What is Cucumber used for?
Cucumber is a behavior-driven development (BDD) framework written in Ruby. The framework’s name is derived from the structure of cucumber plants: a long vine that trails down to the ground and uses its roots to absorb water and nutrients. In a similar way, Cucumber uses language-based tests to ensure that your application is absorbing the right information from users and giving them what they need. It is primarily used for writing acceptance criteria, but can also be used for writing executable specifications or acceptance tests.
