How to do an integration test on my Asp.Net core web api endpoint where I upload a file?

-1

I am writing an integration test that tests the upload of a file to one of my endpoints and checks if the request result is correct!

I am using IFormFile in my controller to receive the request, but I am getting a 400 Bad request because apparently my file is null.

How do I allow an integration test to send a file to my endpoint? I found this post but that only talks about mocking IFormFile, not an integration test.

My controller:

[HttpPost]

public async Task<IActionResult> AddFile(IFormFile file)

{

   if (file== null)

   {

       return StatusCode(400, "A file must be supplied");

   }



   // ... code that does stuff with the file..



   return CreatedAtAction("downloadFile", new { id = MADE_UP_ID }, { MADE_UP_ID };

}

My integration test:

public class IntegrationTest:

    IClassFixture<CustomWebApplicationFactory<Startup>>

{

    private readonly CustomWebApplicationFactory<Startup> _factory;



    public IntegrationTest(CustomWebApplicationFactory<Startup> factory)

    {

        _factory = factory;

    }



    [Fact]

    public async Task UploadFileTest()

    {

        // Arrange

        var expectedContent = "1";

        var expectedContentType = "application/json; charset=utf-8";



        var url = "api/bijlages";

        var client = _factory.CreateClient();



        // Act

        var file = System.IO.File.OpenRead(@"C:file.pdf");

        HttpContent fileStreamContent = new StreamContent(file);



        var formData = new MultipartFormDataContent

        {

            { fileStreamContent, "file.pdf", "file.pdf" }

        };



        var response = await client.PostAsync(url, formData);



        fileStreamContent.Dispose();

        formData.Dispose();



        response.EnsureSuccessStatusCode();



        var responseString = await response.Content.ReadAsStringAsync();



        // Assert

        Assert.NotEmpty(responseString);

        Assert.Equal(expectedContent, responseString);

        Assert.Equal(expectedContentType, response.Content.Headers.ContentType.ToString());

    }

I hope you guys can help me (and possibly others!) out here!

can you use a tool like Fiddler and check what is actually the being posted?

Your code looks correct except the key in MultipartFormDataContent should be file & not file.pdf

Change the formdata to { fileStreamContent, "file", "file.pdf" }
