Realistic Performance Testing is one of the challenges for the overall project team. Performance Testing of any application or system has two primary objectives: Considering the above-mentioned two main goals, a performance tester designs the performance test strategy, approach and tool. All the performance testing tools follow the SEA pattern which means: SEA Pattern The way … Read more
HTTP status response code is a common and very useful term in performance testing. Any performance testing tool primarily validates HTTP Status Response Code to mark a request as pass or fail. Many times you have seen HTTP 500/404/403 as a response code while playing back the script and that leads you to debug the … Read more
Latency, Throughput, Bandwidth and Response Time; somehow these terms are very confusing. A new performance tester faces difficulty to understand these terms without examples. This article will help to get the knowledge of Network Latency, Network Bandwidth, Data Throughput and Response Time. So, let’s start now, Look at the above figure (Figure 01). The illustration … Read more
Think Time and Pacing have significant importance in Performance Testing. They are very basic terms which are specially used while designing the workload in the workload modelling phase of PTLC (Performance Test Life Cycle). They are used to control the transaction rate during a load test but have significant differences. A new performance tester is … Read more
Many performance testers do not know the importance of Standard Deviation in performance testing and hence give less attention to it. Standard Deviation is a key metric in performance test result analysis which is related to the stability of the application. The calculation of Standard Deviation is a bit complex and the probability of making … Read more
YouTube Video Link: 90th Percentile in Performance Testing ‘Percentile’ – a common but most important term, especially in performance testing. From the day first when we started analysing any performance testing report, we heard about the 90th percentile. Even our mentor gave more stress on the 90th percentile figures for response time.
