我正在为Node.js应用程序运行以下集成测试。第一个API已经存在,而第二个API不存在:
'use strict';
var app = require('../..');
import request from 'supertest';
describe('Planes API:', function() {
describe('GET /api/planes/:name', function() {
it('should contain a list of alive cells', function() {
request(app)
.get('/api/planes/a-block-and-bar')
.expect(200)
.expect('Content-Type', /json/)
.end((err, res) => {
console.log("getting here? 1");
var plane = res.body;
plane.aliveCells.length.should.equal(3);
});
});
it('should load a specific generation', function() {
request(app)
.get('/api/planes/a-block-and-bar/generation/1')
.expect(200)
.expect('Content-Type', /json/)
.end((err, res) => {
console.log("getting here? 2");
res.status.should.equal(200);
});
});
});
});
然而,输出是:

因此测试结果是假阴性。输出显示404由API返回,但我不能通过使用.expect()
指定200来使其失败。
为什么测试没有失败?请注意,永远不会打印getting here? 2
。
答案 0 :(得分:1)
我会试试
it('should load a specific generation', function(done) {
然后在done()
方法中调用end
。如果从未打印第2个日志,则此异步测试应产生超时错误。我不熟悉supertest,但似乎在404
的情况下它不会触发。也许存在错误事件处理程序?
