Importance of LoadRunner

The internet and the engagement of the users are radically increasing which demands the load test for the applications. Websites where the load is ironically high need to be tested and examples for the high user base applications are like Facebook, linked in, and any banking website. Join the LoadRunnerTraining in Chennai to get comprehensive knowledge of the testing tools. As the load is more and constantly increasing it has to be tested with performance testing tools. The load runner was invented in 1999 and it was later acquired by HPE in 2006. In the year 2016, the ownership of the load runner was taken over by microfocus. Load runner supports many protocols and it is the best tool for performance testing. The market share of the load runner tool in the software testing market is 85 percent. Join the LoadRunner Training in Tambaram and equip yourself for the interviews.

The rich applications from the internet are supported by the load runner tool. Web 2.0 applications like HTTP, HTML, Ajax, flex, and silver light are the applications where the load runner is used. Load runners can be connected or integrated with the other tools like the QTP or ALM to complete the end to end testing process. The load runner creates the virtual users and these virtual users create the request and response of any transaction. In the case of Web 2.0 websites the end customers are valued more and if it takes time to load the website then ultimately the popularity of the website goes down. Being a static web site it is essential to interact with the customers or users to provide the information or service they require.

Architecture of LoadRunner

The architecture of the Load runner is the virtual users create real transactions with more numbers to check the load of the website. The controller takes the central place in the testing and it manages the load test. The monitors send the performance information to the controller. The results of the transactions are stored in the database for the lateral view of the customers. Users, monitors, and the controller are the three main components to perform performance testing. Join the LoadRunner Course in Chennai to know about the latest standards in the industry for automation.

The internal architecture of the load runner is application servers which are under stress, the driver process mdrv.exe and the r3vuser.exe perform three actions. The three actions are C language preprocessor, CCI create a file with the ci file, the driver is used for the execution of the protocol technology, VUsers run the same script on different load generators, load generators and client machines are connected, the agents have an execution log, for each VUser a sequential file will be created, during execution the user file is displayed, the test session scenarios are tested by the controller machine, each agent launch the RCL on load generator machine, each agent connects the scenario and the Vuser groups.

LoadRunner Training in Velachery promotes the students and transforms them as professionals in the automation industry.

Agents check the scenario definition files and connect the scenario to the host in the machines. Only one instance will run using the LoadRunner. So, the controller will use the windows OS folder to invoke the parameter values. The results from the execution are saved in the results folder. If the settings with creating the default results directory for each scenario are set then the name of the results are saved with the name after the scenario runs. Remote performance monitoring (RPM) for the load runner monitoring will be installed in the windows 2000 server. After installing RPM it becomes easy to see the results in the web browser. Join the LoadRunner Training in Adyar and know about the different measures required to use the load runner tool.

Components of LoadRunner

The user generator, controller, injector, and analysis are the four components of the load runner. Load runners can be rivaled by multiple users and these threaded users share a common memory pool. For the web servers like Apache, IIS, and Netscape no license is needed whereas for the SOAP and XML separate license is needed to monitor the protocols. The Vugen uses the non-GUI API with the same protocols and the GUI VUsers have keystrokes, mouse clicks, and the user interfaces for the multiple types of tests. The GUI user test from the same machine and the terminal server agent is enabled. The status of the Vusers is running, ready, finished, and pass or fail. If the load generator is overloaded then the user is stopped. Join the LoadRunner Training in Tambaram to learn from the industry experts about the automation and the challenges in the job of an automation engineer.

VuGen

VuGen is a coding editor with a recording option. It records the client-server in form and replicates the system under load. The different pages of a website are recorded to create a virtual user. The home page of the website, the main page of the product, the payment page of the product, and my account page are the different pages of the website where the load is recorded in the form of a user script. After recording the VUser script the next step goes to the controller.

Controller

The controller is used to simulate the load and manage the load. The information like the number of users towards the number of business process or VUser group are mentioned here, the behavior of the users like simultaneous nature, concurrent nature, ramp down and ramp up, nature of the scenario in the load like the real-time scenario or the goal-oriented scenario, the number of injectors against each VUser, the results to be collated periodically, IP spoofing, error reporting, and the transaction reporting are some of the functions of the controller in the Load runner. LoadRunner Training in OMR flourishes the future of the students and helps them to get a job.

How to handle 3500 Users

To handle such scenarios the ratio can be like initiate 5 V Users for every 2 seconds and till a load of 3500 V users, iterate for 30 minutes, cancel the iteration for 25 V Users, then again restart the process for 20 Vusers, add 2 users for every second which is the time for checking the three pages, Machine-A is used for generating 2500 VUsers and machine B is used for generating 2500 V Users.

Injectors

Each V Users need hardware resources and memory. Keeping the user and the controller will not show the right results. To overcome this problem the V Users are transferred to a wide range of various machines. These machines are called load generators or load injectors.

To get better results the controller is placed in a different machine and the load is simulated from other machines. The protocol from the VUser scripts and machine specifications decide about the number of load injectors can be used for the simulation. LoadRunner Training in Porur helps the students to gain knowledge from scratch and clear the interviews in the automation industry.

For HTTP script the V Users will require 2 to 4 MB per VUser for simulation, the requirement for the machine will be 4 and the memory will be 4 GB. This requirement is needed for 10,000 V Users.

Analysis

After executing the scenarios the analysis regarding the performance is initiated. The results are in raw forms like the version of the load runner and the configurations of the load runner. The analysis is the component in the load runner which runs the database in Microsoft access with all the errors and exceptions. The analysis part in the load runner takes care of the analysis with the graphical representation of the data derived.

The errors and failures are well understood by analyzing the graph. The reason behind the errors is shown and the optimizations are done in the form of SUL, server, J Boss, oracle, and infrastructure. If the web server is 1GB capacity and the capacity of the traffic is higher than the server load then the role of the performance engineer starts from here. The application behavior is analyzed to check the traffic load and the server load. Accordingly, the required changes are made to manage the traffic and the server load on a static website. LoadRunner Training in T.Nagar is designed to make the automation career an interesting one. The real-time projects make the students take up the challenges in the industry and reach high positions in the job.

Summary of performance testing

The process of the performance testing can be divided into five types and they are planning the test, creating the virtual user, creating the scenario as per the business requirement, executing the scenario with the user and the controller, and finally analyzing the results to make changes in the application or server. Let me see all these five steps in detail for the knowledge of the practical challenges in the process.

Planning

The different types of testing are performance testing, system integration testing {SIT}, User acceptance testing {UAT}, and web application testing. The planning part is different for all these testing. The different roles of the performance testing team are project manager, business analyst, performance test expert, system architect, system administrator, web developer, and SME. The project manager takes care of the whole process from time to time. The business analyst provides the functionality of the website in different scenarios. The performance test expert creates the scenarios and executes the tests. The system architect handles the network problems and provides the blueprint of the SUL. Web developers maintain the website and monitor the website to fix bugs. A system administrator takes care of the server throughout the test process. LoadRunner Training in Anna Nagar helps the students to land in their dream and join the big community of testers to bring development in the testing industry.

The objective of the test

The business objective or analyzing the business process is a crucial step in the load test. For example, to analyze the functions on the website or system first prepare a chart of the time table for the website or system. From time to time know the users for the application, the maximum number of users, and a total number of users to the application.

Management procedures

The business processes are highly complicated to understand. The process and hierarchy of management show the usage of the application. Analyze every scenario with the management procedures because the real-time process and the management process sometimes differ with some small differentiation.

Hardware requirements

Check the hardware requirements of the system because the hardware change will have a great impact on performance testing. Processors, RAM, Web or APP server, Database server, network bandwidth for the utilization, in case of clustering internal and external NIC, load balancer, the data movement from the client and server which is called as data flux, Data flux is calculated. These details are very important before conducting the load test. This aids in the successful completion of the load test. Join the Best LoadRunner Training Institute in Chennai, FITA, and realize the value of choosing the best training when pursuing the job.

Change the number of users

Monitor the process from creating the VUGen scripts, creating the load scenario, and execution with appropriate measures. The number of Users is increased and decreased when testing the load in the server. This gives an idea of the stress and abnormal behavior of the application. The results are derived and then analyzed.

Graphical representation

Time to the first buffer, average transaction response time, transaction response time, hits per second, error statistics, windows resources, and transaction summary are some of the graphical representations of the test result for the analysis by the HP tool.
