+# AGENTS.md
+
+This file provides guidance to agents when working with code in this repository.
+
+## Project Overview
+Apache HTTP Server test suite using Perl-based Apache::Test framework. Tests Apache 1.3.x through trunk with custom C modules and Perl test scripts.
+
+## Build & Test Commands
+
+**Setup (required once):**
+```bash
+perl Makefile.PL -apxs /path/to/apache/bin/apxs
+```
+
+**Run all tests:**
+```bash
+t/TEST
+```
+
+**Run specific test file:**
+```bash
+t/TEST t/apache/byterange3.t
+```
+
+**Run tests in directory:**
+```bash
+t/TEST t/php
+```
+
+**Start/stop test server manually:**
+```bash
+t/TEST -start
+t/TEST -stop
+```
+
+**Clean generated files (required after Apache config changes):**
+```bash
+t/TEST -clean
+```
+
+**Run under debugger:**
+```bash
+t/TEST -d gdb
+```
+
+**Smoke testing (repeat N times):**
+```bash
+t/SMOKE -times=5 -verbose t/modules/rewrite.t
+```
+
+## Critical Non-Obvious Patterns
+
+1. **C modules embed their own config**: C modules in `c-modules/*/mod_*.c` have Apache config embedded at the top within `#if CONFIG_FOR_HTTPD_TEST` blocks. This config is auto-extracted during test setup.
+
+2. **Test harness generates config files**: `t/conf/httpd.conf` and `t/conf/extra.conf` are GENERATED from `.in` templates. Never edit the generated files directly - edit the `.in` files and run `t/TEST -clean`.
+
+3. **Custom Makefile.PL arguments**: This project extends Apache::TestMM with custom args like `limitrequestline` and `limitrequestlinex2` (see Makefile.PL lines 30-43). These are NOT standard Apache::Test options.
+
+4. **IPv4/6 confusion causes hangs**: If `t/TEST -start` hangs at "waiting for server to warm up" but port 8529 is reachable, comment out `::1` in `/etc/hosts`. The test server may listen on `0.0.0.0` only.
+
+5. **SSL cert expiration**: If SSL tests fail, run `t/TEST -clean` to regenerate expired certificates. Remove `t/conf/ssl/ca` before cleaning if cert errors persist.
+
+6. **Test file location matters**: Some tests modify DocumentRoot or create files in `t/htdocs/`. These tests cannot run against remote servers.
+
+7. **Module detection via need_* functions**: Tests use `need_module`, `need_min_apache_version`, etc. from Apache::Test to skip when requirements aren't met. Check test file headers for these.
+
+8. **Perl 5.28 on macOS homebrew hangs**: Use `/usr/bin/perl Makefile.PL` instead to avoid test suite hangs (see README line 195).
+
+## Code Style
+
+- **Strict mode**: ALL test files use `use strict; use warnings FATAL => 'all';`
+- **Apache version conditionals**: Use `<IfDefine APACHE2>` in config, `need_min_apache_version()` in tests
+- **Module conditionals**: Use `<IfModule @PHP_MODULE@>` syntax with @ placeholders in `.in` files
+- **C module style**: Use `#ifdef APACHE1` / `#else` for version-specific code in C modules
+- **debugging**: use `t_debug()` to add debug logging to assist in debugging with `t/TEST -v`.
+- **assert style** Avoid bare `ok` checks and instead use `ok t_cmp(received, expected, comment)` so failures can be diagnosed quickly.
+- **test style** when a number of relatedtests are needed, try to factor out inputs and validation into arrays or hashes leaving the body of 
+  test to iteration over this data
+
+## Test Framework Details
+
+- Framework: Apache::Test (bundled in `Apache-Test/`)
+- Test format: Perl `.t` files using `Test` module (not Test::More by default)
+- Default port: 8529 (configurable via `-port`)
+- Test server root: `t/` directory
+- Generated configs: `t/conf/`
+- Logs: `t/logs/`
