Python wrappers for generating CTest and submitting to CDash without a CMake build system

PyCTest

Travis	AppVeyor

Benefits

• Integration into continuous integration systems (e.g. Travis, AppVeyor, CircleCI, etc.) and pushing to CDash dashboard will combine all the results in one place
  • The warnings and errors are enumerated in CDash (no more parsing stdout logs for errors)
• Easily create platform-independent testing
• No need to migrate build system to CMake -- just specify pyctest.BUILD_COMMAND

General Setup

• Add PyCTest to conda environment: conda install pyctest
• Write a driver Python script, e.g. pyctest-runner.py, in top of the source code tree

Example for Python project

The following is an example for a Python code with a compiled C extension that uses nosetests for unit-testing:

#!/usr/bin/env python

import os, sys, platform
import pyctest.pyctest as pyctest
import pyctest.helpers as helpers

parser = helpers.ArgumentParser("ProjectName", source_dir=os.getcwd(),binary_dir=os.getcwd(), vcs_type="git")
args = parser.parse_args()

pyctest.BUILD_NAME = "{}".format(args.build)
pyctest.BUILD_COMMAND = "python setup.py build_ext --inplace"

test = pyctest.test()
test.SetName("unittest")
# insert the command to run the tests for project
test.SetCommand(["nosetests"])

pyctest.run()

Example for autotools project

#!/usr/bin/env python

import os, sys, platform
import multiprocessing as mp
import pyctest.pyctest as pyctest
import pyctest.helpers as helpers

parser = helpers.ArgumentParser("ProjectName", source_dir=os.getcwd(), binary_dir=os.getcwd(),
                                vcs_type="git")
parser.add_argument("-n", "--build", type=str, required=True, help="Build name for identification")
args = parser.parse_args()

# CONFIGURE_COMMAND can only run one command so if autogen is required, just execute it here
cmd = pyctest.command(["./autogen.sh"])
cmd.SetWorkingDirectory(pyctest.SOURCE_DIRECTORY)
cmd.SetErrorQuiet(False)
cmd.Execute()

pyctest.BUILD_NAME = "{}".format(args.build)
pyctest.CONFIGURE_COMMAND = "./configure"
pyctest.BUILD_COMMAND = "make -j{}".format(mp.cpu_count())

test = pyctest.test()
test.SetName("unittest")
# insert the command to run the tests for project
test.SetCommand(["./run-testing.sh"])

pyctest.run()

Example for CMake project

#!/usr/bin/env python

import os
import sys
import platform
import multiprocessing as mp
import pyctest.pyctest as pyctest
import pyctest.helpers as helpers

binary_dir = os.path.join(os.getcwd(), "build-ProjectName")
parser = helpers.ArgumentParser("ProjectName", os.getcwd(), binary_dir)
parser.add_argument("-n", "--build", type=str, required=True, help="Build name for identification")
args = parser.parse_args()

pyctest.BUILD_NAME = "{}".format(args.build)
pyctest.UPDATE_COMMAND = "git"
pyctest.CONFIGURE_COMMAND = "cmake {}".format(pyctest.SOURCE_DIRECTORY)
pyctest.BUILD_COMMAND = "cmake --build {} --target all -- -j{}".format(pyctest.BINARY_DIRECTORY, mp.cpu_count())

test = pyctest.test()
test.SetName("unittest")
# insert the command to run the tests for project
test.SetCommand(["./run-testing.sh"])

pyctest.run()

Python Modules

• import pyctest -- global package
• import pyctest.pyctest -- CTest module
• import pyctest.pycmake -- CMake module
• import pyctest.helpers -- Helpers module
  • includes command line arguments (argparse) for PyCTest

Direct Access to CMake/CTest/CPack Executables

• python -m pyctest.cmake <ARGS> == cmake <ARGS>
• python -m pyctest.ctest <ARGS> == ctest <ARGS>
• python -m pyctest.cpack <ARGS> == cpack <ARGS>

Following Python code:

from pyctest.ctest import CTest
from pyctest.cmake import CMake
from pyctest.cpack import CPack

CMake({"CMAKE_BUILD_TYPE":"Release"}, os.getcwd(), "-G", "Ninja")
CTest("--build-and-test", os.getcwd(), "-VV")
CPack("-G", "TGZ")

is equivalent to the following shell commands:

$ cmake -DCMAKE_BUILD_TYPE=Release ${PWD} -G Ninja
$ ctest --build-and-test ${PWD} -VV
$ cpack -G TGZ

Standard Configuration Variables

• pyctest.PROJECT_NAME
• pyctest.SOURCE_DIRECTORY
• pyctest.BINARY_DIRECTORY
• pyctest.SITE
• pyctest.BUILD_NAME
• pyctest.TRIGGER
• pyctest.CHECKOUT_COMMAND
• pyctest.BUILD_COMMAND
• pyctest.MODEL
• pyctest.CUSTOM_COVERAGE_EXCLUDE
• pyctest.CUSTOM_MAXIMUM_NUMBER_OF_ERRORS
• pyctest.CUSTOM_MAXIMUM_NUMBER_OF_WARNINGS
• pyctest.CUSTOM_MAXIMUM_PASSED_TEST_OUTPUT_SIZE

Setting Arbitrary Variables

    pyctest.set("CTEST_TOKEN_FILE", "${CMAKE_CURRENT_LIST_DIR}/.ctest-token")

Generating a Test

    test = pyctest.test()
    test.SetName("nosetests")
    test.SetCommand(["nosetests", "test", "--cover-xml", "--cover-xml-file=coverage.xml"])
    # set directory to run test
    test.SetProperty("WORKING_DIRECTORY", pyctest.BINARY_DIRECTORY)
    test.SetProperty("RUN_SERIAL", "ON")
    test.SetProperty("ENVIRONMENT", "OMP_NUM_THREADS=1")

Examples

• Basic example
• Advanced example
  • includes submission to CDash dashboard

CDash Integration Example

Results from running the TomoPy example can be found at the TomoPy CDash Testing Dashboard @ NERSC

• Python code with C extensions without CMake build system
• The build logs from "python setup.py install" are registered in the "Build" section
• The nosetests test command + other are wrapped into CTests

Testing Example

PyCTest can be used to simple execute tests and submit to a dashboard without any configuration, build, etc. steps
