Running Groovy unittests from the command-line

Example.groovy

class Example {
    def hhg() { 42 }
}
    

ExampleSpec.groovy

import spock.lang.*
class ExampleSpec extends Specification {

    def "It must be 42" () {
        def ex = new Example()
        expect:
            ex.hhg() == 6*9
    }
}

ExampleTest.groovy

import static org.junit.Assert.*
import org.junit.*

class ExampleTest {
    @Test
    void isIt42() {
        def ex = new Example()
        assertTrue ex.hhg() == 6*9
    }
}

@grab doesn't have to use a network if you have some local cache/repo. You can also add spock jar(s) to a ${user.home}/.groovy/lib or ${groovy.home}/lib directory.

Ok. Thanks. I now have something that works.

groovyc *.groovy
if [ $? -eq 0 ]; then
  groovy HikerSpec
fi

But it still hard-wires the name HikerSpec.
Do you know if that can be fixed?
