Blazemeter vs. Loadium Performance Testing Platform. Thanks, Krishna Scalability testing is performed to check whether the website which is developed is capable enough to handle the large loads. Performance testing is an umbrella term for load testing and stress testing. In this webinar, Tim Koopmans talks about continuous load testing inside the CI/CD lifecycle to measure performance, availability, reliability, and scalability. Load Testing: Load testing is proposed to test the system by continually and firmly raising the load on the system till the time it approaches the threshold limit. That being said, most of such issues testers encounter have quite clear-cut solutions, which is why we have summarized some of the common Selenium automation testing challenges, along with their solution. Load testing includes modeling and testing the software application for various load scenarios and user profiles. LoadStorm is a cloud load testing solution to find the scalability of web or mobile applications. This makes it one of the best load testing tools available in the market. Spike testing checks whether the API is able to stabilize and return to normal functioning after that. The following are the different phases of load and scalability testing for a Web application: Architecture Validation - tests the scalability of the architecture early in the development of a Web application, presumably after a prototype of the application has been created that can generate transactions to touch all tiers of the application. Load testing could be done manually as well as by using an automation testing tools: 1. Spike testing. Here the term ‘load’ refers to the number of users using the website. 360logica makes use of open source and commercial tools to execute performance testing. ab: slow and single threaded, written in C. apib: most of the features of ApacheBench (ab), also designed as a more modern replacement, written in C. baloo: expressive end-to-end HTTP API testing made easy, written in Go (golang). Performance Testing Types: There are two important performance testing types: load testing and stress testing. Start with Why: How to Write Requirements for API Load Testing. And in some cases, load testing works at a predefined load level, usually the highest load that the system accepts. Performance Testing: In software, performance testing (also called Perf Testing) determines or validates the speed, scalability, and/or stability characteristics of the system or application under test. Load testing determines the point at which the application crashes, while scalability tries to identify the reason for application crash and take steps to resolve the issue. Cloud testing is the process of testing the performance, scalability, and reliability of web applications in a cloud computing environment. The type of performance test to validate the scalability of the application is called scalability testing. Stress Testing vs Load Testing. Scalability testing is the part of non-functional testing where a software application’s performance is tested in terms of its non-functional capability to scale up or scale down the user request load or other such performance attributes.. Smoke Testing is used for testability. Load Testing involves placing a maximum load on the developed applications at one go, while scalability testing involves gradually increasing the load over a period of time progressively. The range of performance testing extends from load testing, capacity testing, stress testing, volume testing, spike testing, reliability testing, scalability testing, etc. In this talk, I'll briefly discuss load testing strategies, then dive into how to DIY with Python using Corey Goldberg's open source library multi-mechanize as well as how to gather performance data from your tests.
