I'm new to blender and hit a bug probably.
I checked the material/texture/rendered view but the material is not being applied. I also created a new project and tested with a simple cube and tried the voronoi texture. The texture doesn't seem to work while I successfully applied bevel. I have checked the documentation and saw some tutorials and the followed the same steps as the videos but the material won't work.
EDIT:
OS is Ubuntu 16.04 LTS.
Using cycles render, it didn't work in blender render either. I was using 2.76 when I posted the question upgraded to 2.79 and the issue persists.
I assume material will be applied when I left click or press enter by selecting a certain material. Here's a screenshot
