From zero basic to IT, how to choose software testing and cloud computing operation and maintenance? Many people who don t understand don t know how to choose. So for this question, let s first understand what software testing engineer and what cloud computing operation and maintenance engineer?
Software testing: (the process of comparing actual output and expected output) describes a process used to promote the correctness, integrity, safety, and quality of software. In other words, software testing is a review or comparison process between actual output and expected output. The classic definition of software testing is: the process of operating a program under specified conditions to find program errors, measure the quality of the software, and evaluate whether it can meet the design requirements.
What does software testing do? Software testing is to use testing tools to perform functional and performance tests on products in accordance with test plans and procedures, and even write different test tools as needed, design and maintain test systems, and analyze possible problems in the test plan And evaluation. After executing the test cases, the failures need to be tracked to ensure that the developed product meets the requirements.
Software testing is a job that is easy to get started, but difficult to go deep. Let's take a look at the editor of Xi'an Software Testing Training. What do we need to learn in software testing?
5 types of advanced development languages: C++, JAVA, Python, Android, HTML5
3 kinds of enterprise-level databases: Oracle, MS SQLServer, MySQL
6 major testing tools: HP UFT, HP LoadRunner, HP ALM, Selenium, JMeter, Robotium
Full stack testing technology: functional testing, performance testing, black box testing, white box testing, interface testing, full stack testing technology: functional testing, performance testing, black box testing, white box testing, interface testing, A/B testing, testing , Interface test, interface test, PC terminal test, mobile terminal test...
It has been ten years since the development of cloud computing. Today's cloud computing has undergone tremendous changes from technology types, functional products, to industries and markets. Many enthusiasts' cognition and demand for cloud computing have also developed from the superficial concept of the year to the stage of eagerness for in-depth exploration. Due to the differences in the individual abilities of the majority of enthusiasts, the individual technical level is also different. Here are some suggestions for beginners and cloud computing engineers:
If you are a person who has never done cloud computing-related work and you need to learn cloud computing, you must have knowledge of operating systems, networks, application services, etc. There are already many vendors on the market that implement cloud computing. In the commercial camp, Microsoft, IBM, Google, VMWARE, and Huawei all have very mature products. If you have sufficient funds and buy any cloud product, you will get very professional technical support and services. (Just kidding, you can't usually afford it) If you are just an ordinary hobbyist, I suggest choosing KVM, XEN, OPENSTACK, DOCKER and other technologies in the open source camp. Because of their open source (free) features, so in recent years It is widely praised by major IT Internet companies and enthusiasts.
To learn the cloud computing technology of the open source camp, it is necessary to learn from the perspective of the management and use of the Linux system (about 20 days), as well as a small part of computer network communication technology (about 5 days), to lay the foundation for virtual network technology in the cloud. Later, I need to have a certain understanding of SHELL development and database system (about 10 days). At this time, there are conditions to carry out a comprehensive study of the core cloud computing technology. Such as: KVM, OPENSTACK, DOCKER container, and other cloud technologies (20 days). Master the architecture, functional roles and hierarchical classification of Iaas, Paas, and Saas, and master the deployment and operation and maintenance capabilities of private clouds.
If you are a person who has already participated in related work, you have some understanding of the above content. The suggestion for you is that while proficient in the above content, you also need to learn the language of Python in-depth, and be able to perform a full range of common servers such as cloud computing services, container services, cluster services, and caches on the cloud platform. The monitoring and management work, and the secondary development work. This can be counted as a more comprehensive cloud computing expert. Because what you will face is not the independent server, computer room, and equipment of the past. But tens of thousands of computers, and cloud computing systems distributed in different cities or countries, carry out all-round efficient and stable management. In summary, switching to IT, software testing and cloud computing operation and maintenance are all suitable for Xiaobai's zero-based learning, and can choose according to his own preferences.
