When we smog any of our cars, they get the "roller" test.

Different testing standards based on where (in CA) the car is registered. From California ARB (
http://www.bar.ca.gov/80_BARResources/ftp/pdfdocs/Reference%20Guide%20Final%2012-09%20V-2.pdf):
An
Enhanced Area is one which has been designated by the U.S. Environmental Protection Agency as not in attainment with federal health standards for ozone and are designated as an urbanized area. With some exceptions, vehicles registered in enhanced areas are subject to a loaded mode dynamometer emission test.
For
Basic and
Enhanced Areas, a Smog Check inspection is also required biennially.
Enhanced Areas: These areas do not meet federal or state air quality standards for ozone and carbon monoxide. Biennial Smog Check inspections are required in these areas. Additionally, a portion of the vehicles in Enhanced Areas must receive the biennial Smog Check at Test Only stations or special Test and Repair stations, known as Gold Shield. In order to measure NOx emissions,
most enhanced area vehicles are subject to a dynamometer loaded mode emissions test.
Basic Areas: Basic areas are less polluted then Enhanced Areas; however, due to their marginal air quality, biennial inspections are required. Basic Area vehicles can receive biennial testing/certification at licensed Test and Repair or Test Only stations.
Basic Area vehicles are subject to a two speed idle test. Loaded mode tests are not required in basic areas.
Change of Ownership Areas: These more rural areas of the state require Smog Check testing only when an affected vehicle changes ownership or is initially registered in California, except for gasoline vehicles 1975 model-years and older, and gasoline vehicles 4 or less model-years old.
Here's a map showing
Basic,
Enhanced, and
COO Areas (note that this is 2008 map and CARB no longer provides info -- e.g., ZIP Code locator -- on which areas are Basic, Enhanced, or COO. Only source I can tell now is CA DMV notifies you via registration renewal process.):
Hope this helps.
