based on the experience of experienced test engineers, test engineers should at least master a language such as Java, C #, C + + and corresponding development tools.
⒊ Network, operating system, database, middleware and other knowledge
Compared with the developers, the knowledge of the testers has the characteristics of "unfocused", and "art is not pressed" is a very figurative metaphor. As the test often needs to configure, debug a variety of test environments, but also in the performance test to the various system platform analysis and tuning, so testers need to master more network, operating system, database and other knowledge.
In the network, the tester should master the Basic network protocol and network working principle, especially to master some network environment configuration, these are often encountered in the test work knowledge.
Operating system and middleware, should master the basic use and installation, configuration and so on. For example, many application systems are based on UNIX, Linux, which requires the tester to master the basic operational commands and the associated tool software. and WebLogic, WebSphere and other middleware installation, configuration many times also need to master some.
Database knowledge is more to master the skills, the current application system is almost inseparable from the database. So not only to master the basic installation, configuration, but also to master SQL. At a minimum, testers should be familiar with the use of common databases such as MySQL, MSSqlserver, and Oracle.
