关于触发link 

可以通过文本 title属性，和id属性］ 

 <a href="/signup" title="Sign up" id="signup_link">Click here to
   join!</a>

  click_link "Click here to join!" # substring text 

 click_link /join/i               # regexp text
 click_link "Sign up"             # substring title
 click_link /sign.*up/i           # regexp title
 click_link /signup.*link/i       # regexp id
 click_link "signup_link"         # exact id

webrat的源码定义 

 def click_link(text_or_title_or_id, options = {})
   find_link(text_or_title_or_id).click(options)
 end

而表单的输入框，可以通过id name属性或者label的inner text属性定位，例子如下： 

输入框包括text fields, password fields和text areas 

 

 #<label for="user[email]">Enter your Email</label><input type="text"
   name="user[email]" id="user_name">
   fill_in "user_email", :with => "good@example"      # exact id
   fill_in /user.*email/, :with => "good@example"     # regexp id
   fill_in "user[email]", :with => "good@example"     # substring name
   fill_in /user[.*mail.*]/, :with => "good@example"  # substring name
   fill_in "Email", :with => "[email protected]"       # substring label text
   fill_in /enter your email/i, :with => "[email protected]" # regexp label text

对于隐藏字段的设定 

 # Hidden fields can be set
 set_hidden_field 'user[l337_hax0r]', :to => 'true'

下拉菜单可以通过文本，name属性，label text属性来选中 

 # Select options can be 'selected' by inner text (an exact String or a Regexp
 to match). It can optionally be selected from a particular select field, using
 the usual id, name, or label text.
 select "Free account"
 select "Free account", :from => "Account Types"
 select "Free account", :from => "user[account_type]"
 select "Free account", :from => "user_account_type"

操作多选框 

 # Check boxes can be 'checked' and 'unchecked'
 check 'Remember me'
 uncheck 'Remember me'

操作单选框 

 # Radio buttons can be choosen, using the usual label text, name, or id.
 choose "Yes"

 click_button "Register"

  # check for text in the body of html tags
  # can be a string or regexp
 assert_contain("BURNINATOR")
 assert_contain(/trogdor/i)
 assert_not_contain("peasants")

 # check for a css3 selector
 assert_have_selector 'div.pagination'
 assert_have_no_selector 'form input#name'

判定页面是否有文字 

 # check for text in the body of html tags
 # can be a string or regexp
 # Matchers are verbs used with auxillary verbs should, should_not, etc.
 response.should contain("BURNINATOR")
 response.should contain(/trogdor/i)
 response.should_not contain("peasants")

 # check for a css3 selector
 response.should have_selector('div.pagination')
 response.should_not have_selector('form input#name')

在范围内的界定， 老猪 上文已经提到selenium不支持 

 # selectors syntax is defined here: http://www.w3.org/TR/css3-selectors/
 within 'div.pagination' do |scope|
   scope.click_link "1"
 end

 within '.shows' do |scope|
   scope.should contain("NFL")
   # unfortunately, assertions don't support this currently
 end

 within 'form[name="search"] select[name="type"]' do |scope|
   scope.should have_selector 'option[value="blah"]'
   scope.should have_selector 'option[value="gah"]'
   scope.should have_selector 'option[value="eep"]'
   scope.should have_selector 'input:only-of-type'
   scope.should have_selector 'input[name="query"]'
   scope.should have_selector 'input[type="text"]'
 end
