# -------------------------------------------------------------------------------------------
# When executed, we rely on four variables being set in the environment:
#
# [The reason for being environment variables rather than parameters is historical. No reason
# why it couldn't be updated.]
#
#    SOURCES_DRIVE       is the drive on which the sources being tested are cloned from.
#                        This should be a straight drive letter, no platform semantics.
#                        For example 'c'
#
#    SOURCES_SUBDIR      is the top level directory under SOURCES_DRIVE where the
#                        sources are cloned to. There are no platform semantics in this
#                        as it does not include slashes. 
#                        For example 'gopath'
#
#                        Based on the above examples, it would be expected that Jenkins
#                        would clone the sources being tested to
#                        SOURCES_DRIVE\SOURCES_SUBDIR\src\github.com\docker\docker, or
#                        c:\gopath\src\github.com\docker\docker
#
#    TESTRUN_DRIVE       is the drive where we build the binary on and redirect everything
#                        to for the daemon under test. On an Azure D2 type host which has
#                        an SSD temporary storage D: drive, this is ideal for performance.
#                        For example 'd'
#
#    TESTRUN_SUBDIR      is the top level directory under TESTRUN_DRIVE where we redirect
#                        everything to for the daemon under test. For example 'CI'.
#                        Hence, the daemon under test is run under
#                        TESTRUN_DRIVE\TESTRUN_SUBDIR\CI-<CommitID> or
#                        d:\CI\CI-<CommitID>
#
# In addition, the following variables can control the run configuration:
#
#    DOCKER_DUT_DEBUG         if defined starts the daemon under test in debug mode.
#
#    SKIP_VALIDATION_TESTS    if defined skips the validation tests
#
#    SKIP_UNIT_TESTS          if defined skips the unit tests
#
#    SKIP_INTEGRATION_TESTS   if defined skips the integration tests
#
#    SKIP_COPY_GO             if defined skips copy the go installer from the image
#
#    DOCKER_DUT_HYPERV        if default daemon under test default isolation is hyperv
#
#    INTEGRATION_TEST_NAME    to only run partial tests eg "TestInfo*" will only run
#                             any tests starting "TestInfo"
#
#    SKIP_BINARY_BUILD        if defined skips building the binary
#
#    SKIP_ZAP_DUT             if defined doesn't zap the daemon under test directory
#
#    SKIP_IMAGE_BUILD         if defined doesn't build the 'docker' image
#
#    INTEGRATION_IN_CONTAINER if defined, runs the integration tests from inside a container.
#                             As of July 2016, there are known issues with this. 
#
#    SKIP_ALL_CLEANUP         if defined, skips any cleanup at the start or end of the run
#
#    WINDOWS_BASE_IMAGE       if defined, uses that as the base image. Note that the
#                             docker integration tests are also coded to use the same
#                             environment variable, and if no set, defaults to microsoft/windowsservercore
#
#    LCOW_BASIC_MODE          if defined, does very basic LCOW verification. Ultimately we 
#                             want to run the entire CI suite from docker, but that's a way off.
#                            
#    LCOW_MODE                if defined, runs the entire CI suite
#
