Mastering HP LoadRunner Through Question Answer Training Series
Every professional from the Software Testing & Quality Assurance domain is undoubtedly aware of HP's LoadRunner.
LoadRunner is a well-known next-gen performance verification & validation tool through HP. That is a unique tool where we are able to simulate situation with hundreds or thousands of artificial users & can impose definite, consistent and repeatable loads about the system thereby stressing it from end-to-end.
LoadRunner is made to accurately predict the specific performance and behavior of the application, thereby increasing our confidence inside reliability of the brand new system before it gets actually deployed.
An initial has been made to create out a self-learning / Training series wherein the aspirants can Learn & Master LoadRunner through Top quality Question Answers. Which has a mastery during these Question Answers on LoadRunner, you can have confidence on this vast topic, while facing interviews too, in different leading MNC.
A couple of such Question & Email address details are presented below:
Q. 1: What's the aim of using HP - LoadRunner?
In real world scenario, it isn't possible to create situation involving say one thousand users utilizing a system simultaneously in an attempt to test the behaviour in the system under such stressful conditions. LoadRunner can establish this sort of situation.
LoadRunner artificially simulates thousands of users - that are called Virtual Users. These artificial / digitally created users are simultaneously instructed to operate on precisely the same task, thereby loading the machine in a way it really is supposed to be loaded by real human users in actual practice.
With LoadRunner we could simulate situation with hundreds or a large number of artificial users & we will impose definite, consistent and repeatable loads within the system thereby stressing it from end-to-end. This way we could emulate several business processes & production conditions, that any deployed application is likely to encounter.
LoadRunner accurately measures, monitors, and analyzes a system's performance and functionality.
Q. 2: What are the essential capabilities we look in a typical application performance-testing Tool?
Essential capabilities connected with an application performance testing tool are that:
1) It must be able to test something which mixes many programs and hardware platforms.
2) It has to be able to determine the suitability of a server for any given application.
3) It ought to be capable to test the server prior to the necessary client software is developed.
4) It has to be in a position to emulate a setting where multiple clients interact with one particular server application.
5) It ought to be capable to test a questionnaire underneath the load of tens, hundreds, or maybe a huge number of potential users.
Q. 3: What are the drawbacks of manual load testing processes?
Load testing of your complete system may be accomplished manually because they build a place where lots of users work simultaneously for the system. Each user was created to work towards his standalone machine and each and every individual submits input to the system. However due to complexity of such something, following drawbacks are there
1) Manual testing methods offer only a partial treatment for the strain testing.
2) Manual testing is expensive & requires a lot of manpower & equipment.
3) Manual tests are complicated, especially while coordinating and synchronizing multiple testers.
4) Manual testing involves a very high amount of organization, especially to record and analyze results meaningfully.
5)The repeatability of the manual tests has limitations.
