WebDriver/PageObject/FindBy:如何指定具有动态值的xpath? [英] WebDriver/PageObject/FindBy: how to specify xpath with dynamic value?

问题描述

我正在尝试在Java中使用 Page Object 模式，并对 @ FindBy/XPath 遇到麻烦.

之前，我在Groovy中使用了以下构造:

driver.findElement(By.xpath("//td[contains(text(),'$SystemName')]")).click()

Here, SystemName is a parameter that can be different. 

现在，我想做同样的事情，但要遵循Java中的Page Object范式:

public class ManagedSystems {

    private WebDriver driver;

    @FindBy(id="menu_NewSystem")
    private WebElement menuNewSystem;

    @FindBy (xpath = "//td[contains(text(),'$SystemName')]")  // ??? How to use SystemName from deleteSystem method (below)?
    private WebElement plantSystemName;

    ....

    public SystemHomePage deleteSystem (String systemName) {

        plantSystemName.click();

    }

}

在我的测试中，我调用deleteSystem:

SystemHomePage.deleteSystem("Firestone");

问题:如何链接为PlantSystemName的 @FindBy表示法和为deleteSystem指定的 SystemName ?

解决方案

为此，我使用了另一种解决方法，即使在页面工厂的情况下，我们也可以使用动态xpath.

解决方案:添加任何静态父元素的xpath并引用具有动态路径的子元素. 在您的情况下，//td [contains(text()，'$ SystemName'))，td的父元素可能是'tr'或'table'.如果表是静态的，请使用以下代码:

@FindBy(xpath = "<..table xpath>")
public WebElement parentElement; 

public WebElement getDynamicEmement(String SystemName){
  parentElement.findElement(By.xpath("//tr/td[contains(text(),'"+SystemName+"')]"))
}

现在，在脚本中，首先访问表(以便将其引用加载到内存中)，然后调用getDynamicElement方法.

waitForElement(parentElement)
getDynamicElement("System-A")

I'm trying to use Page Object pattern in Java and having some trouble with @FindBy/XPath.

Earlier, I used the following construction in Groovy:

driver.findElement(By.xpath("//td[contains(text(),'$SystemName')]")).click()

Here, SystemName is a parameter that can be different. 

Now, I want to do the same thing but in accordance with Page Object paradigm in Java:

public class ManagedSystems {

    private WebDriver driver;

    @FindBy(id="menu_NewSystem")
    private WebElement menuNewSystem;

    @FindBy (xpath = "//td[contains(text(),'$SystemName')]")  // ??? How to use SystemName from deleteSystem method (below)?
    private WebElement plantSystemName;

    ....

    public SystemHomePage deleteSystem (String systemName) {

        plantSystemName.click();

    }

}

In my test, I call deleteSystem:

SystemHomePage.deleteSystem("Firestone");

Question: How to link @FindBy notation for PlantSystemName and SystemName specified for deleteSystem?

Thanks, Racoon

解决方案

I used another workaround for this which will allow us to use dynamic xpath even with page factory.

Solution: Add the xpath of any parent element that is static and reference child element with dynamic path. In your case, //td[contains(text(),'$SystemName'), parent element of td might be 'tr' or 'table'. If table is static, use below code:

@FindBy(xpath = "<..table xpath>")
public WebElement parentElement; 

public WebElement getDynamicEmement(String SystemName){
  parentElement.findElement(By.xpath("//tr/td[contains(text(),'"+SystemName+"')]"))
}

Now in your script, access table first(so that its reference is loaded in memory) and then call the getDynamicElement method.

waitForElement(parentElement)
getDynamicElement("System-A")
