It runs automated acceptance tests written in a behavior-driven development (BDD) style. [15] Cucumber was originally written in the Ruby programming language. [7] [16] [8] and was originally used exclusively for Ruby testing as a complement to the RSpec BDD framework. Cucumber now supports a variety of different programming languages through ...
BDD suggests that software tests should be named in terms of desired behavior. [5] [7] Borrowing from agile software development the "desired behavior" in this case consists of the requirements set by the business — that is, the desired behavior that has business value for whatever entity commissioned the software unit under construction. [5]

In computer science, a binary decision diagram (BDD) or branching program is a data structure that is used to represent a Boolean function. On a more abstract level, ...
Acceptance test–driven development (ATDD) is a development methodology based on communication between the business customers, the developers, and the testers. [1] ATDD encompasses many of the same practices as specification by example (SBE), [2] [3] behavior-driven development (BDD), [4] example-driven development (EDD), [5] and support-driven development also called story test–driven ...
They can either be tested manually or automated as browser tests with tools like Selenium and Cucumber. [1] [2] It derives its name from the three clauses used, which start with the words given, when and then. [3] Given describes the preconditions and initial state before the start of a test and allows for any pre-test setup that may occur.
In both scenarios, dollar-cost averaging provides better outcomes: At $60 per share. Dollar-cost averaging delivers a $6,900 gain, compared to a $2,400 gain with the lump sum approach.
Test-driven development (TDD) is a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case.
