[WebApplicationFactory] UseKestrel with SSL feedback #63012

First of all, thank you for adding UseKestrel I am happy to be able to write browser-based integration tests now.
Getting SSL working was a bit tricky so I wanted to give feedback. For context I am using SSL certificates provided by dotnet dev-certs, and Selenium ChromeDriver as well as the HttpClient returned by CreateClient. I was only interested in using SSL, but might need both SSL and non-SSL connections in the future.
Adding the following to the override of WebApplicationFactory worked to get SSL mostly working:
protected override void ConfigureWebHost(IWebHostBuilder builder)
{
builder.ConfigureKestrel(options =>
{
options.Listen(
IPAddress.Loopback,
ConfiguredPort,
listenOptions => listenOptions.UseHttps()
);
});
...
I use a predetermined "ConfiguredPort" because I need to set a configure value with the applications root url before starting the server.
The problem is HttpClient returned by CreateClient doesn't work:
- it is using the http schema, not https.
- it is using an IP address, and my dev-certs are for localhost
I worked around this with:
HttpClient CreateClient()
{
var result = serverFactory.CreateClient();
var uriBuilder = new UriBuilder(result.BaseAddress!);
uriBuilder.Host = "localhost";
uriBuilder.Scheme = "https";
result.BaseAddress = uriBuilder.Uri;
return result;
}
It works, but could be easier or at least have some documentation on how to proceed with SSL.
Last, its minor, but it would be nice to document when to call UseKestrel(). I initially tried it from my derived classes constructor, that didn't work, calling it from an override of InitializeAsync did work.
