How To Write a Java Unit Test for the Method inside Another Method?-CodePudding

 Public Class DailyJob(){

   public void runJob(ScheduleJob currentJob) {
    
    try {
            int employee = employeeService.getEmployeeNum();
            JobPerformance jobPerformance = performanceService.searchJobPerformance(employee);
            if(jobPerformance.size() >0 ) {
                currentJob.setRecord("success");
           }
            else {
                currentJob.setRecord("failed");
                }
    }
    catch{
    //catch error
         }
      }
  }

By now I want to write a Junit test for runJob(). But how can I setup the value I prefer into 'employee' parameter in Junit Test while I test runJob()? Anyone know how to implement it?

CodePudding user response：

You can use Mockito. You setup stubbing, which will return desired value. Also you can stub for multiple calls by

.thenReturn(9, 10, 7);

import org.junit.jupiter.api.Test;

import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.when;


public class MyTest {

    @Test
    void test() {
        EmployeeService employeeService = mock(EmployeeService.class);
        when(employeeService.getEmployeeNum()).thenReturn(9);
       
    }
}
