What Component of LoadRunner would you use to play Back the script in multi user mode?.It enables you to develop Vuser scripts for a variety of application types and communication protocols. #INTERVIEW QUESTIONS ON NEOLOAD FOR PERFORMANCE TESTING GENERATOR#The Virtual User Generator (VuGen) component is used to record a script. What Component of LoadRunner would you use to record a Script?.The components of LoadRunner are The Virtual User Generator, Controller, and the Agent process, LoadRunner Analysis and Monitoring, LoadRunner Books Online. What are the components of LoadRunner?.This is when we set do load and performance testing. This gives rise to issues such as what is the response time of the system, does it crash, will it go with different software applications and platforms, can it hold so many hundreds and thousands of users, etc. For example, a typical application-testing scenario might depict 1000 users logging in simultaneously to a system. Whereas single user testing primarily on functionality and user interface of a system component, application testing focuses on performance and reliability of an entire system. Modern system architectures are large and complex. We perform load testing once we are done with interface (GUI) testing. When do you do load and performance Testing?.We use LoadRunner’s graphs and reports to analyze the application’s performance. During scenario execution, LoadRunner records the performance of the application under different loads. We monitor scenario execution using the LoadRunner online runtime, transaction, system resource, Web resource, Web server resource, Web application server resource, database server resource, network delay, streaming media resource, firewall server resource, ERP server resource, and Java performance monitors. We can run the entire scenario, Vuser groups, or individual Vusers. Before the testing, we set the scenario configuration and scheduling. We emulate load on the server by instructing multiple Vusers to perform tasks simultaneously. LoadRunner automatically builds a scenario for us. For web tests, we may create a goal-oriented scenario where we define the goal that our test has to achieve. #INTERVIEW QUESTIONS ON NEOLOAD FOR PERFORMANCE TESTING MANUAL#In manual scenarios, we define the number of Vusers, the load generator machines, and percentage of Vusers to be assigned to each script. We can create manual scenarios as well as goal-oriented scenarios. We create scenarios using LoadRunner Controller. It includes a list of machines, scripts, and Vusers that run during the scenario. A scenario describes the events that occur during a testing session. Here, we create Vuser scripts that contain tasks performed by each Vuser, tasks performed by Vusers as a whole, and tasks measured as transactions. Here, we develop a clearly defined test plan to ensure the test scenarios we develop will accomplish load-testing objectives. This should be done standalone and then in a multi user environment to determine the effect of multiple transactions on the timing of a single transaction. #INTERVIEW QUESTIONS ON NEOLOAD FOR PERFORMANCE TESTING UPDATE#Timing for both read and update transactions should be gathered to determine whether system functions are being performed in an acceptable timeframe. Load testing is to test that if the application works fine with the loads that result from large number of simultaneous users, transactions and to determine weather it can handle peak usage periods. ![]() WinRunner LoadRunner Test Director Silk Test Test Partner ![]()
