我正在使用Jasmine进行一些测试,尽管这通常可以应用于基于浏览器的javascript单元测试.

我有一个功能,在某些条件下,用户将用户重定向到不同的页面window.location.assign.问题是,如果达到此行,页面将被重定向.在这种情况下,由于它被重定向到'/',页面重新加载,所有测试再次运行.我该怎么做才能测试函数是否到达重定向的行,而不重定向？

DOM的实现或模拟是纯粹的javascript吗？

• 有env.js,但这需要Rhino.
• 有jsdom,但这需要Node.

是否有适用于大多数任何javascript解释器的解决方案,例如v8,而不是绑定到任何特定的解释器或引擎？也就是说,JS中是否有任何DOM实现,没有任何设置或垫片可以放入javascript解释器并运行？

我怎么能在jQuery中找到哪些事件与特定元素的实时绑定？

假设我有一个函数,randomFunction它从函数数组中返回一个随机函数.如何找到哪个函数绑定到某个元素？

var arrayOfFunctions = []; //a whole bunch of functions
function randomFunction(array){}; //returns one of those functions
$('#certain_element').live('click', randomFunction(arrayOfFunctions));

与livefor 绑定的函数对应的数组的索引是什么$('#certain_element')？

这是半编程,半数学问题.

我有一些盒子,代表四个角点.它们是真正的矩形,是两组平行线的交点,每组中的每一行都与另一组中的两条直线成直角(我们很清楚.)

对于任何一组n个框,我怎样才能有效地计算移动它们的位置(最小距离),以便它们不会相互重叠？

我在这里用javascript工作.这是数据:

//an array of indefinite length of boxes
//boxes represented as arrays of four points
//points represented as arrays of two things, an x and a y, measured in
//pixels from the upper left corner

为清晰起见,这个小提琴显示了半透明地画在画布上的方框.

我有一个关于在黄瓜中使用硒的问题.

这里是黄瓜的特点:

@selenium @javascript
  Scenario: Create forum
    Given I have a site named "hairclub" and I logged in as admin
    When I am on the "admin" page

要运行,我使用此命令:

cucumber features/forum.feature

它工作正常; 它会打开浏览器(如您所见@selenium @javascript tag).一切都很好看.

我想运行相同的黄瓜脚本但不打开浏览器; 我想如果场景增长,浏览器运行需要一段时间.我希望能够在浏览器打开的情况下运行,也不需要打开浏览器.有没有命令我可以从终端传递给覆盖@selenium @javascript？

在控制器方法中,如何渲染模板和布局？

像这样:

def new
  render :template => 'devise/invitations/new', :layout => 'application_unauthorized2_t2' 
end

有没有办法在rspec中使用隐式主题正确测试异常提升？

例如,这失败了:

describe 'test' do
  subject {raise 'an exception'}
  it {should raise_exception}
end

但这传递了:

describe 'test' do
  it "should raise an exception" do
    lambda{raise 'an exception'}.should raise_exception
  end
end

为什么是这样？

我在sql表中创建了一个write func odbc list记录文件：

[R]

dsn=connector

write=INSERT INTO ast_records (filename,caller,callee,dtime) VALUES
('${ARG1}','${ARG2}','${ARG3}','${ARG4}')

prefix=M

并将其设置在拨号计划中：

exten => _0X.,n,Set(
M_R(${MIXMONITOR_FILENAME}\,${CUSER}\,${EXTEN}\,${DTIME})= )

当我执行它时，我收到一个错误：ast_func_write: M_R 函数未注册：
