I want to write my own locator to access the elements. WebDriver’s API offers currently eight locators allowing to retrieve elements by id, name attribute, tag name, complete or partial link text, XPath, class name, and css selector. However those default locators not enough for me now because I have to access the elements through a new attribute. Let me give an xample so that you can understand what I really want here.
Example: Choose your username:
Now I want to write a code so that I can access the username button using the myLocator locator like:
*driver.findElement(By.myLocator("username")).*
It would be very helpful if anybody can give us some good idea how could I rewrite the BY class to add my own locator.
Thank you in advance for your help.
using c#
using OpenQA.Selenium;
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
public class ImageBy : By
{
public ImageBy(string imageByString)
{
FindElementMethod = (ISearchContext context) =>
{
IWebElement mockElement = context.FindElement(By.XPath("//img[@src='" + imageByString + "']"));
return mockElement;
};
FindElementsMethod = (ISearchContext context) =>
{
ReadOnlyCollection<IWebElement> mockElements = context.FindElements(By.XPath("//img[@src='" + imageByString + "']"));
return mockElements;
};
}
}
and the usage would be as follows
[FindsBy(How = How.Custom, Using = @"/path/to/img", CustomFinderType = typeof(ImageBy) )]
private IWebElement MenuStartButton = null;
Using Java
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.SearchContext;
import org.openqa.selenium.WebElement;
public class ByImageSrc extends By
{
private final String imageByString;
public ByImageSrc(String imageByString)
{
this.imageByString = imageByString;
}
@Override
public List<WebElement> findElements(SearchContext context)
{
List<WebElement> mockElements = context.findElements(By.xpath("//img[@src='" + imageByString + "']"));
return mockElements;
}
}
usage :
WebElement element = driver.findElement(new ByImageSrc("/path/to/image"));
