瓦杰里的目标页有助于我们以班级的形式重新使用该守则。 利用网页物体特征,我们可以自动进行,而不必重复任何代码,并使该代码能够管理。
在测试时,我们可以为将要测试的每页打上一页。 然后,我们将使用该页标语获取方法和财产。
使用页标的理由——
如果在改动时对该页作任何改动,则不必重写该代码。
避免法典重复。
我们将利用RSpec在瓦伊使用页面目标。 如果你不熟悉RSpec,这里是可供你学习的全套教学课程:
在这里,我们将进行测试。
textbox.html
<html>
<head>
<title>Testing UI using Watir</title>
</head>
<body>
<script type = "text/javascript">
function wsentered() {
console.log("inside wsentered");
var firstname = document.getElementById("firstname");
if (firstname.value != "") {
document.getElementById("displayfirstname").innerHTML =
"The name entered is : " + firstname.value;
document.getElementById("displayfirstname").style.display = "";
}
}
</script>
<span id = "spanfirstname">
Enter First Name :
<input type = "text" id = "firstname" name = "firstname" onchange = "wsentered()" />
</span>
<br/>
<br/>
<span style = "display:none;" id = "displayfirstname"></span>
</body>
</html>
Output
我们现在为上述网页制造一页物体,如下文所示:
pageobjecttest.rb
class InitiapzeBrowser
def initiapze(browser)
@browser = browser
end
end
class TestPage lt; InitiapzeBrowser
def textbox
@textbox = TestTextbox.new(@browser)
end
def close
@browser.screenshot.save usingpageobject.png
@browser.close
end
end # TestPage
class TestTextbox < InitiapzeBrowser
URL = "http://localhost/uitesting/textbox.html"
def open
@browser.goto URL
self
end
def enterdata_as(name)
name_field.set name
name_field.fire_event( onchange )
end
private
def name_field
@browser.text_field(:id > "firstname")
end
end # TestTextbox
界定了三个班级:初始班轮、测试和试验箱。
一旦执行上述守则,你就可以看到产出如下:
