Subject: unit-tests: Add environment variable to only run specific iterations
X-Git-Tag: 5.9.8dr4~13
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=644f74ad8f41d5d92dd465a930b86637902b93a6;p=thirdparty%2Fstrongswan.git

unit-tests: Add environment variable to only run specific iterations

Helpful when running with increased verbosity and only specific iterations
fail.
