software testing company Why Should Software Be Load Tested? Posted By: QATestLab If the software is at the final stage of its life cycle and already has passed almost all the main stages of its verification, the time for load testing comes. Many have heard this term, but not everybody knows what it means. So, the load testing is aimed at confirming that the system, being under continuous and steadily increasing stress, retains its performance. Such testing is carried out until the program reaches its threshold limit. Sometimes testers prefer to complement the load process with automation components, as it helps to simulate conglomerations of processes from a large number of simultaneous users. Often this technique is also called a subspecies of stress testing as a mutual goal of both these kinds is the endurance testing. Most of those who belong to the software testing environment have quite a contradictory opinions regarding to the use of load testing. Let’s start with the fact that this method does not apply to functional testing. In fact, it is an attempt to exactly reproduce the process of alleged disposal of a product by the majority of users who at one and the same time perform some processes causing the increase of a load on software.


software testing company To What Software Aspects Are Automated Tests Most Sensitive? Posted By: QATestLab Automation is widely utilized nowadays during load testing, regression testing, security testing, etc. It considerably diminishes time and efforts, needed on verifying an application, if applied correctly. Few decades ago automated testing of programs and hardware required much equipment and could be carried out only by certain companies. Modern market offers a wide choice of paid and free tools for tests automation. Most Of Such Tools Allow Testers To: record and play back the user actions; imitate the user interaction with the software; imitate simultaneous interaction of many users with the application; test the system via the user interface, etc. Such tools are helpful for programmers and testers. Unfortunately, tests created by means of them are fragile, their maintenance is time-consuming. Automated tests may fail even after the slightest changes in the program. Most of All Automated Tests are Sensitive to Changes In: The system functioning. When the program functions change, the automated tests involving those functions fail, no matter what tool or method was applied for their creation. The tests will also fail if the way of the function performance is altered, for example, the actions run faster, or the sequence of actions became different. The user interface.

Each type is unique and requires special approaches and methods in order to develop and release successful products. Web applications are more exposed to various attacks than desktop ones due to the nature of web technology. Web software products, unlike desktop ones, are always multiuser, accessible from different places and support simultaneous interaction with many users. These features make web sites and applications a target for various cyber-attacks more often than desktop software are attacked. Among Prevalent Types of Attacks on Web Applications Are: – SQL injections; – cross site scripting. Attacks of those types are applicable only for web software. By means of them hackers can steal sensitive data or perform other malicious actions. SQL injections are utilized when the user inputs are in the form of SQL queries to the program database. A hacker can inject some SQL commands into the user inputs and this way get an unauthorized access to the information stored in the database. If such an attack was unsuccessful, the needed data could be taken from the error message. Sometimes error messages contain the user password or other confidential information in clear.


software testing company Performance Testing: An Experimental Approach To Improve Web And Mobile Productivity Posted By: Pooja Runija Introduction The performance of a product plays an important role in the quality of the product, including software and mobile applications. Quality is the key factor which is responsible for branding and success of the product, followed by more business for the organization. Performance is an important term that measures, or determines, the performance of an application or an application component. For example, a user can’t wait for a long time in a website to get the cricket live score, or to see the list of items in an online shopping store. Rather, he/she switches to other sites that render the required information much faster. The overall credibility of products is highly influenced by the performance, along with its functionality and features. Why to do Performance Testing? The performance requirement takes top priority among regulated and highly critical applications, like health care and financial products, because no one wants to put up with a slow performing, unreliable site in cases of purchasing, health, online test taking, bill payment, etc. With the internet being so widely accessible, it is easier to lose clientele than gain them and performance is a key game changer to satisfy the customers.

web load testing Software Stress Testing Protects Enterprise Apps Posted By: Srikrishna Das An organization has option to evaluate the quality of an enterprise application through both manual and automated software testing options. But the test strategy must consider evaluating both functional as well as non-functional aspects of the application. Along with the look, feel, features and functionalities of the software, it is also important to test beyond its normal operational capacity. Software stress testing is used to determine the stability and operational capacity of an application. The key objective of the non-functional testing is to ensure that the enterprise apps do not crash in the live environment due to insufficient memory, disk space or other computational resources. Along with considering the correct behavior of the enterprise application under normal circumstances, the testing further aim to protect it in production environment by emphasizing on availability, robustness and error handing under a heavy load. How to Protect Enterprise Apps in Live Environment through Stress Testing Finds Critical Memory Problems Often enterprise apps crash due to lack of adequate memory. But the flaws will not reflect in a single instance. So stress tests need to be carried out constantly to find the critical memory problems and concurrency bugs.
