java - Intellij 不将 Mockito 类识别为测试类

Question

我使用 IntellJ Ultimate，但运行 Mockito 测试类时遇到问题。

如果我使用这样的类

import org.junit.jupiter.api.Test;

class FactoryTest {
    @Test
    void createEntry() {
    }

}

我可以直接“运行”这门课。

如果我有这个:

import static org.mockito.Mockito.when;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.runners.MockitoJUnitRunner;

// @RunWith attaches a runner with the test class to initialize the test data
@RunWith(MockitoJUnitRunner.class)
public class MathApplicationTester {

   //@InjectMocks annotation is used to create and inject the mock object
   @InjectMocks 
   MathApplication mathApplication = new MathApplication();

   //@Mock annotation is used to create the mock object to be injected
   @Mock
   CalculatorService calcService;

   @Test
   public void testAdd(){
      //add the behavior of calc service to add two numbers
      when(calcService.add(10.0,20.0)).thenReturn(30.00);

      //test the add functionality
      Assert.assertEquals(mathApplication.add(10.0, 20.0),30.0,0);
   }
}

我必须之前创建另一个类并运行它，这对我来说似乎不正确，因为在该教程中没有任何关于启动测试的 exlucisv 类的内容 http://www.vogella.com/tutorials/Mockito/article.html#testing-with-mock-objects

    public class TestRunner {
    public static void main(String[] args) {
        Result result = JUnitCore.runClasses(MathApplicationTester.class);

        for (Failure failure : result.getFailures()) {
            System.out.println(failure.toString());
        }

        System.out.println(result.wasSuccessful());
    }
}

Answer 1

MockitoJUnitRunner 是 already deprecated 。

摆脱它之后，您可以使用 @Before 带注释的方法初始化您的模拟:

@Before
public void setup() {
    MockitoAnnotations.initMocks(this);
}
