Using the Spock based on JUnit5 engine
Sample project with Spock/Groovy and JUnit5
This sample code shows you how the Surefire plugin works with Spock/Groovy and JUnit5. The project contains two dependencies spock-core
and junit-jupiter-engine
, and Groovy compiler gmavenplus-plugin
.
You can create tests in test source directory for Groovy (i.e., src/test/groovy
). This is an example with parameterized test which is executed twice.
import pkg.Calculator import spock.lang.Specification class CalculatorTest extends Specification { def "Multiply: #a * #b = #expectedResult"() { given: "Calculator" def calc = new Calculator() when: "multiply" def result = calc.multiply( a, b ) then: "result is as expected" result == expectedResult println "result = ${result}" where: a | b | expectedResult 1 | 2 | 3 -5 | 2 | -3 } }
If you want to additionally mix Spock tests with the JUnit4, you should add the JUnit Vintage Engine in the test dependencies.
