Load Testing Importance

1211 Words5 Pages

Introduction and Importance

Software development companies dedicate a substantial amount of resources and manpower for the development of applications according to requirements specified by enterprises or individuals. However, subsequent to development of such applications/software, companies are required to ensure that such software/applications perform in accordance with the client's requirements. To ensure that any and all bugs in the software are identified prior to the deployment, various testing procedures are implemented by the IT industry. The importance of this is directly related to the ability of software to measure up to its potential. If the new software is unable to perform the task it was designed for, the client might face …show more content…

By using load testing, developers can attempt to determine the reason for slow performance of software. The common reasons for such slow response commonly include load balancing between multiple servers, client-side processing, network congestion/latency, available database service and/or bugs in the application server(s) or software. The use of load testing is recommended for software/applications, which are subjected to SLA (service level agreement) for ensuring that the software is capable of supporting multiple users. As the procedure simulates an increase in system load by using multiple virtual users, various software are currently available to carry out load testing. Some of the leading load-testing tools used by developers globally are IBM Rational Performance Tester, Apache JMeter, LoadRunner etc. Additionally, a load testing tool commonly favored by software testing companies in India is available as part of the Visual Studio Ultimate Edition of …show more content…

The key function of regression testing is to ensure that the use of a patch or upgrade does not lead to the introduction of a new bug into the existing system. Additionally, regression testing helps ensure that the changes in one section of the software do not induce changes in another part of the software's code. Some of the commonly applied regression testing methods include the use of earlier tests to check for alterations in program operation and the search of any previously fixed bugs, which had re-emerged subsequent to introduction of the new code. Fixed bugs in software often re-emerge and regression testing is one of the leading methods to ensure that such re-emergence is identified and easily controlled before any lasting damage occurs. Software development companies repeatedly perform regression testing of software/applications after any change in coding such as use of patches etc. to ensure that the functionality of the application is unimpaired. Such repetitive testing is usually automated by using an external tool such as Bamboo, TeamCity, Jenkins, Hudson, Tinderbox or BuildBot. This type of testing is generally performed by the QA team in case of leading software development companies, however, smaller

    The difference between the two and three-tier client/server configuration, are the tiers (layers) that make up the systems. In a two-tier system you have a client and a server, each has the capability of doing the processing for the application (Brown, DeHayes, Hoffer, Martin, & Perkins, 2012). The software is loaded on the client computer, and access the data server directly. In a three-tier system, there is an additional server/computer between the client and data server; this third component contains the business logic or processing for the application (Brown, DeHayes, Hoffer, Martin, & Perkins, 2012; Luke, n.d.). A three-tier configuration could be a web-enabled business application.

    Standardized Testing While can be beneficial, standardized testing isn't improving American education. Standardized testing evaluates only the individual performance of a student instead of the overall growth of a student over the course of a year. In my opinion, Standardized testing is not enhancing education in America. Not all students who are smart and take in all the information test well. For instance, there are many people who simply do not perform well on tests.

    The Benefits of Optional Standardized Testing According to the data of William Hiss, a previous dean of admissions for Bates College, “students with higher grades and modest test scores did better in college than students with lower grades and higher test scores” (Sheffer). This proves that grades are more accurate predictors of a student's academic success. There are many benefits of making standardized tests optional or not requiring them at all. Standardized tests are a biased way of measuring academic talent.

    INTRODUCTION The application of information, expertise, tools, and procedures to project activities to meet the project requirements is known as project management (PMBOK 2008). Alternatively, project management is the process in which projects are well-defined, planned, supervised, organized and conveyed such that the agreed features and requirements are fulfilled (APM BOK 2006). Success of IT projects is very much dependent on providing the anticipated product at the projected time, within budget, its desired performance levels, acknowledged by the client, offering at least the minimum agreed functionality i.e. meeting customer satisfaction, and delivering the promised benefits (Dalcher and Brodie, 2007).
