I click a link and a new IE window comes up, and forget to attach the new IE window, so watir and me are looking for elements on different windows.

ie77.refresh

Yesterday an idea came into my mind, and I found a solution, following is the code:

ie77.frame(:id, /Editor/).document.body.innertext = “good and better”

puts “to close a certain previous browser”
Watir::IE.attach(:title, /google/).close
puts “to close a certain previous browser”
Watir::IE.attach(:title, /Internet/).close
puts “to close a certain previous browser”
Watir::IE.attach(:title, /Internet/).close

but when 2 or more watir programs run together, they stalled there. I don’t know the reason, so I tried the following code which worked ok:

sleep 1
puts “to close all the other browsers”
ie77.close_others
sleep 1
puts “to close current browser”
ie77.close

require ‘watir’
include Watir

# Initialize the text to be submitted to a bbs
conts = []
File.open(‘goodword.txt’) do |f|
f.each_line{|l| conts << l}
end
#Initialize the advertising text to be appended
advs = []
File.open(‘adv.txt’) do |f|
f.each_line{|l| advs << l}
end
———
ie22.text_field(:name, ‘co’).set(conts[rand(conts.size)])
ie22.text_field(:name, ‘co’).append(“\n”)
ie22.text_field(:name, ‘co’).append(“\n”)
ie22.text_field(:name, ‘co’).append(“\n”)
ie22.text_field(:name, ‘co’).append(“\n”)
ie22.text_field(:name, ‘co’).append(advs[rand(advs.size)])

—–

“\n”     means change to a new line.

require ‘watir’
include Watir

jinan = “http://homemsg.focus.cn/msgview/607/48996344.html”

ie21 = IE.new
ie21.goto jinanba

puts ie21.table(:index => 9, :class => /p9/).text

#puts ie21.table(:index => 11, :class => /p9/).html

The following is the code to use firewatir for Page scraping, the reson to use firewatir is that the watir will wait for the page load:

require ‘firewatir’
include FireWatir

jinanba = “http://homemsg.focus.cn/msgview/607/48996344.html”

ie21 = Firefox.new
ie21.goto jinanba

fout = File.new(“test.txt”, “w”)
fout.puts ie21.table(:index , 16).html
fout.close

1. Open an editor
2. take the .rb as your file extention
3. put the “require ‘watir’” into the first line
4.打开浏览器并转到要测试的应用
5.与之交互并设计你的testcase
6.在测试脚本中使用Watir方法
7.验证结果

Interacting With a Web Page
When Watir is used as a test script, the interaction with a web page is realized by submitting message to the element on the web page:

ie.text_field(:name , “q”).set(”bluescorpio”)
ie.button(:value , “Click Me”).click

Watir Syntax
1.使用Watir工具，需要在脚本中加上
require ‘watir’

2.创建一个IE的测试实例
ie = Watir::IE.new
或者在创建的同时直接转到页面
ie = Watir::IE.start(”http://mytestsite”)
Watir使用start方法同时创建一个浏览器实例并转到一个页面。

3. Web navigation
ie.goto(”http://mytestsite”)

4.操纵Web页面对象
4.1超链接
4.1.1使用Text属性点击超链接
ie.link(:text , “Pickaxe”).click
对应的HTML代码为：
<a href=”http://pragmaticprogrammer.com/titles/ruby/”>Pickaxe</a>
4.1.2使用URL属性点击超链接
ie.link(:url , “http://pragmaticprogrammer.com/titles/ruby/”).click
对应的HTML代码为：
<a href=”http://pragmaticprogrammer.com/titles/ruby/”>Test Site</a>

4.2复选框
4.2.1使用name属性设置复选框
ie.checkbox(:name, “checkme”).set
4.2.2使用name属性清除复选框
ie.checkbox(:name, “checkme”).clear
4.2.3使用name和value属性设置复选框
ie.checkbox(:name, “checkme”, “1″).set
4.2.4使用name和value属性清除复选框
ie.checkbox(:name, “checkme”, “1″).clear
对应的HTML代码为：

<input maxlength=”67108863″ name=”checkme” size=”20″ type=”checkbox” value=”1″ />

4.3单选框
4.3.1使用name属性设置单选框
ie.radio(:name, “clickme”).set
4.3.2使用name属性清除单选框
ie.radio(:name, “clickme”).clear
4.3.3使用name和id属性设置单选框
ie.radio(:name, “clickme”, “1″).set
4.3.4使用name和id属性清除单选框
ie.radio(:name, “clickme”, “1″).clear
对应的HTML代码为：

<input id=”1″ maxlength=”67108863″ name=”clickme” size=”20″ type=”radio” value=”on” />

4.4下拉框
4.4.1使用name属性和值来设置下拉框
ie.select_list( :name , “selectme”).select(”is fun”)
4.4.2使用name属性和值来清除下拉框
ie.select_list( :name , “selectme”).clearSelection
对应的HTML代码为：

<select name=”selectme”> <option selected=”65535″></option><option>Web Testing</option><option>in Ruby</option><option>is fun</option></select>

4.5在Web页面中输入数据

4.5.1使用文本输入框的那么属性设置输入内容
ie.text_field(:name, “typeinme”).set(”Watir World”)
4.5.2清空文本输入框
ie.text_field(:name, “typeinme”).clear
对应的HTML代码为：

<input maxlength=”67108863″ name=”typeinme” size=”20″ type=”text” />

4.6从Web页面上提交数据
4.6.1按钮
4.6.1.1通过值或标题属性点击按钮
ie.button(:value, “Click Me”).click
4.6.1.2通过name属性点击按钮
ie.button(:name, “clickme”).click

对应的HTML代码为：

<input maxlength=”67108863″ name=”clickme” size=”20″ type=”button” value=”Click Me” />

4.6.2 Forms
4.6.2.1 buttons in the forms
using value or title      ie.button(:value, “Submit”).click
对应的HTML代码为：

<form action=”submit” accept-charset=”UNKNOWN” enctype=”application/x-www-form-urlencoded” method=”post”> <input maxlength=”67108863″ size=”20″ type=”submit” value=”Submit” /></form>4.6.2.2表单中的图片按钮
使用那么属性
ie.button(:name, “doit”).click
following are the corresponding HTML codes：

<form action=”submit” accept-charset=”UNKNOWN” enctype=”application/x-www-form-urlencoded” method=”post”> <input maxlength=”67108863″ name=”doit” size=”20″ src=”http://www.gnpc.cn/wp-admin/images/doit.gif” type=”image” /></form>4.6.2.3没有按钮的表单
Watir can submit a form by identifying it by its name, action and method attributes.
可以通过name、action以及method属性来提交表单
ie.form(:name, “loginform”).submit
ie.form(:action, “login”).submit
对应的HTML代码为：

<form action=”login” accept-charset=”UNKNOWN” enctype=”application/x-www-form-urlencoded” method=”get”> <input maxlength=”67108863″ name=”username” size=”20″ type=”text” /></form>4.6.3框架
ie.show_frames可以打印出当前页面框架的数量和名称
Watir允许通过名称属性来访问框架，如ie.frame(”menu”)
如果要访问menu框架中的一个超链接，可以ie.frame(”menu”).link(:text, “Click Menu Item”).click

4.6.4 embedded frame
ie.frame(”frame1″).frame(:name, “nested_frame”)

4.6.5新窗口
一些Web应用会弹出新窗口或打开一个新窗口，可以使用attach方法来访问并控制新窗口。通过标示新窗口的URL或者title来访问。
ie2 = Watir::IE.attach(:url, ‘http://mytestsite’)
ie3 = Watir::IE.attach(:title, ‘Test New Window’)
Regx is also an alternative    ie4 = Watir::IE.attach(:title, /Test New/)
注意：不要把新窗口分配到你的ie变量，最好给新窗口一个不同的名字

5. verify the test result
比较好的方法是在测试案例中假如验证点
5.1对象存在
使用Watir方法contains_text
ie.contains_text(”Reached test verification point.”)

if ie.contains_text(”Reached test verification point.”)
puts: “Test passed. Page contains the text: Reached test verification point.”
else
puts: “Test failed! Page didn’t contain text: Reached test verification point.”
end

5.2 using test::unit Assertions
5.2.1需要test::unit
require ‘test/unit’

5.2.2创建测试实例
class TC_myTest &lt; Test::Unit::TestCase
…fill in Test Case methods here…
end

5.2.3创建测试用例方法
在测试类中，需要声明象下面的方法：
def test_myTestCase
fill in method body with Watir code and assertion here
end

方法必须以test开头，ruby会随机运行测试案例，如果需要顺序执行，需要在test后加上字母或数字来强迫它顺序执行，比如“test_a_mytest”

定义测试方法的类：
class TC_myTest &lt; Test::Unit::TestCase
def test_ myTestCase
Watir code and assertion here…
end
def test_anotherTestCase
Watir code and assertion here…
end
def test_aTestCase
Watir code and assertion here…
end
end

5.2.4 Using Assertions
Watir通过在一个asert覆写Watir方法支持assertions。
assert(ie.contains_text(”Reached test verification point.”))

5.2.5Setup and Teardown
def setup
fill in code that will run before every test case here…
end
def teardown
fill in code that will run after every test case here…
end

6.Tips and Tricks
Running Tests With the Browser Not Visible
Run the tests with a “-b” option if you don’t want the browser to be visible. ex. myTest.rb -b
