Attendees will discover that Cucumber’s ability to map stories and acceptance criteria to automated functional tests makes it an ideal BDD tool. The combination of instruction and application in this class will prepare your team for success in implementing and executing tests using Cucumber.
This course is considered a Private versions that can be done with the Java or .NET versions of Cucumber.
