xApi - Single line to test your api !

Easy way to build integration test using xUnit & WebApplicationFactory

Basic Usage

 _fixture.Api.Rout<SampleControllerTest>(nameof(SampleControllerTest.GetAll))
    .FromQuery(nameof(name),name)
    .Send()
    .AssertSuccessStatusCode();

• OR :

 _fixture.Api.Rout(HttpMethod.Get, "api/something/getbyid")
    .FromRoute(nameof(id),id)
    .Send()
    .AssertSuccessStatusCode();

Setup

create Fixture class to use it in all tests

public class IntegrationTestFixture : IntegrationTest<Startup>
{
    public IntegrationTestFixture()
    {
        Configure(webApplicationBuilder: builder => builder.UseEnvironment(Environments.Development),
            clientBuilder: options => options.AllowAutoRedirect = false);
    }
}

Example how to use IntegrationTestFixture for SampleControllerTest api testing

public class SampleControllerTest : IClassFixture<IntegrationTestFixture>
{
    private readonly IntegrationTestFixture _fixture;


    public SampleControllerTest(IntegrationTestFixture fixture, ITestOutputHelper output)
    {
        _fixture = fixture;
        _fixture.SetApiOutput(output); // to dispaly some info while sending apis (url , request , response , status code ..)
    }

    [Fact]
    public Task AnyApiTest()
    {
        // logic
    }
}

How To Send Query / Routes

var id = Guid.NewGuid();
_fixture.Api.Rout<SampleControllerTest>(nameof(SampleControllerTest.Get))
    .FromQuery(nameof(id),id) // key & value
    .FromQuery(new // anonymos object
    {
        id,
    })
    .FromQuery(new AnyDto() // object like dto, mv, ..etc
    {
        Id = id,
    })
    

same for Routes just use FromRoute() instead of FromQuery().

How To Send Json / FormData

_fixture.Api.Rout<SampleControllerTest>(nameof(SampleControllerTest.Add))
    .FromBody(new AddRequstClass // for Json body request
    {
        Id = Guid.NewGuid(),
        Email = "test@xapi.com",
    })
    .FromForm(new AddRequstClass // for Multipart Form Data body request
    {
        Name = "Simple Test",
        ImageFile = _fixture.FormFile("AssetsFolder/test.png")
    })    

Assert Status Code

You can use this methods :

• AssertSuccessStatusCodeAsync() / AssertSuccessStatusCode() when its range 200-299.
• AssertNotSuccessStatusCodeAsync() / AssertNotSuccessStatusCode() when its otherwise range 200-299.
• AssertStatusCodeEqualsAsync(HttpStatusCode.OK) / AssertStatusCodeEquals(HttpStatusCode.OK)
• AssertStatusCodeNotEqualsAsync(HttpStatusCode.Conflict) / AssertStatusCodeNotEquals(HttpStatusCode.Conflict)

Working With Files

You have FormFile() method in IntegrationTest<TStartup> to help you to send files as IFormFile with 3 overloads :

public IFormFile FormFile(string path, string? contentType = null)

 public IFormFile FormFile(Stream stream, string fileName, string? contentType = null)

public IFormFile FormFile(byte[] bytes, string fileName, string? contentType = null)

Note: the optional contentType parameter throw null exception if TryGetContentType() returns false, means contentType is unknown.

PS: can send empty Files with FakeFormFile() method.
