Using PowerMock with Spock

Question

I have a class with a few static methods.I need to Mock these static methods. I know PowerMock does this,but I was not able to find any tutorials/materials that shed some light

Answer 1

I was stuck here for a while too. After searching for hours, I saw this github repo: https://github.com/kriegaex/Spock_PowerMock.

I tried adding a PowerMockRule which essentially enabled me to use PowerMock together with Spock. I had to add these dependencies. Version is at 1.5.4

   
      org.powermock
      powermock-module-junit4
      ${powermock.version}
      test
   

   
        org.powermock
        powermock-module-junit4-rule
        ${powermock.version}
        test
    

    
        org.powermock
        powermock-classloading-xstream
        ${powermock.version}
        test
    

My class looks like this:

import org.junit.Rule
import org.mockito.Mockito
import org.powermock.api.mockito.PowerMockito
import org.powermock.core.classloader.annotations.PrepareForTest
import org.powermock.modules.junit4.rule.PowerMockRule
import spock.lang.Specification

@PrepareForTest([SomeStaticClass.class])
public class FlightFormSpec extends Specification { 

    @Rule PowerMockRule powerMockRule = new PowerMockRule();

    def "When mocking static"() {
        setup :
            PowerMockito.mockStatic(SomeStaticClass.class)

        when :
            Mockito.when(SomeStaticClass.someStaticMethod()).thenReturn("Philippines!");

        then :
            SomeStaticClass.someStaticMethod() == "Philippines!"
    }
}
