Тестирование API загруженного файла с использованием xunit ⇐ C#

[Anonymous]

I have a class as follows:

Код: Выделить всё

public class FileUploadRequest
{
public IFormFile FileUploaded { get; set; }
}

This is my Controller:

Код: Выделить всё

public class MyController : ControllerBase
{
private readonly IMyService _service;

public MyController(IMyService service)
{
_service = service;
}

/// 
/// Send a csv file to create a new report.
/// 
[HttpPost]
public async Task CreateReport([FromForm] FileUploadRequest inputCsvFile)
{
IdResponse response = await _service.CreateReport(inputCsvFile);
return Created("", response);
}
}

This is my Service:

Код: Выделить всё

public class MyService : IMyService
{
private readonly IMyRepository _repository;

private readonly IMapper _mapper;

public MyService(
IMyRepository repository,
IMapper mapper)
{
_repository = repository;
_mapper = mapper;
}
public async Task CreateReport(FileUploadRequest inputCsvFile)
{
if (inputCsvFile.FileUploaded == null)
{
throw new BusinessException(BusinessErrorCode.NO_FILE_UPLOADED);
}
if (inputCsvFile.FileUploaded.ContentType != "text/csv")
{
throw new BusinessException(BusinessErrorCode.INVALID_FILE_TYPE, inputCsvFile.FileUploaded.ContentType);
}
IEnumerable reportDetails = ParseDetailFromCsv(inputCsvFile.FileUploaded);
if(reportDetails == null || !reportDetails.Any())
{
throw new BusinessException(BusinessErrorCode.NO_VALID_DATA);
}
IEnumerable details = _mapper.Map(details);
string result = await _repository.CreateReport(inputCsvFile.FileUploaded, reportDetails);
IdResponse response = new()
{
Id = result
};
return response;
}
}

Currently, I want to test with a sample file saved in the Asset folder of the Test project using xunit. This is my test:

Код: Выделить всё

[Theory]
[InlineData("REPORT_DETAILS_TEST.csv")]
public async Task CreateReport_CreateSuccessfully(string fileName)
{
// Arrange
// Create a context with useInMemory option
using var context = new DataContext(TestHelper.CreateMockDbOptions());
var repository = new MyRepository(context);
var service = new MyService(repository, _mapper);
var controller = new MyController(service);

string exePath = Path.GetDirectoryName(Assembly.GetEntryAssembly()!.Location)!;
string filePath = exePath + $"/Assets/{fileName}";
var formFile = new FormFile(
new MemoryStream(),
0,
new FileInfo(filePath).Length,
"ReportTestFile",
Path.GetFileName(filePath)
);

var inputFile = new FileUploadRequest { FileUploaded = formFile };

// Act
var result = await controller.CreateReport(inputFile);

// Assert
Assert.NotNull(result);

}

However, I realized I couldn't create a FileUploadRequest object the same as when sending using the real API. (ContentType, ContentDisposition, Header fields are null) This causes validation at the service to fail. Is there a way to solve this problem?
