Hi

We use Specflow 3 with mstest in a .NET Framework 4.7.2 project for our CI tests. Im' trying to user Wiremock.net version 1.4.43 to mock restApi Calls. So far, only Wiremock started in a separate console application is working. If i copy the same startup code directly in my stepdefinition or specflowhook, result in a timeout...

_wmserver = WireMockServer.Start(new WireMock.Settings.WireMockServerSettings
{
	ReadStaticMappings = true,
	AllowPartialMapping = true,
	HandleRequestsSynchronously = true,
	UseSSL = false,
});

_wmserver.Url is then injected in my configuration, and the specflow is executed... i get the following error:

System.Web.HttpException: 0 : The operation has timed out

I've seen some post discussing about this but no solution provided fixed mine. adding HandleRequestsSynchronously = was one of them.

Any advice?

Thanks

Hi,
Trying to create a working example starting a new specflow project in Visual studio 2019 kinda clean specflow, i cannot reproduce the problem.

We are working with legacy specflow project file on my team(created years ago, maybe with VS 2012), and cannot pinpoint what exactly is causing this...

Hi again!

Just found out we were missing 4 bindings redirects.

But somehow, that was causing the hang instead of throwing exception. I found out debuging and activating full Exception Break Logging on CLR Exception.

"System.Numerics.Vectors"
"System.Buffers"
"System.Runtime.CompilerServices.Unsafe"
"System.Threading.Tasks.Extensions"

hope this is helpful to someone one day...
