A software quality assurance QA engineer monitors every phase of the development process to ensure that the design and software adhere to company standards. Software delays are costly for a company, so it's vital for releases to meet target dates and stay within budget. A software quality assurance engineer helps meet deadlines by breaking up the development process into attainable testing goals and relaying any issues back to the development and product teams or leaders.
A QA engineer's duties can be diverse and comprehensive. They generally perform the following tasks with some regularity:. Software and computer technology tend to be higher paying fields. Source: U. Bureau of Labor Statistics A QA engineer should have a thorough understanding of QA testing environments and software development life cycles.
Education and licensing are also required. A software quality assurance engineer must have strong skills in a variety of categories: engineering and technology, math and science, verbal and written communication, problem-solving, reasoning and logic, and practical skills. These can include:. It's expected that more than 22, jobs should be added from through Software quality engineers work in a variety of fields.
You might find them assessing whether an airplane's control system meets required performance standards, designing a plan to test potential human errors in an automated system for drug delivery, or making sure a video game won't crash just when you're about to take out the bad guy.
You'll spend some of your time alone, on the computer, analyzing information and solving problems, but this isn't to say that you'll work in a human void. This is generally a full-time position, but it can depend on the company.

Comparing Similar Jobs.The main difference is the recipient of the said processes and the goal of each process. Testing is also commonly referred to as quality control. It is a preventive measure or method to ensure the quality of a certain product or service.
Quality assurance, in comparison, is the process of the quality in the process or the methods used in order to produce a quality product. Testing involves the actual operation or use of the product in very controlled and various conditions.
Results are written, cataloged, stored, and interpreted in order to assess whether the product is up to the prescribed standards of the company and the market. If the product passes testing, it is ready to be marketed and distributed to the public. Meanwhile, quality assurance involves ensuring the quality of the process before the actual testing.
It also involves the entire process of product development from monitoring to evaluation. Within the process of quality assurance, standards, specifications, and other evaluative methods are considered and followed. Another part of this process is to discover potential problems or anomalies in the product or service. The goal of both processes also differs. The goal of testing is detecting and finding errors and recommending procedures on how to prevent them while the goal of quality assurance is to prevent errors.
Testing must comply with the pre-determined standards, regulations, procedures, and methods before conducting the actual test. In doing things this way, the product is being ensured of its quality. Testing also acts like a validation process for the product. On the other hand, since quality assurance deals with the process that the product undertakes, it assures that quality, not just of the product but of the method, will be reached at the end of the process.
This makes quality assurance as a form of verification. Also, in terms of quality, testing is more product-oriented while quality assurance is more process-oriented.
Quality assurance comes first before testing and usually starts at the initial onset of the project. It determines the standards and procedures before the actual testing.
Software Testing Metrics & KPIs
What is being decided is what will be executed on the actual testing itself. Standards for quality assurance can be determined by an independent team aside from the team who will conduct the testing. Also, the process in the quality assurance is independent from the process of testing. The concept of quality assurance is also wider and larger in scope compared to testing.The questions will emphasize more on the quality processes and the strategy and these questions will not be asked for Testing.
Answer: Quality Assurance is the process of planning and defining the way of monitoring and implementing the quality test processes within a team and organization. This method defines and sets the quality standards of the projects. Quality Control is the process of finding defects and providing suggestions to improve the quality of the software.
The methods used by Quality Control are usually established by quality assurance. It is the primary responsibility of the testing team to implement quality control.
It validates whether the software built by the development team meets the requirements set by the user and the standards set by the organization. Q 2 When do you think QA activities should start? Answer: QA activity should start at the beginning of the project. The more early it starts the more beneficial it is to set the standard for achieving the quality.
Answer: Test Strategy is at a higher level, mostly created by the Project Manager which demonstrates the overall approach of the testing for the entire project, whereas the Test plan depicts how the testing should be performed for a particular application, falling under a project. Answer: Software Testing Life Cycle refers to a testing process that has specific steps to be executed in a definite sequence to ensure that the quality goals have been met.
Q 5 How do you define a format of writing a good test case? Answer: In simple words, a good test case is one that finds a defect. But all test case will not find defects, so a good test case can also be one which has all the prescribed details and coverage. Q 7 What would you do if you have a large suite to execute in very less time? Answer: In case we have less time and have to execute the larger volume of test cases, we should prioritize the test case and execute the high priority test cases first and then move on to the lower priority ones.
Alternatively, we may also seek customer preference that which is the most important function of the software according to them, and we should start testing from those areas and then gradually move to those areas which are of less importance. Q 8 Do you think QA's can also participate to resolve production issues? Answer: Definitely!!
It would be a good learning curve for QA's to participate in resolving production issues.
Many time production issues could be resolved by clearing the logs or making some registry settings or by restarting the services. Also, if QA has an insight into resolving the production issues, they may include them while writing the test cases, and this way they can contribute to improve quality and try to minimize the production defects. Q 9 Suppose you find a bug in production, how would you make sure that the same bug is not introduced again?
Answer: The best way is to immediately write a test case for the production defect and include it in the regression suite. This way we ensure that the bug does not get introduced again.
Also, we can think of alternate test cases or similar kinds of test cases and include them in our planned execution. Q 10 What is the difference between Functional and Non-functional testing? Functional testing deals with the functional aspect of the application. This technique tests that the system is behaving as per the requirement and specification.
These are directly linked with customer requirements. We validate the test cases against the specified requirement and make the test results as pass or fail accordingly. Nonfunctional testingon the other hand, tests the non-functional aspect of the application.QA Manual Testing Full Course for Beginners Part-1
It does not focus on the requirement, but environmental factors like performance, load, and stress. These are not explicitly specified in the requirement but are prescribed in the quality standards. So, as QA we have to make sure that these testing are also given sufficient time and priority.A lot of what they do involves making sure that software does what it's supposed to do.
On a day-to-day basis, they create test plans and test cases to determine whether certain parts of the program function as written. When problems arise, they are responsible for finding and debugging rough spots in the code. QA Software Engineers also review user interfaces to ensure functionality and uniform design. For You.

Not only does it work, but is consistently followed by the team. Moreover, QA is about engineering processes that assure quality is achieved in an effective and efficient way. The QA process verifies that the product will continue to function as the customer expects. Though QC is absolutely necessary, QA is perhaps more important. By the time you reach the QC stage, for instance, fixing bugs becomes an expensive issue. Because of that, focusing efforts on improved QA processes is one of the best investments an organization can make.
Examples of QA include process definition and implementation, training, audits and selection of tools. Quality controlalternatively, is product oriented. It is the function of software quality that determines the ending result is what was expected.
Whereas QA is proactive, QC is reactive. QC detects bugs by inspecting and testing the product. This involves checking the product against a predetermined set of requirements and validating that the product meets those requirements.
Examples of QC include technical reviews, software testing and code inspections. It is the process of executing a system in order to detect bugs in the product so that they get fixed.
Testing is an integral part of QC as it helps demonstrate that the product runs the way it is expected and designed for. To summarize, think of everything as an assembly line. QA can be thought of as the process to ensure the assembly line actually works, while QC is when the products coming off the assembly line are checked to verify they meet the required specifications. Ultimately, both QA and QC are required for ensuring a successful product.
When used together, they can help detect inefficient processes and identify bugs in the product. Moreover, QA and QC can help to develop and deliver a consistently high-quality product to your customers. Similar posts.

Difference Between Testing and Quality Assurance
When that happens, we lose perspective about what it means to be one thing or the other. Is there a difference between them? Would you consider yourself or the people you work with to be one versus the other? Or are those two titles interchangeable? People often confuse these terms, but the roles are actually quite different.

Obviously these are only two job listings among thousands, but what you see here does in fact begin to reveal the key difference between being in QA and being in testing. A software tester is charged with finding bugs before users do. They investigate and report on how well the software performs relative to its expectations.
However, in QA, you are asked to assure the quality of the software. Lots of people share this perception of how these roles are different, and why a QA Engineer has so much more opportunity to make an impact. In each project, the software testing group is now responsible to reach that goal. Remember, your title and your job may not be aligned.
Furthermore, neither your job nor your title defines you. Challenge the status quo, ask the next question, and continue to push the boundaries. Performance problems can point to issues deep in the code, and so the sooner you identify them, the safer you will be.

The Australian IT industry still views testing as a job that anyone can perform with minimal technical skills. A quick search on a leading recruitment site has a number of advertisements for Testers with requirements similar to the following:.
This ad is typical of those here in Australia for testing positions. Their testing careers page has the following description:. Software Design Engineer in Test Tests and critiques software components and interfaces in more technical depth, writes test programs to assure quality, and develops test tools to increase effectiveness. The key difference, however is they have a different focus, and have different goals.
Any tester that is not finding issues, regardless of role is not a tester. They are a tool developer. So yes, they need to find bugs. The shouldn't require it as a pre-requsite, but they should be required to develop it as they automate. If they don't then a they are not testers and b they won't be effective. They need to do everything a tester does, plus build or use testing tools. Their main focus will be on writing automated checks, but they could also be generating test data, building test process tools, test harnesses, performance testing, security testing etc.
Some of this answer is based on a blog post I wrote ages ago here. Some companies to not differentiate roles based on title. When I started in '94 only people whose primary job was to build and maintain test infrastructure were called SDETs because even STEs were expected to be at least somewhat proficient in coding Today all testers at Microsoft have a title of SDET and are expected to be proficient in at least 1 programming language.
When you are looking at roles at different companies look at the job descriptions. If there are different titled roles, then I recommend that the company does differentiate the roles and have clear career paths for each role. Every tester regardless of what their "official title" is performs manual tests. I run a team that focuses on testing the underlying APIs in Windows Phone, so my team spends a lot of time writing automated tests.
However, we also spend a lot of time doing exploratory testing because ultimately we need to understand how the functionality manifests itself to the customer and because we want to produce a great product we think our customers would like. In fact, anyone on the product development team is responsible for finding bugs.
QA Engineer job description
Even developers write unit tests that find bugs. In companies such as Microsoft that don't differentiate between the roles all testers are required to be capable of creating and maintain test automation code. Again, this may vary in some companies that differentiate between the roles. To be a proficient tester regardless of title requires some amount of application domain knowledge. If a person doesn't have an understanding of the domain they are probably spending a lot of time guessing or "trying stuff out" and may completely overlook critical tests.
