      extends java.lang.Object

  Standalone class providing a general interface for integration with Automated Testing Tools

  For an overview of Automated Testing in Smart GWT, see the documentation `here`.

  ## AutoTestLocators

  The AutoTest class is responsible for creating and resolving `autoTestLocators` - identifier strings which can reliably identify an interactive element in a Smart GWT application.

  These locators are designed to work across browsers, Smart GWT versions, and even major changes to your application's UI. They do not rely on the DOM structure, and are intended to be able to identify the target element reliably without requiring pervasive explicitly specified `component IDs`.

  Note that AutoTest locators are the only supported way to identify Smart GWT generated DOM elements when recording tests for automated testing tools. Using XPath DOM locators to identify elements is not a supported approach. The DOM structure and DOM element attributes generated by Smart GWT components are not guaranteed to be identical for functionally equivalent elements across different Smart GWT builds, different browsers, and for dynamically generated components, could even change across page reloads.

  The primary APIs for working with AutoTest locators are as follows:

  - `getLocator()` to retrieve a locator for an element
  - `getElement()` to resolve a stored locator back to an element
  Developers should also be aware of the `installLocatorShortcut()` method which allows you to retreive locators via a simple key combo + mouseDown event on the target element.

  See the `AutoTestLocator overview` documentation for details on how locators are structured.

  See the `Reliable AutoTestLocators overview` documentation for best practices for generating high quality locators.

  ### AutoTest locator variables

  AutoTest locators may be written to include dynamic variables to be resolved at runtime. See the following APIs for details:
  - `setVariable()`: Set up a named variable for later use
  - `storeLocatorResult()`: Resolve a locator against the current environment and store it as a variable
  - `getVariable()`: Retrieves the value of a previously defined variable

  ### Locator testRoot

  For tests that target a standard widget hierarchy such as a `screen`, the `testRoot` may be used to reliably identify the widget hierarchy in question wherever it is rendered inside a larger application.

  ## Waiting for asynchronous operations

  The AutoTest class provides utilities to wait for asynchronous actions, including both system delays (such as `redraws that fire on system idle`, for example), and asynchronous `RPC operations`.
  - `waitForElement()`: this method will wait for asynchronous operations to complete before resolving an `AutoTestLocator` to an element and firing a callback function. This allows recorded tests to reference elements that are blocked or unavailable until some asynchronous action(s) complete.
  - `waitForSystemDone()`: this method will wait for any outstanding asynchronous system operations to complete and then fire the specified callback.
  - `isSystemDone()`: this method may be called to check whether there are currently any outstanding asynchronous system operations.
  Note that Smart GWT's support for integrating with high level tools such as `Cypress` and `Selenium` automatically makes use of these APIs.

      Convenience method to generate a `AutoTestLocator` with no search segments and an explicit path from the locator root to the target.

      This method sets `getLocator()` with the following configuration settings:

      - useSearchSegments:false
      - useMinimalFallbackAttributes:false
      - useCompactFallbackSyntax:false
      Parameters:
        `target` - Target within the page. This may be a DOM element, a `Canvas` or a `FormItem`. If null, a locator for the last mouse event target DOM element will be generated.
        `checkForNativeHandling` - If this parameter is passed in, check whether the target element responds to native browser events directly rather than going through the Smart GWT widget/event handling model. If we detect this case, return null rather than a live locator. This allows us to differentiate between (for example) an event on a Canvas handle, and an event occurring directly on a simple `<a href=...>` tag written inside a Canvas handle.
        `coords` - X, Y page position
      Returns:
        full-path locator string to identify the target. See `AutoTestLocator`

      Returns the `QualityIndicatedLocator` associated with some DOM element in a Smart GWT application page. If coords, representing the page position, is passed in, the locator may be generated with a specific trailing "target area" identifer that will map back to the appropriate, potentially different, physical coordinates, even if the widget is moved. The coords argument will only have an effect in cases where the mouse position over the target could potentially change behavior.
      Parameters:
        `DOMElement` - DOM element within in the page. If null the locator for the last mouse event target will be generated
      Returns:
        Locator details allowing the AutoTest subsystem to find an equivalent DOM element on subsequent page loads.

        minimal locator string to identify the target. See `AutoTestLocator`

    - #### installLocatorShortcut

          public static void installLocatorShortcut()

      This method allows developers to retrieve locators for elements on the page via a key-combo plus mouseDown on the element in question.
      It may be invoked from a bookmarklet stored in the browser, giving developers a one-click way to retrieve locators for any Smart GWT application

      When installLocatorShortcut() is invoked, it will register a Page-level `mouseDown` handler which, if the Shift+Ctrl or Shift+Meta key-combo are being held down will display the locator for the element under the mouse in a text-box and also copy it to clipboard.

      As with the `isc.showConsole()` method, developers may wish to create a bookmark in their browser to quickly enable this functionality on any Smart GWT application, without any changes to the application code:

      1. Create a new bookmark in your browser.
      2. Enter url "javascript:isc.AutoTest.installLocatorShortcut()".
      3. Label the bookmark as "Locator Shortcut"
      4. Consider adding this to the Bookmarks Toolbar. This allows you to enable the feature with a single click from any Smart GWT application.

      To uninstall the locator shortcut, call `uninstallLocatorShortcut()`

    - #### isSystemDone

          public static boolean isSystemDone()

      Returns a boolean to indicate whether the current application is fully loaded with no pending operations, and is ready for user interaction. This includes the following checks:
      - page has finished loading
      - all ListGrids (as defined by isc.isA.ListGrid) satisfy `isGridDone()`
      - all TileGrids that are drawn satisfy `isTileGridDone()`
      - all TileLayouts that are drawn satisfy `isTileLayoutDone()`
      - all DynamicForms that are drawn satisfy `isFormDone()`
      - all Canvii that are drawn satisfy `isCanvasDone()`
      In addition to this the `options` parameter allows developers to check additional criteria as documented under `SystemDoneConfig`.

      Note: `waitForSystemDone()` will poll this method repeatedly to check for all pending actions being complete. The `SystemWaitConfig` parameter of that method allow the user to speciofy which actions to wait for. By default `waitForSystemDone()` will wait for all actions to complete, including queued redraws, timers, network requests, as well as page load and comopnent level `isComponentDone` checks.

      Depending on your application configuration, it is possible that this method will not be able to determine whether it is truly in a busy state. Some examples include:

      - If `SystemDoneConfig.includeTimers` is true and the application has a constantly running background timer to perform some ongoing polling action or similar, this method may return `false` even though the application is ready for interaction
      - Similarly if `SystemDoneConfig.includeRedraws` is true, and the application is using messaging, or some other mechanism to periodically refresh component(s) such that they are repeatedly marked as dirty, this method may return `false` even though the application is ready for interaction
      - If this application makes use of some third-party library to perform asynchronous actions, this method may return `true` even when the application is waiting on a response from this third-party tool.
      Returns:
        whether loaded page is 'done' as described above

      - all ListGrids (as defined by isc.isA.ListGrid) satisfy `isGridDone()`
      - all TileGrids that are drawn satisfy `isTileGridDone()`
      - all TileLayouts that are drawn satisfy `isTileLayoutDone()`
      - all DynamicForms that are drawn satisfy `isFormDone()`
      - all Canvii that are drawn satisfy `isCanvasDone()`
      In addition to this the `options` parameter allows developers to check additional criteria as documented under `SystemDoneConfig`.

      Note: `waitForSystemDone()` will poll this method repeatedly to check for all pending actions being complete. The `SystemWaitConfig` parameter of that method allow the user to speciofy which actions to wait for. By default `waitForSystemDone()` will wait for all actions to complete, including queued redraws, timers, network requests, as well as page load and comopnent level `isComponentDone` checks.

      Depending on your application configuration, it is possible that this method will not be able to determine whether it is truly in a busy state. Some examples include:

      - If `SystemDoneConfig.includeTimers` is true and the application has a constantly running background timer to perform some ongoing polling action or similar, this method may return `false` even though the application is ready for interaction
      - Similarly if `SystemDoneConfig.includeRedraws` is true, and the application is using messaging, or some other mechanism to periodically refresh component(s) such that they are repeatedly marked as dirty, this method may return `false` even though the application is ready for interaction
      - If this application makes use of some third-party library to perform asynchronous actions, this method may return `true` even when the application is waiting on a response from this third-party tool.
      Parameters:
        `options` - This parameter determines what specific outstanding actions are required to be completed before the system is considered "done" with current processing. If passed as a boolean rather than a SystemDoneConfig object, this determines whether the system should wait for `pending redraws`.
      Returns:
        whether loaded page is 'done' as described above

    - #### isSystemDone

          public static boolean isSystemDone(boolean options)

      Returns a boolean to indicate whether the current application is fully loaded with no pending operations, and is ready for user interaction. This includes the following checks:
      - page has finished loading
      - all ListGrids (as defined by isc.isA.ListGrid) satisfy `isGridDone()`
      - all TileGrids that are drawn satisfy `isTileGridDone()`
      - all TileLayouts that are drawn satisfy `isTileLayoutDone()`
      - all DynamicForms that are drawn satisfy `isFormDone()`
      - all Canvii that are drawn satisfy `isCanvasDone()`

    - #### setTestRoot

          public static void setTestRoot(Canvas canvas)

      Sets the implicit root canvas available in scLocators starting "//testRoot[]". Setting this property may enable one to use the same script to test identical widget hierarchies that are rooted under different base widgets.
      Parameters:
        `canvas` - the implicit root

      Waits for any in-progress actions to complete and then returns the element for the specified locator.

      By default this method will wait for the `system to be done` before calling `getElement()` with the specified locator. The `waitStyle` attribute of the options parameter may be used to instead wait for the locator to resolve to a `clickable element`.

      Parameters:
        `locator` - locator for the element to retrieve. See `AutoTestLocator`
        `callback` - callback to fire when the element has been retrieved - takes two parameters:
        - "element" (DOMElement) - the clickable element the locator resolved to (or null)
        - "done" (boolean) - this will be false if the method timed out
        . See `Callback`

    - #### waitForElement

          public static void waitForElement(java.lang.String locator,
                                            java.lang.String callback,
                                            ElementWaitConfig options)

      Waits for any in-progress actions to complete and then returns the element for the specified locator.

      By default this method will wait for the `system to be done` before calling `getElement()` with the specified locator. The `waitStyle` attribute of the options parameter may be used to instead wait for the locator to resolve to a `clickable element`.

      Parameters:
        `locator` - locator for the element to retrieve. See `AutoTestLocator`
        `callback` - callback to fire when the element has been retrieved - takes two parameters:
        - "element" (DOMElement) - the clickable element the locator resolved to (or null)
        - "done" (boolean) - this will be false if the method timed out
        . See `Callback`
        `options` - Options to configure the wait

    - #### waitForSystemDone

          public static void waitForSystemDone(java.lang.String callback)

      By default this will wait for the following system actions to complete:

      - All outstanding Smart GWT `RPC and DataSource requests`
      - All outstanding FileLoader requests
      - Any `queued redraws`
      - Any non-recurring delayed actions
      Note that this behavior may differ from the default settings for `isSystemDone()`

      The `options` parameter gives developers finer grained control over what to wait for.

      Parameters:
        `callback` - Action to fire. This will take a single parameter "done" which will be set to false if the method timed out waiting for isSystemDone() to return true;. See `Callback`
