The tests here are based on David Huynh's Refine tutorial at
|
|
http://davidhuynh.net/spaces/nicar2011/tutorial.pdf The tests perform all
|
|
the Refine actions given in the tutorial (except the web scraping) and verify
|
|
the changes expected to be observed explained in the tutorial.
|
|
|
|
These tests require a connection to a Refine server either at
|
|
http://127.0.0.1:3333/ or by specifying environment variables
|
|
GOOGLE_REFINE_HOST and GOOGLE_REFINE_PORT.
