Git pre-push hooks

Question

I would like to run a unit-tests before every git push and if tests fails, cancel the push, but I can\'t even find pre-push hook, there is pre-commit and pre-rebase only.

Answer 1

Git got the pre-push hook in the 1.8.2 release.

Pre-push hooks are what I needed along with pre-commit hooks. Apart from protecting a branch, they can also provide extra security combined with pre-commit hooks.

And for an example on how to use (taken and adopted and enhanced from this nice entry)

Simple example to login to vagrant, run tests and then push

#!/bin/bash
# Run the following command in the root of your project to install this pre-push hook:
# cp git-hooks/pre-push .git/hooks/pre-push; chmod 700 .git/hooks/pre-push

CMD="ssh vagrant@192.168.33.10 -i ~/.vagrant.d/insecure_private_key 'cd /vagrant/tests; /vagrant/vendor/bin/phpunit'"
protected_branch='master'

# Check if we actually have commits to push
commits=`git log @{u}..`
if [ -z "$commits" ]; then
    exit 0
fi

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

if [[ $current_branch = $protected_branch ]]; then
    eval $CMD
    RESULT=$?
    if [ $RESULT -ne 0 ]; then
        echo "failed $CMD"
        exit 1
    fi
fi
exit 0

As you can see the example uses a protected branch, subject of the pre-push hook.
