Spring mvc :使用MockMultipartFIle和其他表单数据对控制器进行单元测试

import org.junit.jupiter.api.Test;
import org.springframework.mock.web.MockMultipartFile;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpServletResponse;
import org.springframework.web.multipart.MultipartFile;

import static org.junit.jupiter.api.Assertions.assertEquals;

class MyControllerTest {

    @Test
    void testUploadFile() throws Exception {
        // 创建一个模拟的文件
        byte[] fileContent = "Hello, World!".getBytes();
        MultipartFile file = new MockMultipartFile("file", "test.txt", "text/plain", fileContent);

        // 创建一个模拟的请求对象
        MockHttpServletRequest request = new MockHttpServletRequest();
        request.setMethod("POST");
        request.addFile(file);

        // 设置其他表单数据
        request.setParameter("name", "John Doe");

        // 创建一个模拟的响应对象
        MockHttpServletResponse response = new MockHttpServletResponse();

        // 创建控制器对象并调用方法
        MyController controller = new MyController();
        controller.uploadFile(request, response);

        // 验证控制器的行为和输出结果
        assertEquals(200, response.getStatus());
        assertEquals("File uploaded successfully", response.getContentAsString());
    }
