LBAF Testing

Testing in LBAF are divided into two types of tests: Unit Tests and Acceptance Tests. Each test is checking for expected output.

Requirements for testing

A file which contains all required packages for testing purposes can be found under:

• <project-path>/requirements-3.<x>.txt, where <x> stands for python version.

Unit testing

• Unit Tests are checking for low level logic - functions, methods, classes
• In order to run unit tests one needs:

  cd <project-path>
  tox

• tox command will:
  • run all test defined in tox.ini
  • create artifacts directory in main project path <project-path>/artifacts
  • in <project-path>/artifacts following reports can be found:
    • coverage report (html and text)
    • pylint report (text)
  • all tests as well as coverage and pylint output are printed to stdout as well

Badges creation

• In order to create a badges for further use in repository:

  cd <project-path>
  mkdir badges
  PYLINT_SCORE=$(sed -n 's/^Your code has been rated at \([-0-9.]*\)\/.*/\1/p' ./artifacts/pylint.txt)
  anybadge --label=pylint --file=badges/pylint.svg --value=$PYLINT_SCORE 2=red 4=orange 8=yellow 10=green
  COVERAGE_SCORE=$(sed -n '/TOTAL/,/%/p' artifacts/coverage.txt | rev | cut -d" " -f1 | rev | tr -d % )
  anybadge --value=$COVERAGE_SCORE --file=badges/coverage.svg coverage

Acceptance tests

• Acceptance Tests are checking for correctness of business logic - based on input data test is checking for expected output
• This test is a run of LBAF Application, based on special test configuration:

  work_model:
  name: "AffineCombination"
  parameters:
    alpha: 1.
    beta: 0.
    gamma: 0.
  criterion:
    name: "Tempered"
    parameters:
      actual_destination_load: True
  deterministic_transfer: True
  n_iterations: 8
  n_rounds: 4
  fanout: 4
  phase_id: 0
  log_file: "data/synthetic_lb_data/data"
  file_suffix: json
  exodus: True
  x_procs: 2
  y_procs: 2
  z_procs: 1
  output_dir: "output"
  order_strategy: element_id
  logging_level: info

• test checks for the final imbalance which should be 0
