Performance Testing

Performance Testing Services

In face of the increasing focus on balancing loads and determining performance at peak concurrency times around well-written code, performance testing forms the crux of software development process. It also helps evaluate response time, resource utilization, and develop the desired framework for preparing release schedules after successful completion of performance testing process.

Performance Testing: Benchmarks

It is essential to set benchmarks and standard cut-offs before initiating a benchmark process. It can fairly assess which parts of the system require comprehensive load testing, as against which systems can be test-compared with other similar or simulated systems. The goals in terms of performance might vary based on the business goals.

1. Efficiency and Throughput:

Certain systems restrict I/O information exchange beyond a certain limit of logged users. As such, performance goal in this scenario is set on a maximum throughput rate.

2. Response Time:

It determines whether the desired turnaround time for server response is implemented successfully in real-time – for instance, HTTP request by a browser sent to the web server.

3. Recovery:

In certain real-time applications, it is crucial to test if system components return to normal state in case of exceptional event such as system breakdown or a failure at the instance of execution.

Performance Testing Specifications: System Scope

Ahead of initiating and going about the process, performance testing experts would find answers to critical queries – some of which include:

  • What is application-level workload mix (check-in/search/check-out) or distribution of interfaces/sub-systems?
  • How is the target server/network configuration placed against the expected software systems’ performance?
  • Most importantly, what is the detailed test scope for accommodating the influx of concurrent users at peak?

Performance Testing: Replicating Workloads

One of the so-called mysterious factors is about workloads being unpredictable. Performance testing experts advocate setting the closest range of fluctuating workload magnitudes against the test parameters. It helps very closely recreate ‘occurrences’ from the production environment into the testing environment – thereby delivering genuine findings.

Performance Testing: Steps

  • Elicit requirements for entire scope of performance testing activities from users and business analysts
  • Develop scenarios and test-cases with specification of workloads, environments and the tools utilized
  • Decide on resources and timelines as well as the mode of validation and deliverables to the stakeholders
  • Install injectors and controllers along with configuring the overall performance testing environment
  • Carry a dry run of the tests well ahead of the load testing based on pre-defined use-case scenarios
  • Execute the tests based on the finalized plan and record errors that crop in without being accounted for
  • Analyze results and critical paths to resolve issues based on timeline to sign off performance testing process

Engro Performance Testing at Ease

For a successful and ideal performance testing process, our experts call for genuine documentation, which offers space to clients’ requirements – that usually differ from one stakeholder to another. A detailed documentation – governed by Best Practices - would define scope, functions, modalities, and forms of testing along with expected range of results and validate each of those effectively. We thereby help organizations and thought leaders continue pursuing innovation with validated and tested performance benchmarks.
