[tarekbecker]

Works on mac. Please test on windows.

put in file ./.git/hooks/pre-commit execute chmod +x ./.git/hooks/pre-commit

test to commit with a failing test

#!/bin/sh
# this hook is in SCM so that it can be shared
# to install it, create a symbolic link in the projects .git/hooks folder
#
#       i.e. - from the .git/hooks directory, run
#               $ ln -s ../../git-hooks/pre-commit.sh pre-commit
#
# to skip the tests, run with the --no-verify argument
#       i.e. - $ 'git commit --no-verify'

# stash any unstaged changes
git stash -q --keep-index

# run the tests with the gradle wrapper
./gradlew test

# store the last exit code in a variable
RESULT=$?

# unstash the unstashed changes
git stash pop -q

if git rev-parse --verify HEAD >/dev/null 2>&1 ; then
   against=HEAD
else
   # Initial commit: diff against an empty tree object
   against=4b825dc642cb6eb9a060e54bf8d69288fbee4904
fi
# Find files with trailing whitespace
# Doubled commands are _linux_version_ || _mac_osx_version_
for FILE in $(
    git diff-index --check --cached $against -- | \
    sed '/^[+-]/d' | \
    ( sed -r 's/:[0-9]+:.*//' 2>/dev/null || \
      sed -E 's/:[0-9]+:.*//' ) | \
    uniq
); do
  # Fix them!
  ( sed -i 's/[[:space:]]*$//' "$FILE" > /dev/null 2>&1 || \
    sed -i '' -E 's/[[:space:]]*$//' "$FILE" )
  echo "Removed trailing whitespace from $FILE"
  git add "$FILE"
done

exit $RESULT

works on windows too. instruction: execute chmod +x ./.git/hooks/pre-commit

is not applicable for windows, it only changes the modifier for the file.

prevent of pushing to master create a pre-push file in the hook folder

#!/bin/bash

protected_branch='master'
current_branch=$(git symbolic-ref HEAD | sed -e 's,.*/\(.*\),\1,')

if [ $protected_branch = $current_branch ]
then
    exit 1 # push will not execute
else
    exit 0 # push will execute
fi
