Conduct-Pushed Growth (BDD) is an Agile method that mixes requirement gathering, documentation and acceptance testing. You write human-readable sentences describing the options of your software and the way they need to work. Then you definitely implement this conduct utilizing a instrument that produces automated acceptance exams to confirm that the function is applied appropriately. Open supply .NET BDD instruments like SpecFlow are used to retailer the necessities as stay documentation and to carry out practical or acceptance exams.
This text presents a listing of open supply software program testing instruments to carry out Conduct-Pushed Growth (BDD) for the .NET platform and the C# language. For every instrument, you’ll get a small description of its options. Be at liberty to recommend any extra .NET BDD framework or useful resource that you just suppose ought to be included on this article. The instruments, listed below are BDDfy, BDD toolkit for .NET, Concordion.NET, Kekiri, LightBDD, Machine.Specs (Mspec), Nbehave, Nspec, Reqnroll, SpecFlow, SpecsFor, Storyteller, TickSpec, Xunit.Gherkin.Fast.

BDD toolkit for .NET
BDD toolkit for .NET is a light-weight .NET library for implementing BDD situations in pure C#. No enforcement of normal expressions. No strict conventions. As an alternative – shut integration with C# syntax and most utilization of its expressiveness. Because of you could get immediately productive and concentrate on the area you check.
BDD toolkit for .NET supplies:
* Fluent syntax to jot down exams in Given – When – Then fashion
* Right exceptions dealing with – all of assertions are checked even when an exception was thrown (extra information right here)
* Can be utilized with any check framework (xUnit, NUnit, MSTest)
* Era of readable check situations immediately from exams code (no semicolons, parentheses

Concordion.NET
Concordion.NET is a small open supply Conduct Pushed Growth (BDD) framework for C# and .NET that allows you to flip plain English descriptions of necessities into automated exams. A Concordion.NET executable specification consists of two components: a well-formed XHTML doc describing the anticipated conduct, and fixture code written in C# (a particular Concordion.NET extension of a NUnit exams) that finds concrete examples within the doc and makes use of them to confirm the system underneath check.
Because the Concordion.NET framework focuses on enterprise readable inputs, the specs are are so readable, they will double up as system documentation. They’re written in HTML, so might be simply hyperlinked right into a navigable construction. With these automated acceptance testing, you might be assured the documentation is at all times up-to-date.

Kekiri
Kekiri is an open supply .NET framework that helps writing low-ceremony BDD exams utilizing Gherkin language. Kekiri honors the conventions of the Gherkin cucumber language. Not like different BDD frameworks that impose course of overhead (administration of function information, customized tooling, and so on) Kekiri permits builders to jot down BDD situations simply as shortly and simply as they’d a “plain outdated” check. The ensuing state of affairs fixtures are concise, extremely moveable, and cling to Act, Organize, and Assert. IoC can be a first-class citizen encouraging testing object interactions in collaboration slightly than isolation.

LightBDD
LightBDD is an open supply Conduct-Pushed Growth check framework that gives the flexibility to jot down exams which are straightforward to learn, straightforward to trace throughout execution and summarize the check ends in person pleasant report, whereas permitting builders to make use of all the customary improvement instruments to take care of them. LightBDD supplies native help for refactoring, code evaluation and check working. It has straightforward to learn state of affairs definitions and state of affairs steps execution monitoring and time measurement, usable throughout longer check execution.
LightBDD supplies help for parameterized steps with sensible guidelines of inserting argument values to formatted step title. It additionally helps contextual state of affairs execution the place steps shares devoted context. Outcomes reviews might be produced in XML, HTML or Plain textual content format. It integrates with NUnit, xUnit and MsTest.TestFramework frameworks and supplies cross-platform help (.NET Framework / .NET Normal / .NET Core / UWP).

MSpec / Machine.Specs
MSpec or Machine.Specs is a Context/Specification framework geared in direction of eradicating language noise and simplifying exams. MSpec is known as a “context/specification” check framework due to the “grammar” that’s utilized in describing and coding the exams or “specs”. To help readability and take away as a lot “noise” as attainable, MSpec eschews the normal attribute-on-method mannequin of check building. It as a substitute makes use of customized .NET delegates.

NBehave
NBehave is an open supply framework for Behaviour-Pushed Growth (BDD) in ,NET. It was impressed by JBehave and runs on high of a ‘typical’ Unit Testing framework like Nunit, mbunit, xunit and mstest.
Web site: https://github.com/nbehave/NBehave
NSpec
NSpec is an open supply testing framework for C# impressed by Mocha and RSpec. In NSpec, there isn’t any want for entry modifiers on exams, and no want to brighten check strategies with attributes. It has some easy assertions, however it’s best to actually simply use FluentAssertions, or Shouldly, or one other assertion framework. You’ll be able to construct your individual assertions by utilizing extension strategies. NSpec, as a member of the xSpec household, doesn’t make use of attributes and as a substitute obtains the identical consequence with a set of expectations robotically created by code.

Reqnroll
Reqnroll is an open-source .NET check automation instrument to observe Conduct Pushed Growth (BDD). Reqnroll is a .NET port of Cucumber and it’s primarily based on the SpecFlow framework and code base. You’ll find extra details about the objective of the Reqnroll undertaking and the motivations to create it on the Reqnroll web site.
Reqnroll permits writing executable specs for BDD utilizing Gherkin, the widely-accepted function file specification format. With you could outline the necessities utilizing Given-When-Then fashion situations and switch them to automated exams in an effort to confirm their implementation.
Reqnroll works on all main working techniques (Home windows, Linux, macOS), on all generally used .NET implementations (together with .NET Framework 4.6.2+ and .NET 8.0). For executing the automated situations, Reqnroll can use MsTest, NUnit or xUnit. On Reqnroll tasks you’ll be able to work utilizing Visible Studio 2022, Visible Studio Core and Rider, however you may as well use Reqnroll with none IDE.
