<h2 id="h-the-beginning">The Beginning</h2>



The year kicked off with a mix of excitement and concern for me as a Nigerian who just completed her National Youth Service program, and was not sure of what next. Applying for the Graduate Trainee Program at Helium Health as a Quality Assurance Engineer marked the beginning of my journey in the field of software testing. Working in a health tech company, and being in charge of ensuring that the digital health solutions are reliable and of high standards was the highlight of the year 2023.&nbsp;



Before I became a QA Engineer, I never knew that a field such as QA or software testing existed, as opposed to the popularity of other tech areas like Web Development, Product Design, and others. Although I was a bit skeptical about the niche because I was yet to fully understand the role that QA engineers and software testers play in the software industry, now, I can confidently say that “Software testers and Quality Assurance Engineers are the unsung heroes in software development.”



<h2 id="my-experience-as-a-quality-assurance-engineer">My Experience as a Quality Assurance Engineer</h2>



My experience in the field of QA has been nothing short of amazing, definitely came with a lot of challenges. However, I would say that my already established background in Software Development as a Front-End Developer made my journey easier and more enjoyable. I took some courses to fully immerse myself in the niche, a big shoutout to Tarek Roshdy, who I believe is one of, if not the best tutor on Udemy when it comes to Software Testing. I found his style of teaching really enjoyable and I really love how he is able to explain concepts in a way that makes it easy for even beginners to understand.&nbsp;



Fast forward to when the Senior QA Engineer started assigning projects to me, I felt like I was not ready to start taking on projects, which was one of the lessons I learnt that you can never validate your learning and knowledge if you do not apply them. Writing test cases definitely shaped my way of thinking because one thing I learnt is that, as a tester, you have to put yourself in the shoes of every potential user of an application or product, to achieve optimal results.



Also in the year 2023, I got a job opportunity as a Freelance Technical Writer at Testsigma, and this also marked the beginning of my career in Technical writing. Writing on the different blog articles increased my level of knowledge and research in software testing, because as a technical writer, you have to convey technical information in the simplest and uncomplicated way possible.



<h2 id="my-wins">My Wins</h2>



Celebrating wins is an integral part of my QA journey. The wins of 2023 were not just moments of celebration, they were also milestones that signaled the triumph of innovation, hard work, and resilience. In 2023, I was offered a full-time employment at Helium Health as a Junior Quality Assurance Engineer after the six-month Graduate Trainee program. At the end of the program, I could proudly say that I had gained significant skills in <a href="https://testsigma.com/guides/software-testing/" target="_blank" rel="noreferrer noopener">software testing</a>. I could write and execute test cases, bug reports, and test reports and also conduct performance, regression, and usability testing. This might not seem like a lot of progress, but I count it as one because I knew where I started from, and it was only evident that I had put in a lot of work.



Collaboration emerged as a key theme in my wins column. Creating efficient tools for cross-functional collaboration—especially with developers—led to a more unified approach to quality assurance. The testing team was able to establish a symbiotic relationship with the development team, resulting in faster bug resolution and smoother integration of new features.



Perhaps one of the most satisfying wins was the successful execution of a complex performance testing strategy. Simulating real-world scenarios and stress-testing applications under heavy loads revealed potential bottlenecks and vulnerabilities. Mitigating these issues before deployment not only enhanced the overall user experience but also prevented costly downtimes, marking a significant win for both the testing team and the organization.



<h2 id="my-failures">My Failures</h2>



In the pursuit of triumphs, failures are inevitable. Several testing approaches that looked good on paper fell apart when confronted with practical situations. Also as someone who was still struggling, I found it difficult to understand some of the tasks given to me by the Senior QA Engineer. There were times when it would take a long time for me to complete certain tasks because it took a while for me to understand the concepts. I remember vividly when he asked me to conduct a load test on a certain application. I had to utilize a lot of resources to get the job done, however, the good feedback I got from him was more than enough to compensate for the tons of work I had to do. Acknowledging failures became a stepping stone for improvement for me. Embracing failure not as a setback, but as a guide to refinement, proved to be a key takeaway from the year.



<h2 id="my-learnings">My Learnings</h2>



Amidst the ups and downs of experiences, the wins, and the failures, the true essence of 2023 lies in its profound lessons. Each challenge, setback, and triumph became a chapter in the ongoing saga of growth and self-discovery.&nbsp;



I learnt that adaptability is the cornerstone of successful testing in an ever-changing technological landscape. In a field where rapid technological advancements can quickly rewrite the laws, being adaptable and welcoming of change has become more than a survival ability. One lesson ingrained in my professional ethics is the capacity to adapt approaches, tools, and strategies in reaction to evolving trends. Continuous upskilling and staying abreast of industry trends became non-negotiable, ensuring that I remained at the forefront of cutting-edge testing practices.



I also learnt that my relationship with people will determine how good I am at my job, because if you are not productive with people, there is a limit to how far you can go.



The remote work revolution demanded a recalibration of communication strategies. Navigating the nuances of virtual collaboration became an art in itself. Learning to convey complex testing scenarios and insights effectively through digital channels wasn&#8217;t just a necessity for me, it was a revelation in the power of clear, concise communication, a skill that extended beyond testing scenarios into everyday professional interactions.



Perhaps the most transformative learning of 2023 was the recognition that being a QA engineer wasn&#8217;t just about finding bugs, it was about being a proactive contributor to the entire software development lifecycle. Shifting from a gatekeeper mentality to a collaborative partner in quality became a paradigm shift that altered the way I approached testing.



<h2 id="conclusion">Conclusion</h2>



As I pen down my reflections on the year 2023, I realize that being a tester is not just a profession but a dynamic journey of growth, resilience, and perpetual learning. Each experience, win, fail, and experiment has contributed to the evolving narrative of my testing odyssey. Here&#8217;s to embracing the challenges and triumphs that lie ahead, as I navigate the ever-shifting currents of software testing in the years to come.

In this article, we will delve into the intricacies of load testing and stress testing, uncovering their fundamental differences and shedding light on how they contribute uniquely to refining software performance.



<h3 id="what-is-load-testing"><a href="https://testsigma.com/guides/load-testing/" target="_blank" rel="noreferrer noopener">What is Load Testing?</a></h3>



Load testing is a type of performance testing that focuses on the behaviour and responsiveness of an application under normal load conditions. It simulates the expected workload on the application, such as the number of concurrent users or transactions, to evaluate its performance metrics. 



Load Testing helps you gauge the breaking point where performance remains optimal, and user experience doesn&#8217;t take a hit. It helps identify performance bottlenecks, uncover any inefficiencies, and ensure that the application can handle the projected load without compromising its speed, stability, or user experience.



<h3 id="what-is-stress-testing"><a href="https://testsigma.com/blog/software-stress-testing/" target="_blank" rel="noreferrer noopener">What is Stress Testing?</a></h3>



Stress testing is another fundamental performance testing technique aimed at assessing an application&#8217;s robustness and reliability under extreme and challenging conditions.&nbsp;



Unlike load testing, stress testing pushes an application beyond its normal load conditions.&nbsp;



The primary objective of stress testing is to identify the breaking point of the system, understand how it behaves under extreme stress, and evaluate its ability to recover gracefully from any failures or crashes.&nbsp;



This type of testing helps uncover vulnerabilities, bottlenecks, and weaknesses in the application&#8217;s architecture, enabling developers to fortify the system and enhance its overall performance and stability.

<h2 id="load-testing-vs-stress-testing">Load Testing Vs Stress Testing &#8211; Summary</h2>



Load testing is primarily focused on assessing the performance of a system under anticipated or typical user loads. The primary objective is to ensure that the system functions smoothly and efficiently under regular, expected conditions. Think of it as evaluating how well your car runs during everyday city driving or highway cruising.&nbsp; Load testing helps answer questions like:



<ul><li>Can the application handle the expected number of users without slowing down?</li><li>Is the system responsive under typical user interactions?</li><li>Are the response times within acceptable limits under normal usage?</li></ul>



In essence, load testing assures that your application will perform adequately when it encounters the expected traffic load, ensuring a good user experience under usual circumstances.



On the flip side, stress testing is all about pushing the system to its limits and beyond. The main aim here is to evaluate how well the system copes with extreme and adverse conditions that exceed its standard operational boundaries. Imagine testing how your car handles the harshest off-road terrain or extreme weather conditions. Stress testing seeks answers to critical questions such as:



<ul><li>What happens when the system faces an unexpected surge in user traffic?</li><li>How does the application behave when hardware components fail unexpectedly?</li><li>Can the system recover gracefully from sudden and intense stress?</li></ul>



Stress testing goes beyond everyday scenarios to identify vulnerabilities and weaknesses that could lead to system failures under exceptional circumstances. It&#8217;s like stress-testing a bridge to ensure it can withstand the most severe earthquakes or storms.



<h2 id="load-testing-vs-stress-testing-what-are-the-best-practices">Load Testing VS Stress Testing &#8211;What are the Best Practices ?</h2>



Some of the best practices for load and stress testing, or any type of performance testing, are as follows,



<ul><li>Always begin with a performance baseline. A solid baseline is crucial to identify and measure performance bottlenecks for improvements or declines over time.</li><li>Prioritize your performance tests since covering every user workflow is impractical, given the various types available. Focus on the most essential workflows initially.</li><li>Integrate performance testing into your CI/CD pipeline. Run performance tests as part of <a href="https://testsigma.com/continuous-integration" target="_blank" rel="noreferrer noopener">continuous integration</a> and deployment to ensure continuous testing. Ad hoc approaches are rarely effective in practice.</li><li>Allocate time for addressing any performance issues. Performing performance tests in the early stages of development allows much time for fixing issues before the product goes to production. Implementing a shift left approach has a remarkable impact on testing.</li></ul>
