1) It seems the maxmind database is getting relatively frequent updates
which are causing differences in exact coordinates
2) GeoIP location lookups are not an exact science, I tried to pick some
ips which I thought would remain fairly static, but these things are
just guesses.
3) Moving to 2 decimal places should give us good enough results for
this test, according to:
http://gis.stackexchange.com/questions/8650/measuring-accuracy-of-latitude-and-longitude
"The second decimal place is worth up to 1.1 km: it can separate one
village from the next."
"The third decimal place is worth up to 110 m: it can identify a
large agricultural field or institutional campus."
Please note you need to define PHPUNIT_LONGTEST in config.php or phpunit.xml to get the tests to execute because it takes long time to fetch the geoip data and we do not want to DDOS geoPlugin server.
