Spring [spring-test] When test methods have parameters, it has a error: No ParameterResolver registered for parameter.

package com.example.demo;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit.jupiter.SpringExtension;
@SpringBootTest

@ExtendWith(SpringExtension.class)
class DemoApplicationTests {

    @Test
    void contextLoads(String string) {
    }
}

The code is very simple. But when I test the code, it show error like:

org.junit.jupiter.api.extension.ParameterResolutionException: No ParameterResolver registered for parameter [java.lang.String string] in method [void com.example.demo.DemoApplicationTests.contextLoads(java.lang.String)].

You can see the code:

SpringExtension implements ParameterResolver

Is there something wrong?
