LoFuUnit 2.0.0

LoFuUnit

Use the traditional Unit Testing Frameworks for BDD.

Use local functions to structure tests with patterns like:

• Arrange / Act / Assert
• Given / When / Then
• Context / Specification

LoFuUnit and related packages makes it convenient for developers to write tests with collaboration & communication in mind.

Tests ✔️

An example of a test with LoFuUnit, NUnit and FluentAssertions:

using FluentAssertions;
using LoFuUnit;
using NUnit.Framework;

namespace LoFuUnitDocs
{
    public class AuthenticationTests : LoFuTest
    {
        SecurityService Subject;
        UserToken Token;

        [Test]
        public void Authenticate_admin_users()
        {
            Subject = new SecurityService();

            Assert();

            void when_authenticating_an_admin_user() =>
                Token = Subject.Authenticate("username", "password");

            void should_indicate_the_user_s_role() =>
                Token.Role.Should().Be(Roles.Admin);

            void should_have_a_unique_session_id() =>
                Token.SessionId.Should().NotBeNull();
        }
    }
}

Output:

Authenticate admin users
    when authenticating an admin user
    should indicate the user's role
    should have a unique session id

Test methods can contain local functions that are invoked implicitly. These test functions can perform the arrange, act or assert steps of the test.

The LoFuTest base class provides two important methods for test fixtures. The Assert and AssertAsync methods invokes the test functions in the containing test method. The invocations will occur in the order that the test functions are declared. If a test function fails, the test method fails directly. Any subsequent test functions in the test method will not be invoked. Make sure that all test methods actually invoke Assert or AssertAsync.

Test fixtures that does not inherit the LoFuTest base class can invoke the extension methods:

• this.Assert();
• await this.AssertAsync();
