#### Documentation

# Purpose
# -------
#
# To run all tests possible or available on the platform.
#
# Notes for users
# ---------------
#
# Warning: the test is destructive. It includes various build modes and
# configurations, and can and will arbitrarily change the current CMake
# configuration. The following files must be committed into git:
#    * include/mbedtls/config.h
#    * Makefile, library/Makefile, programs/Makefile, tests/Makefile
# After running this script, the CMake cache will be lost and CMake
# will no longer be initialised.
#
# The script assumes the presence of a number of tools:
#   * Basic Unix tools (Windows users note: a Unix-style find must be before
#     the Windows find in the PATH)
#   * Perl
#   * GNU Make
#   * CMake
#   * GCC and Clang (recent enough for using ASan with gcc and MemSan with clang, or valgrind)
#   * G++
#   * arm-gcc and mingw-gcc
#   * ArmCC 5 and ArmCC 6, unless invoked with --no-armcc
#   * OpenSSL and GnuTLS command line tools, recent enough for the
#     interoperability tests. If they don't support SSLv3 then a legacy
#     version of these tools must be present as well (search for LEGACY
#     below).
# See the invocation of check_tools below for details.
#
# This script must be invoked from the toplevel directory of a git
# working copy of Mbed TLS.
#
# Note that the output is not saved. You may want to run
#   script -c tests/scripts/all.sh
# or
#   tests/scripts/all.sh >all.log 2>&1
#
# Notes for maintainers
# ---------------------
#
# The bulk of the code is organized into functions that follow one of the
# following naming conventions:
#  * pre_XXX: things to do before running the tests, in order.
#  * component_XXX: independent components. They can be run in any order.
#      * component_check_XXX: quick tests that aren't worth parallelizing
#      * component_build_XXX: build things but don't run them
#      * component_test_XXX: build and test
#  * support_XXX: if support_XXX exists and returns false then
#    component_XXX is not run by default.
#  * post_XXX: things to do after running the tests.
#  * other: miscellaneous support functions.
#
# The tests are roughly in order from fastest to slowest. This doesn't
# have to be exact, but in general you should add slower tests towards
# the end and fast checks near the beginning.
#
# Sanity checks have the following form:
#   1. msg "short description of what is about to be done"
#   2. run sanity check (failure stops the script)
#
# Build or build-and-test steps have the following form:
#   1. msg "short description of what is about to be done"
#   2. cleanup
#   3. preparation (config.pl, cmake, ...) (failure stops the script)
#   4. make
#   5. Run tests if relevant. All tests must be prefixed with
#      if_build_successful for the sake of --keep-going.

Usage: $0 [OPTION]... [COMPONENT]...
Run mbedtls release validation tests.
By default, run all tests. With one or more COMPONENT, run only those.

Special options:
  -h|--help             Print this help and exit.
  --list-all-components List all available test components and exit.
  --list-components     List components supported on this platform and exit.

General options:
  -f|--force            Force the tests to overwrite any modified files.
  -k|--keep-going       Run all tests and report errors at the end.
  -m|--memory           Additional optional memory tests.
     --armcc            Run ARM Compiler builds (on by default).
     --except           If some components are passed on the command line,
                        run all the tests except for these components. In
                        this mode, you can pass shell wildcard patterns as
                        component names, e.g. "$0 --except 'test_*'" to
                        exclude all components that run tests.
     --no-armcc         Skip ARM Compiler builds.
     --no-force         Refuse to overwrite modified files (default).
     --no-keep-going    Stop at the first error (default).
     --no-memory        No additional memory tests (default).
     --out-of-source-dir=<path>  Directory used for CMake out-of-source build tests.
     --random-seed      Use a random seed value for randomized tests (default).
  -r|--release-test     Run this script in release mode. This fixes the seed value to 1.
  -s|--seed             Integer seed value to use for this test run.

Tool path options:
     --armc5-bin-dir=<ARMC5_bin_dir_path>       ARM Compiler 5 bin directory.
     --armc6-bin-dir=<ARMC6_bin_dir_path>       ARM Compiler 6 bin directory.
     --gnutls-cli=<GnuTLS_cli_path>             GnuTLS client executable to use for most tests.
     --gnutls-serv=<GnuTLS_serv_path>           GnuTLS server executable to use for most tests.
     --gnutls-legacy-cli=<GnuTLS_cli_path>      GnuTLS client executable to use for legacy tests.
     --gnutls-legacy-serv=<GnuTLS_serv_path>    GnuTLS server executable to use for legacy tests.
     --openssl=<OpenSSL_path>                   OpenSSL executable to use for most tests.
     --openssl-legacy=<OpenSSL_path>            OpenSSL executable to use for legacy tests e.g. SSLv3.
     --openssl-next=<OpenSSL_path>              OpenSSL executable to use for recent things like ARIA
