OpenText Professional Performance Engineering

LoadRunner is the industry-standard software solution for application performance and load testing. LoadRunner emulates hundreds or thousands of concurrent virtual users, with minimal hardware, to apply accurate workloads to any application. As it drives load against the system, LoadRunner captures end-user response times for business processes and transactions to determine whether the application can meet the required service-level agreements. Nonintrusive, real-time performance monitors captures real-time performance data from every component of application infrastructure. After the test completes, the LoadRunner analysis engine provides a single view of end-user response time and infrastructure-level performance to identify the most likely causes of performance issues.

Tricentis Neoload

"Tricentis NeoLoad is a performance testing solution designed to help engineering teams validate the performance, scalability, and reliability of web applications, APIs, and microservices under realistic load conditions. It is a type of load and performance testing platform that helps QA engineers, developers, and performance specialists simulate large numbers of virtual users and measure application behavior under stress, peak load, and endurance scenarios. NeoLoad combines protocol-based and browser-based test generation to support a wide range of application architectures, from legacy monolithic systems to modern microservices and cloud-native applications. Teams can design tests using a codeless interface, as-code (YAML), or scripted approaches, making the platform accessible to both technical and non-technical testers. The platform integrates with CI/CD pipelines to enable continuous performance testing as part of the software delivery workflow, and can convert existing Tricentis Tosca and Selenium functional test scripts into performance tests to accelerate test design and maintenance. Key capabilities include: - AI-powered agentic performance testing with a built-in AI chat interface and Model Context Protocol (MCP) support for natural-language, cross-tool workflows - RealBrowser technology for browser-based load simulation that reflects real user experience, using roughly 30% less memory and CPU than legacy browser-based tools - Performance testing as code with full CLI support for pipeline integration - Dynamic infrastructure provisioning across 70+ on-demand cloud locations from seven providers, with native support for Kubernetes, OpenShift, and other container orchestrators - Comprehensive SAP coverage including GUI, Fiori, RFC, and IDoc protocols - Support for legacy systems through Remote Terminal Emulation - Network virtualization that simulates real-world bandwidth, latency, and packet loss across 3G, 4G, and WiFi conditions - Automatic test script updates when applications change NeoLoad is particularly well suited for enterprises undergoing digital transformation, organizations with complex SAP landscapes, and DevOps teams looking to shift performance testing earlier in the development cycle. Results and analytics are surfaced through detailed dashboards and reports, giving teams actionable insight into bottlenecks, response times, error rates, and infrastructure resource consumption. NeoLoad also integrates with APM platforms such as Dynatrace, AppDynamics, New Relic, and Datadog, version control systems including Git and SVN, and open-source load testing tools like JMeter and Gatling for consolidated analysis."
