The SilverStripe project structure complicates the travis test run, and
the goal of this branch is to prevent it from being necessary.
- Unit tests can be run simply with PHPUnit.
- Behat test can be run with the silverstripe/serve module
Note that initially this commit doesn’t cater to the behat tests.
As part of this, we allow dev packages to be installed when testing
These settings don’t affect projects that use framework, only when
framework’s composer install / require calls are used themselves.
Since SS4 is pre-stable, these are important. They can probably be
removed once SS4 stable (and stable versions of support packages) have
been released.
