如何在 Kubernetes 中测试大规模 Java 函数

import java.util.HashMap;
import java.util.Map;

public class SimpleFunction {

    public Map<String, String> handleRequest(Map<String, String> request) {
        // 业务逻辑
        Map<String, String> result = new HashMap<>();
        result.put("message", "Hello, world!");
        return result;
    }
}

import org.junit.jupiter.api.Test;

class SimpleFunctionTest {

    @Test
    void testHandleRequest() {
        SimpleFunction function = new SimpleFunction();
        Map<String, String> request = new HashMap<>();
        Map<String, String> result = function.handleRequest(request);
        assertEquals("Hello, world!", result.get("message"));
    }
}
