如何使用groovy断言json文件中的值？

import groovy.json.JsonSlurper
import static org.junit.Assert.assertEquals

def jsonFile = new File("path/to/json/file.json")
def jsonSlurper = new JsonSlurper()
def jsonObject = jsonSlurper.parseText(jsonFile.text)

assertEquals(expectedValue, jsonObject.propertyName)

import groovy.json.JsonSlurper
import static org.junit.Assert.assertEquals

def jsonFile = new File("path/to/json/file.json")
def jsonSlurper = new JsonSlurper()
def jsonObject = jsonSlurper.parseText(jsonFile.text)

assertEquals("John Doe", jsonObject.name)
assertEquals(25, jsonObject.age)
