java我是否使用了正确的代码来获取文本文件中注册页面的输出

1 年，3 月 Questions & Answers 178

我对自动化非常陌生，我正在尝试使用cucumber框架自动化注册页面并在文本文件中获得输出。但我的Then部分似乎没有正确的代码，并且出现以下错误：组织。openqa。硒。NoTouchElementException:没有这样的元素：无法定位元素详情如下: 特色：客户注册场景概要：注册表的验证如果我能够访问客户登记表当我尝试填写“”和“” 我点击提交然后，我应该能够导航到注册成功的客户详细信息页面

# 1 楼答案
错误说明了一切：
```
org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"/html/body/table/tbody/tr[1]/td[2]"}
```
似乎WebDriver实例无法定位WebElement，您可能需要诱导一些WebDriverWait使元素可见，如下所示：

String S1 = new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//h2[normalize-space()='Registered Succesfully']//following::td[2]"))).getAttribute("innerHTML");

在这里您可以找到关于NoSuchElementException的详细讨论

更新A:

根据您的评论，您现在看到以下错误：

org.openqa.selenium.WebDriverException: chrome not reachable (Session info: chrome=63.0.3239.132) (Driver info: chromedriver=2.33.506120 (e3e53437346286c0bc2d2dc9aa4915ba81d9023f),platform=Windows NT 6.1.7601 SP1 x86_64) (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 4.01 seconds Build info: version: '2.47.1', revision: '411b314', time: '2015-07-30 02:56:46' *** Element info: {Using=xpath, value=//h2[normalize-space()='Registered Succesfully']//following::td[2]}

主要原因是您使用的二进制文件不兼容，因为：

您使用的是chromedriver=2.33

ChromeDriver=2.33的发行说明明确提到以下内容：

Supports Chrome v60-62

您的浏览器版本是63。x

因此，ChromeDriver和Chrome Browser之间存在明显的不匹配

解决方案

将您的ChromeDriver升级到最近的ChromeDriver=2.35级别
根据ChromeDriver=2.35的发行说明，将Chrome浏览器升级到Chrome v62-64级别
如果您的基本Chrome浏览器版本太旧，请通过Revo Uninstaller卸载Chrome浏览器，并安装最新发布的GA版本的Chrome浏览器

执行您的测试

更新B:

根据您的评论，您看到的错误如下：

org.openqa.selenium.WebDriverException: chrome not reachable (Session info: chrome=64.0.3282.167) (Driver info: chromedriver=2.35.528161 (5b82f2d2aae0ca24b877009200ced9065a772e73),platform=Windows NT 6.1.7601 SP1 x86_64) (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 4.01 seconds Capabilities [{applicationCacheEnabled=false, rotatable=false, mobileEmulationEnabled=false, networkConnectionEnabled=false, chrome={chromedriverVersion=2.35.528161

您使用的是硒版本（发布日期：2015-07-30 02:56:46）[根据您问题中的错误堆栈跟踪]

因此硒版本2.52.0和铬驱动=2.35之间的时间间隔几乎为3年，并且不兼容。因此，ChromeDriver无法生成新的Chrome浏览器进程

解决方案

将Selenium升级至当前级别版本3.9.1

您可以在Chromedriver frequently hangs when attempting to start a new session. Chrome not reachable中找到详细的讨论

# 2 楼答案

您缺少表单标记，其中包含表

您可以使用以下XPATH：-

String S1= driver.findElement(By.xpath("/html/body/form/table/tbody/tr[1]/td[2]/input")).getText();

或//td[text()='Customer Name']/following-sibling::td/input

# 3 楼答案

其他人都说了。我只想补充一点：当出现这样的错误时，检查元素的xpath是否正确非常有用。我发现这个答案很好地解释了这个问题：How to verify an XPath expression in Chrome Developers tool or Firefox's Firebug?

Firefox

Either select "Web Console" from the Web Developer submenu in the Firefox Menu (or Tools menu if you display the menu bar or are on Mac OS X)

or press the Ctrl+Shift+K (Command+Option+K on OS X) keyboard shortcut.

In the command line at the bottom use the following:

$(): Returns the first element that matches. Equivalent to document.querySelector() or calls the $ function in the page, if it exists.

$$(): Returns an array of DOM nodes that match. This is like for document.querySelectorAll(), but returns an array instead of a NodeList.

$x(): Evaluates an XPath expression and returns an array of matching nodes.

# 4 楼答案

看起来您使用的是绝对Xpath，而webdriver无法找到使用它的元素。您可以尝试使用以下Xpath：

By.xpath("//h2[text()='Registered Succesfully']//following::tr[1]/td[1]"));
