Answer 21: This entirely boils down to operations you are carrying out with Selenium. Though you would definitely be using following Selenium Commands more often –

• Open: opens a web page.
• click/clickAndWait: click on an element and waits for a new page to load.
• Select: Selects a value from a drop down value.
• verifyTitle/assertTitle: verifies/asserts page title.
• verify/assert ElementPresent: verifies/asserts presence of element, in the page.
• verify/assert TextPresent: verifies/asserts  expected text is somewhere on the page.

Answer 22: Html id and name can be used as it is in selenium IDE.

For example Google search box has name – “q” and id – “list-b” and they can be used as target in selenium IDE

Answer 23: XPath is a way to navigate in xml document and this can be used to identify elements in a web page. You may have to use XPath when there is no name/id associated with element on page or only partial part of name/id is constant.

• Direct child is denoted with - / 
• Relative child is denoted with - // 
• Id, class, names can also be used with XPath –
•  //input[@name=’q’]
• //input[@id=’lst-ib’]
• //input[@class=’ lst’]

If only part of id/name/class is constant than “contains” can be used as –

• //input[contains(@id,'lst-ib')]
