Tester-like profession

Error Catcher, Program Taster

The profession of a tester (QA-specialist) is becoming increasingly popular in the computer industry. Companies in a highly competitive environment seek to provide the consumer with the highest quality product. QA specialists are often novice programmers with a passion for computer technology who are ready to check codes and calculate errors, keep abreast of IT developments.

general description
A tester is a specialist who evaluates software quality. It performs two functions: user and software expert. The abbreviation QA stands for quality assurance, which literally means “quality guarantee” in English. “Despite the fact that it is rather difficult to touch the fruit of a QA-specialist’s work, it directly affects not only quality, but also the very essence, the product concept,” says Alexander Zaliznyak, GlobalLogic tester. Testers look for bugs and software malfunctions, and then give programmers feedback. Thus, the tester or testing group becomes indispensable in the process of software release - a kind of filters for product flaws before entering the market. Often, QA-specialists become not due to skills and vocation, but for the sake of sports interest: such people are attracted by the opportunity to be the “pioneer” of a new program or computer game. There are also alpha and beta testers. The former, together with the programmers, work on the product and are engaged in full or partial testing. A beta tester is a user who performs the functions of beta testing, as well as officially published versions, and so on. release candidates of the program.

Education
Ukrainian universities do not offer specialized education for testers. There is an opinion that a QA specialist is a failed programmer. In fact, it is not. However, it is not really necessary to be a programming genius to test software. As a rule, employers welcome higher technical education in the field of information technology (for example, in the following specialties: “automated information processing systems and management”, “computers, complexes, systems and networks”, “computer science and computing equipment”, “information systems and technology"). A good addition to the tester's resume is a certificate of completion of specialized courses, especially on automated testing, as well as the availability of international ISTQB Certified Tester Foundation Level.

Functional responsibilities
The main functionality of a QA-specialist can be formulated as follows:
Development of plans, schedules, methods and descriptions of testing.
Artificial creation of situations that in actual use of the program may give an error.
Development of test software modules.
Filling database tables with test indicators.
Feedback on the analysis of the results obtained during the passage of the tests.
Control of the process of eliminating the detected errors by the software developer.
Communication with developers and clients.


Knowledge, skills
Obviously, the tester should be well versed in the Internet, have the skills and experience with web applications. Employers welcome knowledge of HTML, JavaScript. Prefer candidates with experience of two years in the development and testing of software, test documentation. An advantage in employment will be the availability of experience with Oracle and / or MS SQL DBMS, as well as the use of test automation tools. Frequent desire of companies is the availability of knowledge and experience in the field for which software is developed (for example, when working with the 1C program - basic knowledge in accounting). If the work involves communication with foreign clients, fluency in English is required.

Personal qualities
The work of the tester is painstaking, and therefore requires attentiveness, patience and perseverance, a willingness to work on improving the program from version to version. The tester must have excellent memory and analytical thinking, be balanced and reasonable. QA-specialist helps communication skills and ability to work in a team. Readiness to strictly follow the rules is appreciated, but at the same time initiative and curiosity, interest in experiments is welcomed. A tester is, in fact, an engineer and a user in one person, so he should be able to analyze the product from the standpoint of both.

Pros and cons of the profession
An undeniable positive feature is the ability to work remotely. It is also worth noting that today the demand for testers exceeds supply in the labor market, and therefore they will not remain without work. In addition, this position is a good basis for professional and career growth. This is confirmed by Alexander Zaliznyak: “Ukrainian testers often have to work with foreign customers, thanks to which their knowledge of the language, understanding of cultural differences and business ethics are improved. And this is useful not only for testers, but also for every professional. ” The disadvantages include the monotony of the working day. But this argument does not seem so compelling, given the prospects for upgrading to more responsible and creative IT positions and the possibility of changing the project, a chance to be the first to see and "taste" the new program. Sometimes the work of a QA-specialist is complicated by the fact that the company does not have the necessary basic resources - for example, documentation of software errors, which requires re-testing and negatively affects the results of work. But this is rather the problem of individual employers, rather than the profession as a whole.

Salary
The salary depends on the complexity of the project the tester is working on and his level of responsibility. On average, Ukrainian companies offer a reward of 2.5 to 12 thousand UAH.

Perspectives
QA-specialists have the opportunity for vertical career growth. For example, they can reach the following career heights: lead tester or test team leader. That is, from a simple executor to grow up to a manager, and this requires a qualitatively new set of knowledge and skills - from the basics of psychology to the art of managing a company. In addition, a tester is an excellent preparation for a programmer's position: analyzing and evaluating software, a QA-specialist can create it in the future. The perspectives of the tester depend on the specifics of the work - he can become a test designer or test analyst, and then an automated testing engineer. It is quite possible and horizontal professional development - through the development of new testing technologies, participation in projects with different content.

System engineering is designed to provide training for specialists in the development and implementation of computerized management information systems. Systems engineering covers the processes of describing, designing, implementing, testing, implementing and maintaining complex systems as a whole.
Software engineering teaches the construction of complex software systems that require the coordinated work of teams of programmers of different specializations and qualifications. This direction, in addition to programming itself, is intended to teach a systematic process of designing, developing and maintaining software.
Computer engineering is engaged in the development of computer systems and networks nodes and their integration, research in the field of robotics. Computer engineers design individual microprocessors and computers, integrate them into systems and networks. Their tasks include writing software for embedded microcontrollers, designing VLSI (extra large integration scheme), developing operating systems, designing analog sensors, etc.
Applied mathematics provides training in the fields of application of mathematical methods to scientific, technical and production problems. As a tool, specialists use IT tools to solve a wide range of engineering problems in industrial, economic, environmental, economic, and cybernetic activities.
Security of information and communication systems is prepared by specialists capable of developing and using mathematical methods, models, software and hardware and software for protecting information in the SEC (developing models of threats and violators, risk analysis, shaping security policies, software for protecting information, cyber security).
Systems analysis teaches you to make decisions based on mathematical research methods. System analysis is a set of methods based on the use of computer technologies and focused on the study of complex systems - technical, economic, environmental, etc. The result of system research is the choice of a well-defined alternative: a regional development plan, design parameters.

QA / QC / Test Engineer
