Very good help for all especially for the beginners. Hi friends.. Currently I am working in telecom testing non-IT , i would like to make my career in Software Testing, please can some guide me how I can proceed further. I actually appreciate the material you have on your web site it extremely has helped me out a whole lot thanks. Software Testing Class. What is Performance Testing? STC Admin October 23, Why do performance testing? Types of Performance Testing: 1 Load Testing : Load Testing is type of performance testing to check system with constantly increasing the load on the system until the time load is reaches to its threshold value.
Simple examples of load testing: Testing printer by sending large job. Editing a very large document for testing of word processor Continuously reading and writing data into hard disk. Running multiple applications simultaneously on server. This testing is to be carried out under controlled environment before launch, so that we can accurately capture the system behavior under most erratic scenarios 3 Spike testing : Spike testing is subset of Stress Testing. Problem Investigation like bottlenecks memory, disk, processor, process, cache, network, etc.
Based on the analysis prepare recommendation report. Repeat the above test for the new build received from client after fixing the bugs and implementing the recommendations 7 Analyze Results, Report, and Retest Consolidate, analyze and share test results.
Common Performance Problems: In the software testing of an application Speed is one of the important attribute. Here is the list of most commonly performance problems observed in software system: Poor response time Long Load time Bottlenecking Poor scalability Software configuration issues for the Web server, load balancers, databases etc.
Disk usage Operating System limitations Poor network configuration Memory utilization CPU utilization Insufficient hardware resources Conclusion: For the success of Software system Performance testing plays a key role software testing life cycle.
Thank you very much, this Performance testing article really help for us. Thanks for this bright explaination Reply. In the last few years, however, several pockets of testers and developers have collaborated independently to create tuning teams.
Because these teams have met with significant success, the concept of coupling performance testing with performance tuning has caught on, and now we call it performance engineering. In Software Engineering, Performance testing is necessary before marketing any software product. Costs of performance testing are usually more than made up for with improved customer satisfaction, loyalty, and retention.

A single test will not tell developers all they need to know. Successful performance testing is a collection of repeated and smaller tests:. Image credit Varun Kapaganty. In addition to repeated testing, performance testing will be more successful by following a series of performance testing best practices:.
Performance testing fallacies can lead to mistakes or failure to follow performance testing best practices. According to Sofia Palamarchuk, these beliefs can cost significant money and resources when developing software :. As mentioned in the section on performance testing best practices, anticipating and solving performance issues should be an early part of software development. Implementing solutions early will less costly than major fixes at the end of software development.
Adding processors, servers or memory simply adds to the cost without solving any problems. More efficient software will run better and avoid potential problems that can occur even when hardware is increased or upgraded. Conducting performance testing in a test environment that is similar to the production environment is a performance testing best practice for a reason.
The differences between the elements can significantly affect system performance. It may not be possible to conduct performance testing in the exact production environment, but try to match:. Be careful about extrapolating results. Also, it works in the opposite direction. Do not infer minimum performance and requirements based upon load testing.
All assumptions should be verified through performance testing. Not every performance problem can be detected in one performance testing scenario. But resources do limit the amount of testing that can happen.
In the middle are a series of performance tests that target the riskiest situations and have the greatest impact on performance. Also, problems can arise outside of well-planned and well-designed performance testing. Monitoring the production environment also can detect performance issues.
While it is important to isolate functions for performance testing, the individual component test results do not add up to a system-wide assessment.
But it may not be feasible to test all the functionalities of a system. A complete-as-possible performance test must be designed using the resources available. But be aware of what has not been tested. If a given set of users does experience complications or performance issues, do not consider that a performance test for all users.
