# HDF5 CMake Testing and Dashboard Configuration
# -----------------------------------------------------------------------------
# This CMake module configures the testing and dashboard infrastructure for HDF5.
# It sets up test timeouts, test options, and enables/disables various test suites
# (API, VFD, VOL, serial, parallel, Fortran, C++, Java, tools, examples, SWMR, etc.).
# It also configures CTest integration, test express levels, and test directories.
#
# Key Features:
# - Configures DART/CTest timeouts and test express levels.
# - Provides options to enable/disable specific test suites and features.
# - Supports advanced test options (e.g., API async, driver, VFD lists, passthrough VOL).
# - Integrates with CTest and dashboard tools for automated testing.
# - Handles test directory setup for serial, parallel, and API tests.
#
# Usage:
#   HDF5 includes this file from the main CMakeLists.txt to enable and configure
#   HDF5 testing, if testing is enabled (BUILD_TESTING). Adjust options as needed
#   for your build and test requirements.
#
# See comments throughout for details on each option and logic branch.
