用geb /硒迭代页面

Question

我想遍历页面列表以验证每个页面的内容

[我想通过GEB进行迭代。https://github.com/trending然后访问趋势中的每一页并验证标题，然后继续下一页。

但是错误org.openqa.selenium.StaleElementReferenceException: stale element reference: element is not attached to the page document困扰着我。

@Grapes([
    @Grab('org.gebish:geb-core:3.3'),
    @Grab('org.seleniumhq.selenium:selenium-support:3.141.59'),
    @Grab('org.seleniumhq.selenium:selenium-chrome-driver:3.141.59'),

import geb.navigator.Navigator

import groovy.transform.TypeChecked
import org.openqa.selenium.WebDriver
import org.openqa.selenium.chrome.ChromeDriver

import geb.Page

import static geb.Browser.drive

System.setProperty("webdriver.chrome.driver","/Users/v/Downloads/chromedriver")
def chromeDriver = new ChromeDriver()
println chromeDriver.getSessionId()
drive(driver: chromeDriver, baseUrl: "https://github.com") { 
    to ProviderListPage
    Navigator pages = list()
    pages.each {
        to ProviderPage, it.attr("href").split('/').reverse()[1],it.attr("href").split('/').reverse()[0]
        waitFor { 5 }
        driver.navigate().back()
    }
    driver.quit()
}

class ProviderListPage extends Page {
    static url = "/trending"

    static content = {
        providers { $(".h3 a") }
    }
    def list() {
        return providers
    }

}
class ProviderPage extends Page {
    static content = {
        heading { $(".h3 a").text() }
    }
    def waitForHeading() {
        waitFor { assert $(".h3 a") }
    }
}

这是我为所有人复制的示例。仅更改webdriver.chrome.driver。

我确实知道页面从ListPage变为ProviderPage #1，并导致错误：StaleElementReferenceException。但是我不清楚我是如何在页面之间来回导航并翻阅我的页面列表的。 ProviderPage #2

问题是：

• 从概述页面浏览到另一个页面，然后使用“浏览器后退”，即再次加载概述页面（即使可能从浏览器缓存中加载。）>
• 但是您还是从第一次加载概述页面时就开始使用导航器，而是通过each在导航器上进行迭代。这意味着元素已经过时。

相反，您应该在首次打开概述页面时获得在列表上进行迭代所需的所有信息。这还将节省时间，并使“浏览器返回”完全多余。这对我有用：

package de.scrum_master.stackoverflow.q59958656

import geb.spock.GebReportingSpec

class GitHubTrendingIT extends GebReportingSpec {
  def test() {
    given:
    browser.baseUrl = "https://github.com"
    def providerListPage = to ProviderListPage
    report "provider list page"
    providerListPage
      .list()
      .collect {
        def pageInfo = it.attr("href").split('/').reverse()
        [pageInfo[1], pageInfo[0]]
      }
      .each {
        println "trending page = $it"
        to ProviderPage, it[0], it[1]
        report "trending page"
      }

    expect:
    true
  }
}
我将代码包装到Groovy测试类中。如果要从脚本执行代码，只需删除不需要的部分（我从不这样做）。
