Apache JMeter Tutorial and Basic Terminology
Before proceeding with this tutorial, let us first understand some key terms which are associated with the testing of any application.
Performance Testing
- Software performance testing is a type of non-functional testing in which the performance of the application is evaluated under expected or higher load.
- Performance testing is carried out to measure different performance attributes of the system like - response time (speed), reliability, resource usage, scalability, Stability under a variety of load conditions etc.
Why do we need Performance Testing?
- Before launching the final software product in the market, the product should be tested against the speed, scalability and stability under variety of load conditions.
- If the product goes live without doing performance testing, itmay cause issues like slow processing and poor usability which likely to gain a bad reputation and it affects the expected sales goal directly.
Types of Performance Testing
Load Testing
- Load testing is a type of performance testing that simulates a real-world load on any software, application, or website.
- It helps to determine how the system behaves under both normal and at peak conditions.
- Load testing can be performed under controlled lab conditions to compare the capabilities of different systems or to accurately measure the capabilities of a single system.
Stress Testing
- Stress testing is also a type of performance testing which helps to determine the ability of a computer, network, program or device to maintain a certain level of effectiveness under unfavorable conditions.
- Stress testing is also known as Fatigue testing.
