How do you identify which protocol to use for any application?
Previously Performance tester had to depend much on the development team to know about the protocol that application is using to interact with the server. Sometimes, it also used to be speculative.
However, LoadRunner provides a great help in form of Protocol Advisor from version 9.5 onwards. Protocol advisor detects the protocols that application uses and suggest us the possible protocols in which script can be created to simulate the real user.
What are the different components of LoadRunner?
The major components of LoadRunner are:
Explain what is the throughput for Performance Testing?
In performance testing, throughput is referred to the amount of data transported to the server in responds to the client request at a given period of time. It is calculated in terms of requests per second, calls per day, reports per year, hits per second, etc. Performance of application depends on throughput value, higher the value of throughput -higher the performance of the application.
Mention what are the phases of automated performance testing?
Phases of automated performance testing includes
What is a Modular approach to scripting?
In Modular approach, a function is created for each request (e.g. login, logout, save, delete, etc.) and these functions are called wherever required. This approach gives more freedom to reuse the request and saves time. With this approach, it is recommended to work with web custom request.
