Script Trace

set -e

rm -rf student-submission
mkdir student-submission

git clone $1 student submission
cp TestListExamples.java student-submission
cd student-submission

CPATH=.:../lib/hamcrest-core-1.3.jar:../lib/junit-4.13.2.jar

• set -e is used to exit the shell script, if the exit code is not 0.
• rm -rf student-submission and mkdir student-submission is going to remove the old student-submission and create a new directory.
• git clone $1 student submission and cp TestListExamples.java student-submission is going to clone the new student submission repository into the diretory and moved the TestListExamples.java into this diretory.
• cd student-submission is using to locate the student-submission diectory.
• CPATH is creating a short variable for calling the JUNIT.
  

if [[ -f ListExamples.java ]];
then
    echo "FILE FOUND (1/1)"
else
    echo "FILE NOT FOUND (0/1)"
    echo "SCORE: 0/5"
    exit 1
fi

• Using the -f command to search the whether ListExamples.java file exist or not.
  
  • If the file exists, the student will have one points.
  • otherwise, the student will don’t have any point and exit the grade script immediately.
    

set +e

javac -cp $CPATH *.java > compile-error.txt

if [[ $? -eq 0 ]]
then
    echo "COMPILED SUCCESFFULLY (1/1)"
else
    echo "COMPILED UNSUCCESSFULLY (0/1)"
    cat compile-err.txt
    echo "SCORE: 0/5"
    exit 2
fi

• set +e is used to let the script keep running after exit code is ran.
• The if statement is trying to find out whether exit code is equal to zero or not
  
  • If the exit code is zero, the student will get one point
  • otherwise, the student will don’t have point. Then the system will print out the compile-error.txt with stderr to let student to know where do they get wrong
    

java -cp $CPATH org.junit.runner.JUnitCore TestListExamples > test-error.txt

if [[ $? -eq 0 ]]
then 
    echo "ALL TESTS PASSED"
    echo "SCORE: 5/5"
    exit
else
    echo "TEST FAILED"
    echo "SCORE: 0/5"
    cat test-err.txt
    exit 3
fi

• Using the java to run the TestListExamples and the stderr will stored into a new file called test-error
• The if statement will try to find out whether the exit code of java is equal to zero or not
  • It do equal to zero, then the student will get full point
  • otherwise, the student will not receive the point and print out the test-error file to let student know where do they get wrong and script stop and exit.
