Adds unit test for bridge implementations:
- Custom functions must be in protected or private scope
- getName() must return a valid string (non-empty)
- getURI() must return a valid URI
- Each bridge must define constants for NAME, URI, DESCRIPTION and
MAINTAINER. CACHE_TIMEOUT and PARAMETERS are optional.
The unit test is written for PHPUnit 6.x and will automatically be
tested by Travis-CI for PHP 7.0 (see .travis.yml).
Remarks:
Unit tests for bridge data were scrapped in #378 for complexity
reasons (tests would have to be maintained for each bridge). This
unit test, however, is written for testing all bridges without
taking specific implementation details into account.
Travis CI upgraded the linux build environment from Ubuntu Precise
to Ubuntu Trusty with Trusty becoming the default build environment
as of August 2017:
https://docs.travis-ci.com/user/reference/overview/
A bug in the configuration of the Ubuntu Trusty distro causes all
builds except nightly to fail. The PHP include_path is set to
include_path='.:/home/travis/.phpenv/versions/5.6.31/share/pear'
instead of
include_path='.:/home/travis/.phpenv/versions/5.6.31/lib/php/pear'
which causes phpcs to fail because it cannot resolve import paths.
This commit adds a hotfix to .travis.yml that circumvents the
issue by overwriting the include_path during initialization. This
hotfix should be removed once a solution is found.
This bug is tracked via
https://github.com/travis-ci/travis-ci/issues/8487
Travis CI recently updated the default distribution from Ubuntu
Precise to Ubuntu Trusty, which causes all builds except nightly
to fail.
For unknown reasons phpcs is unable to locate "PHP/CodeSniffer/
autoload.php" causing it to fail with a fatal error
The root cause of the failure is unknown. We explicitly return to
the previous build system (Ubuntu Precise) for builds to work again.
See the migration guide for reference:
https://docs.travis-ci.com/user/precise-to-trusty-migration-guide/
Notice: Ubuntu Precise is retired as of September 2017 and will be
decommissioned in the near future:
