PERFORMANCE TESTING
The chief element of identifying risks pertinent to a system is ‘performance testing’. This enables us to provide information regarding stability of system, speed and scalability to our clients. UAB IT Services identifies the relevant processes, tools and data to execute performance testing.
Although mobile devices are still in limited usage as compared to desktop devices for business purposes but the end user still expects high performance on mobile applications. The business transactions taking place on mobile are increasing with the passage of the time and clients are thus calling for more safe and secure applications. The experience incurred by the end-user regarding performance of application depends on server-side performance, client-side performance and network. Client-side performance and network can affect the performance of application at end-user if these two are not working efficiently. The key features to good performance include application architecture, hardware restrictions, UI complexities, online/offline connectivity, third-party APIs used by the application, signal strength, cell coverage, number of hops between server bandwidth and client, connection dropouts and back-haul latency.
UAB IT Services employs tough performance testing measures for mobile web, messaging, GIS and location oriented services. Our mobile performance testing solutions are robust in nature and enables our clients to make the best of their investment in this regard.
Performance testing requires combination of efforts from performance testers, business experts, infrastructure experts and application developers. Furthermore, it requires dedicated environment, expensive tooling and large amount of test data. The demands on tools and resources by performance testing makes it an expensive procedure to be carried out. In order to be carried out successfully it requires a comprehensive plan.
If the objectives of performance testing are unclear it can lead to ambiguity and ultimately the failure of the testing. This can affect the lifecycle of the software. If careful testing is not carried out it can lead to undesired performance of the application generating undesired results thereby leading towards failure of investment. Therefore, here at UAB IT Services our expert consultants assist you in modelling the accurate performance of the applications and implement best test scenarios through effective test strategies.
Specialized skills are required for performance testing for stakeholder coordination and management, workload modelling, requirement elicitation, test tool configuration & installation, result analysis, performance test script and performance optimization/tuning. For test implementation specific skills and test tools are required as well as availability of test data. Lack of any of these elements can render test implementation ineffective.
Here at UAB IT Services we possess expertise in all these areas. UAB IT Services provides its clients with the necessary tools, expertise and test data for test implementation. We help all our clients regardless of whether they are utilizing agile or waterfall methodology. Our consultants perform their duties not as hired services but as a proactive and expert limb of our client assisting them to overcome the shortage of needs and skills in this regard.
Performance tools are required to simulate multiple users in a synchronized manner. There are various performance test tools which cover open source HTTP drivers to commercial drivers simulating the best proprietary CRM/ERP and web technologies. Some tools are found on cloud locations as well so that simulation “outside the firewall” can be tested. Thus, in short there are wide range of tools available in this regard. However, not all tools are relevant to the performance testing as their relevancy depends on the needs of the clients. Besides, there are various licensing models utilized by vendors which can be expensive and restrictive in nature. The choice of a particular tool should be made after a careful analysis. UAB IT Services helps you to choose the most relevant tool as we are vendor certified on various performance testing tools and possess expertise regarding various such tools.
In a waterfall project the performance testing is conducted towards the end. Weeks of testing is required for large scale end-to-end performance testing and its results depend on completion of functional testing environment and production environment. Performance bottlenecks once identified require design and structural changes. Design changes that are conducted later in the lifecycle can be time and cost consuming.
In agile projects the performance testing utilizes a layered approach whereby combination of various tools is utilized. Different stages of development require different performance targets such as feature, code, system level, etc. Performance testing is required within each stage for meeting “done” criteria. System level tests are conducted on end-of-sprint basis for understanding the trends of performance and how overall features can affect the baseline performance. The highly expert professionals at UAB IT Services can help you to conduct performance testing in agile projects.
Applications require various technical, business and operational requirements. Some applications may even require compliance and regulatory requirements. Some applications need validation from end-user perspective against particular criteria. Modern agile projects utilize testing framework for validating end-user requirement earlier in the lifecycle of the project. The end-users belonging to business streams are generally not software experts and can miss validation requirement which can increase the chances of product failure. Therefore, combined efforts may be required to define the approach, scope and extent of acceptance testing. UAB IT Services is keen on helping its clients if they are uncertain about the acceptance test framework or if they need assistance to define the acceptance criteria.
Organizations these days are utilizing business intelligence & analytics applications. Such applications enable the senior management of an organization to undertake correct operational and strategic decisions. For BI applications to work efficiently and render correct output, it must receive correct data. Data error can be dangerous for the performance of the application. This highlights a grave threat to the performance of the applications as data can be found in multiple format and in heterogeneous format. Volume of data and the flow of data can be multi-layered as well. Further challenges can be posed by suitable sized environment, data quality, ETL processes, familiarity of tester with data tools, volume of test data, constant evolution of database, inconsistent front end reporting and regression impact. We work closely with our clients here at UAB IT Services to ensure that their business intelligence applications are thoroughly tested.
E-commerce applications must be available, consistent and performant for meeting the revenue targets. Slow applications can frustrate customers and can increase customer dissatisfaction causing them to look out for other applications. This can affect the overall volume of trade. Web traffic on an application cannot be predicted to absolute certainty as discount or sale can attract unanticipated number of customers.
Peering issues at network level can affect the performance of the website or application in some geographical locations. A growing trend is taking place where it is tried to realize that how applications can cope up with conditions in real world. Performance testing has traditionally been conducted in isolated environments. A growing trend has been to conduct it in real world conditions to match the exact requirements of the real world.
Monitoring the performance of applications allows clients to understand the losses incurred due to poor performance of applications so that performance can be improved. This enables them to implement proactive solutions. There are different tools and methods utilized in this regard. Our professionally trained consultants at UAB IT Services are highly expert in all such tools and methods.
Functional testing is employed for testing the system to ensure that all operational scenarios such as boundary cases and failure paths are meeting the requirements of the business. UAB IT Services works closely with clients to ensure that all functional requirements are met whether they are in user stories, documented form or undefined requirements.
A widely renowned practice of gaining confidence about the quality of the product is validating the product functionality manually. Technical and business requirements are decomposed and test cases and planned and enforced. A real indication of application’s fitness is provided by test results throughout normal or abnormal conditions of operations. Testing techniques include both formal and informal testing techniques. UAB IT Services offers a complete manual testing support to different types of applications by utilizing various technologies and methods to support the products of the client.
A critical success factor for any application is the functional correctness of application over wide variety of operating conditions. Rapid adoption and development of new web designs, web standards, user interface technologies and varied nature of capability of mobiles with regard to browser, hardware, platforms and operating systems has further complicated the performance of the applications. Extensive and exhaustive testing can be expensive and unrealistic. A well-co-ordinated strategy is required to ensure the quality of the product throughout varying configurations. Here at UAB IT Services we ensure that the products of our clients can operate efficiently throughout these varying features.
The business environment is rapidly changing these days and is becoming highly competitive. Software development and advancement is taking place rapidly. Applications these days are expected to be cloud friendly. In order to achieve this newer adjustments in software are required from monolithic style to loosely coupled style. But it must be responsive in nature to support the same logic of business. Therefore, regression testing must be multi-layered for supporting the changing demands of business. Our consultants here at UAB IT Services can help you beyond your expectations in this regard.
