how to run java/scala unit test in sbt

Question

I am new to the scala, scala project contains both scala and java unit test cases.

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import itest.Level2;
    @RunWith(Suite.class)
    @Suite.SuiteClasses({Level2.class}) // Level2.class is contains @test method
    class  OrganizationRegexModelComponentTester  implements ITest{
    
    }

itest.jar contains file Level2.class. i added

libraryDependencies += "junit" % "junit" % "4.11" % "test" // already added
libraryDependencies += "com.novocode" % "junit-interface" % "0.11" % "test"

testOnly company.extraction.api.util.TestJunitTwo
