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
