如何使用Mockito和Spring Boot使用okhttp编写单元测试

<dependency>
    <groupId>org.mockito</groupId>
    <artifactId>mockito-core</artifactId>
    <version>2.28.2</version>
    <scope>test</scope>

<dependency>
    <groupId>com.squareup.okhttp3</groupId>
    <artifactId>okhttp</artifactId>
    <version>3.14.1</version>
</dependency>

@RunWith(MockitoJUnitRunner.class)
public class MyServiceTest {
    
    @InjectMocks
    private MyService myService;
    
    @Mock
    private OkHttpClient httpClient;
    
    // 测试方法
    @Test
    public void testSomething() throws Exception {
        // 模拟OkHttp的响应
        ResponseBody responseBody = ResponseBody.create(MediaType.parse("application/json"), "mock response");
        Response response = new Response.Builder()
                .request(new Request.Builder().url("http://example.com").build())
                .protocol(Protocol.HTTP_1_1)
                .code(200)
                .body(responseBody)
                .build();
        when(httpClient.newCall(any(Request.class))).thenReturn(new MockCall(response));
        
        // 调用MyService中的方法，传递Mockito模拟的HttpClient
        String result = myService.doSomething();
        
        // 验证结果
        assertEquals("expected result", result);
    }
}
