An Introduction To Performance Testing

• Performance testing is the process of testing the
  software application for the non-functional
  aspects like response time, speed, reliability,
  and scalability under different workloads. The
  main purpose of performance testing is to
  identify the performance bottlenecks of software
  applications and eliminate them for better usage.
  The performance testing is to test the speed,
  scalability, and stability. The major objective
  of performance testing is to provide the
  information to the stakeholders about the
  application's reliability, scalability, response
  time, throughput time, and other non-functional
  aspects.
• If the performance testing is not performed then
  there will always be a possibility of having
  issues such as slow response time, weak
  throughput, weak connection time, etc.
  Performance testing is important for software
  applications with long duration of usage and with
  large deviations in workloads.

• Types of Performance Testing
• Load Testing - It is used to test the software
  application performance under large user loads.
  It ensures that software applications will work
  when thousands and millions of users are working
  on software applications simultaneously.
• Stress Testing - Stress testing is used to
  identify the application usage when an extreme
  workload is applied to the software application.
  The objective of software applications is to
  identify the breaking point of the application.
• Endurance Testing - This is used to test the
  software application and how it will perform
  under a long duration of usage.
• Spike Testing - Spike testing is used to test
  the application with sudden increases and
  decreases in user loads.
• Volume Testing - Under Volume Testing large no.
  of data is populated in the database and the
  overall system functionality is monitored. The
  objective of volume testing is to determine how
  the software handles large volumes of data.
• Scalability Testing - It is used to test the
  scalability of software applications i.e. to
  determine whether the application can be upgraded
  in the future for usage by more no. of users.
