By Admin Oct 01, 2020

SmartQE, a performance testing and engineering opensource framework addresses the performance testing, tuning, post production monitoring, design & architecture evaluation of Web and API technology stack, using leading opensource performance testing and monitoring tools.

Challenges
  • Do you know frequent downtime of application/product and performance issues damage the reputation of your brand?
  • Do you notice Application/product not cope with expected user load at normal and peak loads with desired response times?
  • Do you have to handle extended loads or sudden increases in load during normal business hours?
  • Are you sure about the performance of application is consistent and reliable on various browsers and operating systems?
  • Is your performance testing strategy revealing application behaviour at various conditions?
  • Are you sure about Reliability and consistence of application/system support future business growth?
  • Do you spend days’ time to setup performance test lab?
  • Organizations are challenges to achieving and maintaining their business’s mission critical applications at peak performance and scalability levels with optimal hardware and software resources.
  • Do you know the direct infrastructure update, migration will have risks and impact on overall output and fall behind the business requirements and delays in development?
SmartQE’s Key Features :

Agile Performance Testing - Performance test requirements are identified against the key functionality of an evolving application. This will add scope during subsequent sprints so that, over time, coverage will expand and any performance problems will identify early in the life cycle.

Tests are run automatically with continuous integration. Design and deliver performance test suites on the SmartQE and opensource tools and integrating with Jenkins and Docker container platform.

By running these tests regularly, confidence in application performance can be maintained throughout the development process. This reduces the application rework further down the line, when inevitable performance problems are discovered.

Agile Performance Engineering - Design and implement integrated Performance Testing into your development process that allowing development teams better, earlier visibility of potential performance problems identifying and fixing issues early in the life cycle.

Supported Non-functional testing types
  • Single User - It is conducted for assessing performance of the application when only single user is accessing the system
  • Light Load - It is conducted for validating the performance characteristics of the system when subjected to workload / load volume much lesser than what is anticipated during the production load.
  • Load - It is conducted for validating the performance characteristics of the system when subjected to workload / load volume what is anticipated during
  • Stress/Volume - It is conducted to make sure that the application can sustain more load than anticipated on production load
  • Recovery - It is conducted to make sure that the application is able to heal itself when load is decreased from failure point to stress point & then to normal load
  • Spike - It is conducted to find out the stability of the system when it is loaded in burst of very small time and releasing the load quickly to normal load.
  • Soak/Endurance/Reliability/Availability/Stability - It is conducted to find if system is capable of handling expected load without any deterioration of response time / throughput when run for a longer time.
  • Resilience - It is conducted to make sure that the system is capable of coming back to initial state (from stressful state to load level state) when it is stressed for short duration.
  • Failure - It is conducted to find out the capability of the application in terms of load. The load (concurrent users or volume) is increased until the application crashes.
  • Network Testing - Network performance test primarily tests the uplink and downlink speed of a network. It defines how quick and responsive a network is to user/data communication under different bandwidth.
