Every professional in the Software Testing & Quality Assurance domain is undoubtedly mindful of HP’s LoadRunner.
LoadRunner is a well-known next generation performance verification & validation tool due to HP. This can be a unique tool by which we will 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 built to accurately predict the specific performance and behavior in the application, thereby increasing our confidence in the robustness of the new system before it gets actually deployed.
A newbie has been made to take out a self-learning / Training series wherein the aspirants can Learn & Master LoadRunner through Premium quality Question Answers. Having a mastery throughout these Question Answers on LoadRunner, one can feel safe within this vast topic, while facing interviews also, in every leading MNC.
Handful of such Question & Outcomes are presented below:
Q. 1: Exactly what is the purpose of using HP – LoadRunner?
In solid world scenario, it’s not at all easy to create situation involving say 1000 users by using a system simultaneously so that you can test the behavior in the system under such stressful conditions. LoadRunner can make a real situation.
LoadRunner artificially simulates thousands of users – which can be called Virtual Users. These artificial / digitally created users are simultaneously expected to work on precisely the same task, thereby loading the device in many ways it can be supposed to be loaded by real human users in actual practice.
With LoadRunner we will simulate situation with hundreds or thousands of artificial users & we will impose definite, consistent and repeatable loads about the system thereby stressing it from end-to-end. By doing this we will emulate several business processes & production conditions, that any deployed application will probably encounter.LoadRunner accurately measures, monitors, and analyzes a system’s performance and functionality.
Q. 2: What are essential capabilities we glance in a typical application performance-testing Tool?
Essential capabilities associated with an application performance testing tool are that:
1) It ought to be capable to test a system which mixes many applications and hardware platforms.
2) It ought to be capable to determine the suitability of any server for just about any given application.
3) It ought to be capable to test the server prior to the necessary client software is developed.
4) It ought to be capable to emulate a breeding ground where multiple clients interact with just one server application.
5) It ought to be capable to test an application in the load of tens, hundreds, or even thousands of potential users.Q. 3: What are drawbacks of manual load testing processes?
Load testing of any complete system can be done manually because they build a breeding ground where lots of users work simultaneously about the system. Each user was made to work with his standalone machine and each individual submits input somewhere. However resulting from complexity for these a system, following drawbacks are available
1) Manual testing methods offer only an incomplete strategy to the stress testing.
2) Manual tests are expensive & requires copious amounts 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 in the manual tests is bound.
