The Vincenty formula can fail to converge for antipodal points (see http://en.wikipedia.org/wiki/Vincenty's_formulae#Nearly_antipodal_points), so those test cases are removed. These tests fail with the latest V8 due to optimization of trig functions with lookup tables. For example, Math.cos(Math.PI / 2) is no longer calculated based on the value of Math.PI / 2 (which is different than the actual value of π / 2). Instead, values close to multiples of π / 2 are determined to be 0 (which is arguably what you want). Previously the tests were relying on very small numbers being returned in this case.

Run the test suite with PhantomJS
With PhantomJS installed, and assuming phantomjs is in the PATH:
$ phantomjs mocha-phantom.coffee ol.html
(Works with PhantomJS 1.6.1, untested with other versions.)
This command can also be run by doing ./build.py test at the root of ol3.
Make sure that the polvr web server is running (./build.py serve), otherwise
you will most likely see something like 0 specs, 0 failures in 0.001s..
Tip for TDD'ers: to make PhantomJS run the test suite continuously each time
a spec file is changed you can use nosier (http://pypi.python.org/pypi/nosier)
and do nosier -p test -p src "./build.py test".
