software testing

In software testing, features and functionalities supported by a software system are not the only concern. The performance of a software application, like its response time, reliability, resource, usage, and scalability, is essential for customer satisfaction. The goal of Software Performance Testing is not to find bugs but to eliminate performance bottlenecks.   This article provides insights into one of the tricky non-functional testing types that usually gets overlooked during the software development lifecycle. And how we at Q-Pros plan, design, and execute various performance evaluation techniques the right way without enduring a high cost.  What is Software Performance testing?   Performance Testing is done to provide stakeholders with information about their application regarding speed, stability, and scalability. More importantly, Performance Testing in software testing is to uncover what needs to be improved before the application goes to market. Without Performance Testing, the software is likely to suffer from issues such as running slow while several users use it simultaneously, inconsistencies across different operating systems, and poor usability.      Software Performance testing will determine whether the software meets speed, scalability, and stability requirements under expected workloads. Applications sent to the market with poor performance metrics due to nonexistent or low-quality performance testing are likely to gain a bad reputation and fail to meet expected sales and adoption goals. Also, mission-critical applications should be performance tested to ensure they run for longer periods without deviations (i.e., soak testing).  According to Dunn & Bradstreet, 59% of Fortune 500 companies experience an estimated 1.6 hours of downtime every week due to an unhandled high load. Considering the average Fortune 500 company with a minimum of 10,000 employees is paying $56 per hour, the labor part of downtime costs for such an organization would be $896,000 weekly, translating into more than $46 million per year. Only a 5-minute downtime of Google.com (19-Aug-13) is estimated to have cost the search giant as much as $545,000.    Why do we need Software Performance testing?   Performance optimization of various products, platforms, devices, and technologies. Shifting from conventional models to continuous delivery. Limited timelines and budgets while providing high-quality service. Maximizing performance of the existing infrastructure. Early detection of system performance.   Common Performance Problems   Most performance problems revolve around speed, response time, load time, and poor scalability.   Speed is one of the most important attributes of an application. A slow-running application (i.e., high time-to-interact) will lose potential users. Performance testing guarantees that an app runs fast enough to keep a user’s attention and interest.   Here is a list of the most common performance problems:  Long loading time - Load time is normally the initial time it takes an application to start. This should generally be kept to a minimum. While some applications are impossible to load in under a minute, Load time should be kept under a couple of seconds if possible. Poor response time – Response time is the time it takes from when a user inputs data into the application until the application outputs a response to that input. Generally, this should be very quick. Again, if users wait too long, they lose interest. Poor scalability – A software product suffers from poor scalability when it cannot handle the expected number of users or if the application does not accommodate a wide enough range of users. Bottlenecking - Bottlenecks are obstructions in a system that degrade overall system performance. Bottlenecking is when either coding errors or hardware issues cause a decrease in throughput under certain loads. Bottlenecking is often caused by one faulty section of code. The key to fixing a bottlenecking issue is to find the section of code that is causing the slowdown and try to tune it. Bottlenecking is generally fixed by either fixing poor running processes or adding additional Hardware. Some common performance bottlenecks are: CPU utilization Memory utilization Network utilization Operating System limitations Disk usage   Types of Software Performance testing We Cover   Load testing – checks the applications' ability to perform under anticipated user loads. The objective is to identify performance bottlenecks before the application goes live.  Stress testing – involves testing an application under extreme workloads to see how it handles high traffic or data processing. The objective is to identify the breaking point of an application. Soak testing – is done to validate the software's ability to handle the expected load over a long period. Spike testing - tests the software's reaction to sudden large spikes in the load generated by users. Volume testing – Under volume testing, a large number of Data gets populated in a database, and then the overall behavior is monitored. The objective is to check the performance under varying database volumes. Scalability testing - The objective of scalability testing is to determine the software application's effectiveness in "scaling up" to support an increase in user load. It helps plan capacity addition to your software system. This is critical with cloud hosting.   In Conclusion   Software Performance testing is essential for companies who wish to provide an excellent long-living digital service. Certain types of clients would include governmental and semi-governmental agencies as well as privet institutions that rely heavily on online mediums for outreach.   Q-Pros works and continues to make progress in elevating performance for our clients.

Artificial Intelligence (AI) is no longer a futuristic concept confined to science fiction; it's a transformative force that's reshaping our world across various domains. In this article, we'll delve into the fascinating realm of AI, exploring its history, core principles, current applications, and the potential it holds for the future. The Genesis of Artificial Intelligence Artificial Intelligence, as a field of study, was officially coined in 1956, but its origins can be traced back to early philosophical debates about human cognition. Early pioneers like Alan Turing and John McCarthy laid the foundation for AI by proposing concepts such as the Turing machine and the Dartmouth Workshop. AI's development took significant strides in the 20th century, with the creation of expert systems and the development of rule-based AI. However, AI's progress was marked by periods of enthusiasm followed by "AI winters" where research slowed due to high expectations and unmet challenges. Key Concepts in AI Artificial Intelligence operates on several fundamental principles, including: Machine Learning (ML): ML is a subset of AI that focuses on creating algorithms and models that enable computers to learn from and make predictions or decisions based on data. Neural Networks: Inspired by the human brain, neural networks are a fundamental component of deep learning, allowing Artificial Intelligence systems to process data, identify patterns, and make complex decisions. Natural Language Processing (NLP): NLP enables AI to understand, interpret, and generate human language, giving rise to applications like chatbots and language translation services. Computer Vision: Artificial Intelligence systems use computer vision to "see" and interpret images or video, powering applications from facial recognition to autonomous vehicles.
