Question

我正在尝试使用mocha，zombie和chai进行跨页测试，遵循使用Node＆amp;表达

版本信息：macOS 10.12.2，mocha 3.5.0，chai 3.2.0，zombie 5.0.5，node v7.4.0。

QA JS代码：

var Browser = require("zombie");
var assert = require("chai").assert;

var browser;

suite("Cross-Page Tests", function () {
    setup(function () {
        browser = new Browser();
    })
    // Test (1
    test("Requesting Group-Rate from the river page, should populate the referrer field", function (done) {
        var referrer = "http://localhost:3000/river";
        browser.visit(referrer, function () {
            browser.clickLink(".requestGroupRate", function () {
                assert(browser.field("referrer").value === referrer);
                done();
            })
        })
    })
    // Test (2
    test("Requesting Group-Rate from the coast page, should populate the referrer field", function (done) {
        var referrer = "http://localhost:3000/coast";
        browser.visit(referrer, function () {
            browser.clickLink(".requestGroupRate", function () {
                assert(browser.field("referrer").value === referrer);
                done();
            })
        })
    })
    // Test (3
    test("Visit request group rate page directly, should have an empty field.", function (done) {
            browser.visit("http://localhost:3000/request-group-rate", function () {
                assert(browser.field("referrer").value === "");
                done();
            })
        })
})

在终端中显示的内容（在mocha -u tdd -R spec qa/tests-crosspage.js 2>/dev/null之后）：

...

  1) Cross-Page Tests Requesting Group-Rate from the river page, should populate the referrer field:
     Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.


  2) Cross-Page Tests Requesting Group-Rate from the coast page, should populate the referrer field:
     Uncaught AssertionError: No link matching '.requestGroupRate'
      at Browser.clickLink (node_modules/zombie/lib/index.js:695:7)
      at qa/tests-crosspage.js:28:21
      at Browser.done (node_modules/zombie/lib/eventloop.js:589:11)
      at node_modules/zombie/lib/document.js:819:13
      at process._tickCallback (internal/process/next_tick.js:103:7)

  3) Cross-Page Tests Visit request group rate page directly, should have an empty field.:
     Uncaught AssertionError: No link matching '.requestGroupRate'
      at Browser.clickLink (node_modules/zombie/lib/index.js:695:7)
      at qa/tests-crosspage.js:18:21
      at EventLoop.done (node_modules/zombie/lib/eventloop.js:589:11)
      at Immediate.<anonymous> (node_modules/zombie/lib/eventloop.js:688:71)

让我困惑的是什么： 1）我在每次测试中都调用done()，但为什么测试1仍然超时？ 2）在测试3中，没有与链接匹配'.requestGroupRate'相关的代码，那么它来自哪里？

注意： 我手动检查了localhost:3000\river页面。有一个<a>类，requestGroupRate。海岸页面不存在，因此测试2是必须失败的测试。

测试必须从

改变

assert(browser.field('referrer').value === 'referrer');

到

assert(browser.field('referrer').value === ' ');

使用mocha，zombie和chai的未知测试失败案例
