Performance testing is a type of testing intended to investigate quality-related characteristics of an application that may impact actual users by subjecting it to reality-based simulations. This process can involve quantitative tests, such as measuring the response time or the number of MIPS (millions of instructions per second) at which a system functions. Qualitative attributes such as reliability, scalability and interoperability may also be evaluated.

Without performance validation, there is great risk that the application will not provide the performance necessary to adequately support the business; this will result in customer dissatisfaction, lost business opportunity, and/or lost revenue.

Performance testing can serve different purposes. It can demonstrate that the system meets performance criteria. It can compare two systems to find which performs better. Or it can measure what parts of the system or workload cause the system to perform badly.

Why hire performance testers from Nonead

Our competency

Nova's performance testers have been actively engaged in this field for 2 years. Most of them have 2 years of software test experience. Our competency lies in following aspects:

• Excellent communication skills and comprehension ability
  On the one hand, Nova's performance testers can get familiar with your software or requirement rapidly and accurately; one the other hand, they do not have intercultural communication problems at all in face-to-face communication, conference calls, instant messengers or emails with clients. Moreover, all the relevant documentations will simultaneously be prepared in English.
• Rich experience in performance testing
  Most of Nova's performance testers have rich experience in performance testing. At first, they can help you to identify performance acceptance criteria correctly; then, they can do well in performance testing process; at last, via analyzing testing results, they can help you locate the bottleneck of your software and give appropriate advice for improvement.
• Good command of performance testing tool.
  Automated tools are necessary to performance testing. Nova performance testers are proficient in LoadRunner which is one of the most popular and useful performance testing tools.
• Strong testing result analysis capability
  After executing performance tests, Nova's performance testers will make a comprehensive analysis about testing results. Finally, we will locate the bottleneck of your system to help you improve it. Moreover, related performance reports will be submitted to you.

As a company, Nova backups our performance testers with:

• Effective project management
• Project Inspection Team
• Continual documentations
• Suitable development methodology
• Outstanding communication skills

Our experience

Via accomplishing several performance testing projects, our performance testers have mastered each part of performance testing procedure. Briefly described as follows:

• Identify performance requirement
  Through getting familiar with the tested software and communicating with clients, identify the response time, throughput, and resource utilization goals and constraints. In general, response time is a user concern, throughput is a business concern, and resource utilization is a system concern. Additionally, identify project success criteria that may not be captured by those goals and constraints.
• Design testing plan and schema
  Identify key scenarios, determine variability among representative users and how to simulate that variability, define test data, and establish metrics to be collected. Consolidate this information into one or more models of system usage to be implemented, executed, and analyzed.
• Use Load Generator to simulate the actual environment
  Before this, Nova LoadRunner testers may get the actual environment via communicating with client, the data is the foundation of set Load Generator.
• Analyze scenario result
  Run and monitor your tests. Validate the tests, test data, and results collection. Execute validated tests for analysis while monitoring the test and the test environment.
• Submit detail report and suggestions for improving
  The last step of LoadRunner testing procedure is analyzing and report. Analyze the results, locate the bottleneck and give report including testing results, analysis results and improving suggestion to client.
