크롬 디버깅 모드 실행

chrome.exe --remote-debugging-port=9222 --user-data-dir="C:/Users/root/Desktop/ChromeDebug"

이렇게 실행하지 않으면 절때 셀레니움 창으로 디버깅할수없다.

C#

• 패키지로 설치하면 ChromeDriver.exe 가 자동적으로 생성된다.

• Visual Studio에서 도구 > NuGet 패키지 관리자 > 패키지 관리자 콘솔(알트 T N O)

        Install-Package Selenium.WebDriver.ChromeDriver   
        Install-Package Selenium.WebDriver
        Install-Package Selenium.Support
  

• 기본적인코드

        ChromeDriverService _driverService = null;
        ChromeOptions _options = null;
        ChromeDriver _driver = null;
  
        //_options.AddArgument("headless");
        //_options.AddArgument("no-sandbox");
        //_options.AddArgument("disable-gpu");
        //_options.AddArgument("window-size=1920x1080");
        //_options.AddArgument("disable-gpu");
  
        _driverService = ChromeDriverService.CreateDefaultService();
        _driver = new ChromeDriver(_driverService);
  

• 디버깅모드 컨트롤

    ChromeDriverService _driverService = null;
    ChromeOptions _options = null;
    ChromeDriver _driver = null;
    _options = new ChromeOptions();
    _options.DebuggerAddress = "127.0.0.1:9222";
    _driver = new ChromeDriver(_options);
  

• 타입아웃설정 / 이동

    _driver.Manage().Timeouts().PageLoad = TimeSpan.FromSeconds(10);
    _driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);
    _driver.Navigate().GoToUrl("https://test.com");
  

• 자바스크립트 실행

    String Javascript = String.Format(
        "document.getElementById('id').value = '{0}';document.getElementById('pw').value = '{1}';", 
        username, userpassword);
    ExecuteScript(_driver, Javascript);
  

• 키입력

    element.SendKeys(OpenQA.Selenium.Keys.Enter);
  

• 객체찾기 IWebElement 에서는 By.XPath 로 추가적으로 찾을수있다.

    IWebElement close = _driver.FindElementByXPath(
        "//div[@class='modal-dialog']//button[@aria-label='닫기']"
    );
  

• 문자열로 element 를 찾는다면

    //*[contains(text(), '확인')]
  

• 프레임접근

    IWebElement iframe = _driver.FindElementByXPath("//iframe");
    _driver.SwitchTo().Frame(iframe);
  

• 탭접근

     _driver.SwitchTo().Window(_driver.WindowHandles.First());
     _driver.SwitchTo().Window(_driver.WindowHandles.Last());
  

• 닫기

    _driver.Close(); // 현재창만 닫음
    _driver.Quit();  // 크롬전체를 닫음
