 """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.
