Performance testing validates an application's responsiveness, stability, and other quality attributes under various workloads. It involves load testing, stress testing, endurance testing, spike testing, volume testing, availability testing, and scalability testing. The key parameters analyzed are response time, throughput, and memory utilization. Performance testing helps determine an application's speed, scalability, stability, and ability to handle changes in load and traffic over time.

This document discusses performance testing and provides information on several related topics: - It defines performance, load, and stress testing and explains their differences. - It outlines why performance testing is important, when it should be conducted, and what aspects of a system should be tested. - The performance testing process is described as involving planning, creating test scenarios and scripts, running tests, monitoring tests, and analyzing results. - Automated performance testing is presented as more effective than manual testing due to issues with resources, coordination, and repeatability when using human testers.

Load testing simulates multiple users accessing an application simultaneously to evaluate performance under different load scenarios. There are three main types of load testing: 1. Performance testing gradually increases load to determine the maximum number of users/requests per second an application can handle. 2. Stress testing pushes load beyond normal limits to identify the breaking point and ensure error handling. 3. Soak testing subjects an application to high load over an extended period to check for resource allocation problems, memory leaks, and server overloading. The tool JMeter is commonly used for load testing and allows simulating many users and transactions. It can test HTTP, databases, and other components. Plugins extend its functionality and distributed testing improves load

Slides from the workshop I conducted on "Client-side Performance Testing". Abstract of the workshop: In this workshop, we will see the different dimensions of Performance Testing and Performance Engineering, and focus on Client-side Performance Testing. Before we get to doing some Client-side Performance Testing activities, we will first understand how to look at client-side performance, and putting that in the context of the product under test. We will see, using a case study, the impact of caching on performance, the good & the bad! We will then experiment with some tools like WebPageTest and Page Speed to understand how to measure client-side performance. Lastly - just understanding the performance of the product is not sufficient. We will look at how to automate the testing for this activity - using WebPageTest (private instance setup), and experiment with yslow - as a low-cost, programatic alternative to WebPageTest.

Modern software products tend to have a rich UI that supports many user workflows, all of which need to be covered in testing. Agile organizations quickly discover that manual end-to-end testing neither supports their velocity nor provides respectable regression coverage. A common progression is to move from fully manual testing to record/replay, then to Selenium IDE style tests, then to automation based on Selenium WebDriver, perhaps with a BDD overlay. Daria Mehra has practiced this approach and shares her experience. She compares the Selenium style of automation to an alternative—crowdsourced test execution— which provides all the benefits of test automation, including continuous integration. This approach allows non-coders to express test cases in natural language, avoids the dependency on UI implementation, adds a “human eye” advantage, and provides the ability to massively parallelize tests for fast execution. Learn the pros and cons of end-to-end, UI-based test automation via Selenium compared to crowdsourcing. Find out how you can assess the suitability of these testing approaches for your needs.

This document discusses teswiz, an open source framework for automating real-user scenarios across multiple apps, devices, users, and platforms. It can simulate user actions and behavior to test web, mobile web, Android, iOS, Windows, MacOS and Linux applications. Teswiz uses Cucumber, Appium, Selenium and other tools and supports features like multi-device testing, visual testing with Applitools, and generating reports with ReportPortal. The document provides instructions on getting started with teswiz and links to its GitHub page.

The document discusses visual validation testing as a missing piece of the automation testing pyramid. Visual testing is important but challenging as it is typically done manually, which is tedious, error-prone, and difficult to scale. Automating visual testing can help by taking screenshots of expected user interfaces and comparing them to actual screenshots. However, automating also poses challenges around false positives/negatives, maintaining baselines, and accounting for product changes. The document promotes using artificial intelligence in visual test automation to help address these challenges and advocates for including visual testing in an organization's overall quality and automation strategy.

In this talk, we will talk about, and see examples of various types of patterns you can use for: - Build your Test Automation Framework - Test Data Management - Locators / IDs (for finding / interacting with elements in the browser / app) Using these patterns you will be able to build a good framework, that will help keep your tests running fast, and reliably in your CI / CD setup!
