Load testing tools analyze the entire OSI protocol stack whereas most regression testing tools focus on GUI performance. For example, a regression testing tool will record and playback a mouse click on a button on a web browser, but a load testing tool will send out hypertext the web browser sends after the user clicks the button.
Load testing is the simplest form of performance testing. A load test is usually conducted to understand the behavior of the system under a specific expected load. This load can be the expected concurrent number of users on the application performing a specific number of transactions within the set duration.
Load testing tool WebLOAD combines performance, scalability, and integrity as a single process for the verification of web and mobile applications. [ 1 ] [ 2 ] [ 3 ] It can simulate hundreds of thousands of concurrent users making it possible to test large loads and report bottlenecks, constraints, and weak points within an application.
NeoLoad (load and stress testing) is an automated performance testing platform for enterprise organizations continuously testing from APIs to applications. It provides testers and developers automatic test design and maintenance, the most realistic simulation of user behavior, fast root cause analysis and built-in integrations with the entire software development lifecycle toolchain.
There is little agreement on what the specific goals of performance testing are. The terms load testing, performance testing, scalability testing, and volume testing, are often used interchangeably. Real-time software systems have strict timing constraints. To test if timing constraints are met, real-time testing is used.
See the main article at Performance engineering. Performance engineering is the discipline encompassing roles, skills, activities, practices, tools, and deliverables used to meet the non-functional requirements of a designed system, such as increase business revenue, reduction of system failure, delayed projects, and avoidance of unnecessary usage of resources or work.
In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:
The software is designed to be used as a load testing tool for analyzing and measuring the performance of a variety of services, with a focus on web applications, APIs, and microservices. Gatling was mentioned twice in ThoughtWorks Technology Radar, in 2013 and 2014, [ 2 ] "as a tool worth trying", [ 2 ] with an emphasis on "the interesting ...
