easyb is a behavior driven development framework for the Java platform. By using a specification based Domain Specific Language, easyb aims to enable executable, yet readable documentation.
In the fully expansive (or LCF-style) approach to theorem proving, theorems are represented by an abstract type whose primitive operations are the axioms and inference rules of a logic. Theorem proving tools are implemented by composing together the inference rules using ML programs. This idea can be generalised to computing valid judgements that represent other kinds of information. In particular, consider judgements (a,r,t,b), where a is a set of boolean terms (assumptions) that are assumed true, r represents a variable order, t is a boolean term all of whose free variables are boolean and b is a BDD. Such a judgement is valid if under the assumptions a, the BDD representing t with respect to r is b, and we will write a r t --> b when this is the case. The derivation of "theorems" like a r t --> b can be viewed as "proof" in the style of LCF by defining an abstract type term_bdd that models judgements a r t --> b analogously to the way the type thm models theorems |- t.
RSpec is a Behaviour Driven Development framework for Ruby. It provides two frameworks for writing and executing examples of how your Ruby application should behave:
* a Story Framework for describing behaviour at the application level
* a Spec Framework for describing behaviour at the object level

Context Specification is a lot more than merely a new way to write tests. Although it was conceived around the same time as Behavior-Driven Development (BDD), and probably inspired by some of the BDD concepts, it is quite different.

Behavior driven development?
Behavior driven development (or BDD) isn't anything new or revolutionary-- it's just an evolutionary offshoot of test driven development, in which the word test is replaced by the word should. Semantics aside, a lot of people have found that the concept of should is a much more natural development driver than the concept of testing. In fact, when you think in terms of behavior (i.e. shoulds) you'll find that writing specifications is easier to do first, which is the intent of test driven development in the first place.

Dadi est un répertoire en évolution constante de bases de données en consultation gratuite ; certaines fournissent aussi le document primaire mais le plus souvent ce dernier est payant.
I first used Behaviour-Driven Development in a relatively disciplined way when writing Walrus. BDD is an incredible safety net for a beginner (Walrus was my first ever real Ruby project; previously I had only written 10-line scripts). It allows you to ens

Let's focus on the tooling around testing with functional languages. What kind of options do we have? In the Haskell world just as the F# world, there are several tools at our disposal to do this. * HUnit A traditional xUnit testing framework for unit testing. Analogous to such frameworks as xUnit.net, NUnit and MbUnit in the .NET world. * QuickCheck A program in which the developer provides a specification of the program, in the form of properties which functions should satisfy, and then tests that the properties hold in a large number of randomly generated cases that QuickCheck provides. There are many variants of this tool for most functional languages including F# (FsCheck), Erlang, Scala, Java, Python, Standard ML and others. Today we're going to focus on HUnit as part of developing an API in Haskell.
A tool for testing Scala and Java software
OSI Certified Open Source Software
ScalaTest is a free, open-source testing tool for Scala and Java programmers. It is written in Scala, and enables you to write tests in Scala to test either Scala or Java code. It is released under the Apache 2.0 open source license.
Because different developers take different approaches to creating software, no single approach to testing is a good fit for everyone. In light of this reality, ScalaTest is designed to facilitate different styles of testing. ScalaTest provides several traits that you can mix together into whatever combination makes you feel the most productive.
