Today a lot of people dream of finding a job in IT, because of the industry's relatively high salaries, as well as the consistent demand for IT specialists in the labor market. Most often, these dreams shatter when they run up against the need for specialized education that the dreamer has neither the time nor money to obtain. But there are several specialties that provide a "back door" into the IT industry, allowing you to essentially bypass preliminary training and the need to gain prior experience. As it happens, QA is one such specialty on the "edge" of IT.
What is a QA engineer and what does he or she do?The work of a quality assurance engineer is less about assuring quality (although this is implied by the job title) than about monitoring the correctness of the implementation of all stages of development and the correctness of the operation of the final product. It sounds a bit like what a tester does. But a tester is only checks the operation of the application and either accepts or rejects it based on the test results (the presence of bugs and errors). A QA engineer also monitors compliance with standards in software development and interacts with developers, designers, and customers, preventing the very appearance of bugs and errors in the software. It's true that the positions of tester and QA engineer are very often perceived to be one and the same.
If we break it down point by point, then a QA engineer's job description includes the following tasks:
- specify detailed requirements for the program (done together with the customer)
- analyze and calculate of the time required to create the application or fix a bug (this task, of course, is not for junior QA engineers, but someone with an impartial perspective, a QA professional gives the most realistic time estimates)
- develop test scripts
- perform the testing process itself
- log discovered bugs in the bug tracking system
- discuss fixes with everybody involved in development
- track the bug-fixing process
- repeated testing of problematic areas
- analyze test results
- debug test scripts
- analyze the processes used by the development team
- optimize development processes to prevent the re-occurrence of detected errors (if errors are happening due to inconsistent actions taken by different departments or because someone isn't following established development standards, then it is the QA engineer's job to point out where the problem is happening and work to eliminate it);
- maintain test documentation
