#!/bin/bash
# check if the arguments are valid
if [ $# -ne 2 ]; then
echo "Usage: $0 [Times] [2A/2B/2C/2D - Case Insensitive]"
exit 1
fi
# assign the arguments to variables
times=$1
test=${2^^}
# loop for the given number of times
for ((i=1; i<=times; i++))
do
# execute the command and append the output to result.txt
go test -run $test -race >> result.txt
done
By saving this script in a file e.g. test_multiple.sh , you could run ./test_multiple.sh 25 2A to test Lab 2A for 25 times
Debug Print Log
In util.go, it provide a simple helper function for DPrintf(), so we could enable it by controlling const Debug. It also print the timestamp which reduce the debugging effort.
I had change util.go so I could select the log that I actually need for ease of debugging.

Deadlock Detection
In normal case, we use sync.Mutex as mutex, but we could use deadlock.Mutex as mutex to detect deadlock. This is developed by sasha-s and here is the repository.
