我对Ruby非常陌生并且使用Watir开发脚本以进行验收测试,而且我陷入了一种我甚至不确定是否有可能退出的问题。
我有一个运行的小脚本,基本上会查看下拉列表,将所有下拉项存储到一个全局变量中,然后迭代并运行其他一些函数。
当我尝试在为每个下拉项运行所有函数之后刷新浏览器然后尝试迭代到下一个下拉项并执行相同的函数直到所有下拉项都完成时,会出现问题。
$browser = Watir::Browser.new :chrome
$wait = Watir::Wait
def wait_while_loading(what)
lightbox = $browser.div(:class , 'lightbox')
begin
# Capture load start
start = Time.now
$wait.until { lightbox.present? }
$wait.until { !lightbox.present? }
# Capture load end
finish = Time.now
load_time = (finish - start).to_s
rescue => e
print e.backtrace.join("\n")
#log_error('Failed while loading ' + what + '.')
end
end
def cycle_all_views
$views = []
$current_view
$view_dropdown = $browser.div(:id, 'views-dropdown')
$views = $browser.div(:class, 'dropdown-views').div(:class, 'dropdown-menu--footer').ul(:class, 'dropdown-menu').divs(:class, 'dropdown-menu-item')
start_on_view = 10
begin
$views.drop(start_on_view).each_with_index do |view, i|
$view_dropdown.click
$current_view = view.text
index = i.to_s
safe_name = sanitize($current_view)
view.click
wait_while_loading($current_view)
$browser.refresh
wait_while_loading('Refreshing Page...')
end
rescue => e
#log_error('Failed to load view ' + $current_view)
end
end
触发$browser.refresh
后,在迭代到下一个$views_dropdown
后点击view
,我会收到一条错误消息,指出no implicit conversion of nil into String
假设在尝试$current_view = view.text

1}}。页面刷新后是否会丢失对变量的所有赋值?如果是这样,有没有办法保留它们?
如果有人也能指出我调试Watir脚本的更好方法,我很想知道如何让我的生活更轻松。

这是一个展示这个问题的例子(在信用到期时给予信任 - 识别出titusfortner):
require 'watir-webdriver'
b = Watir::Browser.new :chrome
b.goto('http://www.iana.org/domains/reserved')
first_link_from_divs = b.div(id: "sidebar_left").links.first
first_link_from_divs.text #=> Overview
first_link_from_divs.exists? #=> true
just_a_link = b.link(text: "Overview")
just_a_link.text #=> Overview
just_a_link.exists? #=> true
b.refresh
first_link_from_divs.exists? #=> false
just_a_link.exists? #=> true
