What is SonarQube?
•       Sonar is a web based code quality analysis tool for Maven based Java projects. It covers a wide area of code quality check points which include: Architecture & Design, Complexity, Duplications, Coding Rules, Potential Bugs, Unit Test etc.

Why use SonarQube?
•       Sonar covers the 7 sections of code quality Architecture and Design
•       Unit tests
•       Duplicated code
•       Potential bugs
•       Complex code
•       Coding standards
•       Comments

What is role of database in SonarQube?
•       Sonar uses a Derby or H2 as default database. When running Sonar, it says that these databases may only be used for evaluation. We can change this default database and use our custom DB.

Mockito interview Questions

1.       Question 1. What Is Mockito? Answer : Mockito allows creation of mock object for the purpose of Test Driven Development and Behavior Driven development. Unlike creating actual object, Mockito allows creation of fake object (external dependencies) which allows it to give consistent results to a given invocation. 2.       Question 2. Why Do We Need Mockito? What Are The Advantages? Answer : Mockito differentiates itself from the other testing framework by removing the expectation beforehand. So, by doing this, it reduces the coupling. Most of the testing framework works on the "expect-run-verify". Mockito allows it to make it "run-verify" framework. Mockito also provides annotation which allows to reduce the boilerplate code. 3.       Question 3. Can You Explain A Mockito Framework? Answer : In Mockito, you always check a particular class. The dependency in that class is injected using m...

REST Methods

GET ============================================= HTTP GET method is used to **read** (or retrieve) a representation of a resource. According to the design of the HTTP specification, GET requests are used only to read data and not change it. Therefore, when used this way, they are considered safe. That is, they can be called without risk of data modification or corruption. Means calling it once has the same effect as calling it 10 times. Additionally, GET is idempotent which means that making multiple identical requests ends up having the same result as a single request. Donot expose unsafe operations via GET. It should never modify any resources on the server. Example: ------------    GET http://www.example.com/customers/12345/orders POST =================================== -> The POST verb is most-often utilized to **create** new resources. In particular, it's used to create subordinate resources. -> That is, subordinate to some other (e.g. parent) reso...
