Testing

Flo uses NUnit for backend testing and Jasmine/Karma for frontend testing, with automated coverage reporting via GitHub Actions.

Backend Testing (NUnit + Moq)

Quick Start

# Run all tests
dotnet test Flo.BE.Tests

# Run with coverage report
./run-coverage.sh --open

Test Pattern

[TestFixture]
public class BookingServiceTests
{
    private Mock<IBookingRepository> _mockRepo;
    private BookingService _service;

    [SetUp]
    public void SetUp()
    {
        _mockRepo = new Mock<IBookingRepository>();
        _service = new BookingService(_mockRepo.Object);
    }

    [Test]
    public async Task CreateBooking_ValidRequest_ReturnsSuccess()
    {
        // Arrange
        var dto = new CreateBookingDto(1, DateTime.Now, "Notes");

        // Act
        var result = await _service.CreateAsync(dto);

        // Assert
        Assert.That(result, Is.Not.Null);
        _mockRepo.Verify(x => x.AddAsync(It.IsAny<Booking>()), Times.Once);
    }

    [TestCase("valid@email.com", true)]
    [TestCase("", false)]
    public void ValidateEmail_ReturnsExpected(string email, bool expected)
    {
        var result = _service.IsValidEmail(email);
        Assert.That(result, Is.EqualTo(expected));
    }
}

Rules

• Use NUnit ([Test], [SetUp], [TearDown], Assert.That()) — never xUnit
• Use Moq for mocking dependencies
• All backend services require unit tests
• Follow Arrange-Act-Assert pattern

Frontend Testing

cd Flo.FE
ng test

Uses Jasmine/Karma with Angular TestBed. All components use OnPush change detection, which must be accounted for in tests.

CI/CD

Code Coverage

GitHub Actions runs coverage every 15 days:

• Executes dotnet test with coverage collection
• Publishes report to Codecov
• Badge displayed in README

i18n Check

CI validates that it.json and en.json have matching translation keys. Fails if any key is missing from either file.

Docker Build

On push to master or develop:

• Builds Docker image
• Publishes to GitHub Container Registry
• Tags: latest (master), develop-latest (develop), <branch>-<commit> (all)
