Hi! Glad to see the project is thriving! I noticed a little side-effect though :)

Describe the bug

Unmatched requests are no longer saved

Expected behavior:

They should be

Test to reproduce

  • Set this option to true
  • Try sending the wrong request
  • It will be present in logs, but no file is created and LocalFileSystemHandler.WriteUnmatchedRequest() is not even called

Other related info

This doesn't work on the latest version 1.5.35, but I see many changes published on Aug 3. I tried to downgrade to version 1.5.32 and it works in 1.5.32, but doesn't work in 1.5.34 and 1.5.35.

The function WriteUnmatchedRequest is not even called in the latest versions. I tested this using my file handler:

public class MyLocalFileSystemHandler : LocalFileSystemHandler
{
    private readonly string _dataFolder;
    public MyLocalFileSystemHandler(string dataFolder) => _dataFolder = dataFolder;

    public override string GetMappingFolder() => _dataFolder;
    public override string GetUnmatchedRequestsFolder() => _dataFolder;

    public override void WriteUnmatchedRequest(string filename, string text)
    {
        string unmatchedRequestsFolder = GetUnmatchedRequestsFolder(); // We never stop at the breakpoint here
        if (!FolderExists(unmatchedRequestsFolder))
            CreateFolder(unmatchedRequestsFolder);
        File.WriteAllText(Path.Combine(unmatchedRequestsFolder, filename), text);
    }
}

If I downgrade to 1.5.32 the breakpoint does hit and the file is successfully saved.

Maybe something has changed in the way the condition is calculated here 59aab9e1c3/src/WireMock.Net/Owin/WireMockMiddleware.cs (L190-L191)

@LevYas
I have added an extra unit test and changed the code you suggested.

Can you please test preview version 1.5.35-ci-17786 ?

Thank you for such a quick reaction!

I installed this version via MyGet feed, but the error is still reproducible. I'm not sure that the problem is exactly in the line I mentioned - I meant that the match structure/logic might be changed, but I'm not sure.

Does your unit test pass without the modification to the condition line? I don't see the logic changes, for me, it does the same.

Is it possible that an exception is thrown in the request logging? Json serialization in this method can throw.

Not in this line, but if I start debugging with "just my code" disabled, I get JSON serialization error:

Newtonsoft.Json.JsonReaderException: 'Unexpected character encountered while parsing value: P. Path '', line 0, position 0.'

In that moment, current string in the json parser is

"POST https://uat.portal.suppliesnet.net/invoices/invoices.asmx\r\nContent-Type: text/xml; charset=utf-8\r\n\r\n<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">\r\n \r\n <GetInvoices xmlns="http://portal.suppliesnet.net">\r\n \r\n <dmi:InvoiceRequest xmlns:dmi="http://portal.suppliesnet.net">\r\n dmi:RequesterISA1065133D2D</dmi:RequesterISA>\r\n dmi:InvoiceCreateDate2023-05-25</dmi:InvoiceCreateDate>\r\n </dmi:InvoiceRequest>\r\n \r\n \r\n \r\n\r\n\r\n\r\n\r\n

That is why we never reach the WriteUnmatchedRequest.

The exceptions itself is quite strange:

Newtonsoft.Json.JsonSerializationException
Error getting value from 'ReadTimeout' on 'MimeKit.IO.MemoryBlockStream'. Timeouts are not supported on this stream.

Probably that happened when the serializer tried to serialize BodyAsMimeMessage.

Thank you for the analysis.

MimeMessage support is fairly new. However you are not using any Multiparty Mine, correct?

I'll try to use your mapping and debug the code.

Btw thank you for the sponsoring.

UR welcome, happy to help.
I don't use anything like that. My main use case is to write some request-response pairs in proxy mode, disable proxy mode, and use the recordings both as snapshot tests for request factories and tests for response handlers and many other parts of the code that require interaction with third-party API. I work with JSON and XML (SOAP) APIs. Thanks to the speed and convenience of WMN, I don't use mocked unit tests for API-related code.

My pleasure!

@LevYas commented on GitHub (Sep 20, 2023): UR welcome, happy to help. I don't use anything like that. My main use case is to write some request-response pairs in proxy mode, disable proxy mode, and use the recordings both as snapshot tests for request factories and tests for response handlers and many other parts of the code that require interaction with third-party API. I work with JSON and XML (SOAP) APIs. Thanks to the speed and convenience of WMN, I don't use mocked unit tests for API-related code. My pleasure!
