Watire 与 XPath

XPath在watir自动化测试中的应用

http://www.51testing.com/?170805/action_viewspace_itemid_88589.html

ie.element_by_xpath("//area[contains(@href , 'PieChart.html')]/").click

<table>

<tr>

   <td><img src="1.jpg">First Image</td>

</tr>

</table>

<table>

<tr>

   <td><img src="2.jpg">Second Image</td>

</tr>

</table>

<table>

<tr>

   <td><img src="3.jpg">Third Image</td>

</tr>

</table>



若不用xpath,实现只点击3.jpg的方法：



ie.tables.each do |t|                     # since you don't have ID's, look at every table

for i in 1..t.row_count                 # for every row in this table

   t[i].each do |cell|                   # for every column in this row, look at its contents

     if cell.image(:src, /3.jpg/).exists? # if true, this is your cell

       puts cell.text

     end

   end

end

end



但是用xpath就是非常简练：



ie.cell(:xpath, "//img[@src='3.jpg']/").click()
