You could use this syntax here for creating the HttpResponseException:

var httpEx = new HttpResponseException(message)
{
    Response = response,
    Status = ...
    Headers = ...
};

Or you could make the constructor take all property values and make the properties read only.

Will change constructor

httpEx.Response = response;
ErrorRecord er = new ErrorRecord(httpEx, "WebCmdletWebResponseException", ErrorCategory.InvalidOperation, request);
er.ErrorDetails = new ErrorDetails(message);
ThrowTerminatingError(er);

The message for ErrorDetails should be the content of the response (after using regex replace to remove tags). This was what #3089 tried to fix, and the corresponding code in full powershell is here

Should we test for Exception.Headers and Exception.Status too?

Those are getting removed

Minor comment: this might fail if we are going to run this test on a localized machine.

@daxian-dbw Is a match good enough for the part returned from the server?

Yes, I think so, $result.Error.Exception.Message | Should BeLike * 418 (I'm a teapot) should be good, since they are returned from the Http service, not affected by PS localization.

$result.Error.FullyQualifiedErrorId | Should Be "WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand"
