Subject: Use Optional::Dependencies for CDBICompat and its tests
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=c8dc7d333;hp=236b59c817665c1168a0eeee0562ed1e2df68e39;p=dbsrgits%2FDBIx-Class.git

Use Optional::Dependencies for CDBICompat and its tests

This allows the test to check for them before loading DBICTest and
DBIC, thus speeding up the test skips a lot (down from 14s to 1s for
'prove -l t/cdbi' on my Linux box, and down from 1026s to 871s for the
whole test suite on a Windows VM).
