QATestLab believes that performance and load testing activities should be used at early stages of the software development life cycle in order to follow performance related requirements and configure the test design and the development efforts as well.
The performance errors undetected before the launch might lead to costly reworks and stressful launcing.
Our team provides clients with information about how to follow the performance requirements in terms of application, network, servers, and how to do load, stress, volume testing, etc during performance testing service.
As performance testing includes load, stress, scalability, reliability and volume testing, QATestlab determines the right tests required for the application.
For example, some load tests verify the required load level by increasing the number of virtual users in order to reach the certain performance level.
Stress testing is performed by increasing the load cycles duration and the number of hits, but in the same time by reducing the response time.
During scalability testing we exercise an application at an increasing number of concurrent users to determine when the application fails. Scalability testing purposes depend on the business need and criticality of the application under test.
Using these different test types our performance testing approach allows making the applications more reliable by identifying where, when and under what circumstances the application breaks.
