Performance Testing using LoadRunner 12.50

Discover why a performance tester must understand application architecture to identify bottlenecks, using monitoring and in-depth analysis of the architecture.

Understand how file, print, database, and application servers process only their respective requests, and how database and app servers use queries and deploy code to power apps like Gmail.

Learn to identify bottlenecks in a web app architecture using LoadRunner, timing across web server, app server, and database, and profiling tools like Dynatrace.

Identify LoadRunner 12.50 hardware and software requirements, including Windows 10 compatibility, 8 gb RAM, dual-core 2.2 GHz, 50 gb disk, and verify installation of analysis, controller, and virtual user generator.

Master performance testing concepts in LoadRunner: speed, stability, and scalability, testing current and future loads, and validating a production-like environment with virtual users to meet non-functional requirements.

Define key performance testing terms, explain think time versus response time, distinguish transaction response time, and introduce throughput as transactions per second for LoadRunner projects.

Differentiate performance testing from performance engineering by identifying bottlenecks and eliminating them. As a performance engineer, fine-tune web servers, app servers, load balancers, databases, and networks to minimize response times.

Gather nonfunctional requirements for performance testing by collecting infrastructure details for production and testing environments, then identify performance critical transactions by frequency, business impact, and resource intensity.

Learn to use pacing in workload modeling to meet twelve login transactions per hour with two concurrent users by deploying multiple virtual users and applying a pacing formula.

Explore the LoadRunner 12.50 components: analysis, controller, and virtual user generator, plus the load generator, and learn how they fit the performance testing lifecycle from design to analysis.

Explore how load generators, the controller, and analysis are installed on separate machines in a real-time performance testing setup, with a single controller shared by multiple testers.

Explore calculating LG capacity and virtual users in LoadRunner 12.50 by evaluating memory footprint, RAM, license limits, and group configurations managed by the controller.

Learn to create a LoadRunner script by understanding the application and test, recording, enhancing, and playback, using the web tools sample app to practice; most work happens during recording.

Create and manage web http html scripts with protocol advisor in VuGen, select the correct protocol, and organize scripts into solutions with default actions like user_init and vuser_init.

See how VUGen records events during log in and log off, uses comments to tag code blocks, and organizes scripts into launch and log off sections for performance testing.

Set the protocol in VuGen before recording to ensure network-level capture. Use the technical design document and protocol advisor to identify and choose the best protocol.

VuGen run-time settings determine the execution flow and iterations, overriding the script order to manage login, booking tickets, and logout with think time controls.

Use VuGen to insert start and end transactions to capture login and launch page timings, manage think time during debugging, and follow case-sensitive naming standards.

Explore html-based versus url-based scripts in LoadRunner 12.50, where html packs launch page resources into one request, and url-based creates multiple web requests.

Understand how load testing uses checkpoints to validate server responses, including text and image checkpoints, and learn how to select unique text to avoid false passes.

Learn to add text checkpoints in LoadRunner 12.50 using the bridge file by selecting text in the response body, and understand troubleshooting with recording, replay, and snapshot views.

Learn to implement and validate text checkpoints in LoadRunner 12.50, including case-insensitive matching, selecting text via snapshot view, and using the web bridge to verify responses within transactions.

Learn how to declare and initialize strings in C within LoadRunner, using characters, pointers, and arrays, and handle placeholders like %c and memory violations.

Compare two integers, floats, and strings in C using conditional statements, and learn why string comparisons require a dedicated C function for equality checks.

Discover how a lab parameter can hold integers, strings, or floats, with no prior declaration, and learn to copy values between data types using lr_save_int and lr_save_string.

Explore conversions in performance testing with LoadRunner, converting parameters to strings then integers to enable proper comparisons. The lecture covers buffers, watches, error handling, and step-by-step versus continuous execution.

Learn how to parameterize real time scripts in loadrunner, including usernames, passwords, and other form fields for web and banking applications, by creating parameters, supplying values, and replacing hardcoded fields.

Learn parameterization in LoadRunner by creating username and password parameters, pairing them in a single file, and debugging with extended logs and parameter substitution.

Explore parameterization in load testing by deriving username and password from a file and selecting values sequentially or randomly.

Master parameterization techniques in load testing by designing and validating test data sequences, ensuring uniqueness, and using controllers, blocks, and selectors to drive realistic test scenarios.
