Appium Android Windows：driver.findElement(By.name(" ")) 不能连续工作

Question

WebElement username=driver.findElement(By.name("username"));
username.sendKeys("test");
WebElement password=driver.findElement(By.name("password"));         
password.sendKeys("test");
WebElement loginBtn=driver.findElement(By.name("Login"));
loginBtn.click();       
WebElement backBtn=driver.findElement(By.tagName("Button"));
backBtn.click();

当我使用上述测试用例时，用户名运行成功，但在输入密码时显示以下错误。

为什么 findElement(By.name("")) 第二次不工作了？

Answer 1

使用 Appium Inspector 检查 -> 字段“密码”可能没有任何名称值设置为“密码”来访问它。

尝试使用 xpath 访问元素，例如：

  WebElement password = driver.findElement(By.xpath("//window[1]/scrollview[1]/secure[1]"));
  password.click();
  password.sendKeys("psswrd");

按照以下步骤使用 Appium Inspector 获取 xpath 或其他属性：

[1] Launch Appium server.
[2] Check the check box 'App Path'.
[3] Click on the 'Choose' button and select your .app file location from your local, e.g. xyz.app
[4] Now click on the 'Launch' button . Once appium server is launched, the blue color icon besides the 'Launch' button is enabled.
[5] Click on the blue color icon, it will open up the appium inspector and simulator with your application :

您将看到应用的元素层次结构显示名称、xPath、值等属性。
