尝试将新元素插入到我的mongoDB数据库中,当我使用“npm run test”终端时,它给了我这个错误:
Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure
"done()" is called; if returning a Promise, ensure it resolves.
这是我将元素保存到我的数据库的代码:
const mocha = require('mocha');
const assert = require('assert');
const PPB = require('../Models/Pingpongballs');
describe('Saving records', function() {
it('Saves record to db', function(done) {
var ppball = new PPB ({
amount: 5
});
ppball.save().then(function() {
assert(ppball.isNew === false);
done();
});
});
});

在mocha中,对于异步测试,您可以调用[OutputCache(NoStore = true, Duration = 0)]
回调或返回承诺。您收到此错误,因为您的测试失败了,并且您没有done
阻止调用catch
并出错:
done
