FBTest Object

A test, specifically the test driver part, usually use APIs that are provided by the FBTest framework. The test driver uses them to communicate back to the framework and automate Browser and Firebug UI. All APIs are accessible via FBTest object that is automatically defined as a global variable within a test driver scope. Let's see what methods are available:

  • ok(pass, msg) - generates a test report into the test console. If the first parameter is true the report is considered as passing, otherwise failing. If all reports from a test case pass, the entire test case is considered as passing, otherwise failing.
  • compare(expected, actual, msg) - also generates a test report. If the expected string equals to actual, the report is considered as passing.
  • sysout(text, obj) - prints an informative log into Firebug's tracing console. You need to have TESTCASE option selected.
  • testDone() - this method must be called at the end of each test. This informs the framework that a test has been finished.
  • progress(msg) - prints an informative message into the Test console status bar.
  • loadScript(scriptURI, scope) - loads additional script file.
  • getLocalURLBase() - returns local path of the home server directory (e.g. C:\firebug\tests\content\)
  • exception(message, err) - generates an exception report into the test console. This report is always marked as failing.
  • resetTimeout() - resets the timeout, so test cases, which take longer to execute, won't run into a timeout


Example of exception logging

function runTest()
{
    FBTest.sysout("exampleTest.started");
    try
    {
        hello.world(); // EXCEPTION
    }
    catch (err)
    {
        FBTest.exception("Test: ", err);
    }
    finally
    {
        FBTest.testDone();
    }
}


Firebug UI

  • openFirebug() - opens Firebug UI as a bar at the bottom of the Firefox Window (reffered as the Firebug Window).
  • closeFirebug() - closes Firebug UI.
  • pressToggleFirebug(forceOpen) - toggles (open/close) Firebug UI.
  • detachFirebug() - detaches Firebug from the Firebug Window.
  • isFirebugOpen() - returns true if Firebug is currently opened.
  • closeFirebugOnAllTabs() - closes Firebug UI on all tabs.


Firebug Activation

Helpers for panel acivation (enablement)

  • enableNetPanel(callback)
  • disableNetPanel(callback)
  • enableScriptPanel(callback)
  • disableScriptPanel(callback)
  • enableConsolePanel(callback)
  • disableConsolePanel(callback)
  • disableAllPanels()
  • enableAllPanels()


Panels

  • selectPanel(panelName) - selects specific panel within Firebug UI.
  • getSelectedPanel() - returns an object that represents currently selected panel.
  • getPanel(panelName) - returns an object that represents specified panel ("console", "script, "net", etc.).
  • selectPanelLocationByName(panel, name)
  • selectSourceLine(url, lineNumber, category)


Preferences

Helpers for Firebug Preferences. Notice that prefName must be specified without Firebug's preference domain. See example below.

  • setPref(prefName, value)
  • getPref(prefName)


var value = FBTest.getPref("showXMLHttpRequests");
FBTest.setPref("showXMLHttpRequests", true);

In this case extensions.firebug.showXMLHttpRequests preference is used.


Firefox

  • openNewTab(url, callback) - opens a new Firefox tab with the specified URL. As soon as the page is loaded provied callback is executed.
  • openURL(url, callback) - opens a specified URL on the current Firefox page.
  • reload(callback) - reloads the current Firefox page.
  • cleanUpTestTabs() - closes all Firefox tabs, that have been opened as part of the testing process.


DOM

  • expandElements(parentNode, className [, className, ...]) - sends a click event to all child elements, that use the specified class(s). This is useful mainly for expanding various panel contents.
var panel = FW.FirebugChrome.selectPanel("net").panelNode;
FBTest.expandElements(panelNode, "netRow", "category-xhr");

Expands all XHR requests within the Net Panel (sends click event to all elements that have both netRow and category-xhr classes).


Events

  • click(node) - fires a click event on specified DOM node
  • dblclick(node) - fires a double-click event on specified DOM node
  • rightClick(node) - fires a right-click event on specified DOM node
  • mouseDown(node) - fires a mousedown event on specified DOM node
  • pressKey(keyCode, target) - fires a key event on specified DOM node
  • sendChar(aChar, aTarget) - sends a char to specified DOM node in respect of char casing (sends shift key for uppercase chars; currently just works for English letters)
  • sendString(aStr, aTarget) - sends a string to specified DOM node (currently just works for English letters and digits)
  • sendKey(aKey, aTarget) - sends a non-char key to specified DOM node (name should be lowercase part of what comes after DOM_VK_ constants)
  • synthesizeKey(aKey, aWindow) - synthesizes a key press event to whatever would be targeted by that event (typically the focused element)
  • focus(node) - focuses specified DOM node either using a focus method or firing a DOMFocusIn event on the node


Debugger


Miscellaneous

  • testDone(msg) - finishes a Firebug related test. This methods also closes Firebug UI, all test tabs and uses specified message as a progress mesasage in the Test console status bar.
  • clearCache() - clear Firefox cache.
