Open(String, TargetAppOptions, String, String)​

Abre una aplicación de escritorio o página web específica para utilizar en la automatización de la interfaz de usuario, identificada por el nombre de pantalla del repositorio de objetos.

Open(
    string screenName,  
    TargetAppOptions targetAppOptions, 
    [string appName],
    [string appVersion])
Open(
    string screenName,  
    TargetAppOptions targetAppOptions, 
    [string appName],
    [string appVersion])

screeName Cadena : el nombre de la pantalla en la que quieres centrarte, como una Cadena grabada dentro del Repositorio de objetos.

targetAppOptions : opciones y ajustes adicionales para adjuntar a la aplicación o página web:

* `Timeout Double` - Specify a number
  of seconds for which to wait for the activity to be executed before
  throwing an error. The default value is 30 seconds. When indicating
  a window in a Remote Desktop environment, the Timeout default
  setting is set to 60 seconds.
* `InteractionMode
  NInteractionMode`:
  + `HardwareEvents` - Uses the hardware
    driver to perform the action. This is the slowest API, it
    cannot work in the background, but it is compatible with all
    desktop apps.
  + `Simulate` - Simulates the action using
    accessibility APIs. Recommended in browser automation, Java
    apps, or SAP. More reliable than Hardware Events. Sends all
    text in a single action. Works even if the target
    application is not in focus. Please test if your target
    application UI element supports this.
  + `DebuggerApi` - Performs actions using
    debugger APIs. Works only for Chromium elements. Sends all
    text in one go. Works even if target app is not in focus.
    For more details, check out this [page](https://docs.uipath.com/studio/docs/chromium-api).
  + `WindowMessages` - Sends the mouse and
    keyboard input through Win32 messages. Recommended for
    desktop apps. Usually more reliable than Hardware Events.
    Sends all text in a single action. Works even if target app
    is not in focus. Please test if your target application UI
    element supports this.
  + `Background` - Runs actions in the
    background. Tries to use either Simulate or Chromium API
    where possible, while complex APIs (image, native text)
    run as usual, in the foreground. It is highly recommended to
    use this API with the [Verify Execution](https://docs.uipath.com/activities/other/latest/user-guide/project-settings-ui-automation)
    feature.
* `OpenMode NAppOpenMode` - choose when
  to open the app:
  + `Never` (never open the
    application)
  + `IfNotOpen` (open only if the
    application is closed, this is the default selection, only
    works if `FilePath` or `URL`
    are provided)
  + `Always` (open another instance of the
    application even if one is already open, only works if
    `FilePath` or `URL` are
    provided)
* `WindowResize NWindowResize` - choose
  the size of the window:
  + `None`
  + `Maximize`
  + `Restore`
  + `Minimize`
* `UserDataFolderMode
  BrowserUserDataFolderMode` - The
  `UserDataFolderMode` you want to set. It is used
  to start the browser with a specific user data folder.
  + `Automatic` - Picture In Picture mode
    uses a different folder than the default mode, automatically
    generated if `UserDataFolderPath` is not
    set.
  + `DefaultFolder` - Uses the default
    browser folder, no matter if it runs in the main or PIP
    session.
  + `CustomFolder` - Uses the folder
    specified in `UserDataFolderPath` or an auto
    generated path if `UserDataFolderPath` is not
    set.
* `UserDataFolderPath String` - The
  user data folder that the browser uses. Defaults to
  `%LocalAppData%\UiPath\PIP Browser
  Profiles\BrowserType` if not set.
* `IsIncognito Boolean` - input
  `True` if you want to open the browser in
  incognito mode. By default it's set to `False`.
* `WebDriverMode NWebDriverMode` -
  Indicates how the WebDriver is used when opening a new browser
  session. The following options are available:
  + `Disabled` - Disables the use of
    WebDriver.
  + `WithGUI` - The GUI of the browser is
    displayed.
  + `Headless` - The browser is launched
    silently, with no GUI.
* `Timeout Double` - Specify a number
  of seconds for which to wait for the activity to be executed before
  throwing an error. The default value is 30 seconds. When indicating
  a window in a Remote Desktop environment, the Timeout default
  setting is set to 60 seconds.
* `InteractionMode
  NInteractionMode`:

    text in a single action. Works even if the target
    application is not in focus. Please test if your target
    application UI element supports this.

Ejecutar WebDriverMode como Headless​

Para operar WebDriverMode en una configuración sin interfaz gráfica, estos pasos pueden servir como guía.

Comienza definiendo una variable para tu pantalla. Utiliza la función uiAutomation.Open para abrir una nueva aplicación en el navegador de tu elección: en esta instancia, Edge.Después de eso, utiliza la clase Options en la sobrecarga para especificar ciertas opciones del navegador.Entre estas opciones, establece webDriverMode en NWebDriverMode.Headless.

El código correspondiente se ve así:

var screen = uiAutomation.Open(Descriptors.NewApplication.Edge, Options.AppOpen().WithBrowserOptions(webDriverMode: NWebDriverMode.Headless));
var screen = uiAutomation.Open(Descriptors.NewApplication.Edge, Options.AppOpen().WithBrowserOptions(webDriverMode: NWebDriverMode.Headless));

Este código funciona para establecer tu WebDriver en modo sin interfaz gráfica, habilitando la automatización del navegador sin que el navegador esté visiblemente abierto.
