This is the primary object for simulating user actions in Mozmill

Method overview

Attributes

controller.rootElement.keypress('t', {'ctrlKey':true});

Interaction Methods

check()

Fires a click at the given checkbox element to ensure it is either checked or not.

boolean check(
  in Elem element,
  in boolean state
); 

Parameters

element

An element to attempt to check (should be a checkbox or it will fail).

state

Pass true to ensure the element is checked, false to ensure it is unchecked. Defaults to false

Return value

true if the action succeeds, otherwise false.

Example

controller.check(new elementslib.ID(controller.window.document, 'foo'), true);

click()

Fires a normal (left) click at the given element. You can optionally pass in coordinates to the function for where to click. The coordinates are relative to the element's bounding rectangle. With no coordinates specified, it clicks as 0, 0 on that rectangle (top left corner).

boolean click(
  in Elem element,
  in int left,
  in int top
); 

Parameters

element

An element to click on

left

Left coordinate for click (optional, defaults to 0)

top

Top coordinate for click (optional, defaults to 0)

Return value

true if the action succeeds, otherwise false.

Example

controller.click(new elementslib.ID(controller.window.document, 'foo'));
// Or specify coordinates
controller.click(new elementslib.ID(controller.window.document, 'foo'), 20, 10);

doubleClick()

Fires a normal (left) double click at the given element. You can optionally pass in coordinates to the function for where to click. The coordinates are relative to the element's bounding rectangle. With no coordinates specified, it clicks as 0, 0 on that rectangle (top left corner).

boolean doubleClick(
  in Elem element,
  in int left,
  in int top
); 

Parameters

element

An element to click on

left

Left coordinate for click (optional, defaults to 0)

top

Top coordinate for click (optional, defaults to 0)

Return value

true if the action succeeds, otherwise false.

Example

                              new elementslib.ID(controller.window.document, 'bar'));

keypress()

Fires a keypress for the given keycode. The modifiers are a JSON object that specifies what key modifiers should be pressed in conjunction with the given key code. The available attribute names for the modifier object are: ctrlKey, altKey, shiftKey, metaKey, and accelKey. Try to avoid the usage of ctrlKey and metaKey if the shortcut is a combination of Ctrl (Windows/Linux) and Cmd (Mac) and use accelKey instead which will work regardless of which operating system your test is executing on.

boolean keypress(
  in Elem element,
  in string keycode,

select()

Handles selecting an option from a menu list or an HTML select element. The "element" corresponds to the list. There are multiple ways to select from such a list, either by "index", "label", or by the "value" associated with that option.

• index - to use an index, give it a valid index >=0. If you do not wish to use an index, pass 'null' for this field. Using an index of -1 will reset the current selection.
• label - to use label, supply the label. If you do not wish to use an option name, then pass 'null' in this field.
• value - to use the value attribute, supply the valid value in this field. If you choose not to supply a value, you can simply leave it off when not including it or pass in 'null'.

boolean select(
  in Elem element,
  in int index,
  in string label,
  in string value
); 

Parameters

element

An element to click on

index

index of item in drop down list. Use null if you do not wish to specify an index. -1 will reset the selection.

label

Label of the option you wish to select, if you do not wish to use it pass null

value

Value of the option you wish to select, if you do not wish to use this field either leave it off or pass null

Return value

true if the action succeeds, otherwise false.

Example

// Select only using the index
controller.select(new elementslib.ID(controller.window.document, 'foo'), 2);
// Select using the label of the given element
controller.select(new elementslib.ID(controller.window.document, 'foo'), null, 'bar');

startUserShutdown()

Creates a timeout window during which the browser is allowed to be restarted or shutdown, for example by selecting 'Quit' from the 'File' menu.  If startUserShutdown() is called and the test does not restart or shutdown the browser within the specified timeout, the test will fail.  The browser must also be shutdown within the same test that called startUserShutdown().  Note: This is only available in Mozmill 1.4.2 and later.

Parameters

timeout

The number of milliseconds during which the browser is allowed to be restarted or shutdown.

restart

True if a restart is to be expected, false if a shutdown is to be expected.

Return value

None

Example

controller.startUserShutdown(2000, false); 
controller.click(new elementslib.Elem(controller.menus["file-menu"].menu_FileQuitItem));

type()

Types a string of text at the given element.

boolean type(
  in Elem element,
  in string text
); 

Parameters

element

An element to type at

text

The text to type

Return value

true if the action succeeds, otherwise false.

Example

controller.type(new elementslib.ID(controller.window.document, 'foo'), 'some text to type');

Wait methods

sleep()

Causes the test to pause its execution until "timeout" milliseconds have passed. This is the least granular of the wait methods and is NOT encouraged to be used. It is only included here because it is sometimes useful when debugging. You should use other wait methods in your tests in order to ensure your tests are more deterministic.

void sleep(
  in int timeout
); 

Parameters

timeout

Number of milliseconds to pause.

Return value

None

Example

// Sleeps one second
controller.sleep(1000);

waitFor()

Waits until the callback handler returns true. The handler gets called every "interval" milliseconds, and if "timeout" milliseconds have passed without the handler return true, it gives up and causes the test to fail. If you use the defaults, then it will check the return value once every 100ms and will throw an error after 30 seconds have passed.

void waitFor(
  in func callback,
  in string message,
  in int timeout,
  in int interval,
  in object this
); 

Parameters

callback

A callback function or closure which executes code inside the scope of the test and has to return true/false.

message

Message to use for the raised exception when return value isn't true (optional)

timeout

Total time in milliseconds to wait (optional, default: 5000ms)

interval

How often to check if the element has appeared (optional, default: 100)

this

Reference to the outer scope's this object. It's needed when this has to be used inside the callback function.

None

Example

// Accept the default settings
var value = { message: "g" };
controller.waitFor(function () { 
  return value.message === 'foo'; 
}, "This is expected to fail.");
// Wait until the location bar is visible, check every 100ms, and if it isn't true by 1000ms then throw an error.
var locationBar = new elementslib.ID('urlbar');
controller.waitFor(function () { 
  return locationBar.getNode().visibility === true;
}, "Location bar should be visible", 1000, 100);

waitForElement()

Waits for the "element" to appear in the user interface (for instance if you wanted to wait for part of a page or dialog to load). It checks for "element" every "interval" milliseconds, and gives up if "timeout" milliseconds have passed without the "element" appearing, causing the test to fail. If you accept the defaults, it will check for the element every 100ms and will throw an error if 30 seconds pass without the element appearing.

void waitForElement(
  in Elem element,
  in int timeout,
  in int interval
); 

Parameters

element

Element to wait for

timeout

Total time in milliseconds to wait

interval

How often to check if the element has appeared

Return value

None

Example

// Typical usage - accept defaults.  See waitForEval() to see non-default operation
controller.waitForElement(new elementslib.ID(controller.window.document, 'foo'));

waitForEval()

Waits for the JavaScript "expression" to be true. It checks to see if the expression is true once every "interval" milliseconds, and if "timeout" milliseconds have passed without the expression becoming true, it gives up and causes the test to fail. If you use the defaults, then it will check the expression once every 100ms and will throw an error after 30 seconds have passed. The subject parameter which is passed as last argument will be substituted with the "subject" string inside the expression string. This method is deprecated, use the waitFor method instead.

void waitForEval(
  in string expression,
  in int timeout,
  in int interval,
  in object subject
); 

Parameters

expression

Expression to evaluate, optionally containing the word "subject" for substitution

timeout

Total time in milliseconds to wait

interval

How often to check if the element has appeared

subject

Object to substitute for the value of "subject" in the expression

Return value

None

Example

// Accept the default settings
controller.waitForEval('foo==true');
// Wait until the location bar is visible, check every 100ms, and if it isn't true by 1000ms then throw an error.
let locationBar = new elementslib.ID('urlbar')
controller.waitForEval('subject.visibility == true', 1000, 100, locationBar.getNode());

waitForImage()

Waits for the image represented by "element" to appear in the user interface. It checks for the image every "interval" milliseconds, and gives up if "timeout" milliseconds have passed without the "element" appearing, causing the test to fail. If you accept the defaults, it will check for the image every 100ms and will throw an error if 30 seconds pass without the image appearing.

void waitForElement(
  in Elem element,
  in int timeout,
  in int interval
); 

Parameters

element

Element to wait for

timeout

Total time in milliseconds to wait

interval

How often to check if the element has appeared

Return value

None

Example

// Typical usage - accept defaults.  See waitForEval() to see non-default operation
controller.waitForImage(new elementslib.ID(controller.window.document, 'foo'));

waitForPageLoad()

This is a browser specific method. It blocks the test until the current page completes loading.

void waitForPageLoad(
  in DOMDocument document,
  in int timeout,
  in int interval
); 

Parameters

document

Document to wait on, if not specified, uses the current document.

timeout

Total time in milliseconds to wait

interval

How often to check if the element has appeared

Return value

None

Example

// Waits for the current tab to load, timing out after 3 seconds have passed and
// it will check if the page is loaded every 100ms
controller.waitForPageLoad();
// Waits for the current page to load and will timeout once the given number of
// milliseconds have passed. For example, this times out after 1 second:
controller.waitForPageLoad(1000);
// The third version allows you to specify each parameter.  This allows you to specify
// what document is loading, the time that it must load within and how often to check that
// loading is complete.  For example, this waits for the page in tab 3 to load, and will
// check whether that page is loaded every 500ms, and will timeout after 2s have passed.
controller.waitForPageLoad(controller.tabs.getTab(3), 2000, 500);

waitThenClick()

Waits for the "element" to appear in the user interface. It checks for "element" every "interval" milliseconds, and gives up if "timeout" milliseconds have passed without the "element" appearing, causing the test to fail. Once "element" appears, a click event is immediately fired at it. This is a simple shortcut API for the common pattern of waiting for an element to appear before firing a click event on it.

void waitThenClick(
  in Elem element,
  in int timeout,
  in int interval
); 

Parameters

element

Element to wait for

timeout

Total time in milliseconds to wait

interval

How often to check if the element has appeared

Return value

None

Example

// Typical usage - accept defaults.  See waitForEval() to see non-default operation
controller.waitThenClick(new elementslib.ID(controller.window.document, 'foo'));

If the value parameter is specified, asserts that the given DOM attribute for the given element is not equal to the given value. If the assertion passes, it returns true, otherwise, it returns false and marks a failure in the test. This is very useful for asserting that various controls are not disabled, options are not selected etc. Note: This method is only available in Mozmill 1.4.2 and later.

boolean assertNotDOMProperty(
  in Elem element
  in string attribute
  [in string value]
); 

Parameters

element

Element to check

attribute

The DOM attribute to check

value

The value the DOM attribute is expected to not contain

controller.assertNotDOMProperty(new elementslib.ID(controller.window.document, 'fooControl'), 'name', 'bar');

assertNotJSProperty()

If the value parameter is not specified, asserts that the given Javascript object property does not exist for the given element. If the value parameter is specified, asserts that the given Javascript object property for the given element is not equal to the given value. If the assertion passes, it returns true, otherwise, it returns false and marks a failure in the test. This is very useful for asserting that various controls are not disabled, options are not selected etc. Note: This method is only available in Mozmill 1.4.2 and later.

boolean assertNotJSProperty(
  in Elem element
  in string attribute
  [in string value]
); 

Parameters

element

Element to check

attribute

The Javascript object property to check

value

The value the Javascript object property is expected to not contain

Return value

Boolean - returns true if assertion holds true, returns false if assertion is not true

Example

// True if there is no Javascript object property called 'disabled'
controller.assertNotJSProperty(new elementslib.ID(controller.window.document, 'fooControl'), 'disabled');
// True if the Javascript object property called 'name' doesn't have a value of 'bar'
controller.assertNotJSProperty(new elementslib.ID(controller.window.document, 'fooControl'), 'name', 'bar');

assertSelected()

Asserts that the given drop-down (or option) element has the given value selected. It uses the specified value of the selected option to verify this, you will have to usually look at the DOM Inspector to determine what this value should be.

boolean assertSelection(
  in Elem element,
  in string value
); 

Parameters

element

Element to check

value

The value of the option you expect to be selected

Return value

Boolean - returns true if assertion holds true, returns false if assertion is not true

Example

// Simple use for text boxes.
controller.assertText(new elementslib.ID(controller.window.document, 'foo'), '<b>bar</b>');
// If you had a XUL Description field of the form: <description id="mydesc">Some text here</description>
// Then you could use this statement to verify the "Some text here" string:
controller.assertText(new elementslib.ID(controller.window.document, 'mydesc'), '<i>Some text here</i>');

assertValue()

Asserts that the element contains the given value. This is typically used with input controls, like form elements, or textboxes. A primary use case is to shortcut when looking for the "value" attribute and ascertaining that it contains a certain value. You could of course just use the assertDOMProperty method.

boolean assertValue(
  in Elem element,
  in string value
); 

Parameters

element

Element to check

value

The value of the element that you expect

Return value

Boolean - returns true if assertion holds true, returns false if assertion is not true
