What is Performance Testing Difference Between Performance Testing, Load Testing and Stress Testing Software Testing Help. Hi Readers In the testing world, many times we come across the terms like performance testing, load testing, and stress testing. These three terms are often misunderstood and interpreted as same concepts. However, there is a significant difference between these three testing types and it is important for a tester to understand the same. In this article, we will discuss each of these 3 testing types to understand the difference between them. Q. What is the difference between Performance Testing, Load Testing, and Stress Testing1 Performance Testing Click on below link to know more about PT What is performance testing Performance testing is the testing which is performed to ascertain how the components of a system are performing under a particular given situation. Resource usage, scalability, and reliability of the product are also validated under this testing. This testing is the subset of performance engineering, which is focused on addressing performance issues in the design and architecture of software product. The above image tells us clearly that performance testing is the superset for both load stress testing.

PDM software or PLM software whats the difference Product lifecycle management PLM is often defined as an evolutionary improvement of product data management. Other types of testing included in performance testing are spike testing, volume testing, endurance testing and scalability testing. So, performance testing is basically a very wide term. Performance Testing Goal The primary goal of performance testing includes establishing the benchmark behaviour of the system. There are a number of industry defined benchmarks which should be met during performance testing. Performance testing does not aim to find defects in the application. It also does not pass or fail the test. Rather, it addresses the critical task of setting the benchmark and standard for the application. Performance testing should be done very accurately. Close monitoring of the applicationsystem performance is the primary characteristic of performance testing. The benchmark and standard of the application should be set in terms of attributes like speed, response time, throughput, resource usage, and stability. All these attributes are tested in a performance test. Example For instance, you can test the application network performance through Connection Speed vs. Latency chart. Latency is the time difference between the data to reach from source to destination. A 7. 0kb page would take not more than 1. DSL latency1. 00 milliseconds. And, a 1. 5mbps T1 connection latency5. Another example would be of Request response model. We can set a benchmark that the time difference between the generation of request and acknowledgement of response should be in the range of x ms milliseconds and y ms, where x and y are standard digits. A successful performance test should project most of the performance issues, which could be related to database, network, software, hardware, etc. Load Testing Load testing is meant to test the system through constantly and steadily increasing the load on the system until it reaches the threshold limit. It is a subset of performance testing. Load testing can be easily done by employing any of the suitable automation tools available in the market. WAPT and Load. Runner are two such famous tools that aid in load testing. Load testing is also famous by the names like volume testing and endurance testing. However, volume testing mainly focuses on databases. And endurance testing tests the system by keeping it under a significant load for a sustained time period. The sole purpose of load testing is to assign the system the largest job it can possibly handle to test the endurance of system and monitor the results. An interesting fact here is that sometimes the system is fed with the empty task to determine the behaviour of the system in the zero load situationThe attributes which are monitored in a load test are peak performance, server throughput, response time under various load levels below the threshold of break, adequacy of HW environment, how many user applications can handle without affecting the performance. Load Testing Goal The goals of load testing include Exposing the defects in application related to buffer overflow, memory leaks and mismanagement of memory. The issues that would eventually come out as the result of load testing may include load balancing problems, bandwidth issues, the capacity of the existing system, etc. To determines the upper limit of all the components of application like a database, hardware, network, etc. To set the SLAs for the application. Example For example, to check the email functionality of an application, it could be flooded with 1. Now, 1. 00. 0 users can fire the email transactions read, send, delete, forward, reply in many different ways. If we take one transaction per user per hour, then it would be 1. By simulating 1. 0 transactionsuser, we could load test the email server by occupying it with 1. Another example of load test is shown in the image below The above image depicts a load test done in the tool called JMeter. This test is done to identify that how many users a system can handle. In this test, 1. 00 users are added after every 3. Each step takes 3. JMeter waits for 3. Once, the load reaches 1. Stress testing. Under stress testing, various activities to overload the existing resources with excess jobs are carried out in an attempt to break the system down. Negative testing, which includes removal of the components from the system is also done as a part of stress testing. Also known as fatigue testing, this testing should capture the stability of the application by testing it beyond its bandwidth capacity. So, basically, stress testing evaluates the behaviour of the application beyond peak load and normal conditions. The purpose of stress testing is to ascertain the failure of the system and to monitor how the system recovers back gracefully. The challenge here is to set up a controlled environment before launching the test so that you can precisely capture the behaviour of system repeatedly under the most unpredictable scenarios. The issues that would eventually come out as the result of stress testing may include synchronization issues, memory leaks, race conditions, etc. If the stress test is checking that how the system behaves in the situation of sudden ramp up in the number of users, it is called a spike test.
