Four Pillars of Quality Engineering to Support Flawless Customer Experience

Allow me to remind you of that surge of impatience you must have felt as a customer the last time you interacted with a digital product and a swipe, or a click didn’t work the way you wanted it to. Perhaps the thought of switching to a competing brand crossed your mind.

To steer clear of that possibility in the case of your brand, your organization would do well to take the Quality Engineering (QE) route to ensure excellent customer experience. After all, fast response times have never been more important,

First things first, let’s understand what QE is all about and why you need it today.

What is Quality Engineering and Why do you need it?

Quality Engineering (QE) is a discipline that ensures that digital products are designed and tested to meet user needs effectively. It’s a proactive approach that integrates quality assurance from the initial stages of development, focusing on enhancing performance, security, and user experience.

QE is vital for your business as it:

• identifies potential issues early
• saves time and resources
• boosts customer trust

QE includes regression testing, mobile compatibility testing, performance testing, data testing, and so on.

If your business prioritizes QE, it can deliver superior software products that stand out in a competitive digital landscape, ultimately driving success and innovation.

In this digitally empowered world we inhabit, modern software engineering is ushering in cutting-edge technology to enhance conventional software product development. Quality engineering services have been playing a vital part in these exhilarating developments.

In a nutshell, QE solutions involve optimal quality assurance, monitoring, and predictive analytics, and are well-suited for any organization with a futuristic vision.

Now let’s focus on the four pillars of QE.

Four Pillars of Quality Engineering

In this blog, I am going to acquaint you with four pillars i.e., key aspects of quality engineering in software testing that are well-equipped to support immaculate customer experience:

Accurate test automation

If your business is one with mission-critical technology systems, it requires software testing via a test framework that is consistent, efficient, reusable, and modular.

Test automation serves up a large platter of advantages for your business. First, it brings quicker validation for phases in the development of your product. Next, it detects bugs early in the development phase which is a great sign for the efficiency of your team. There’s less testing effort required and on the other hand, it improves the accuracy of testing.

Overall, it’s a highly reliable testing methodology compared to manual testing. That’s a deliciously loaded platter, wouldn’t you agree? Also, here’s a fun fact: AI can learn from various user flows and generate test cases on the basis of actual user data.

Here are some types of test automation you should know about:

• Framework development
• UI test automation
• Tool feasibility
• API test automation

Test automation tools and technologies include Selenium WebDriver, TestComplete, Karate, Postman, TestLink, TestRail, Appium, espresso, AzureDevOps, Jenkins, Java, and Python.

Powerful performance testing

This type of software testing ensures that a system or an application performs well in terms of whether it is stable and responsive. In case there are troublesome speed issues such as long load times and slow responses, they are addressed efficiently, which ultimately amounts to a smooth-as-silk user experience!

Performance testing measures the quality attributes of the system such as scalability, reliability, and resource usage. It can entail performance benchmarking, performance load, volume, stress, and endurance test as well as effective reporting of performance results and recommendations. Interestingly, it also goes by the memorable nickname of ‘perf testing’ – hinting at its capacity for perfection.

Examples of performance testing tools include JMeter, LoadRunner, and StresStimulus.

Here’s a little tip for when you begin your testing tour: It is a great idea to test often and test early. This whitepaper details the value of performance testing and explains Nitor’s carefully thought-out strategy.

Dynamic data testing

I’m sure you are aware that data is an asset in these times, as it is necessary to fuel important business decisions for enterprises.

What’s more, a database is essential for any software application. Put simply, this resource needs to be tested and validated via database testing. Database testing in the process of quality engineering includes ETL testing, analytical testing, BI report testing, data warehouse testing etc.

Database testing does wonders in software testing because it helps you understand whether information stored in a database is valid or not, in the first place. It also:

• saves aborted transaction data,
• prevents data loss, and
• wards off unauthorized access.

Examples of tools include QuerySurge, Metallion, and ETL Validator. Data testing can be done using SQL queries, Java, C# or Python.

Robust security testing

I must inform you that it is a myth that only banking applications or products of large companies necessitate security testing. Every company, regardless of whether it is in the banking domain or not, requires security testing.

According to reports, the cause of the leaking and hacking of sensitive information can be attributed to compromises on security testing.

The fact is that security testing secures the confidential data of all applications. To safely avoid irreparable loss to your organization, do consider opting for robust security testing mechanisms of quality engineering, which have attributes like:

Some examples of security testing tools are: NMAP, Nessus, testSSL, Zap, Burp Suite, APK, and D2jar.

So, there you have it (or rather, them) – the four sturdy pillars of quality engineering in software testing to hold up the construction of your dreams – by which I mean, the business that is driven by impeccable customer experience.

Perhaps your mind has now created a distinct image of how quality engineering solutions can strengthen the business of your organization, built as they are based on the principles of quality assurance and the magic of AI.
