我有一個簡單的HTML頁面(ratings.html),我試圖使用HtmlUnit進行測試。當我在瀏覽器中加載它並手動完成時,我正在測試的操作就起作用了。但是,當我嘗試使用HtmlUnit進行測試時,似乎太多調用getElementById(或getInputByName)會導致頁面上的JavaScript重新初始化。HtmlUnit的HtmlPage.getElementById似乎在多次調用後重新初始化JavaScript
在AddRating.scala測試中,前兩次調用page.addRating工作,但第三次調用失敗,因爲它無法在頁面上找到'rating3'元素。經過大量調試後,我發現ratingCount
由於某種原因重置爲0。
看到我下面的評論(// ******
部分之間),看看問題所在的地方。
有沒有其他人遇到過這種行爲或對如何處理它有任何建議?謝謝!

RatingsPage.scala(斯卡拉接口HTML頁面):
package portal
import com.gargoylesoftware.htmlunit.WebClient
import com.gargoylesoftware.htmlunit.html._
import infrastructure.SuperHtmlUnitConversions._
import infrastructure.WaitFor
class RatingsPage(page: HtmlPage)
{
val newRatingForm: HtmlForm = page.getFormByName("new-rating")
var ratingCount = 0
def submit(): RatingsPage =
{
val page = newRatingForm.getButtonByName("submit-button").click[HtmlPage]()
ratingCount = 0
new RatingsPage(page)
}
def addRating(rating: String)
{
page.getElementById("add-rating").click()
ratingCount += 1
newRatingForm.getInputByName("rating" + ratingCount).asInstanceOf[HtmlInput].setValueAttribute(rating)
}
def asText(): String = page.asText
def asXml(): String = page.asXml
}
AddRating.scala (斯卡拉HtmlUnit測試失敗):
package portal
import java.util.Date
import org.scalatest.FunSuite
import org.scalatest.junit.JUnitRunner
import org.junit.runner.RunWith
import org.scalatest.matchers.ShouldMatchers

class AddRating extends FunSuite with ShouldMatchers
{
test("add ratings")
{
val client = new WebClient()
val index = new PortalIndexPage(client)
var page = index.goToRatingsPage()
page.addRating("Buy") // WORKS
page.addRating("Sell") // WORKS
// *********
page.addRating("Sell") // FAILS! Can't find element with "rating3" name!
// *********
page = page.submit()
WaitFor("rating to show up",()=>page.asXml.contains("Sell"))
page.asText should include ("Buy")
client.closeAllWindows()
}
}
這會如何影響'ratingCount'變量的重新初始化? – 2011-06-16 17:41:26
