如何对具有对象RequestParam的控制器方法进行单元测试？

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ExampleController {

    @GetMapping("/example")
    public String exampleMethod(@RequestParam String param) {
        return "Received parameter: " + param;
    }
}

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.test.web.servlet.MockMvc;

@WebMvcTest(ExampleController.class)
public class ExampleControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testExampleMethod() throws Exception {
        mockMvc.perform(get("/example")
                .param("param", "testValue"))
                .andExpect(status().isOk())
                .andExpect(content().string("Received parameter: testValue"));
    }
}
