Devpro Withywoods - Shared .NET libraries

Whithywoods is a set of small independant .NET libraries (Standard/Core). The goal is to do better with less code and capitalize on best practices (#KISS #DRY).

All libraries are available on nuget.org. Feel free to report any issue or ask for a change. You can also contribute with Pull Requests on GitHub!

NB: The name Whithywoods comes from Robin Hobb's incredible writing.

Web / Web Testing library

tl;dr Use Selenium web driver inside ASP.NET Integration tests? Yes, that's possible with LocalServerFactory class!

public class SwaggerResourceTest : IClassFixture<LocalServerFactory<Startup>>, IDisposable
{
    [Fact]
    public void AspNetCoreApiSampleSwaggerResourceGet_ReturnsHttpOk()
    {
        // Arrange & Act
        _webDriver.Navigate().GoToUrl($"{_server.RootUri}/{_ResourceEndpoint}");

        // Assert
        _webDriver.FindElement(By.ClassName("title"), 360);
        _webDriver.Title.Should().Be("Swagger UI");
        _webDriver.FindElementByClassName("title").Text.Should().Contain("My API");
    }
}

Want to write easy API Rest tests? Sure, just use the TestRunner class!

[Fact]
public async Task AspNetCoreApiSampleTaskResourceFullCycle_IsOk()
{
    var initialTasks = await _restRunner.GetResources<TaskDto>(_client);
    initialTasks.Count.Should().Be(0);

    var created = await _restRunner.CreateResource<TaskDto>(_client);

    await _restRunner.GetResourceById(created.Id, _client, created);

    await _restRunner.UpdateResource(created.Id, created, _client);

    var existingTasks = await _restRunner.GetResources<TaskDto>(_client);
    existingTasks.Count.Should().Be(1);

    await _restRunner.DeleteResource(created.Id, _client);

    var expectedNotFound = new ProblemDetails
    {
        Title = "Not Found",
        Status = 404,
        Type = "https://tools.ietf.org/html/rfc7231#section-6.5.4"
    };
    await _restRunner.GetResourceById(created.Id, _client, expectedNotFound, HttpStatusCode.NotFound, config => config.Excluding(x => x.Extensions));

    var finalTasks = await _restRunner.GetResources<TaskDto>(_client);
    finalTasks.Count.Should().Be(0);
}
