• Functional testing verifies if the software meets functional requirements

• Regression testing ensures that changes to the software do not break existing functionality

• Functional testing is done before regression testing

• Regression testing is done after changes are made to the software

• Functional testing is done manually or with automation tools

• Regress...read more
