关于mockito:mockito-总结

1. 如果测试类是A，被测试方法是funcA

@Componentpublic class A {    @Autowired    private B b;    public String funcA(String name) {        return b.getName(name, false);    }}

@Componentpublic class B {    public String getName(String name, boolean flag) {        return name + ":" + flag;    }}

2. 如何定义测试类

import static org.junit.jupiter.api.Assertions.*;import org.junit.Before;import org.junit.jupiter.api.Test;import org.junit.jupiter.api.extension.ExtendWith;import org.mockito.InjectMocks;import org.mockito.Mock;import org.mockito.junit.jupiter.MockitoExtension;import static org.junit.jupiter.api.Assertions.*;import static org.mockito.ArgumentMatchers.anyString;import static org.mockito.ArgumentMatchers.eq;import static org.mockito.BDDMockito.given;import static org.mockito.Mockito.*;@ExtendWith(MockitoExtension.class)class ATest {    @InjectMocks    private A a;    @Mock    private B b;        @Before    public void setUp(){        // 通过反射给属性，常量或者动态变量赋值    }    @Test    public void test() {        String name = a.funcA("name");        assertEquals(name, "name:");        verify(b).getName(anyString(), false);        doCallRealMethod().when(a).funcA(anyString());        given(b.getName(anyString(), eq(false))).willReturn("zhangsan");        assertEquals("zhangsan", "name:");        doThrow(new RuntimeException("error msg")).when(b).getName(anyString(), eq(false));        RuntimeException runtimeException = assertThrows(RuntimeException.class, () -> a.funcA("name"));    }}
