BetterSpecs

xSpec "is a great tool in the behavior-driven development (BDD) process of writing human readable specifications that direct and validate the development of your application" (betterspecs.org).

BetterSpecs is the simple way to bring the power of spec to your tests. Based in xSpec (Like RSpec, and Jasmine) tools, BetterSpecs, improves tests experience on xUnit tools.

📦 install package

To install Betterspec in your MSTest project use this command:

PM> Install-Package Betterspecs.Core

📦 using betterspecs

using BetterSpecs;

[TestClass]
public class SpecContextTests : Spec
{
  ...
}

describe

[TestMethod]
public void describe_speccontext_while_using_it()
{
    describe["when use SpecContext class"] = () =>
    {
        it["works very well"] = () => Assert.IsTrue(true);
    };
}

mixin contexts

[TestMethod]
public void describe_speccontext_while_using_it()
{
    context["when use SpecContext class"] = () =>
    {
        context["with two context"] = () =>
        {
            it["works very well"] = () => Assert.IsTrue(true);
        };
    };
}

using let

defer the instance creation

[Test]
public void describe_register_user()
{
    context["when create a user"] = () =>
    {
        User user = null;
        let.Add("user", () => 
        { 
          user = new User("teste@teste.com");
          return user;
        });
        
        it["is null"] = () => Assert.Null(user);
        it["is not null"] = () => Assert.AreEqual(user, let["user"]);
    };
}

output spec

When finished run tests, the output will be like this:

when use SpecContext class
with other internal context
    It works very well
