Warranty as per Section 12 of Sale of Goods Act, 1930, is:

Section 12(3) of the Sale of Goods Act defines a warranty as a stipulation "collateral to the main purpose of the contract", whose breach gives a claim for damages but not a right to reject the goods and treat the contract as repudiated. A stipulation essential to the main purpose is a condition under section 12(2), so a warranty is neither the same as a condition nor a ground for repudiation.
