In questo workshop cercheremo di sviluppare from scratch un'applicazione scritta in Kotlin che si basa sul framework Spring Boot. Proveremo a seguire un approccio TDD e vedremo passo passo come scrivere acceptance test, integration test e unit test. Bonus: dovremo interagire con un servizio esterno per essere più vicini alla vita reale di un'applicazione web I partecipanti potranno apprendere i rudimenti di Kotlin e di Spring Boot ma sopratutto una panoramica di come e quando scrivere le varie tipologie di test.

● Two people step up to the keyboard and begin
developing
● Regular switching

● Everyone present is expected to follow what is
going on, and make helpful suggestions
● The pair at the keyboard should explain what
they are doing so everyone can follow

point?
