Are you a Java developer and you've seen the fluent and modern specification frameworks available in other programming languages such as spock or jasmine and wondering why we can't have the same thing? Then Lambda Behave is made for you! It uses numerous Java 8 features in order to enable cleaner and more readable tests and specifications. This quickie will introduce the framework, explain why you would want to use it over junit and cover some of its cool features, including: * How to write fluent and clean specifications in your domain language * How to write data driven specifications * How to integrate these into your build tool or IDE * How IDE usage can influence library design for the better http://richardwarburton.github.io/lambda-behave/
