# Hello world smoketest test
# A minimal test for backend/cli/netconf/restconf
# See clixon-example/hello
# but this test is (more or less) self-contained for as little external dependencies as possible
# The test is free of plugins because that would require compilation, or pre-built plugins
# Restconf is internal native http port 80
# The minimality extends to the test macros that use advanced grep, and therefore more
# primitive pattern macthing is made
# Two variants exist, for poll and select event handling.

# Magic line must be first in script (see README.md)
