Testování výkonu LTE infrastruktury / Performance Testing for LTE InfrastructurePolanka, Martin January 2018 (has links)
In the past few years, new standards of telecommunication networks brought new approaches to the internal architecture and introduced new components. One of them is the PCRF server component which manages an allocation of bandwidth for all user devices, therefore, it is a performance sen- sitive application. Yet there are no suitable smart traffic generators for such server and there is no comprehensive study of implementations. Based on the server provided by one of the major Czech telecommunication providers, the traffic generator for real scenarios and performance testing was designed and implemented. In addition, the statistics collection from the server was realized with the use of instrumentation. Both of these parts were put to- gether in the form of testing framework which was used for measurements of the designed test cases. The results from the measurement were evalu- ated and describe the behavior of the server in a real-life utilization and also under heavy load. Based on the evaluation, the provider can improve the server implementation and perform further analysis. The traffic generator can be extended to support more test cases and even reused by different telecommunication providers. 1

Examining Various Input Patterns Effecting Software Application Performance : A Quasi-experiment on Performance TestingCharla, Shiva Bhavani Reddy January 2016 (has links)
Nowadays, non-functional testing has a great impact on the real-time environment. Non-functional testing helps to analyze the performance of the application on both server and client. Load testing attempts to cause the system under test to respond incorrectly in a situation that differs from its normal operation, but rarely encountered in real world use. Examples include providing abnormal inputs to the software or placing real-time software under unexpectedly high loads. High loads are induced over the application to test the performance, but there is a possibility that particular pattern of the low load could also induce load on a real-time system. For example, repeatedly making a request to the system every 11 seconds might cause a fault if the system transitions to standby state after 10 seconds of inactivity. The primary aim of this study is to find out various low load input patterns affecting the software, rather than simply high load inputs. A quasi-experiment was chosen as a research method for this study. Performance testing was performed on the web application with the help of a tool called HP load runner. A comparison was made between low load and high load patterns to analyze the performance of the application and to identify bottlenecks under different load.

No. of bitstreams: 0 / Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) / Foram elaborados e implementados testes de controle de qualidade em equipamentos de angiografia por subtração digital. Estes testes foram baseados em normas nacionais e internacionais e foram implementados em cinco equipamentos de três instituições diferentes. Estes testes avaliam os parâmetros de desempenho dos equipamentos e são utilizados para a determinação da taxa de kerma no ar na entrada da pele do paciente e do corpo clínico. Os testes foram realizados utilizando dispositivos, simuladores de pacientes e câmaras de ionização. Os testes convencionais e do sistema de subtração digital indicaram que os equipamentos avaliados encontravam-se em bom estado de desempenho. Os testes para verificação da taxa de kerma no ar indicaram que um dos equipamentos avaliados apresentou altas taxas de kerma no ar na entrada da pele do paciente em modo fluoroscopia. Este problema foi notificado, e as devidas providências foram imediatamente tomadas pela gerência do hospital. / Dissertacao (Mestrado) / IPEN/D / Instituto de Pesquisas Energeticas e Nucleares - IPEN/CNEN-SP / FAPESP:99/06803-9

Comparative Study of Performance Testing Tools: Apache JMeter and HP LoadRunnerKhan, Rizwan Bahrawar January 2016 (has links)
Software Testing plays a key role in Software Development. There are two approaches to software testing i.e. Manual Testing and Automated Testing which are used to detect the faults. There are numbers of automated software testing tools with different purposes but it is always a problem to select a software testing tool according to the needs. In this research, the author compares two software testing tools i.e. Apache JMeter and HP LoadRunner to determine their usability and efficiency. To compare the tools, different parameters were selected which guide the tool evaluation process. To complete the objective of the research, a scenario-based survey is conducted and two different web applications were tested. From this research, it is found that Apache JMeter got an edge over HP Loadrunner in different aspects which include installation, interface and learning.

Examining current academic and industry Enterprise Service Bus knowledge and what an up-to-date testing framework could look likeOlsson, Joakim, Liljegren, Johan January 2012 (has links)
Nowadays integration and interoperability can make or break an enterprise's business success. In the huge space that is software engi- neering a lot of ESBs have emerged but with vast di erences in imple- mentation, patterns and architectures. To create order in this disarray studies have been made, features eval- uated and performance measured. This is a good thing but it does not clear up all the confusion and adds another layer of confusion regarding the studies and tests themselves. The aim of this thesis is to make an attempt of rectifying some of the disorder by rst evaluating the current body of knowledge and to provide a humble attempt of making a transparent test framework which could be used for a more coherent ESB evaluation.
