source code


Defines an object that runs Selenium commands.
    
    Element Locators
    ~~~~~~~~~~~~~~~~
    Element Locators tell Selenium which HTML element a command refers to.
    The format of a locator is:
    \ *locatorType*\ **=**\ \ *argument*
    We support the following strategies for locating elements:
    
    *    \ **identifier**\ =\ *id*
        Select the element with the specified @id attribute. If no match is
        found, select the first element whose @name attribute is \ *id*.
        (This is normally the default; see below.)
    *    \ **id**\ =\ *id*
        Select the element with the specified @id attribute.
    *    \ **name**\ =\ *name*
        Select the first element with the specified @name attribute.
    
        *    username
        *    name=username
        
        
    
        The name may optionally be followed by one or more \ *element-filters*, separated from the name by whitespace.  If the \ *filterType* is not specified, \ **value**\  is assumed.
    
        *    name=flavour value=chocolate
        
        
    *    \ **dom**\ =\ *javascriptExpression*
        
            Find an element using JavaScript traversal of the HTML Document Object
            Model. DOM locators \ *must* begin with "document.".
            *    dom=document.forms['myForm'].myDropdown
            *    dom=document.images[56]
            
            
        
    *    \ **xpath**\ =\ *xpathExpression*
        Locate an element using an XPath expression.
        *    xpath=//img[@alt='The image alt text']
        *    xpath=//table[@id='table1']//tr[4]/td[2]
        
        
    *    \ **link**\ =\ *textPattern*
        Select the link (anchor) element which contains text matching the
        specified \ *pattern*.
        *    link=The link text
        
        
    
    
    Without an explicit locator prefix, Selenium uses the following default
    strategies:
    
    *    \ **dom**\ , for locators starting with "document."
    *    \ **xpath**\ , for locators starting with "//"
    *    \ **identifier**\ , otherwise
    
    Element Filters
    ~~~~~~~~~~~~~~~Element filters can be used with a locator to refine a list of candidate elements.  They are currently used only in the 'name' element-locator.
    Filters look much like locators, ie.
    \ *filterType*\ **=**\ \ *argument*Supported element-filters are:
    \ **value=**\ \ *valuePattern*
    
    Matches elements based on their values.  This is particularly useful for refining a list of similarly-named toggle-buttons.\ **index=**\ \ *index*
    
    Selects a single element based on its position in the list (offset from zero).String-match Patterns
    ~~~~~~~~~~~~~~~~~~~~~
    Various Pattern syntaxes are available for matching string values:
    
    *    \ **glob:**\ \ *pattern*
        Match a string against a "glob" (aka "wildmat") pattern. "Glob" is a
        kind of limited regular-expression syntax typically used in command-line
        shells. In a glob pattern, "*" represents any sequence of characters, and "?"
        represents any single character. Glob patterns match against the entire
        string.
    *    \ **regexp:**\ \ *regexp*
        Match a string using a regular-expression. The full power of JavaScript
        regular-expressions is available.
    *    \ **exact:**\ \ *string*
        Match a string exactly, verbatim, without any of that fancy wildcard
        stuff.
    
    
    If no pattern prefix is specified, Selenium assumes that it's a "glob"
    pattern.

select(self, selectLocator, optionLocator)

source code 

Select an option from a drop-down using an option locator.

Option locators provide different ways of specifying options of an HTML Select element (e.g. for selecting a specific option, or for asserting that the selected option satisfies a specification). There are several forms of Select Option Locator.

  • label=labelPattern
matches options based on their labels, i.e. the visible text. (This is the default.) * label=regexp:^[Oo]ther
  • value=valuePattern
matches options based on their values. * value=other
  • id=id
matches options based on their ids. * id=option1
  • index=index
matches an option based on its index (offset from zero). * index=2

If no option locator prefix is provided, the default behaviour is to match on label.

'selectLocator' is an element locator identifying a drop-down menu 'optionLocator' is an option locator (a label by default)

add_selection(self, locator, optionLocator)

source code 

Add a selection to the set of selected options in a multi-select element using an option locator.

'formLocator' is an element locator for the form you want to submit

open(self, url)

source code 

Opens an URL in the test frame. This accepts both relative and absolute URLs.

The "open" command waits for the page to load before proceeding, ie. the "AndWait" suffix is implicit.

Note: The URL must be on the same domain as the runner HTML due to security restrictions in the browser (Same Origin Policy). If you need to open an URL on another domain, use the Selenium Server to start a new browser session on that domain.

'url' is the URL to open; may be relative or absolute

select_window(self, windowID)

source code 

Selects a popup window; once a popup window has been selected, all commands go to that window. To select the main window again, use "null" as the target.

'windowID' is the JavaScript window ID of the window to select

wait_for_pop_up(self, windowID, timeout)

source code 

Waits for a popup window to appear and load up.

'windowID' is the JavaScript window ID of the window that will appear 'timeout' is a timeout in milliseconds, after which the action will return with an error

choose_cancel_on_next_confirmation(self)

source code 
By default, Selenium's overridden window.confirm() function will return true, as if the user had manually clicked OK. After running this command, the next call to confirm() will return false, as if the user had clicked Cancel.

source code 

Has a prompt occurred?

This function never throws an exception

is_confirmation_present(self)

source code 

Has confirm() been called?

This function never throws an exception

get_alert(self)

source code 

Retrieves the message of a JavaScript alert generated during the previous action, or fail if there were no alerts.

Getting an alert has the same effect as manually clicking OK. If an alert is generated but you do not get/verify it, the next Selenium action will fail. NOTE: under Selenium, JavaScript alerts will NOT pop up a visible alert dialog. NOTE: Selenium does NOT support JavaScript alerts that are generated in a page's onload() event handler. In this case a visible dialog WILL be generated and Selenium will hang until someone manually clicks OK.

get_confirmation(self)

source code 

Retrieves the message of a JavaScript confirmation dialog generated during the previous action.

By default, the confirm function will return true, having the same effect as manually clicking OK. This can be changed by prior execution of the chooseCancelOnNextConfirmation command. If an confirmation is generated but you do not get/verify it, the next Selenium action will fail.

NOTE: under Selenium, JavaScript confirmations will NOT pop up a visible dialog.

NOTE: Selenium does NOT support JavaScript confirmations that are generated in a page's onload() event handler. In this case a visible dialog WILL be generated and Selenium will hang until you manually click OK.

get_prompt(self)

source code 

Retrieves the message of a JavaScript question prompt dialog generated during the previous action.

Successful handling of the prompt requires prior execution of the answerOnNextPrompt command. If a prompt is generated but you do not get/verify it, the next Selenium action will fail. NOTE: under Selenium, JavaScript prompts will NOT pop up a visible dialog. NOTE: Selenium does NOT support JavaScript prompts that are generated in a page's onload() event handler. In this case a visible dialog WILL be generated and Selenium will hang until someone manually clicks OK.

get_location(self)

source code 
Gets the absolute URL of the current page.

get_title(self)

source code 
Gets the title of the current page.

get_body_text(self)

source code 
Gets the entire text of the page.

get_value(self, locator)

source code 

Gets the (whitespace-trimmed) value of an input field (or anything else with a value parameter). For checkbox/radio elements, the value will be "on" or "off" depending on whether the element is checked or not.

'locator' is an element locator

get_text(self, locator)

source code 

Gets the text of an element. This works for any element that contains text. This command uses either the textContent (Mozilla-like browsers) or the innerText (IE-like browsers) of the element, which is the rendered text shown to the user.

'locator' is an element locator

get_eval(self, script)

source code 

Gets the result of evaluating the specified JavaScript snippet. The snippet may have multiple lines, but only the result of the last line will be returned.

Note that, by default, the snippet will run in the context of the "selenium" object itself, so this will refer to the Selenium object, and window will refer to the top-level runner test window, not the window of your application. If you need a reference to the window of your application, you can refer to this.browserbot.getCurrentWindow() and if you need to use a locator to refer to a single element in your application page, you can use this.page().findElement("foo") where "foo" is your locator.

'script' is the JavaScript snippet to run

is_checked(self, locator)

source code 

Gets whether a toggle-button (checkbox/radio) is checked. Fails if the specified element doesn't exist or isn't a toggle-button.

'locator' is an element locator pointing to a checkbox or radio button

get_table(self, tableCellAddress)

source code 

Gets the text from a cell of a table. The cellAddress syntax tableLocator.row.column, where row and column start at 0.

'tableCellAddress' is a cell address, e.g. "foo.1.4"

source code 

Verifies that the specified element is somewhere on the page.

'locator' is an element locator

is_visible(self, locator)

source code 

Determines if the specified element is visible. An element can be rendered invisible by setting the CSS "visibility" property to "hidden", or the "display" property to "none", either for the element itself or one if its ancestors. This method will fail if the element is not present.

'locator' is an element locator

is_editable(self, locator)

set_cursor_position(self, locator, position)

source code 

Moves the text cursor to the specified position in the given input element or textarea. This method will fail if the specified element isn't an input element or textarea.

'locator' is an element locator pointing to an input element or textarea 'position' is the numerical position of the cursor in the field; position should be 0 to move the position to the beginning of the field. You can also set the cursor to -1 to move it to the end of the field.

get_cursor_position(self, locator)

source code 

Retrieves the text cursor position in the given input element or textarea; beware, this may not work perfectly on all browsers.

Specifically, if the cursor/selection has been cleared by JavaScript, this command will tend to return the position of the last location of the cursor, even though the cursor is now gone from the page. This is filed as SEL-243.

This method will fail if the specified element isn't an input element or textarea, or there is no cursor in the element.

'locator' is an element locator pointing to an input element or textarea

set_context(self, context, logLevelThreshold)

source code 

Writes a message to the status bar and adds a note to the browser-side log.

If logLevelThreshold is specified, set the threshold for logging to that level (debug, info, warn, error). (Note that the browser-side logs will not be sent back to the server, and are invisible to the Client Driver.)

'context' is the message to be sent to the browser 'logLevelThreshold' is one of "debug", "info", "warn", "error", sets the threshold for browser-side logging

get_expression(self, expression)

source code 

Returns the specified expression.

This is useful because of JavaScript preprocessing. It is used to generate commands like assertExpression and waitForExpression.

'expression' is the value to return

wait_for_condition(self, script, timeout)

source code 

Runs the specified JavaScript snippet repeatedly until it evaluates to "true". The snippet may have multiple lines, but only the result of the last line will be considered.

Note that, by default, the snippet will be run in the runner's test window, not in the window of your application. To get the window of your application, you can use the JavaScript snippet selenium.browserbot.getCurrentWindow(), and then run your JavaScript in there

'script' is the JavaScript snippet to run 'timeout' is a timeout in milliseconds, after which this command will return with an error

set_timeout(self, timeout)

source code 

Specifies the amount of time that Selenium will wait for actions to complete.

Actions that require waiting include "open" and the "waitFor*" actions.

The default timeout is 30 seconds.

'timeout' is a timeout in milliseconds, after which the action will return with an error

wait_for_page_to_load(self, timeout)

source code 

Waits for a new page to load.

You can use this command instead of the "AndWait" suffixes, "clickAndWait", "selectAndWait", "typeAndWait" etc. (which are only available in the JS API). Selenium constantly keeps track of new pages loading, and sets a "newPageLoaded" flag when it first notices a page load. Running any other Selenium command after turns the flag to false. Hence, if you want to wait for a page to load, you must wait immediately after a Selenium command that caused a page-load.

'timeout' is a timeout in milliseconds, after which this command will return with an error
