This is a major refactoring of the testsession module to use a persistent file
storage instead of using $_SESSION storage. The primary reason for this is for
out-of-band tests (e.g. simplifying Behat tests, and testing modules like
silverstripe-resque (https://github.com/stojg/silverstripe-resque)). Testing
the silverstripe-resque module without this is impossible as the PHP code
running the job has been started and loaded into memory long before you started
a testsession.
By default, this will create a TESTS_RUNNING.json file in your webroot, which
means that tests need to be run as a user who has permission to create files
there. In practice, this means your webroot needs to be owned by your webserver
user. The reason we store the file here is that it will show up as a changed
file in version control, so it’s more prominent if developers can’t figure out
why there are issues with database content.
API CHANGES:
- Add persistent file storage (using webroot/TESTS_RUNNING.json) as a base.
- Update TestSessionController to use new TestSessionEnvironment class.
- Moved extension points from TestSessionController to TestSessionEnvironment.
- Moved loadFixtureIntoDb from TestSessionController to TestSessionEnvironment.
- Moved setState from TestSessionController to TestSessionEnvironment.
- Deprecated the use of TestSessionController::setState()
FIXES:
- Fixes TestSessionRequestFilter to use new TestSessionEnvironment instead of
$_SESSION.
MINOR:
- Renamed TestSesssionRequestFilter.php to fix spelling error (three ’S’s)
- Class did not need renaming, just the file itself.
- Allow limited state setting when session is already in progress
- Allow test sessions without a test database
- Denote an “in progress” session through a “testsession.started” session flag rather than the usage of a temporary database
Otherwise we'll get into a catch22 if it's not set:
The manifest includes this _config.php, which in turn
throws a fatal exception on the token not existing.
It would be recreated a couple of lines further down in Core.php
when the ConfigManifest is pushed, but never gets this far.
