# The targets in this Makefile set up and execute tests inside
# a Docker container for the given artifact


# Paths to build artifacts are based on the locations where EC
# will provide them, relative to this Makefile.
# For example, 64-bit Linux p4api.tgz will be provided in:
#   <workspace>/depot/<codeline>/p4-bin/bin.linux26x86_64
# Whereas this Makefile is in:
#   <workspace>/depot/<codeline>/p4-php/sanity_test/Makefile
# Therefore, the artifact is available in:
#   ../../p4-bin/bin.linux26x86_64/p4api.tgz


# These are the targets EC or Humans call:

p4php7.archive-test : p4php7.archive.ubuntu16 p4php7.archive.centos7


# These are the targets that do the work

# Check for programs that tests depend on
depcheck : check-docker # list dependency-checking targets here
	$(info Dependency check passed)

check-docker : ; $(info ) $(info Checking for Docker) @which docker > /dev/null

# Reusable base images
# These images are not removed with 'make clean'
# Docker will use cached images if they exist, thereby speeding up tests
#  and lessening reliance on upstream package servers
