The main aim is to isolate each unit of the system to identify, analyze and fine-tune the defects.  2. What are the Benefits of Unit Testing?   Reduces bugs when transmuting the existing functionality.  Reduces the Cost of Testing as defects are captured in the very early phase.  Ameliorates design and sanctions better refactoring of code. 3. What is the Mockito framework?   Mockito is a mocking framework. It is a Java-based library used to engender simple and basic test APIs for performing unit testing of Java applications. It can additionally be utilized with other frameworks such as JUnit and TestNG.  4. What is mocking? Mocking is primarily utilized in unit testing.

There are several JPA providers, like Hibernate, EclipseLink, or Open JPA which you can utilize. Spring Data JPA is not an implementation or JPA provider, it's just an abstraction used to significantly minimize the quantity of boilerplate code required to implement data access layers for various persistence stores. 3. What Is the Difference Between Hibernate and Spring Data JPA? Hibernate is a JPA implementation, while Spring Data JPA is a JPA Data Access Abstraction. Spring Data offers a solution to GenericDao custom implementations. It can withal engender JPA queries on your behalf t
