How to execute tests in a single project only in multi-module build?

I have a multi-module build, and would like to run tests for different sub-projects independently.

Is there a way to do this in sbt, e.g. if my multi-project build has a core and commons projects, I'd like to only run test in the commons project.

Run sbt commons/test. See detailed explanation in Scopes.

You may also use the combination of two commands from sbt - changing the current project using project and executing test afterwards.

sbt "project commons" test

You can also use

sbt "; project commons; test"

It you are running sbt in interactive mode:

> project commons
> test

You can switch back to core with:

> project core

Never mind, I came across this: How to execute package for one submodule only on Jenkins?

sbt "project core" test

Another way to do this.

Get into SBT interactive mode

> sbt

sbt:core> commons / test

No need to switch between projects.

to run sbt test only for ONLY the submodules having added, modified on deleted files, if you use git:

 while read -r proj ; do sbt "project $proj" test ; \
 done < <(git status --porcelain | cut -c 3- | cut -d/ -f1
