Regression testing is the process of retesting a software application to ensure that new code changes have not adversely affected existing functionality.

• Regression testing is performed after code changes to verify that the existing functionality still works as expected.

• It helps in identifying any defects introduced by new code changes.

• Regression testing can be automated to save time and effort.

• Examples of regression testing tools include Selenium, JUnit, and TestNG.

final is a keyword used in Java to declare constants, while finally is a block used in exception handling to execute code regardless of an exception.

• final is used to declare constants in Java, meaning the value cannot be changed once assigned

• finally is a block used in exception handling to execute code regardless of an exception being thrown

• Example: final int MAX_VALUE = 100; try { // code that may throw an exception } finally { // code to be executed regardless of exception ...read more
