fillit_compare

A shellscript to compare the result of 2 fillit program

About the script

• I used this script to test the result of my fillit project by comparing the result with other students project.
• The script uses Tetriminos-generator to generate a random input.
• Then, the script runs two fillit program and compare the results.
• If there is a different, the script will stop running. You can then look at the input, outputs and the different file.

How to use the scipt

• Download and install Tetriminos-generator. You can see the instruction in its project page.
• Put this script in the Tetriminos-generator root directory.
• Put two fillit programs each one in each folder at the Tetriminos-generator root directory.
• So the structure will look like this:

   Tretriminos-generator/
   	compare.sh
   	first-fillit-folder/
   		fillit
   	second-fillit-folder/
   		fillit
  

• Don't forget to use make command on each fillit.
• Edit compare.sh
  • NUM is the number of times the test will run.
  • FIRST is your first fillit directory name.
  • SECOND is your second fillit derectory name.
• Run:

   sh compare.sh
  

compare.sh

#!/bin/sh

NUM=10000
FIRST=first
SECOND=second

rm first_output.txt
rm second_output.txt
rm diff.txt

a=0

while [ $a -lt $NUM ]
do
	echo $a
	./tetri-gen -v -f 4
	$(FIRST)/fillit sample.fillit > first_output.txt
	$(SECOND)/fillit sample.fillit > second_output.txt
	diff first_output.txt second_output.txt > diff.txt
	if [ -s diff.txt ]
	then
		break
	fi
	rm first_output.txt
	rm second_output.txt
	rm diff.txt
	a=`expr $a + 1`
done
