# Purpose
|
|
#
|
|
# The purpose of this test script is to validate that the library works
|
|
# with any combination of elliptic curves. To this effect, build the library
|
|
# and run the test suite with each tested combination of elliptic curves.
|
|
#
|
|
# Testing all 2^n combinations would be too much, so we only test 2*n:
|
|
#
|
|
# 1. Test with a single curve, for each curve. This validates that the
|
|
# library works with any curve, and in particular that curve-specific
|
|
# code is guarded by the proper preprocessor conditionals.
|
|
# 2. Test with all curves except one, for each curve. This validates that
|
|
# the test cases have correct dependencies. Testing with a single curve
|
|
# doesn't validate this for tests that require more than one curve.
|
|
|
|
# Usage: tests/scripts/curves.pl
|
|
#
|
|
# This script should be executed from the root of the project directory.
|
|
#
|
|
# Only curves that are enabled in config.h will be tested.
|
|
#
|
|
# For best effect, run either with cmake disabled, or cmake enabled in a mode
|
|
# that includes -Werror.
