I have an IntelliJ project, versioned in git.

How can I run all JUnit test classes, that I have modified since my last commit?

intellij-idea junit git java

If your stack is composed of GIT and maven We came up with this shell script that is appended at the end of ours Jenkins Compilation jobs :

for s in `git diff --name-only HEAD~`
do
if [[ $s == *".java" ]]; then
  s=$(echo $s | tr '/' '.')
  s=$(echo ${s%.java})
  s=${s/.java/}
  s=${s/src./}Test
  echo "will test : $s"
  mvn -Dtest=$s  -DfailIfNoTests=false -Dfile.encoding=UTF-8 test-compile surefire:test
fi
done

Explanations :

Get the last commited files
for each
 if it is a java file
   convert name (in unix format) to FQN Test class name without extension
   run the maven test target

note : ours filenames for test follow the convention of appending Test at the end of the class file name. Adapt to your own conventions

This library seems to provide similar functionality: https://github.com/rpau/junit4git

This is a JUnit extension that ignores those tests that are not related with your last changes in your Git repository.
