The functionality of SelectByText (partial) in C# Selenium WebDriver bindings appears to be malfunctioning

I am currently facing an issue using the Selenium WebDriver Extensions in C# to select a value from a select list by matching partial text. Despite trying different approaches, I can't seem to get it to work as expected. Could this be a mistake on my end or possibly a bug?

Below is a reproducible example:

using Microsoft.VisualStudio.TestTools.UnitTesting;
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.Support.UI;

namespace AutomatedTests
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void TestMethod1()
        {
            var driver = new FirefoxDriver();
            driver.Navigate().GoToUrl("http://code.google.com/p/selenium/downloads/list");
            var selectList = new SelectElement(driver.FindElement(By.Id("can")));
            selectList.SelectByText("Featured downloads");
            Assert.AreEqual(" Featured downloads", selectList.SelectedOption.Text);
            selectList.SelectByValue("4");
            Assert.AreEqual("Deprecated downloads", selectList.SelectedOption.Text);
            driver.Quit();
        }
    }
}

The error message received is:

OpenQA.Selenium.NoSuchElementException: Cannot locate element with text: Featured downloads

Answer №1

When I encountered issues with the SelectByText method, I took matters into my own hands and created a custom extension method called SelectBySubText to perform the necessary functionality.

using System.Linq;
using OpenQA.Selenium;
using OpenQA.Selenium.Support.UI;

namespace CustomExtensions
{
    public static class WebElementCustomExtensions
    {
        public static void SelectBySubText(this SelectElement element, string subtext)
        {
            foreach (var option in element.Options.Where(option => option.Text.Contains(subtext)))
            {
                option.Click();
                return;
            }
            element.SelectByText(subtext);
        }
    }

If you are able to recreate the issue on a basic HTML page, it is recommended that you report it as a bug.

Upon reviewing the source code, the method SelectByText first executes this:

FindElements(By.XPath(".//option[normalize-space(.) = " + EscapeQuotes(text) + "]"))

If no elements are found, it then tries:

string substringWithoutSpace = GetLongestSubstringWithoutSpace(text);
FindElements(By.XPath(".//option[contains(., " + EscapeQuotes(substringWithoutSpace) + ")]"))

In theory, this approach should work. You can also experiment with the XPath expression yourself to see if you can make it function in your particular scenario.
