• 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


• 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:


• 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.

Performance testLoad Test:

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. Stress testing may have a more specific meaning in certain industries, such as fatigue testing for materials

5. Web service testing


A Web service is a method of communication between two electronic devices over the web (internet).

The W3C defines a "Web service" as "a software system designed to support interoperable machine-to-machine interaction over a network". It has an interface described in a machine-processable format (specifically Web Services Description Language, known by the acronym WSDL).
