+# CMCONF Test Suite
+
+Comprehensive test suite for the CMCONF (CMake Configuration Framework) component library.
+
+## Test Modules
+
+Currently tested functionality
+
+- **`CMCONF_SET`** - Configuration variable setting
+- **`CMCONF_GET`** - Configuration variable retrieval
+- **`CMCONF_INIT_SYSTEM`** - System name configuration
+- **`INSTALL Feature`** - Configuration installation
+- **`UNINSTALL Feature`** - Configuration uninstallation
+
+Not covered functionality
+
+- Edge cases for Windows OS regard of `reg` command behaviour.
+  It is expected that this command is available on Windows be default.
+  If not, not only CMake but also Windows itself is broken.  
+
+### Test Structure
+
+Tests are organized into subdirectories within `test_cases`, separated into:
+
+- **`pass/`** - Tests that verify correct functionality and expected behavior
+- **`fail/`** - Tests that verify proper error handling and validation
+
+Each test case directory contains a `CMakeLists.txt` file that tests specific functionality.
+
+Configuration templates and test resources are placed in the `config_templates` directory.
+
+## Test Framework
+
+- `TEST.cmake` - Common test macros. It is reused from CMLIB.
+- `cache_var.cmake` - Macros to force set and restore cache variables. It is reused from CMLIB.
+- `test_cmconf_helpers.cmake` - CMCONF-specific test helper functions and macros
+
+### Test Resource Creation and Maintenance
+
+When external resources are needed to test functionality:
+
+- Configuration templates are provided in the `config_templates` directory
+- Test configurations are created from predefined templates
+- There are no external dependencies to download or install
+- There shall be no dynamic creation of test resources during a test run (exceptions can apply if reasoned)
+
+## Running Tests
+
+**All tests are designed to be run from a clean source tree.**
+
+CMCONF is consistent and functional only when all tests pass.
+
+Any test failure indicates CMCONF is not working as expected, even if the failure seems unrelated to required functionality. Complete system consistency is essential for reliable operation.
+
+### Run All Tests
+
+Tests shall be run in Project and Script mode.
+
+```bash
+# Project mode
+git clean -xfd .
+cmake .
+
+# Script mode
+git clean -xfd .
+cmake -P ./test/CMakeLists.txt
+```
+
+### Clean Up
+
+```bash
+git clean -xfd .
+```
+
+## Platform Considerations
+
+Tests are designed to run on Linux-based systems as the main development platform. Platform-specific behavior is tested where applicable, particularly for:
+
+- Unix home directory handling
+- System-specific configuration paths (windows vs unix)
+- Platform-specific variable behaviors
