您好我正在编写我的函数的单元测试用例。如果请求成功，则此函数返回json响应，否则返回错误。
describe("Operations", async () => {
it("user info", async () => {
let accessToken = 'dfsf;
const result = await authConnectors.getUser(accessToken);
});
});
如何在nodejs中使用chai断言http错误和响应？

使用expect和should，您可以按以下方式进行测试：
describe('Testing https responses', () => {
it("user info", async (done) => {
.... request here...
.catch((err) => {
err.response.should.have.status(404);
err.response.body.should.have.property('error');
err.response.body.error.should.eql('User could not be found');
done()
});
})
it('testing using expect', (done) => {
request.get('http://localhost:8000', function (err, res, body) {
expect(res.statusCode).to.equal(400);
expect(res).to.have.property('body');
expect(res.body).to.equal('wrong header');
done();
});
});
})
这些测试是异步的，所以他们需要在
结束时解决这个问题done()
.property（name [，val [，msg]]）
断言目标具有具有给定键名的属性。
expect({a: 1}).to.have.property('a');

您可以使用try-catch并处理错误=）
it("user info", async () => {
try{
let accessToken = 'dfsf;
const result = await authConnectors.getUser(accessToken);
} catch(e) {
// check error
}
});
