我正在开发测试套件，现在大部分时间都在通过，但并非总是如此！这是 5 个非常基本的测试（与索引相关的测试）的示例。在这些测试中，最后两个（断言 url 测试）随机通过（有时都失败，有时都成功，有时一个有效，另一个失败）。即使在调试模式下，我也找不到他们通过/失败重新产生工作条件的方式的任何模式。我的第一个虽然是竞争条件，但似乎不是，因为即使使用 wait() 计时器，问题仍然存在。所以我虽然，也许我对 casper 的测试/理解的实现是不正确的。
随时向我提供有关此测试实施的反馈，或任何允许最后两个测试以 100% 的时间通过的潜在改进。当前的 MMVC 框架是主干，测试在运行之前进行编译，如果需要，我可以提供测试的编译（js）版本。
测试：
{t} = require '../helpers'
{baseUrl} = require '../config'
mouse = require('mouse').create(casper)
casper.options.loadImages = false
casper.options.verbose = true
casper.options.logLevel = 'debug'
casper.test.begin 'Home page loads correctly', 3, (test) ->
casper.start "#{baseUrl}page/log-out"
casper.thenOpen baseUrl, ->
test.assertHttpStatus 200, 'Status code is 200'
casper.then ->
test.assertTitle t('siteName'), "Title is '#{t 'siteName'}'"
casper.then ->
test.assertTextExists t('home:featureWhatIsBitcoinTitle'), 'Page body contains intro text'
casper.run ->
test.done()
casper.test.begin 'Home page links to sign up page', 1, (test) ->
casper.start "#{baseUrl}page/log-out"
casper.thenOpen baseUrl, ->
@evaluate -> document.querySelector('#signup').click()
casper.then ->
test.assertUrlMatch /\/page\/sign-up/, 'Url matches sign up page'
casper.run ->
test.done()
casper.test.begin 'Home page links to log in page', 1, (test) ->
casper.start "#{baseUrl}page/log-out"
casper.thenOpen baseUrl, ->
@evaluate -> document.querySelector('a[href="/page/log-in"]').click()
casper.then ->
test.assertUrlMatch /\/page\/log-in/, 'Url matches log in page'
casper.run ->
test.done()
