Spock Test Example

import spock.lang.Specification
import spock.lang.Subject
import spock.lang.Unroll

@Unroll     // Indicates that iterations of a data-driven feature should be made visible as separate features to the outside world
class CheckoutOrderTest extends Specification {

    @Subject    // Indicates which objects/classes are the subjects of a specification
    CheckoutOrder checkoutOrder

    def setup() {  // Performs these actions before the start of every test
        checkoutOrder = new CheckoutOrder()
    }

    def cleanup() { // Performs these actions after the end of every test
        
    }

    def "Retrieve the value of the scanned item #itemToScan"() {  // Defines a test case with a unique description of the test
        given:      // Setup specifically required for this test
            checkoutOrder.scanItem(itemToScan)

        when:       // The action that is being tested for this test
            def total = checkoutOrder.getTotal()

        then:       // The assertions for truthy for this test
            noExceptionThrown()
            total == price
        
        where:      // Data-driven inputs for this test.  Each row represents a separate test to be executed.
            itemToScan  | price
            "bread"     | 1.00
            "milk"      | 3.16
    }
