Performance Testing in Software Engineering
- Performance testing is also known as “Perf Testing”.
- performance testing is a type of software testing that evaluates that how system or application works/performs under given situation such as responsiveness, scalability and stability.
- The main aim of this testing is not to remove bugs in the application.
- This testing is mainly performed to ensure that system meets the expected requirements or not.
- Performance Testing determines :
- speed determines whether the system response quickly. Stability determines the stable form of an application under loads. Scalability ascertains that how much load an application can handle. And Reliability determines the reliability of an software application.
Performance Testing Tools :
- HP LoadRunner
- Web Load
- Apache JMeter
- Rational Performance Tester (RPT)
Types of Performance Testing :
- Load Testing
- Stress Testing
- Spike Testing
Workflow of Performance Testing :
- Collect information and analyze the product
- Design test plan
- Setup the environment
- Implement test design
- Run tests
- Result Analysis
- Generate report
Advantages of Performance Testing :
- This testing increases your optimization and capacity planning efforts.
- It ensures that system met the expected requirements or not.
- It reduces the chances of system failure.
- This is an cost effective technique.
Disadvantages of Performance Testing :
- This testing can be time-consuming.
- It is difficult to design and construct.
- It is difficult to resolve the performance bottlenecks after development.
- Maintenance of test data can be costly.
