# Use a cache: Slightly speed up composer installation and building php-ast
cache:
  directories:
    - $HOME/.composer/cache
    - $HOME/.cache/phan-ast/build

# We invoke php multiple times via CLI in several tests, so enable the opcache file cache.
before_install:
  - ./tests/travis_setup.sh
  #- composer validate # Skip because 'Name "mattriverm/PhanUnusedVariable" does not match the best practice (e.g. lower-cased/with-dashes).
# Optional: --classmap-authoritative --prefer-dist makes running this test slightly faster,
# and imitates phan's recommended settings
install:
  - composer --prefer-dist --classmap-authoritative install

# TEST_SUITES contains 1 or more space-separated value for TEST_SUITE
# We have a fake TEST_SUITE which runs phan, and check if the exit code is non-zero and the standard output is non-empty.
# This is used instead of a unit test because Phan currently caches too much state for this to be run with other unit tests, and the configuration might end up different within a unit test.
# This was moved into a separate script to stop cluttering up .travis.yml
script:
  # Self-analyze (Includes checks for unused variables)
  - vendor/bin/phan
  # Run the test suite
  - cd tests; ./test.sh
