Mocking java.util.logging.Logger while using jersey












0















We are using maven, jersey, Mockito in our project, with java.util.logging for Logs. While running Junit test with mocked objects, log.log() method throwing InvalidUseOfMatchersException. Below is the sample code.



import javax.inject.Inject;
import java.util.logging.Logger;
import java.util.logging.Level;

public class Sample{

@Inject
Logger log;

public String runLog(String name){
log.log(Level.INFO, "Name = "+name);
return "name";
}
}

public class SampleTest{

@InjectMocks
Sample sample;

@Mock
Logger log;


public void setup() throws Exception(){
MockitoAnnotations.initiMocks(this);
}

@Test
public void testRunLog(){
doNothing().when(log).log(any(Level.class), anyString());
String s = sample.runLog(anyString());
assertNotNull(s);
}

}

          Here is the problem:



          String s = sample.runLog(anyString());


          You can use anyString (and all other matcher methods) only in verify and when methods.



          If you don't care about exact value you pass then pass some constant or random string.

          • Thanks a lot. This actually worked for me. But if I comment the logs and other java code works perfect even with anyString(). Is there any specific reason for this??

          • Yes, but to explain it I need to explain how mocks works internally. I don't think I'm able because it involve tons of MAGIC.
