What is
performance
testing ?
• Performance testing is basically comes under non-functional testing
• Performance testing is a testing measure that evaluates the speed,
responsiveness and stability of a computer, network, software program or
device under a workload
• The goal of the performance testing is to find bugs but to estimate
performance bottleneck.
• The focus of performance testing is
▪ Speed - Defined as speed of response for request
▪ Scalability - maximum user access to the system
▪ Stability - application stable under vary loads

Load Testing
❖ Load testing is a type of Performance Testing that determines the
performance of a system, software product, or software application
under real-life-based load conditions.
❖ Load testing determines the behavior of the application when
multiple users use it at the same time.
❖ The load testing is carried out for normal and extreme load
conditions.
❖ The goal of load testing is to identify bottlenecks and determine the
maximum number of users or transactions the system can handle.
7
Stress Testing
❖ Stress testing is particularly important for critical software but is
used for all types of software.
❖ Stress testing is defined as a type of software testing that verifies
the stability and reliability of the system.
❖ This test particularly determines the system on its robustness and
error handling under extremely heavy load conditions
8
Endurance
Testing
❖ Endurance Testing is performed to observe whether an application
can resist the processing load it is expected to have to endure for a
long period.
❖ During endurance testing, memory consumption is considered to
determine potential failures.
❖ Performance quality is also calculated during Endurance Testing.
9
Spike Testing
❖ S pike Testing is a type of software performance testing that is done by
suddenly increasing or decreasing the load on the system or software
application
❖ The load is generated by a huge number of users and the behavior of
the system is observed.
❖ The goal of spike testing is to determine whether the system will fail or
survive in case of dramatic changes in load.
10
Volume Testing
❖ Volume Testing is a type of software testing which is carried
out to test a software application with a certain amount of data.
❖ The amount used in volume testing could be a database size or
it could also be the size of an interface file that is the subject of
volume testing.
❖ While testing the application with a specific database size,
database is extended to that size and after that the
performance of the application is tested
11
Common
Performance
problems
• Long Loading Time .
• Poor Response time.
• Poor Scalability
• Bottlenecking
• CPU utilization
• Memory utilization
• Network utilization
• OS limitations.
• Disk usage.
12
Performance
Testing Process.
• Identify test environment
• Plan and design tests
• Identify performance acceptance
criteria
• Configure test environment
• Implement test design
• Execute tests
• Analyze and report
13
Performance testing Metrices
➢ Processor usage : An amount of time processor spends executing non-ideal threads.
➢ Memory usage : Amount of physical memory available to process on a computer.
➢ Disk time : Amount of time disk is busy to read or write request.
➢ Bandwidth : Show the bits per second used by a network interface.
➢ Committed memory : amount of virtual memory used .
➢ Throughput : Rate of a computer / network receives requests per second.
➢ Hits per second : The no. of hits on a web server during each second of a load testing
