Can one configure Android Studio to run a gradle task before submitting a Git commit?

Question

I'm using Android Studio (itellij) IDE and the built-in support for Git as VCS.

Is there any hook / option to predicate submitting the commit on a successful run of some gradle task. As you may suspect, I'm trying to automate running the entire unit test suite and blocking the commit locally from going through if any unit test fails.

Answer 1

still need to investigate how git commit hooks even work

As shown in this gist

create a hooks directory in your .git folder and just name the file "pre-commit"

(make it executable too, if you are not on Windows)

But as mentioned in your linked question by sschuberth:

Adding long-running tasks in a pre-commit hook generally is a bad idea as it blocks you from working.
Such checks should be done on a CI system that gates merges of commits that break tests

In other words, commit and push to an intermediate repo with a pre-receive hook, which will reject your push if the entire unit test suite fails at any point.

The OP Creos points out in the comments the following pre-commit hook gist example by Chad Maughan, as a good template:

#!/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

# return the './gradlew test' exit code
exit $RESULT
