"""Runs Browsermark CSS, DOM, WebGL, JS, resize and page load benchmarks.

Browsermark benchmark suite have five test groups:
a) CSS group: measures your browsers 2D and 3D performance, and finally executes
  CSS Crunch test
b) DOM group: measures variety of areas, like how well your browser traverse in
  Document Object Model Tree or how fast your browser can create dynamic content
c) General group: measures areas like resize and page load times
d) Graphics group: tests browsers Graphics Processing Unit power by measuring
  WebGL and Canvas performance
e) Javascript group: executes number crunching by doing selected Array and
  String operations
Additionally Browsermark will test your browsers conformance, but conformance
tests are not included in this suite.
