In automation testing, Relative XPath is always preferred over Absolute XPath.
Reasons:
1. Stability Relative XPath survives UI changes. Even if elements are added/removed above the target element, the XPath still works.
2. Shorter and Readable
//input[@id=''username''] vs html/body/div[1]/div[2]/form/div[1]/input
3. Flexible
Supports contains(), starts-with(), text() for dynamic elements.
4. Maintainable Less code to update when the UI changes.
Comparison:
XPATH
-- Preferred (Relative)
//input[@id=''username'']
-- Avoid (Absolute)
html/body/div[1]/div[2]/form/div[1]/input
Exception: Absolute XPath may be used temporarily for debugging but should never be committed to your automation framework.
