Программа встречи

– Performance testing: the way to make a true load (Izzet Mustafaiev)

If you heard about web-scale or have a requirement to survive under web-scale or you just would like to prepare your application to handle an X effect this topic is for you. During a presentation you will understand aspects and caveats of performance testing, nuances of performance testing of Java based web applications. As a practical part you will get a brief overview of existing tools and will get a guide of using Gatling as a tool to make a load for your application. Gatling is an open source tool for performance loading written in Scala and provides comprehensive DSL for load scenario specification.

– Spock: live long (code short) and prosper (Yaroslav Yermilov)

JUnit is in the game for a years and can be considered as the most popular Java library ever. But when have you heard about new features in JUnit last time? Isn’t it time to look at something new and modern?
For example, Spock — beautiful and highly expressive testing and specification framework. As many citizens of Groovy world, it’s in the same time highly compatible with existing Java infrastructure and, thanks to Groovy power, has amazingly clean and powerful DSL.
In this talk, we will look at variety of Spock feature and try to find answer how does testing beyond JUnit may look like.

Активных участники встречи, ждут лицензии от JetBrains и билеты на JavaDay Kyiv.

In this workshop, we will focus and learn some key technical practices that will help us evolve applications based on the feedback cycles that agile development heavily relies upon. We will learn design principles and practices that help reduce risk involved often in evolving software. Read more…
