selector creation and name retrieval with `sel_getName()`. | + +--- + +## System Tests + +| Test Name | Purpose | Description | +|-----------|---------|-------------| +| sys_00 | Memory System Functions | Tests `sys_malloc()`, `sys_free()`, `sys_memset()`, `sys_memcpy()`, `sys_memmove()`, `sys_memcmp()`. | +| sys_01 | Printf System Functions | Tests `sys_printf()`, `sys_sprintf()`, and `sys_vsprintf()` with 102 tests covering format specifiers, width modifiers, and buffer overflow. | +| sys_02 | Date and Time System Functions | Tests `sys_date_*` functions: current date/time acquisition, UTC/local time conversion, date/time component extraction and setting, nanosecond precision comparison, timezone handling, parameter validation, gmtime/timegm integration. | +| sys_03 | Thread System Functions | Tests `sys_thread_numcores()` with validation and boundary checks. | +| sys_04 | Random Number Generation | Tests `sys_random_uint32()` and `sys_random_uint64()` with distribution testing. | +| sys_05 | Hash Function Testing | Tests `sys_hash_*` functions with MD5/SHA-256 algorithms and test vectors. | +| sys_06 | Input/Output System Functions | Tests `sys_printf()` formatting with integers, characters, and strings. | +| sys_07 | Mutex Functions | Tests `sys_mutex_*` initialization, locking, unlocking, and error handling. | +| sys_08 | Condition Variable Functions | Tests `sys_cond_*` initialization, signaling, broadcast, and timedwait. | +| sys_09 | Thread Creation Functions | Tests `sys_thread_*` functions: numcores detection, thread creation/execution, core-specific creation, error handling, sleep edge cases. | +| sys_10 | Threading Stress Tests | High contention mutex, producer/consumer, race condition detection, extreme stress (21K ops), CPU affinity. | +| sys_11 | Waitgroup Synchronization | Basic/delayed coordination, result collection, high-load stress (5K ops), error handling. | +| sys_12 | Event Queue Operations | Basic ops, overflow/overwrite, threading, peek-before-acquire, shutdown, high volume (800 events), rapid shutdown, mixed operations. | +| sys_13 | Event Queue Cross-Core Communication | Tests event queue initialization, basic push/pop operations, multicore producer-consumer patterns, timeout behavior, and error handling with bidirectional communication between cores. | +| sys_14 | Dual-Core Event Queue with Timers | Tests dual-core event queue consumption with timer-driven event production, cross-core event mixing, high-load scenarios with atomic counters, and timer-based coordination. | +| sys_15 | Hash Table Operations | Tests comprehensive hash table functionality including basic operations (init, put, get by key/value), collision handling with linear probing, automatic chaining/growth, deletion operations, iteration, edge cases with replacement callbacks, and count/capacity tracking across chained tables. | +| sys_16 | Environment Information | Tests environment information functions including `sys_env_serial()`, `sys_env_name()`, and `sys_env_version()` with validation of non-null return values, non-empty strings, and consistency across multiple calls. | +| sys_17 | Atomic Operations | Tests `sys_atomic_*` API for initialization, get/set semantics, and atomic increment/decrement returning the post-operation value using a uint32_t counter. | + +--- + +## File System Tests + +| Test Name | Purpose | Description | +|-----------|---------|-------------| +| fs_01 | Volume Init Size | Creates a RAM volume with requested size and verifies actual capacity is >= requested; finalizes volume. | +| fs_02 | Directory Iteration Basics | Creates directories, iterates root, and validates iterator lifecycle and entry reporting. | +| fs_03 | File-Backed Volume + Dirs | Opens file-backed volume, creates directories, lists entries, and reports total/free/used sizes. | +| fs_04 | Dir Create/Delete Stress | Creates and removes many directories on a RAM volume; validates stat, entry counts, and free space deltas. | +| fs_05 | Basic File I/O | Creates a RAM volume, creates a file, writes known payload, seeks to start, reads back, verifies size and contents. | +| fs_06 | Append and Partial I/O | Verifies partial writes and reads across multiple calls, EOF behavior (read returns 0), and appending by reopening and seeking to end, with final content check. | +| fs_07 | Overwrite/Seek/Extend | Large writes across blocks, mid-file overwrite, invalid large seek rejection, seek-beyond-EOF then write to extend file and verify tail/size. | +| fs_08 | Boundary Interleaved I/O | Partial writes around block boundaries with overlapping regions and interleaved reads; validates overlap resolution and final size. | +| fs_09 | Rename and Move | Creates files then renames within a directory, moves across directories, and renames a directory containing a file; verifies content and stat results at each step. | diff --git a/test/objc/objc/runtime-objc.cmake
