json接口:
http://apis.juhe.cn/simpleWeather/query?city=武汉&key=******
key值自己在聚合数据网站上获得,填写到这里就可以用
此案例中设置的断言:
pm.test('状态码是200',function(){
pm.response.to.have.status(200)
}); //断言状态码是200
pm.test('响应时间小于500ms',function(){
pm.expect(pm.response.responseTime).to.be.below(500);
});//响应时间小于500ms
var jsonData =JSON.parse(responseBody);
tests['body中的reason结果'] = jsonData.reason ==='查询成功!' //验证Body里面的内容
tests['body中的city是否正确'] = jsonData.result.city ==='武汉' //验证body中的城市是否正确
//验证是不是从当天开始的
pm.test('验证body中的第一天天气是否为当天的',function(){
var jsonData = pm.response.json();
pm.expect(jsonData.result.future[0].date) ==='2020-06-15' //后面验证的需要改此处的时间
});

// These statements should be wrapped in a try-catch block if the data is coming from an unknown source.
var array = JSON.parse(pm.environment.get("array"));
var obj = JSON.parse(pm.environment.get("obj"));
|
Clear an environment variable (清除一个环境变量)
|
1
