Finding Elements
Identifing elements: identifier=id: @id/@name
id=id: Select the element with the specified @id attribute.
name=name: Select the first element with the specified @name
attribute.
dom=function foo() { return document.links[1]; }; foo();
link=textPattern

Finding Elements
String-match Patternsglob:pattern: "*": any sequence of
characters
"?": any single character.
Glob patterns match against the entire string.
regexp:regexp: match a string using a regular-expression.
exact:string: match a string exactly
Finding Elements (2)
Resolving strategies:dom, for locators starting with
"document."
xpath, for locators starting with "//"
identifier, otherwise
Css Selectors
all css1, css2 and css3 selectors (except namespaces in
css3)css=a[href="#id3"]
css=span#firstChild + span
pseudo classes :nth-of-type, :nth-last-of-type, :first-of-type,
:last-of-type
:visited, :hover, :active, :focus
pseudo elements::first-line,::first-letter, ::selection,
::before, ::after
examples: div#id, div.class, div > p > a
a[href=http://www.google.com]
Xpath Selectors
Level Separator: /Every Level: //Wildcard: *Attribute: @Wildcard
@*
Examples:xpath=//img[@alt='The image alt text']
xpath=//table[@id='table1']//tr[4]/td[2]
xpath=//a[contains(@href,'#id1')]
Demo
Limitation
Test are sloooooooowReuse browser session
Test are not indipendent
ExpressivenessBuild your own DSL on top of selenium
Beyond Selenium
Get rid of the browser!Framework-dependent approaches (eg:
symfony)
Generic, curl-style basedhttps://github.com/enygma/frisk
