Feature: HTTP Server Module

As a developer using the Modular framework

I want to use the httpserver module for serving HTTP requests

So that I can build web applications with reliable HTTP server functionality

Background:

Given I have a modular application with httpserver module configured

Scenario: HTTP server module initialization

When the httpserver module is initialized

Then the HTTP server service should be available

And the server should be configured with default settings

Scenario: HTTP server with basic configuration

Given I have an HTTP server configuration

When the HTTP server is started

Then the server should listen on the configured address

And the server should accept HTTP requests

Scenario: HTTPS server with TLS configuration

Given I have an HTTPS server configuration with TLS enabled

When the HTTPS server is started

Then the server should listen on the configured TLS port

And the server should accept HTTPS requests

Scenario: Server timeout configuration

Given I have an HTTP server with custom timeout settings

When the server processes requests

Then the read timeout should be respected

And the write timeout should be respected

And the idle timeout should be respected

Scenario: Graceful server shutdown

Given I have a running HTTP server

When the server shutdown is initiated

Then the server should stop accepting new connections

And existing connections should be allowed to complete

And the shutdown should complete within the timeout

Scenario: Health check endpoint

Given I have an HTTP server with health checks enabled

When I request the health check endpoint

Then the health check should return server status

And the response should indicate server health

Scenario: Handler registration

Given I have an HTTP server service available

When I register custom handlers with the server

Then the handlers should be available for requests

And the server should route requests to the correct handlers

Scenario: Middleware integration

Given I have an HTTP server with middleware configured

When requests are processed through the server

Then the middleware should be applied to requests

And the middleware chain should execute in order

Scenario: TLS certificate auto-generation

Given I have a TLS configuration without certificate files

When the HTTPS server is started with auto-generation

Then the server should generate self-signed certificates

And the server should use the generated certificates

Scenario: Server error handling

Given I have an HTTP server running

When an error occurs during request processing

Then the server should handle errors gracefully

And appropriate error responses should be returned

Scenario: Server metrics and monitoring

Given I have an HTTP server with monitoring enabled

When the server processes requests

Then server metrics should be collected

And the metrics should include request counts and response times

Scenario: Emit events during httpserver lifecycle

Given I have an httpserver with event observation enabled

When the httpserver module starts

Then a server started event should be emitted

And a config loaded event should be emitted

And the events should contain server configuration details

Scenario: Emit events during TLS configuration

Given I have an httpserver with TLS and event observation enabled

When the TLS server module starts

Then a TLS enabled event should be emitted

And a TLS configured event should be emitted

And the events should contain TLS configuration details

Scenario: Emit events during request handling

Given I have an httpserver with event observation enabled

When the httpserver processes a request

Then a request received event should be emitted

And a request handled event should be emitted

And the events should contain request details

Scenario: All registered httpserver events are emitted

Given I have an httpserver with TLS and event observation enabled

When the httpserver processes a request

And the server shutdown is initiated

Then a server started event should be emitted

And a config loaded event should be emitted

And a TLS enabled event should be emitted

And a TLS configured event should be emitted

And a request received event should be emitted

And a request handled event should be emitted

And all registered events should be emitted during testing
