• Performance test (PT) is an automated testing method in order to determine the speed, load and ability to trust level of the software in the environment many users
• Include Load test và Stress test
Performance test
Seminar Software Testing – Group D 60
• Load testing is the process of subjecting a computer, peripheral, server, network or application to a work level approaching the limits of its specifications.
• Load testing can be done under controlled lab conditions to compare the capabilities of different systems or to accurately measure the capabilities of a single system.
• Load testing is a part of a more general process known as performance testing
Performance testLoad Test:
Seminar Software Testing – Group D 61
• Load testing can obtain a qualitative idea of how well a system functions in the "real world."
• Pinpoint bottlenecks, bugs and component limitations -> find solution to solve it.

Stress Test:
• Stress testing is a form of testing that is used to determine the stability of a given system or entity. It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results.
