Important factors of Performance Testing

 

Following are some of the important points against performance testing:::

1. We can setup global sampling rate, error handling, debugging and frequency settings in Monitor properties.
2. In manual correlation, we can include maximum of 64 parameters per script. 
3. By default, all Vusers information is stored in Vuser Host. 
4. Granularity of the graph can be set in seconds, minutes and hours. 
5. Online monitor can send '5 updates' to the controller for data graph.
6. VuGen generates "icon and title" for representing all the actions done by virtual user.
7. By default, 3sec is defined for the sample rate and we use seconds unit of sampling rate in the online monitoring.
8. JSON, XML and BASE64 are the formats that contain valid VuGen built in DFEs

Performance Testing Case Study - Important factors

Following methods and steps involved for doing end to end performance testing of web application:

1. Understanding Physical architecture
2. To know the current status of application
3. Gather performance testing requirements
1. Protocol Selection
2. Identify scripting language 
4. Evaluate the performance testing set up
1. Network bandwidth settings
5. Start implementing transaction scripting
1. Recording scripts
2. Replay scripts
3. Correlation
4. User data  parameterisation
6. Scenario creation
1. Iteration settings
2. Ramp up / Ramp down users
7. Performance test execution
1. Mimic browsers
8. Analysis
