/**
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 by evaluating the specified string.  This allows you to traverse the HTML Document Object
Model using JavaScript.  Note that you must not return a value in this string; simply make it the last expression in the block.
dom=document.forms['myForm'].myDropdown
dom=document.images[56]
dom=function foo() { return document.links[1]; }; foo();
xpath=xpathExpression: 
Locate an element using an XPath expression.
xpath=//img[@alt='The image alt text']
xpath=//table[@id='table1']//tr[4]/td[2]
xpath=//a[contains(@href,'#id1')]
xpath=//a[contains(@href,'#id1')]/@class
xpath=(//table[@class='stylee'])//th[text()='theHeaderText']/../td
xpath=//input[@name='name2' and @value='yes']
xpath=//*[text()="right"]
link=textPattern:
Select the link (anchor) element which contains text matching the
specified pattern.
link=The link text
css=cssSelectorSyntax:
Select the element using css selectors. Please refer to CSS2 selectors, CSS3 selectors for more information. You can also check the TestCssLocators test in the selenium test suite for an example of usage, which is included in the downloaded selenium core package.
css=a[href="#id3"]
css=span#firstChild + span
Currently the css selector locator supports all css1, css2 and css3 selectors except namespace in css3, some pseudo classes(:nth-of-type, :nth-last-of-type, :first-of-type, :last-of-type, :only-of-type, :visited, :hover, :active, :focus, :indeterminate) and pseudo elements(::first-line, ::first-letter, ::selection, ::before, ::after). 
ui=uiSpecifierString:
Locate an element by resolving the UI specifier string to another locator, and evaluating it. See the Selenium UI-Element Reference for more details.
ui=loginPages::loginButton()
ui=settingsPages::toggle(label=Hide Email)
ui=forumPages::postBody(index=2)//a[2]

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.
regexpi:regexpi:
Match a string using a case-insensitive regular-expression.
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.

For commands that return multiple values (such as verifySelectOptions),
the string being matched is a comma-separated list of the return values,
where both commas and backslashes in the values are backslash-escaped.
When providing a pattern, the optional matching syntax (i.e. glob,
regexp, etc.) is specified once, as usual, at the beginning of the
pattern.

/** Selects a popup window using a window locator; once a popup window has been selected, all

Window locators provide different ways of specifying the window object:
by title, by internal JavaScript "name," or by JavaScript variable.
title=My Special Window:
Finds the window using the text that appears in the title bar.  Be careful;
two windows can share the same title.  If that happens, this locator will
just pick one.
name=myWindow:
Finds the window using its internal JavaScript "name" property.  This is the second 
parameter "windowName" passed to the JavaScript method window.open(url, windowName, windowFeatures, replaceFlag)
(which Selenium intercepts).
var=variableName:
Some pop-up windows are unnamed (anonymous), but are associated with a JavaScript variable name in the current
application window, e.g. "window.foo = window.open(url);".  In those cases, you can open the window using
"var=foo".

If no window locator prefix is provided, we'll try to guess what you mean like this:
1.) if windowID is null, (or the string "null") then it is assumed the user is referring to the original window instantiated by the browser).
2.) if the value of the "windowID" parameter is a JavaScript variable name in the current application window, then it is assumed
that this variable contains the return value from a call to the JavaScript window.open() method.
3.) Otherwise, selenium looks in a hash it maintains that maps string names to window "names".
4.) If that fails, we'll try looping over all of the known windows to try to find the appropriate "title".
Since "title" is not necessarily unique, this may have unexpected behavior.
If you're having trouble figuring out the name of a window that you want to manipulate, look at the Selenium log messages
which identify the names of windows created via window.open (and therefore intercepted by Selenium).  You will see messages
like the following for each window as it is opened:
debug: window.open call intercepted; window ID (which you can use with selectWindow()) is "myNewWindow"
In some cases, Selenium will be unable to intercept a call to window.open (if the call occurs during or before the "onLoad" event, for example).
(This is bug SEL-339.)  In those cases, you can force Selenium to notice the open window's name by using the Selenium openWindow command, using
an empty (blank) url, like this: openWindow("", "myFunnyWindow").

"null", the first non-top window is selected. The top window is the one
that would be selected by selectWindow() without providing a
windowID . This should not be used when more than one popup
window is in play.
Otherwise, the window will be looked up considering
windowID as the following in order: 1) the "name" of the
window, as specified to window.open(); 2) a javascript
variable which is a reference to a window; and 3) the title of the
window. This is the same ordered lookup performed by
