Quality Assurance In Software Engineering
Quality Assurance In Software Engineering – What do NASA, Knight’s Capital Group and Heathrow Airport have in common? All these guys know from experience what a really costly software bug is. They learned the hard way how a small software glitch can lead to big losses. What hurts the most is that these errors can easily be avoided with timely software testing. Therefore, today we will talk about why the testing phase is crucial and how a QA engineer can save you money and your reputation.
If you ask us “Why is software quality control important?”, the answer is simple: a modern digital solution must be carefully reviewed and tested. Otherwise, strange things will happen. In 1998, NASA sent the Climate Orbiter to Mars. Unfortunately, the $125 million spacecraft was lost in space because NASA engineers could not convert to metric units.

In 2012, Knight’s Capital Group lost $460 million in 45 minutes due to the misuse of trading algorithms on one of Knight’s production servers. Heathrow Airport ran into trouble after opening a new baggage handling system when thousands of bags were left behind and hundreds of planes were stuck, causing mass flight cancellations. This happened because the system was not tested for different scenarios (for example, when passengers claim their luggage because they left documents inside), so it was overloaded and crashed.
The Quality Assurance Engineer Role In The Product Team
But we are not here for moaning and groaning: even such costly failures are not a reason for despair, but a lesson for all companies that they should take care to test products or services before launching them on the market. No matter how good a developer is, he can still make mistakes. Therefore, a QA engineer is an indispensable member of any software development team.
While quality control is generally a process focused on the final product, quality assurance is a process-focused set of activities aimed at preventing software defects before production begins. Let us note that the responsibilities of QC and QA experts are often mixed, and in the world of IT industry we have a kind of universal expert called QA engineer.
Some QA engineers describe their work as “thankless,” “often overlooked by the pompous IT industry,” and “having a terrible problem with marketing.” This is often true and of course unfair, although the importance of the quality assurance process cannot be overstated. So what does a quality control engineer do?
There are many reasons why a particular change works on a developer’s machine but fails on others, including a different machine/system environment, a hardcoded directory or path in the code, missing dependencies, and so on. The IT world may be at the peak of software development difficulties right now: there are more variables, OSes and processors today than ever before. And the common task of developers and QA is to create cross-platform software that works perfectly on different devices with different screen sizes, operating systems and their versions. Busy bees.
The Role Of A Quality Assurance Engineer: A Comprehensive Guide
Perhaps the most accurate explanation of why this is: good quality control tests are essential to ensure accurate, reliable and rapid software development and deployment.
We note that a QA engineer is very necessary before, not after, project development begins. Debugging is not such an exciting process and the crucial task is to avoid mistakes, define product standards and make a good development plan before it starts.
We have already mentioned failures with business giants like NASA. Some software bugs even happen to tech superheroes like Apple. In its rivalry with Google, Apple decided to create its own map application as an alternative to Google Maps to replace it on iOS devices. The company released the project in 2012 and caused an outcry: entire lakes, bridges, tourist attractions and stations were incorrectly marked or missing on Apple’s maps. The Washington Monument was across the street, while New Zealand’s main train station moved to the middle of the Pacific, and so on.
Connecting the data that underpins map apps requires a lot of manual labor — something Google has had for years and Apple hasn’t. Step by step, Apple solved these problems, but it obviously left an unpleasant aftertaste for users. For the most part, no one is safe from problems. But our main task is to avoid possible mistakes and make sure that we test every possible detail before the product is released.
What Are Quality Assurance Engineers (qa Engineers)? Definition & Faq
If this happened to giants like Apple and NASA, you need to stay calm and be vigilant with your QA team.
STLC stands for Software Testing Lifecycle. It is an algorithm in which every action is performed systematically. Here is a diagram showing the sequence of the six process phases.
QA engineers have saved many projects. In addition to saving valuable time, QA also saves money for customers. Although the project duration is directly proportional to the invoice size and fewer mistakes means less work time.
Freshcode QA engineers get behind the table in the requirements stage to create the most effective collaboration and vision for the future product/service. In addition, we have cases where our QA engineer managed the project as a Business Development Manager in addition to his direct duties.
Introduction To Software Quality Assurance & Testing
Every Freshcode software development project has a QA engineer. But the exception proves the rule. Once upon a time, one of our customers found it unnecessary to get a QA team. His project X (out of respect for our clients we will not reveal their names) was developed by 3 people. As for testing, responsibility for quality assurance processes was delegated to developers based on the client’s assignment. Given that the developer’s hourly rate is significantly higher, this decision resulted in more than $6,000 over the estimated budget. When the iterative cost estimate for the described project reached $25,000, the deliverables were budgeted at $31,100.
In addition, the estimated time frame was shifted by 5 weeks. So the February release date was missed and pushed to March. In March, the release date was changed to April due to the need for a new suite of automated tests. The result was release delays, budget overruns, and unhappy customers who didn’t get the features they expected on time.
Requirements and tasks were defined without proper test documentation, and it was difficult to quickly understand the described cases, errors and remediation processes. Undoubtedly, having a software QA engineer who can drive the process, create clear documentation, link all parts and make proper automated tests can be a great leverage for faster completion.
Freshcode QA engineers have two main tasks: ensuring the quality of the product/service by monitoring the progress of the software and thoroughly testing each function. We strive to be a multifaceted team to identify and resolve any issues as quickly as possible. Our project managers work with the QA team, keeping them informed and aware of any changes in requirement or new features or changes in schedule. In turn, QA engineers provide feedback to developers about what needs to be fixed or rewritten. The error report describes the type of device, OS version, description of the operation performed and errors encountered during execution, etc. According to a PractiTest study, the bug report is the most common test documentation used by companies, with 79% reporting its use in 2019.

The Freshcode QA team provides detailed reports that are generated for each run. The report includes screenshots and videos that show what needs to be fixed. This way, developers can quickly find the bug and fix it. We at Freshcode use Jira software to track and report bugs.
Here is an example of a section of the bug report document related to developing a reservation website (configuring hotel reservation settings, adding check-in and check-out dates).
As we already mentioned, QA is a multi-handed and versatile professional in the team. But let’s identify the top 3 skills that we think are the most important.
In short, the success of your future software product depends entirely on software quality control. QA engineers should be involved early in the process when it is crucial to identify risks, adjust requirements, review all technical details and advise on more appropriate options where possible. QA can handle it.
Software Quality Assurance Engineer Skills: Definition And Examples
It is not a good idea to give QA responsibility to developers. It just doesn’t work well. Developers who work in the team make only a part of the project advertising, they often miss the overall picture. Sometimes they misunderstand requirements or leave errors that cause delays. It’s easy to overlook your own mistake through tired eyes, isn’t it?
The developer’s mission is to implement the given functions, not to control the client’s ideas. This is a superpower of QA engineers and what he is good at.
