Performance testing is an important part of Agile development to ensure software meets performance goals. There are several types of performance testing including load testing to verify behavior under normal and peak loads, stress testing to validate behavior beyond normal loads, and capacity testing to determine how many users a system can support. Performance testing should be integrated into the Agile process through techniques like code optimization, early bottleneck detection, and resolving issues to deliver high quality software on schedule.
Srivalli Aparna - The Blueprints to SuccessNeotys_Partner
Since its beginning, the Performance Advisory Council aims to promote engagement between various experts from around the world, to create relevant, value-added content sharing between members. For Neotys, to strengthen our position as a thought leader in load & performance testing. During this event, 12 participants convened in Chamonix (France) exploring several topics on the minds of today’s performance tester such as DevOps, Shift Left/Right, Test Automation, Blockchain and Artificial Intelligence.
Performance testing determines how responsive and stable a system is under different workloads. It tests for speed, scalability, stability, and ensures a positive user experience. Types of performance testing include load testing to evaluate behavior under expected loads, and stress testing to find upper capacity limits. Key metrics measured are response time, throughput, and resource utilization. Performance testing involves planning test goals, methodology, implementation, validation of results, and interpreting results. Common tools used for performance testing are JMeter, LoadRunner, and Webload.
Career Opportunity--Database Product Test EngineerHema Latha

ENASE 2013 - SEM - (Francia) From Functional Test Scripts to Performance Test...Federico Toledo
When modernizing systems the software is migrated from one platform to another. There are big risks concerning the performance the system should have in the new platform. A new system cannot take more time to perform the same operations than the previous one as the users will refuse it. Therefore, the preventive performance test is crucial to guarantee the success of the modernization project. However, the automation tasks for performance testing are too demanding, in terms of time and effort, as the tools work at a communication protocol level. Though not free, the functional testing automation is easier to accomplish than the performance testing automation as the tools work at a graphic user interface level; the tools are therefore more intuitive and they have to handle less variables and technical issues. In this article we present a tool that we developed for industrial usage to automatically generate performance tests scripts from automated functional tests. The tool has been used in several projects in the industry, achieving important effort savings and improving flexibility.
Comprehensive Performance Testing: From Early Dev to Live ProductionTechWell
Although the idea of doing performance testing throughout the software lifecycle sounds simple enough, as soon as you try to combine the concepts of “always testing” (in dev, pre-prod, and production) with “limited time and resources” and throw in the word “comprehensive,” the challenges can be monumental. Quickly the “how” of it emerges as the most important question—and one worth focusing on. Brad Stoner tackles this topic by explaining how he has been able to solve this seemingly impossible puzzle by applying various approaches such as early and often, learning when to say no, and seriously, I did say no—and more. Brad shares concrete examples of how he has successfully implemented full lifecycle performance testing at several companies. Join Brad to learn what performance tests to run at each development and delivery stage—from a simple load profile on a single server to full-scale soak tests over several days.

This document presents a proof of concept for automating tests of a software under test (SUT) using Selenium WebDriver with either Java or JavaScript technologies. It evaluates Selenium with Java using JUnit in Eclipse or with JavaScript using Protractor. Both approaches are found capable of test automation, but Protractor is deemed more suitable since the SUT uses AngularJS and JavaScript is already established for the project. The document describes the environment, setup, features, some initial test cases performed, and concludes that Protractor would achieve better results due to its specificity for AngularJS.

"Fast / Resilient / .NET – What to Choose?" Serhiy KalinetsFwdays
For a long time It's rather common to see the words “.NET” and “microservices” in a single sentence. Statements like “.NET is Windows only” surprise us and the only reaction is “are you really a .NET developer?”. Everyone makes microservices, runs them in Kubernetes and clouds and that all looks good.
However after a closer look at the code most of that coolness disappears. After some zooming microservices become micro monoliths. Practices and approaches put into the heads of young developers by dotnet veterans (who remember stuff like Remoting or COM / DCOM) don’t give up. The result is monstrous overcomplicated (micro)services that don’t necessarily work fine. For some reason, the area of speed and resilience very often is uncovered.
During this session Serhii will show typical errors making services vulnerable to unexpected conditions. We will break services then fix them, slow down, speed up, stabilise and so on.
Visit this session – its going to be fun. And maybe you’ll recognize your own services among our examples and will fix them proving that .NET can be used to build fast and recilillent solutions.
Code review automation and functional tests on CarrefourDenis Santos
Jenkins is used to automate the software development lifecycle including builds, tests, deployments, and more. A deployment pipeline promotes code through development, QA, and production environments running tests at each stage. Cucumber, Capybara, and Selenium are used for behavior-driven development and automated functional tests across different browsers and machines in parallel. SonarQube analyzes code quality after each build and will stop the pipeline if issues are found, reporting them to the development team.

The document discusses quality assurance and testing in software development. It recommends establishing a quality assurance framework that incorporates source code management, continuous integration, code reviews, and continuous inspection tools like SonarQube. This helps automate the development process, reduce technical debt, and prevent bugs by finding and fixing issues early. Tracking key metrics also allows measuring the costs of quality problems versus prevention activities.
The document discusses various code quality metrics that can be used to understand software quality, including defects density, unit test density, code and test coverage, cyclomatic complexity, fan-in and fan-out, and WTFs per minute. While metrics can help identify issues, they cannot determine the precise cause. Metrics should be used carefully to avoid incentivizing behaviors like hiding bugs. Maintaining pride in craftsmanship is important for quality.

" Performance testing for Automation QA - why and how " by Andrey Kovalenko f...Lohika_Odessa_TechTalks
Performance testing is important to verify an application's behavior under normal and peak load conditions. It determines how many users an application can support while meeting performance goals. Performance testing is done after functional testing using automated scripts. There are two main approaches to converting automated tests to performance tests: 1) modifying existing automation scripts to measure response times and run in parallel to simulate load; or 2) using a tool like HP LoadRunner that can convert automated tests into performance tests that can simulate load and generate reports. Setting up monitoring of system resources and the application is important for any performance testing approach.

Небольшое замечание о презентации – мы затронем самые базовые вещи, не будет обсуждения хитрых метрик производительности и вопросов, какой показатель лучше презентовать менеджерам – среднее или верхний квартиль или «10 вещей, которые вы точно забудете в своём первом перформанс проекте» – все будет сильно проще ) Постараемся ответить на вопросы – зачем на нужно тестирование проихводительности и как его запустить в нашем модном agile проекте)
Итак, тема нашего обсуждения - тестирование производительности как часть agile процесса разработки продукта. Соответственно, прежде чем начать, определимся, что такое тестирование производительности.
Сейчас будет немного определений и, возможно, занудной классификации ) Прошу меня заранее простить.
Не мудрствуя лукаво, обратимся к определению из словаря ISTQB (International SW testing qualification board). Итак – тестирование производительности – это процесс тестирование, направленный на определение производительности продукта. А производительность – это одна из подхарактеристик качества - эффективности, которая является интуитивно понятной.
Зачем нужно тестирование производительности?
Гугл из года в год приводит результаты своих исследований, в которых указывает, что клиент, прождавший более трёх секунд после нажатия на ссылку и не дождавшийся загрузки страницы, с большой вероятностью выберет другой сайт. Мобильные устройства по-прежнему требуют от приложений умения работать на ограниченных ресурсах и в условиях плохих каналов связи. Базы данных бизнес-решений занимают терабайты, а клиент по-прежнему ждёт, чтобы отчёт формировался побыстрее. Именно поэтому в последнее время тестирование производительности становится всё более востребованным – потому что может принести вашей компании дополнительную прибыль
Несколько слов о тестировании производительности в целом.
Тестирование производительности является видов нефункционального тестирования и подразделяется на несколько видов –
Load testing – создаём ОЖИДАЕМУЮ нагрузку (количество пользователей и транзакций), определяем время отклика системы для различных операция, сравниваем с заранее определёнными KPI, проверяем потребляемые ресурсы системы
Stress Testing – даём нагрузку сверх ожидаемой и смотрим, что произойдёт с системой (упадёт, заберёт все ресурсы, начнёт тормозить). Убираем нагрузку, смотрим, вернулась ли система к нормальному поведению
Capacity testing – проверяем, сколько пользователей выдержит система, продолжая находиться в заданных рамках производительности.
На самом деле можно выделить ещё несколько подвидов тестирования производительности, но для нас – этого будет достаточно.
Кстати, предупреждаю сразу – все названия, произнесённые мною, трактуются по-разному различными специалистами. Некоторые, например, меняют местами performance и load testing.
Жизненный цикл тестирования производительности, в общем-то, ничего не отличается от любого другого вида тестирования
Планирование – Подготовка – Выполнение – Анализ-при необходимости повторное Выполнение
Планирование - анализируем структуру приложения, выявляем узкие места, определяем мониторы, которые нужно будет контролировать определяем KPI
Подготовка – готовим тестовые данные, тестовую лабораторию, пишем и отлаживаем скрипты и сценарии
Выполнение – очень необычно – но выполняем наши сценарии и собираем данные мониторов
Анализ – ещё более необычно – анализируем массив данных, полученных на предыдущем этапе. Готовим отчёты, анализируем причины проблем, открываем дефекты
НО
Если вы обратили внимание – то всех определениях использовались слова «пользователи» и «нагрузка». Отсюда достаточно просто сделать вывод, что тестирование производительности – это ВСЕГДА (ну ладно, почти всегда) автоматизированное тестирование (поскольку нам нужно эмулировать работу многих пользователей) с использованием инструментов для генерации нагрузки (которые стоят обычно немаленьких денег).
Тестирование производительности нуждается для проведения в соответствующей аппаратной инфраструктуре, её настройке и мониторинге. Можно, конечно, попробовать провести тесты на окружении, не похожем на продакшн, а потом экстраполировать результаты – но, как показывает практика, сделать это качественно получается достаточно редко.
И, наконец, для проведения анализа результатов неплохо иметь инженера, обладающего хотя бы зачатками знаний в области математической статистики, значит, нужно привлекать к процессу «дорогого» инженера.
К тому же, тестирование производительности - длительный процесс – тесты нужно написать, отладить, создать тестовую среду, прогнать тест (тест может длиться несколько дней или недель) и проанализировать результаты.
Итого, можно смело констатировать, что тестирование производительности - это дорогой (нужен Automation QA, разбирающийся в коде, аппаратных и программных составляющих и имеющих математический бэкграуд+железо) и долгий процесс. Запоминаем этот факт и идём дальше.
Теперь быстренько вспоминаем, что такое Agile. Agile – это манифест, определяющий подходы к разработке ПО. Не буду вдаваться в подробности и различные техники – но в любой методологии Agile основным принципом является частая поставка рабочего программного обеспечения. Два основных слова – частая и рабочего. Это приводит нас к тому, что за две недели (как обычно длится итерация) нам нужно провести полный цикл тестирования – в том числе и тестирования производительности. А как мы видели на предыдущем слайде – тестирование производительности - это длительный и дорогой процесс( Более того, возникает ещё один вопрос – поскольку тестирование производительности - это дорого, то неэффективно тратить ресурсы на систему, не прошедшую функциональное тестирование – ваши дорогостоящие тесты просто «свалятся» из-за функциональных багов.
Обычно после таких размышлений agile разработчики с опаской относятся к тестированию производительности и если и проводят его - то в минимальном объёме на релизной версии продукта, а то и после релиза. К чему это приводит? Клиент получает неторопливо работающее приложение, падающее при нагрузке в 50 пользователей и сжирающее все доступные на сервере ресурсы.
Но не всё так плохо. Давайте попробуем понять, как же нам встроить тестирование производительности в Agile и не потратить на это много ресурсов.
Итак, перед нами возникает несколько вопросов – Когда проводить, какие преимущества мы получим от связки performance testing&Agile и сколько это будет стоить?
Небольшое предупреждение – всё дальнейшее – не более, чем мой личный опыт и и вполне возможно вы встретите на просторах интернета аргументированные мнения, что Agile и Performance testing несовместимы
Вопрос номер раз – КОГДА?
Не ждите, пока ваше приложение «встанет на ноги». Чем раньше, тем лучше, поскольку, как мы все знаем, чем раньше мы нашли дефект, тем дешевле его исправить! Мы помним, что по Agile уже к концу первой итерации мы должны получить рабочий прототип – вот окончание первой итерации - время для нас запустить первые тесты. Не придумываем ничего нового – те же стандартные уровни тестирования – модульное, интеграционное, системное, приёмочное. Что тестировать, если приложение ещё сырое? У приложение ещё нет UI и API– не беда, займитесь тестированием на уровне компонентов, анализом кода, определением KPI. Появились первые элементы UI или первые методы API – займитесь первыми тестами для них.
Разработчики сломали ваши тесты – пока они чинят, займитесь single-user тестированием на больших объёмах данных, часто даже такой вид тестирования позволяет выявить узкие места.
Как видно на рисунке на любом уровне разработки и функционального тестирования есть место для вашей деятельности.
Постарайтесь «отставать» с запуском ваших сценариев от команды функционального тестирования на одну итерацию - так вы будете точно знать, какая функциональность готова к вашему тестированию и не будете тратить напрасно время, пытаясь понять, почему валятся ваши замечательные тесты.
Теперь к «плюшкам», которые мы можем получить внедрив performance testing в Agile. Запоминаем, чтобы рассказать потом менеджерам
Применение гибкого тестирования производительности позволяет снизить ряд рисков, возникающих при разработке приложений и положительно влияет на качество:Оптимизация кода: Оптимизация на уровне модулей происходит в начале разработки. Таким образом, издержки на исправления значительно ниже, чем если бы проблемы были выявлены на поздних стадиях.Отказы приложения: Снижается риск отказа приложения, вызванный такими факторами, как утечки памяти, взаимоблокировки в СУБД и “Хард-код”.Раннее обнаружение узких мест: Снижается трудоемкость и продолжительность тестирования производительности, а также уменьшается необходимость в повторном тестировании.Даты релиза: Тестирование каждую итерацию приводит к осведомленности о производительности приложения в любой момент времени. Благодаря этому, появляется больше шансов выпустить релиз в срок.
Проведение тестов на реальных данных и сценариях: поскольку Agile исповедует принцип Business people and developers must work together daily throughout the project – у вас есть отличная возможность получить от клиентов реальные сценарии использования продукта и наборы данных – поверьте, в тестировании производительности это дорого стоит. Можно рассказать массу занимательных историй, как были получены отличные отчёты по производительности на синтетических данных и что потом имели сказать нам клиенты, получившие продукт, не справлявшийся с их задачами.Проблемы производительности: Уменьшается количество проблем производительности на последующих этапах – а это нам даёт что? Правильно – громадное уменьшение стоимости исправления этих дефектов.
Итак – как прикрутить performance тестирование к Agile процессу и что нам это даёт - в общих чертах понятно.
Дорогие инструменты и оборудование для тестирование производительности!
Инструменты – наберите в поисковике free load testing tools – мне кажется, выбор достаточен – вот те, которые я нашёл по первой ссылке. Кстати, любой из них отлично встраивается в систему Continuous Delivery – например, в Jenkins, которая тоже бесплатная.
Сервера – это, конечно, дорого и нужно – но может быть, для вашего приложения для начала хватит мощности обычного десктопа, чтобы эмулировать 300 пользователей? По собственному опыту могу сказать – на первое время хватит.
Да и аренда машинного времени в облаке позволит вам минимизировать ваши затраты на организацию своей лаборатории по тестированию производительности.
Отдельно хотел бы остановится на коммерческом продукте от моей любимой компании HP, которым пользуемся мы в своей деятельности – LoadRunner от компании HP
Основные моменты, по которым вы будете его использовать –
Комьюнити версия – вся функциональность до 50 одновременных пользователей бесплатно
Функционал труклайент – позволяет вам создавать скрипты для нагрузочного тестирования чего угодно, имеющего web-интерфейс, методом тыка.
Интеграция с Selenium и Unit-фреймворками – через возможность использования в виде скриптов кода на C# и Java.
Инструмент автоматического анализа полученных результатов - позволяет делать качественные отчёты для стейкхолдеров, даже не обладая продвинутыми знаниями в нагрузочном тестировании и математической статистике
Итак, вы можете найти для себя инструмент, который позволит вам, имея минимальный опыт, быстро (решая проблему с короткими итерациями Agile) и недорого (решая проблему с ограниченным бюджетом) внедрить тестирование производительности в ваш проект и избежать многих проблем в дальнейшем.
Напоследок – думаю, я не сказал сегодня ничего, что вы не знали – но надеюсь, что помог вам посмотреть по-другому на привычные вещи и сделать шаг вперёд)
Всем спасибо за терпение и готов ответить на вопросы, если они у вас появились
