#### 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)
#   * 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 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.

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).
     --no-armcc         Skip ARM Compiler builds.

     --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.

# Test Suites to be executed

# The test ordering tries to optimize for the following criteria:
# 1. Catch possible problems early, by running first tests that run quickly
#    and/or are more likely to fail than others (eg I use Clang most of the
#    time, so start with a GCC build).
# 2. Minimize total running time, by avoiding useless rebuilds
#
