Real world testing & Refactoring with a Kotlin twist

Hello everyone

We are really excited to announce our first gathering for 2018 at GDG Android Athens, that will take place on 31st of January at Innovathens powered by Samsung (http://www.innovathens.gr/).

In our this meetup, Kostas from Advantage FSE will talk about Refactoring with a Kotlin twist, while our second speaker Dimitris from Novoda team will discuss about a real world testing with BDD & Espresso.

Special thanks to Advantage FSE (http://www.afse.eu/) for sponsoring the space, e-food (https://www.e-food.gr/) for the pizzas and Pollfish (http://www.pollfish.com/) for the beers!

1) Title: Refactoring with Branch by Abstraction and a Kotlin twist.

Description: Making large-scale changes to your codebase, like replacing a deprecated library with a new one, can be both fun and frightening. While everyone wants to be up to date with the current best practices, no one wants the merge hell that may follow. This session presents Branch by Abstraction, a technique which allows a system to change incrementally, and how a tiny Kotlin trick helps to implement it in a timely manner.

2) Title: Real world testing with BDD & Espresso.

Description: Testing used to be seen as a “good to have” or even a burden in the development process. In this talk we’ll see how Behaviour Driven Development can help improve the quality of our products and also get the whole team to work closer. We will also see the toolset available to implement our testing solutions.

Next-day Workshop: Introduction to the Ethereum Ecosystem

This is an introductory workshop aimed mostly at developers who have little to no experience with the Ethereum tech stack and are interested in learning how to interact with its blockchain using the available tools. We will show how you can deploy basic smart contracts and how to interact with them, both directly and through dApps(decentralized applications). Everything will take place on the Ropsten testnet. After participating, you’ll have plenty of knowledge that will help you use your own wallet, make transactions with it, participate in ICOs and even trade cute digital pets!
Do all of the above sound completely gibberish but also very interesting to you? Take part in the workshop to find out what the hype is all about.

** Prerequisites **
Adequate understanding of basic computer science and internet concepts are a prerequisite for attending the workshop. Mostly recommended for people with developer experience. You are encouraged to bring your own laptops in order to follow the examples.

** Schedule **
11:30-12:00 Setup and use an Ethereum wallet
12:00-12:30 Create and deploy your own ERC20 token
12:30-13:00 Participating in ICOs
13:00-13:30 Interacting with dApps through Metamask
