# For normal use this package can just be tested with "go test" as standard,
# but this script is an alternative to allow the tests to be run somewhere
# other than where they are built.

# The primary use for this is cross-compilation, where e.g. we can produce an
# archive that can be extracted on a Windows system to run the e2e tests there:
#    $ GOOS=windows GOARCH=amd64 ./make-archive.sh
#
# This will produce a zip file build/terraform-s2stest_windows_amd64.zip which
# can be shipped off to a Windows amd64 system, extracted to some directory,
# and then executed as follows:
#    set TF_ACC=1
#    ./e2etest.exe
# Since the test archive includes both the test fixtures and the compiled
# terraform executable along with this test program, the result is
# self-contained and does not require a local Go compiler on the target system.
