   5 """Runs Browsermark CSS, DOM, WebGL, JS, resize and page load benchmarks.
   6
   7 Browsermark benchmark suite have five test groups:
   8 a) CSS group: measures your browsers 2D and 3D performance, and finally executes
   9   CSS Crunch test
  10 b) DOM group: measures variety of areas, like how well your browser traverse in
  11   Document Object Model Tree or how fast your browser can create dynamic content
  12 c) General group: measures areas like resize and page load times
  13 d) Graphics group: tests browsers Graphics Processing Unit power by measuring
  14   WebGL and Canvas performance
  15 e) Javascript group: executes number crunching by doing selected Array and
  16   String operations
  17 Additionally Browsermark will test your browsers conformance, but conformance
  18 tests are not included in this suite.
