# This script runs tests before and after a PR and analyzes the results in
|
|
# order to highlight any difference in the set of tests skipped.
|
|
#
|
|
# It can be used to check the first testing criterion mentioned in strategy.md,
|
|
# end of section "Supporting builds with drivers without the software
|
|
# implementation", namely: the sets of tests skipped in the default config and
|
|
# the full config must be the same before and after the PR.
|
|
#
|
|
# USAGE:
|
|
# - First, commit any uncommited changes. (Also, see warning below.)
|
|
# - Then launch --> [SKIP_SSL_OPT=1] docs/architecture/psa-migration/outcome-analysis.sh
|
|
# - SKIP_SSL_OPT=1 can optionally be set to skip ssl-opt.sh tests
|
|
#
|
|
# WARNING: this script checks out a commit other than the head of the current
|
|
# branch; it checks out the current branch again when running successfully,
|
|
# but while the script is running, or if it terminates early in error, you
|
|
# should be aware that you might be at a different commit than expected.
|
|
#
|
|
# NOTE: you can comment out parts that don't need to be re-done when
|
|
# re-running this script (for example "get numbers before this PR").
