Is SonarQube Replacement for Checkstyle, PMD, FindBugs?
By default, for Java projects, Sonar executes FindBugs, CheckStyle, and PMD, as well as a few other “plugins”, such as Cobertura. The main advantage is that it stores the history in a database. Sonar uses these three tools as plugins and the data from all three of these tools is applied with a value that displays graphs.
How is the architecture of the SonarQube?
The main engine of the SonarQube platform is known as Squid. This engine is supported by extra code analyzers that SonarQube organizes together to measure the quality of the code. SonarQube architecture, comprises mainly four components:
13) List out what are the build phases in Maven?
7) Why Maven Plugins are used?
1 Explain the term RULES with respect to SonarQube?
SonarQube runs rules on source code to create issues. There are four types of rules:
1 Can you execute SonarQube on your own server?
Yes, one can host SonarQube on their own server. However, it is suggested to use a hosted version of SonarQube.
Explain why does SonarQube need a database
SonarQube needs to communicate with the database to save the results of the analysis. The SonarQube Runner needs to interact with both the web server and the database and is suggested as the default launcher to analyze a project with SonarQube. This means all the passwords should be stored in the database.
16) Explain what would the “jar: jar” goal do?
jar: jar will not recompile sources; it will imply just create a JAR from the target/classes directory considering that everything else has been done
2 Explain if SonarQube is a replacement for Checkstyle, PMD, and FindBugs ?
Sonar executes CheckStyle, FindBugs, and PMD, as well as a few other “plugins”, such as Cobertura on default for Java projects. The main advantage is that it stores the history in a database. Sonar uses these three tools as plugins and collates the data from all three by giving additional value by displaying graphs and such from these tools. Thus, they are complementary to sonar.
1) Explain what is Maven? How does it work?
Maven is a project management tool. It provides the developer a complete build lifecycle framework. On executing Maven commands, it will look for POM file in Maven; it will run the command on the resources described in the POM.
1 Which of the following statements is correct?
Correct Answer: The correct statement is Sonar executes CheckStyle, FindBugs and PMD by default for Java projects.
1 Explain, what are the prerequisite for SonarQube Installation
Following are the prerequisites for SonarQube Installation
A block hole concept in the data flow diagram can be defined as “A processing step may have input flows but no output flows”.In a black hole, data can only store inbound flows.
Software Reverse Engineering is a process of recovering the design, requirement specifications, and functions of a product from an analysis of its code. It builds a program database and generates information from this. The purpose of reverse engineering is to facilitate maintenance work by improving the understandability of a system and producing the necessary documents for a legacy system.
For more details, please refer to the following article Types of Feasibility Study in Software Project Development article.
A baseline is a measurement that defines the completeness of a phase. After all activities associated with a particular phase are accomplished, the phase is complete and acts as a baseline for next phase.
It is a process of software development that is done to improve the maintainability of a software system.
