LoFuUnit.AutoNSubstitute
1.1.1
Auto-mocked Unit Testing with Local Functions 🐯
Use the traditional Unit Testing Frameworks to write TDD or BDD tests:
✔️ Arrange / Act / Assert
✔️ Given / When / Then
✔️ Context / Specification
Use NSubstitute to:
✔️ Mock / Fake / Stub
See the version list below for details.

An example of a test with LoFuUnit.AutoNSubstitute
, LoFuUnit.NUnit and FluentAssertions:
using System;
using FluentAssertions;
using LoFuUnit.AutoNSubstitute;
using LoFuUnit.NUnit;
using NSubstitute;
using NUnit.Framework;
namespace LoFuUnitDocs
{
public class MoodTests : LoFuTest<MoodIdentifier>
{
string _mood;
[LoFu, Test]
public void Identify_mood_on_mondays()
{
void given_the_current_day_is_monday()
{
var monday = new DateTime(2011, 2, 14);
Use<ISystemClock>()
.CurrentTime
.Returns(monday);
}
void when_identifying_my_mood() =>
_mood = Subject.IdentifyMood();
void should_be_pretty_bad() =>
_mood.Should().Be("Pretty bad");
}
}
}
Output:
Identify mood on mondays
given the current day is monday
when identifying my mood
should be pretty bad
The LoFuTest<TSubject>
base class provides auto-mocking capabilities. The generic type parameter defines what kind of subject under test to create.
The Use<TDependency>
method creates a mock that the subject is dependent upon, and it can later be accessed via the The<TDependency>
method.
Use these methods to configure the behavior and verify the interaction with the mocks.
The Subject
property returns an auto-mocked instance of the subject under test.
