public class EventStream extends BaseClass
Note: this is currently an experimental feature and not covered by normal support guarantees. See Experimental Features for more information.

A EventStream captures event details as JavaScript objects as they are handled by the EventHandler. The event target canvas ID and class name as well the locator are included, as available. Event-specific data (for example, the String for keyboard events) are also included where appropriate. See EventStreamEvent for more information.

You can configure the stream to capture most DOM event types and other useful events, such as relogins and JavaScript errors that are triggered by events:

Event CategoryIncludes (source DOM eventType(s) or description) Controlling AttributeFrom DOM Event?
click eventsmouseDown, mouseUp, click, dblClickcaptureClickEventsY
move eventsmouseMove, mouseOut captureMoveEventsY
key eventskeyDown, keyPress, keyUpcaptureKeyEvents Y
drag eventsdragStart, dragMove, dragStopcaptureDragEvents Y
context menu eventscontextMenu captureMenuEventsY
mouse wheel eventsmouseWheel captureWheelEventsY
page eventsload, unload, resize capturePageEventsY
login eventsSuccessful relogin via the RPCManagercaptureLoginEvents N
Reify file events Project and screen (auto)saves and loadscaptureDSFileEventsN
event errorsJavaScript exceptions captureEventErrorsN
(Pointer and touch equivalents to mouse events have not been listed above. See the associated attribute for a more inclusive list.)

Note that several types of DOM events can be collapsed so that one event is reported instead of many if they occur over the same target. You can enable collapsing for move and drag events, key events, wheel events, and page events. A stream capture limit is also supported via circular buffering, so that only the most recent events are preserved. All available events can be returned as an array of EventStreamEvent via getEvents().

A EventStream will start capturing events as soon as it's created by default, but if you set autoStart: false, you can start capturing manually by calling start(). Calling end() will end capturing and return the EventStreamData.

    • setCaptureEventErrors

      public EventStream setCaptureEventErrors(boolean captureEventErrors) throws IllegalStateException
      Whether to capture JavaScript errors. If an already-captured event triggered the error, the details will attached to that event. Otherwise, a separate event will be created, with the eventType of the last dispatched DOM event (i.e., there is no special "error" eventType.)

      EventStreamEvent records annotated or specially-reported with error details will contain an errorTrace with the error stack trace, and a threadCode reporting the thread ID from the EventHandler responsible for the error.

      Parameters:
      captureEventErrors - New captureEventErrors value. Default value is true
      Returns:
      EventStream instance, for chaining setter calls
      Throws:
      IllegalStateException - this property cannot be changed after the underlying component has been created

    • getCaptureEventErrors

      public boolean getCaptureEventErrors()
      Whether to capture JavaScript errors. If an already-captured event triggered the error, the details will attached to that event. Otherwise, a separate event will be created, with the eventType of the last dispatched DOM event (i.e., there is no special "error" eventType.)

      EventStreamEvent records annotated or specially-reported with error details will contain an errorTrace with the error stack trace, and a threadCode reporting the thread ID from the EventHandler responsible for the error.

      Returns:
      Current captureEventErrors value. Default value is true

    • setCaptureKeyEvents

      public EventStream setCaptureKeyEvents(boolean captureKeyEvents) throws IllegalStateException
      Whether keyboard input events should be captured by the stream. For non-modifier keys, which includes all the self-inserting visible keyboard characters, we capture only the keyPress, as keyDown/keyUp are generally not useful. Conversely, for modifier keys (e.g. Shift), we capture only the keyDown and keyUp. events, and not the keyPress.

      If collapseKeyEvents is true, multiple adjacent keyPress events may be collapsed into a single event for greater readability and a more compact event trace.

      Note that if an error is thrown while handling an event, it will get reported regardless of this setting and the above capturing rules, but see minErrorReportingInterval. So for example an error handling a keyDown would still generally end up in the event trace, even for a self-inserting key such as "A".

      Parameters:
      captureKeyEvents - New captureKeyEvents value. Default value is false
      Returns:
      EventStream instance, for chaining setter calls
      Throws:
      IllegalStateException - this property cannot be changed after the underlying component has been created

      public EventStream setCaptureWheelEvents(boolean captureWheelEvents) throws IllegalStateException
      Whether mouse wheel events should be captured by the stream. If the preceding "wheel event" has the same targetID and scroll directions, it will be replaced by the current one, subject to collapseWheelEvents, with the delta offsets in the "collapsed" event getting adjusted to be the sum of those from all the original events.

    • setCollapseKeyEvents

      public EventStream setCollapseKeyEvents(boolean collapseKeyEvents) throws IllegalStateException
      Whether to collapse adjacent keyPress events into one event where possible. Self-inserting keys will generally be collapsed by concatenating them into a single string, EventStreamEvent.keyNames. On the other hand, special keys such as "Esc" and "Backspace" will only be collapsed for repeating sequences of the same key, which will be reported as EventStreamEvent.count.

    • setMaxSize

      public EventStream setMaxSize(Integer maxSize) throws IllegalStateException
      Maximum number of events that will be stored by this EventStream. After maxSize events are captured, the oldest events will be overwritten. Set this property to null to capture events without ever overwriting.
      Parameters:
      maxSize - New maxSize value. Default value is 10000
      Returns:
      EventStream instance, for chaining setter calls
      Throws:
      IllegalStateException - this property cannot be changed after the underlying component has been created

    • getMaxSize

      public Integer getMaxSize()
      Maximum number of events that will be stored by this EventStream. After maxSize events are captured, the oldest events will be overwritten. Set this property to null to capture events without ever overwriting.
      Returns:
      Current maxSize value. Default value is 10000

    • setMinErrorReportingInterval

      public EventStream setMinErrorReportingInterval(int minErrorReportingInterval) throws IllegalStateException
      Number of seconds that must elapse before another event error will be reported. This allows you to avoid the stream getting flooded with likely duplicate errors that may be rapidly and repeatedly reported, due to mouseMove or repeatedly executing code. Setting the property to zero disables it (avoiding any timestamp checking).

      Note that when an error is reported by the Framework, this property will be ignored if the last captured event triggered the error and has no errorTrace, so that it effectively only prevents adding new events to the stream specifically to report errors. However, an errorTrace attached to an event within the reporting interval of the previous error won't prevent that event from being collapsed.

      Parameters:
      minErrorReportingInterval - New minErrorReportingInterval value. Default value is 10
      Returns:
      EventStream instance, for chaining setter calls
      Throws:
      IllegalStateException - this property cannot be changed after the underlying component has been created
      See Also:

    • getMinErrorReportingInterval

      public int getMinErrorReportingInterval()

    • getAsSeleneseCommands

      public SeleniumCommand[] getAsSeleneseCommands()
      Creates and returns Selenese that represents the events captured by the stream as an array of Selenium commands. Compare with getAsSeleneseHTML(), where you'll also find more common details.

      Just as when retrieving the Selenese as HTML, if a transformSelenese() function has been defined, it's called before returning the Selenese.

      Returns:
      See Also:

    • getAsSeleneseCommands

      public SeleniumCommand[] getAsSeleneseCommands(SeleneseSettings settings)
      Creates and returns Selenese that represents the events captured by the stream as an array of Selenium commands. Compare with getAsSeleneseHTML(), where you'll also find more common details.

      Just as when retrieving the Selenese as HTML, if a transformSelenese() function has been defined, it's called before returning the Selenese.

      See Also:

    • getAsSeleneseHTML

      public String getAsSeleneseHTML()
      Creates and returns Selenese that represents the events captured by the stream. This Selenese contains Smart GWT-specific locators (scLocators), and Smart GWT command extensions (e.g. "waitForElementClickable") that are discussed in our Selenium overview.

      This method returns the Selenese as a string of HTML table rows, just as in an rctest.html file that you can directly execute with Selenium. Does not include the leading or trailing HTML, such as the <BODY> and <TBODY> tags; you'll need to wrap what's returned with the appropriate outer HTML tags to properly embed the table. If you'd rather have the Selenese returned as an array of Selenium commands, call getAsSeleneseCommands() instead.

      To customize the returned Selenese, see transformSelenese(). Note that if the stream has rolled over, the Selenese for the lost events will not be returned.

      For example, in your Entrypoint class definition, you can declare a stream member like: 

            EventStream eventStream = new EventStream();
      ... time passes where end user is interacting with your app .... Then to retrieve the Selenese you can call something like: 
            String rcTestHTML = "<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">" +
                          "<body><table><tbody>" +
                          MyApp.eventStream.getAsSeleneseHTML(true) +

    • getCypressScript

      public String getCypressScript(EventStream eventStream, String targetUrl, String testName, String testDescription)
      Builds a full Cypress test file by framing event commands in describe/it blocks. It adds a beforeEach with cy.visit, viewport setup, optional waits, and then the test steps.
      Parameters:
      eventStream - Stream of events to convert.
      targetUrl - URL to visit in beforeEach; defaults to current page.
      testName - Name of the it() block; defaults to "Test".
      testDescription - Description of the describe() block; defaults to "Testing".
      Returns:
      Complete Cypress spec code ready to paste into a `.spec.js`.

    • setEventErrorListener

      public void setEventErrorListener(EventErrorCallback callback)
      Installs a callback that will be called when the EventStream reports an event error, subject to the error reporting interval. The callback will be passed all retained EventStreamEvents captured by the stream since the last time it was called.
      Parameters:
      callback - Callback to fire when the stream encounters an event error, subject to the reporting interval
