From a command prompt, launch sbt at the root of your Scala project by typing in: sbt

To run all the tests in your Scala project using sbt, type the following command in the sbt shell: test

Run only one specific test in a Scala project using sbt:

From a command prompt, launch sbt at the root of your Scala project by typing in: sbt

To run a specific test in your Scala project using sbt, type the following command in the sbt shell: testOnly com.yourpackage.YourTestClassName

Run all the integration tests in a Scala project using sbt:

From a command prompt, launch sbt at the root of your Scala project by typing in: sbt

To run all the integration tests in your Scala project, type the following command in the sbt shell: it:test

NOTE: This assumes that you have an it folder under src

Run only a specific integration test in a Scala project using sbt:

From a command prompt, launch sbt at the root of your Scala project by typing in: sbt

To run a specific integraiton test in your Scala project using sbt, type the following command in the sbt shell: it:test-only com.yourpackage.YourTest

Run a specific test class and a specific method:

From a command prompt, launch sbt at the root of your Scala project by typing in: sbt

To run a specific test method from a specific test class in your Scala project, type the following command in the sbt shell: it:test-only com.yourpackage.YourTest -- -t "your test method name"

Run a main class or test class using sbt in a Scala project and analyze the stacktrace in IntelliJ:

From a command prompt, launch sbt at the root of your Scala project by typing in: sbt

Run your main class or test class and if it crashes and produces a stacktrace, you can debug the stacktrace by copying the exception into IntelliJ -> select the Analyze menu -> select the Analyze stacktrace.

NOTE: You should now be able to click on the class names and navigate to the source for the class or method in IntelliJ.
