[PATCH 0/5][Outreachy] modernizing the test scripts

This is my first patch series to the GIT mailing list. I followed the
link[1] and t7001 patches to modernize and clean up the test scripts.

This patch series : 
 -modernize the three test scripts : t7101 , t7201 and t102. 
 - cleans up with 5 types of changes in all the three scripts.
   1. Converting the old old style test format to new one
   2. Removing blankspaces in test bodies 
   3. Removing whitespaces after the redirect operator, according to
      Codingguidelines .  
   4. Using git -C instead of cd 
   5. Placing all commands in seperate lines. 

Also, I have tested the scripts and set up travis CI[2].
