Varighet: 3 dager fra kl 09:00 - 16:00

Pris: 16900

Kurskategori: Applikasjons utvikling

Kursdatoer er ikke helt avklart ennå, men kontakt [email protected] for påmelding!

The course covers writing unit, integration, and end-to-end tests, showing how you can guard and enforce the rules of your architecture. We show the ways TDD helps with building and improving sustainable architecture. JUnit and Spock frameworks are used in the examples, however, the knowledge gained during the course is easily applicable to other testing libraries.

During the course, attendees will learn about the challenges with maintaining a huge number of tests in a project, and how to avoid usual pitfalls related to that.

Target audience: Developers, Team Leads, Architects
