Explain but for test for contract damage under English law.

Under English law, a contract breach is a breach of the terms of a contract between two or more parties. A breach can occur when one party fails to fulfill its obligations under the contract, or when one party does something that goes against the terms of the contract. In order to prove that a breach of contract has occurred, the party claiming the breach must show that: (1) there was a valid contract; (2) the other party failed to perform its obligations under the contract; and (3) the breach caused the claimant to suffer damage. If all of these elements are met, the claimant may be entitled to monetary damages or other relief from the breaching party.
