C# Selenium Webdriver

I started using selenium with CS and have one issue. When code is compiled, program cannot find webdriver path, because it's being moved into the .exe file. I fixed this problem, by copying driver into the bin folder, so program can access it again. However, I want it to be able to access that driver inside .exe file.
I was doing this in python using os path:
def resource_path(relative_path: str) -> str:
try:
base_path = sys._MEIPASS
except Exception:
base_path = os.path.dirname(__file__)
return os.path.join(base_path, relative_path)
If anyone knows how to do this in cs, please let me know.
Code that I'm using in c#:
var browser = new EdgeDriver();
browser.Navigate().GoToUrl(link);

webdrivermanager should be more helpful here. you can add its Nuget and use to manage drivers for browsers without requiring the driver exe files.

I use something like this and call this method everytime I need a browser.
public static InternetExplorerDriver InitBrowser(string browserName)
{
switch (browserName)
{
case "IE":
{
var IE_DRIVER_PATH = #"C:\PathTo\IEDriverServer";
InternetExplorerDriver driver = new InternetExplorerDriver(IE_DRIVER_PATH);
return driver;
}
}
return null;
}
This allows you to define the path from which to grab the driver, and so you wont have to depend on it being in your BIN folder. There are other solutions but this is what I have that works really well for me. You are set up to use this method for other browsers by adding more switch cases, and also from here you can easily add your browser options. You can call the method in your tests using:
InternetExplorerDriver driver = InitBrowser(IE);
Here it is simplified without the switch case:
var IE_DRIVER_PATH = #"C:\PathTo\IEDriverServer";
InternetExplorerDriver driver = new InternetExplorerDriver(IE_DRIVER_PATH);

Having some trouble when opening chrome browser with Selenium ChromeDriver

I use Selenium ChromeDriver to open chrome browser and load a site into it programmatically.
I install selenium & ChromeDrive from this NuGet
Install-Package Selenium.WebDriver -Version 3.141.0 Install-Package
Selenium.WebDriver.ChromeDriver -Version 77.0.3865.4000
I have some questions:
if target pc has no chrome browser installed then how can i capture it by ChromeDriver ? is it possible?
when i am opening chrome browser by ChromeDriver instance then browser is opening chrome browser with a site but another CUI window is getting opened which i do not want to visible or i want to hide this CUI window. if it is not possible then how could i open this CUI window in minimize state?
a sample CUI window screen shot attached below when i work with FirefoxDriver. the same occur when i work with ChromeDriver instance.
when i executing this code chromeDriver.Close(); then opened chrome browser is getting closed but CUI window is still open. so if i click 5 times on open button then 5 CUI window is getting open along with 5 chrome browser instance which i had to close manually ....which i do not want to manually close it rather i want to close it when browser will be closed....how to achieve it ?
how to capture from code that opened chrome browser is close by this code chromeDriver.Close(); or if user click on cross button of chrome browser to close it?
how to open a new tab in already opened chrome browser instead of opening new chrome browser instance. if no chrome browser is open at all then new chrome browser will be open...how to achieve it by code. this below code opening new chrome browser always....what to change there for my point 5
chromeDriver = new FirefoxDriver(options);
chromeDriver.Navigate().GoToUrl("https://www.google.com");
another issue occur when i work with chrome driver that. it open chrome browser but a notification appear on browser like Chrome is being controlled by automated test software
I search google to hide it and found people said to use this option
options.setExperimentalOption("excludeSwitches", new String[] { "enable-automation" });
at my end this function does not available setExperimentalOption so what to do?
Please answer point wise with sample code.

For question 2,3 you can use below code
(use DriverService.Dispose(); to manually dispose driver service) :
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
namespace MyProject
{
public class Browser : IDisposable
{
bool disposed = false;
IWebDriver Driver;
public Browser()
{
//Chrome Driver copied on startup path
ChromeDriverService driverService = ChromeDriverService.CreateDefaultService(Application.StartupPath, "chromedriver.exe");
//hide driver service command prompt window
driverService.HideCommandPromptWindow = true;
ChromeOptions options = new ChromeOptions();
//hide browser if you need
//options.AddArgument("headless");
//or this to hiding browser
//options.AddArgument("--window-position=-32000,-32000");
//On offer Dona bhatt for disable automated test notification
options.AddExcludedArgument("enable-automation");
//options.AddArgument("disable-infobars");
Driver = new ChromeDriver(driverService, options);
}
public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
protected virtual void Dispose(bool disposing)
{
if (disposed)
return;
if (disposing)
{
Driver.Close();
Driver.Quit();
Driver.Dispose();
DriverService.Dispose();
}
disposed = true;
}
//this method for navigation
public string Navigate(string url)
{
string page = string.Empty;
try
{
Driver.Navigate().GoToUrl(url);
page =Driver.PageSource;
}
catch
{
}
return page;
}
//this method for wait to an element be visible by element ID
private void WaitUntilLoad(string id, int timeOut)
{
WebDriverWait waitForElement = new WebDriverWait(Driver, TimeSpan.FromSeconds(timeOut));
try
{
waitForElement.Until(ExpectedConditions.ElementIsVisible(By.Id(id)));
}
catch (WebDriverTimeoutException e)
{
}
}
}
}
Use this class:
using(Browser brw=new Browser())
{
string pageSource=brw.Navigate("My URL");
}

I couldn't post this as a comment because it's too long. I think this question is off topic but I just noted my comments on your items...
This seems to be much to broad. Are you having a problem with any specific issue? All of these seems like things you can research and find out.
1) The chrome driver has to be downloaded and shipped with your app.
2) It might be possible to hide that window but not sure why that would be a hard requirement. I'm going to just say that you can't by default prevent the window from showing.
3) You're going to have to close the chrome windows through your .net code. Selenium isn't going to be graceful enough to terminate all the chrome windows.
4) I'm not sure what you're asking for. What's the problem?
5) I think tabs might be done very differently between browsers, it might not be something natively supported in selenium. There might be some chrome driver commands that can facilitate but I have no idea what they are.
6) Again, this is typically not the preferred experience, I'm guessing one of your packages has a different featureset than whatever you're reading was using.

Headless Browser C# and Alternatives

currently I have the following code using selenium and phantomjs in c#:
public class Driver
{
static void Main()
{
using (var driver = new PhantomJSDriver())
{
driver.Navigate().GoToUrl("https://www.website.com/");
driver.Navigate().GoToUrl("https://www.website.com/productpage/");
driver.ExecuteScript("document.getElementById('pdp_selectedSize').value = '10.0'"); //FindElementById("pdp_selectedSize").SendKeys("10.0");
driver.ExecuteScript("document.getElementById('product_form').submit()");
driver.Navigate().GoToUrl("http://www.website/cart/");
Screenshot sh = driver.GetScreenshot();
sh.SaveAsFile(#"C:\temp\test.jpg", ImageFormat.Png);
}
}
}
My objective is to be able to add a product to my cart and then checkout automatically. The screenshot is just included to test whether the code was successfully working. My first issue is that I often get an error that it cannot find the element with product id "pdp_selectedSize". I'm assuming this is because the the webdriver hasn't loaded the page yet, so I'm looking for a way to keep checking until it finds it without having to set a specific timeout.
I'm also looking for faster alternatives to use instead of a headless browser. I used a headless browser instead of http requests because I need certain cookies to be able to checkout on the page, and these cookies are set through javascript within the page. If anyone has a reccommendation for a faster method, it would be greatly appreciated, thanks!

For your first question, it would behoove you to look into using ExpectedConditions' which is part of theWebDriverWaitclass inSelenium`. The following code sample was taken from here and only serves as a reference point.
using (IWebDriver driver = new FirefoxDriver())
{
driver.Url = "http://somedomain/url_that_delays_loading";
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
IWebElement myDynamicElement = wait.Until<IWebElement>(d =>
d.FindElement(By.Id("someDynamicElement")));
}
More on WebDriverWaits here.
As to your second question, that is a really subjective thing, in my opinion. Headless Browsers aren't necessarily any faster or slower than a real browser. See this article.

Unable to find an element in Browser of the Android emulator using Appium and C#

I want to automate mobile web site testing on Android emulator using c# and Appium. There is a simple test scenario I want to automate for the start:
1. Start Browser
2. Find an element
3. Clear it
4. Send keys
I've got a problem with the second step. Every time MSTest tries to execute FindElementById line in the code below, I get the error:
"An element could not be located on the page using the given search parameters."
[TestClass]
public class UnitTest1
{
private DesiredCapabilities _capabilities;
private AndroidDriver _driver;
public void InitializeDriver()
{
Console.WriteLine("Connecting to Appium server");
_capabilities = new DesiredCapabilities();
_capabilities.SetCapability("deviceName", "test_02");
_capabilities.SetCapability(CapabilityType.BrowserName, "Chrome");
_capabilities.SetCapability(CapabilityType.Version, "5.0.1");
_capabilities.SetCapability(CapabilityType.Platform, "Android");
//Application path and configurations
_driver = new AndroidDriver(new Uri("http://127.0.0.1:4723/wd/hub"), _capabilities);
}
[TestMethod]
public void TestMethod1()
{
InitializeDriver();
var element = _driver.FindElementById("com.android.browser:id/url");
element.Clear();
element.SendKeys(#"http://stackoverflow.com/");
}
}
Input string for the method I've got from UIAutomator that is shown below.
I tried several combinations for the FindElementById input method:
"com.android.browser:id/url"
"id/url"
"url"
but no luck.
My environment:
Windows 8.1
Appium 1.3.4.1
ChromeDriver 2.14.313457
Android Device Monitor 24.0.2

Sorry for misleading !!!
In case of testing web apps in browser the elements should be located as usual elements on the web page ( not as some classes like android.widget.EditText and android.widget.Button). So try for example the following and you will see some result:
var element = _driver
.findElementByXPath("//input[#id='lst-ib']");
To get locators you should run the browser on your desktop, open the page and use some tools/extensions like Firebug in Firefox or Firebug Lite in Chrome browser.

Try these 2 statements:
var element = _driver.FindElement(By.Id("com.android.browser:id/url");
driver.findElementsByXPath("//*[#class='com.android.browser' and #index='1']");

Update ! The following approach is not for web testing:
Could you try to find the element using xpath?
#FindBy(xpath="//android.widget.EditText[contains(#resource-id, 'url')]")
So in your case you can try the following:
var element = _driver.findElementByXPath("//android.widget.EditText[contains(#resource-id, 'url')]");
Update: in case of testing web apps (not native) you should use web page locators instead of Android classes.

Selenium-WebDriver opened the new Firefox window, but didn’t navigate to URL

My source code is copied from selenium docs site. I didn’t make any change.
http://docs.seleniumhq.org/docs/03_webdriver.jsp#user-input-filling-in-forms
I installed Selenium library via NuGet, including
Selenium Remote Control(RC), Selenium WebDriver Mono, Selenium WebDriver Support Classes, Selenium WebDriver, and Selenium WebDriver-backed Selenium.
When I run this code, a new Firefox window was opened. But the Firefox doesn’t navigate to the URL, it just stuck, nothing was loaded.
I tried the Firefox v27, v29, v30 and v31, none of them worked.
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
// Requires reference to WebDriver.Support.dll
using OpenQA.Selenium.Support.UI;
class GoogleSuggest
{
static void Main(string[] args)
{
// Create a new instance of the Firefox driver.
// Notice that the remainder of the code relies on the interface,
// not the implementation.
// Further note that other drivers (InternetExplorerDriver,
// ChromeDriver, etc.) will require further configuration
// before this example will work. See the wiki pages for the
// individual drivers at http://code.google.com/p/selenium/wiki
// for further information.
IWebDriver driver = new FirefoxDriver();
//Notice navigation is slightly different than the Java version
//This is because 'get' is a keyword in C#
driver.Navigate().GoToUrl("http://www.google.com/");
// Find the text input element by its name
IWebElement query = driver.FindElement(By.Name("q"));
// Enter something to search for
query.SendKeys("Cheese");
// Now submit the form. WebDriver will find the form for us from the element
query.Submit();
// Google's search is rendered dynamically with JavaScript.
// Wait for the page to load, timeout after 10 seconds
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
wait.Until((d) => { return d.Title.ToLower().StartsWith("cheese"); });
// Should see: "Cheese - Google Search"
System.Console.WriteLine("Page title is: " + driver.Title);
//Close the browser
driver.Quit();
}
}

I have had the same problem. the solution is simply uninstall your current firefox browser and download older version "i tried 2010 version 3.6.10 works great". your code is fine the problem is Mozilla people have decided to not give the right to any third party application to control Firefox.
good luck
