Summary
This patch fixes the issue that
rake testdoes not actually testC extension for CRuby.
The Bug
The
testtask is defined as follows:https://github.com/flori/json/blob/7ec73ad240d45018f119f5d1a2eaa479ad3f9038/Rakefile#L109-L110
This invokes
:test_pureand:test_extconsecutively.:test_pureassignsENV['JSON'] = 'pure'as follows:https://github.com/flori/json/blob/7ec73ad240d45018f119f5d1a2eaa479ad3f9038/Rakefile#L97-L98
However,
:test_extfor CRuby does not changeENV['JSON'].https://github.com/flori/json/blob/7ec73ad240d45018f119f5d1a2eaa479ad3f9038/Rakefile#L252
This lead to
require 'json/pure'in test_helper.rb, which test only the pure version.https://github.com/flori/json/blob/7ec73ad240d45018f119f5d1a2eaa479ad3f9038/tests/test_helper.rb#L2-L4
How to Fix It
I have added
:set_env_extto guarantee that:test_extassignsENV['JSON'] = 'ext'.This is just like
test_extin JRuby version
