BDD toolkit for .NET
BDD toolkit for .NET is a light-weight .NET library for implementing BDD eventualities in pure C#. No enforcement of normal expressions. No strict conventions. As a substitute – shut integration with C# syntax and most utilization of its expressiveness. Due to that you would be able to get immediately productive and deal with the area you check.
BDD toolkit for .NET supplies:
* Fluent syntax to put in writing assessments in Given – When – Then model
* Appropriate 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 eventualities straight from assessments code (no semicolons, parentheses

Concordion.NET
Concordion.NET is a small open supply Conduct Pushed Improvement (BDD) framework for C# and .NET that allows you to flip plain English descriptions of necessities into automated assessments. A Concordion.NET executable specification consists of two elements: a well-formed XHTML doc describing the anticipated habits, and fixture code written in C# (a particular Concordion.NET extension of a NUnit assessments) that finds concrete examples within the doc and makes use of them to confirm the system below check.
Because the Concordion.NET framework focuses on enterprise readable inputs, the specs are are so readable, they’ll 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 assessments utilizing Gherkin language. Kekiri honors the conventions of the Gherkin cucumber language. In contrast to different BDD frameworks that impose course of overhead (administration of characteristic recordsdata, customized tooling, and many others) Kekiri permits builders to put in writing BDD eventualities simply as rapidly and simply as they’d a “plain previous” check. The ensuing state of affairs fixtures are concise, extremely transportable, and cling to Act, Organize, and Assert. IoC can also be a first-class citizen encouraging testing object interactions in collaboration fairly than isolation.

LightBDD
LightBDD is an open supply Conduct-Pushed Improvement check framework that gives the power to put in writing assessments which are simple to learn, simple to trace throughout execution and summarize the check ends in consumer pleasant report, whereas permitting builders to make use of all the normal growth instruments to take care of them. LightBDD supplies native assist for refactoring, code evaluation and check operating. It has simple to learn state of affairs definitions and state of affairs steps execution monitoring and time measurement, usable throughout longer check execution.
LightBDD supplies assist for parameterized steps with sensible guidelines of inserting argument values to formatted step identify. It additionally helps contextual state of affairs execution the place steps shares devoted context. Outcomes experiences might be produced in XML, HTML or Plain textual content format. It integrates with NUnit, xUnit and MsTest.TestFramework frameworks and supplies cross-platform assist (.NET Framework / .NET Customary / .NET Core / UWP).

MSpec / Machine.Specs
MSpec or Machine.Specs is a Context/Specification framework geared in the direction of eradicating language noise and simplifying assessments. MSpec is known as a “context/specification” check framework due to the “grammar” that’s utilized in describing and coding the assessments or “specs”. To assist readability and take away as a lot “noise” as potential, 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 Improvement (BDD) in ,NET. It was impressed by JBehave and runs on prime 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 assessments, and no want to embellish check strategies with attributes. It has some easy assertions, however you need to actually simply use FluentAssertions, or Shouldly, or one other assertion framework. You may construct your personal 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 end result with a set of expectations routinely created by means of code.

Reqnroll
Reqnroll is an open-source .NET check automation instrument to apply Conduct Pushed Improvement (BDD). Reqnroll is a .NET port of Cucumber and it’s primarily based on the SpecFlow framework and code base. You will discover extra details about the objective of the Reqnroll undertaking and the motivations to create it on the Reqnroll web site.
Reqnroll allows writing executable specs for BDD utilizing Gherkin, the widely-accepted characteristic file specification format. With that you would be able to outline the necessities utilizing Given-When-Then model eventualities and switch them to automated assessments with a view 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 eventualities, Reqnroll can use MsTest, NUnit or xUnit. On Reqnroll tasks you possibly can work utilizing Visible Studio 2022, Visible Studio Core and Rider, however you can too use Reqnroll with none IDE.
