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. Q.When do you do load and performance Testing? Ans: We perform load testing once we are done with interface (GUI) testing. We use LoadRunnerвЂ™s graphs and reports to analyze the applicationвЂ™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.

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. Q.Explain the Load testing process? Version 7.2 Ans: Step 1: Planning the test. Vusers are automatically 'Stopped' when the Load Generator is overloaded. Vusers are 'Finished' in passed or failed end status. The Status of Vusers on all load generators start from 'Running', then go to 'Ready' after going through the init section of the script. So threading supports more Vusers per load generator. During run-time, threadedvusers share a common memory pool.

Only one GUI user can run from a machine unless LoadRunner Terminal Services Manager manages remote machines with Terminal Server Agent enabled and logged into a Terminal Services Client session. But WinRunner GUI Vusers emulate keystrokes, mouse clicks, and other User Interface actions on the client being tested. Load generators are controlled by VuGen scripts which issue non-GUI API calls using the same protocols as the client under test. Q.What is Virtual Users? Ans: Unlike a WinRunner workstation which emulates a single user's use of a client, LoadRunner can emulate thousands of Virtual Users. Q.What are the components of LoadRunner? Ans: The components of LoadRunner are The Virtual User Generator, Controller, and the Agent process, LoadRunner Analysis and Monitoring, LoadRunner Books Online. 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.

Q.What is Performance testing? Ans: Timing for both read and update transactions should be gathered to determine whether system functions are being performed in an acceptable timeframe. Q.What is load testing? Ans: 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.
