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.
Execute a Single Test Class The Maven surefire plugin provides a test parameter that we can use to specify test classes or methods we want to execute. If we want to execute a single test class, we can execute the command mvn test -Dtest=”TestClassName”.
A multi-module project is built from an aggregator POM that manages a group of submodules. In most cases, the aggregator is located in the project's root directory and must have packaging of type pom. The submodules are regular Maven projects, and they can be built separately or through the aggregator POM.
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
