DelphiWebDriver

A modern, lightweight Delphi client (No third party) for the W3C WebDriver protocol (the same protocol used by Selenium). This library allows Delphi developers to automate browsers such as Chrome, Firefox, and Edge by communicating with their corresponding WebDriver executables.

✨ Features

• Create and manage WebDriver sessions
• Navigate to URLs
• Locate elements (By.Id, By.Name, By.ClassName, By.CSS, By.XPath...)
• Click elements, send keys, submit forms
• Take screenshots and save to file
• Wait for elements to appear or conditions to be true
• Manage cookies, frames
• Interface-based memory management for stability
• Cross-browser support (Chrome, Firefox, Edge)
• headless mode support (Chrome, Firefox, Edge)
• And more cool stuff is coming...

🚀 Getting Started

Requirements

• Delphi 10.2+ (or any recent version)

• Corresponding WebDriver binaries:

  • ChromeDriver - Chrome (download from here https://developer.chrome.com/docs/chromedriver/downloads)
  • GeckoDriver - Firefox (download from here https://github.com/mozilla/geckodriver/releases)
  • MSEdgeDriver - Edge (download from here https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver)

Place the driver executable next to your application.

Example Usage

uses
  DelphiWebDriver.Core,
  DelphiWebDriver.Types,
  DelphiWebDriver.Server,
  DelphiWebDriver.Interfaces;

procedure TMainForm.StartDriverButtonClick(Sender: TObject);
var
  Server: TWebDriverServer;
  Driver: IWebDriver;
begin
  var DriverName := '';
  var BrowserName := '';
  if ChromeRadioButton.IsChecked then
    begin
      DriverName  := TWebDriverBrowser.Chrome.DriverName;
      BrowserName := TWebDriverBrowser.Chrome.Name;
    end;
  if FirefoxRadioButton.IsChecked then
    begin
      DriverName  := TWebDriverBrowser.Firefox.DriverName;
      BrowserName := TWebDriverBrowser.Firefox.Name;
    end;
  if EdgeRadioButton.IsChecked then
    begin
      DriverName  := TWebDriverBrowser.Edge.DriverName;
      BrowserName := TWebDriverBrowser.Edge.Name;
    end;

  if DriverName.IsEmpty then
    begin
      LogsMemo.Text := 'You must select driver';
      Exit;
    end;

  // if you have specific path for the driver path then set it with the DriverName
  // for ex : Server := TWebDriverServer.Create('C:\drivers_folder\' + DriverName);

  Server := TWebDriverServer.Create(DriverName);
  try
    Server.Start;
    Driver := TWebDriver.Create('http://localhost:9515');
    try
      Driver.Capabilities.BrowserName := BrowserName;
      Driver.Capabilities.Headless := HeadlessModeCheckBox.IsChecked;
      // Optional
      // Driver.Capabilities.Args.Add('--disable-gpu');
      // Driver.Capabilities.Args.Add('--window-size=1920,1080');
      Driver.Sessions.StartSession;
      Driver.Navigation.Navigate('https://www.google.com');
      Driver.Wait.WaitUntilPageLoad;
      LogsMemo.Text := Driver.Document.GetPageSource;
      Driver.Screenshot.SaveScreenshotToFile('Screenshot.png');
    finally
      Driver.Sessions.Quit;
    end;
  finally
    Server.Stop;
    Server.Free;
  end;

end;

⚡ Notes

• Use interface variables (IWebDriver, IWebElement) for safe automatic memory management.
• Avoid keeping element references after quitting the driver.
• WaitUntilElement supports Id, Name, ClassName, CSS Selector, XPath.
• TWebDriverServer helps start/stop ChromeDriver for your tests.
