邮差断言

Question

我在练习中有关于断言的问题。

我有这样的响应体:

[
{
"id": 1,
"manufacturer": "Ford",
"model": "Model T",
"build": 1927
},
{
"id": 2,
"manufacturer": "Tesla",
"model": "Model 3",
"build": 2017
},
{
"id": 3,
"manufacturer": "Tesla",
"model": "Cybertruck",
"build": 2019
}
]

我写了test

const response = pm.response.json()

let model;

for (let filter of response) {
if (filter.model === "Model 3") {
//console.log(filter)
model = filter;
}
}
console.log(model)

pm.test("car model is Model 3", function () {
pm.expect(response.model).to.eql("Model 3");
});

不幸的是，我的测试失败了AssertionError: expected undefined to deeply equal 'Model 3'，我试图弄清楚，但不知道为什么这不是通过，因为我的导航到那个模型是正确的。你能告诉我我的代码有什么问题吗?

Answer 1

response.model是undefined，因为response是一个数组。
你可能忘了用model.model代替response.model

pm.test("car model is Model 3", function () {
pm.expect(model.model).to.eql("Model 3");
});
