Performance Testing
Performance Testing tests the performance of a system or an application to find how well it can handle various levels of load, stress, etc. It is majorly an exercise to realise the limits of the application.

Simulating multiple users in a synchronized manner requires the use of performance tools. There are different types of performance test tools available in the market- ranging from open source HTTP drivers to commercial types that can simulate state-of-art web technologies and proprietary ERP/CRM solutions. Some are even hosted as cloud-based solutions to simulate “outside the firewall” load, common in today’s application delivery landscape. Even enterprise class commercial performance testing tools may not offer out-of-box support for certain evolving and newer technologies. The licensing models adopted by the product vendors can be restrictive and expensive and procurement decisions should only be made after careful analysis to understand the fitness of the tools in your own environment. Testhouse consultants are vendor agnostic and certified on various performance test tools and experienced in using the advanced product features.

Performance Test Strategy

Performance testing requires collaborative effort from business experts, performance testers, application developers and infrastructure experts, alongside a requirement for expensive tooling, dedicated environments and large amounts of test data. The demands on resources and tools make performance testing an expensive exercise and needs a detailed plan to be a success. Often the performance requirements can be ambiguous and the performance test objectives unclear, leading to incomplete testing exercises later in the software development lifecycle. Without careful thought, incorrect assumptions may be made for workloads, concurrency, environment scaling, size and shape of test data etc. which may lead to results different to those experienced in live system. Business owners may develop false confidence in the system based on incorrect test results. Testhouse consultants can assist you in accurate modelling of performance test scenarios by implementing good practises through proven organisation/ project level performance test strategies. With our help, you will be able to build and test for performance earlier in the lifecycle.

Performance Test Implementation

Performance testing requires specialised skills for stakeholder management and co-ordination, requirements elicitation, workload modelling, test tool installation and configuration, performance test scripting, results analysis and correlation and performance tuning/optimization. Compatibility of the test tools with technologies, availability of skilled resources, environment and data availability, security policies and procedures etc. can present challenges to performance testing irrespective of the exercise being one off or part of a routine. Testhouse can provide the necessary additional help you may require on your time-critical projects. Should your organization be keen to embed performance testing as a standard engineering practice, we can help you irrespective of whether you are following a waterfall or agile methodology. Our consultants can function as an extension to your internal performance test team, assisting them to cover shortfalls in resources and skills.

Agile Performance Test

Performance testing in a waterfall project is normally undertaken towards the end. A large scale end-to-end performance testing project takes weeks to complete and has dependencies on the completion of functional testing and production like environments. Identified performance bottlenecks often require structural and design changes. Design changes late in the lifecycle are expensive and require additional cycles of testing. Performance testing in agile projects follow a different and layered approach using multiple tools in shorter test cycles. Performance targets can be defined for different stages of development – at code, feature and system levels. Whilst code profilers can be used to performance optimize code, feature level performance tests can be carried out within each sprint to meet “done criteria”. System level tests can be carried out on a weekly or end -of-sprint to understand the performance trends and how the addition of features affects the overall performance baseline. Our consultants can assist you to evolve your performance testing practices in agile projects.

App Performance Monitoring

E-commerce applications must be performant, consistent and available to meet revenue goals. Slow applications drive customers to your competitors whilst application unavailability affects the volume of trade. Internet load spikes are highly unpredictable and events such as discount sales and clearances can drive application demand to an extreme. Network level peering issues can lead to poor performance for users in certain geography. There is a growing trend to understand how well applications cope in real-world conditions. Performance testing in isolated test environments should be complemented with real application performance monitoring from different points on the globe. Application performance monitoring allows stakeholders to understand the amount of revenue lost through poor performance besides giving them an opportunity to intervene pro-actively in case performance degradation is identified. There are different methods and tools for application performance monitoring. Our consultants can advise how best to implement them for your maximum benefit.
