Java is most popular language that is used for enterprise level application development. For such development, development team’s responsibilities are not limited to just writing the code.
There are more to do’s for developers their code. The developers need to follow SDLC methodology such as Agile. Each development sprint cycle starts from technical design, coding, version control, unit testing, code reviews, code static analysis, code compliance and code release.
Deliverables are associated with each of the above tasks. To make the above tasks easier, software tools have been used as a practice. We are going to discuss on which is the best static code analysis tool for Java.
Sonar is the one which is used for most of the Java enterprise applications. Sonar’s objective is to make code quality management accessible to everyone with minimal effort. Minimal effort is something which the developers like the most. They are running on stringent timelines. So, whatever tool takes less time, they will use that tool.
Sonar is now known as SonarQube. It supports analysis of Java in the core. SonarQube also provides code analyzers, reporting tools, hunting modules and TimeMachine. It supports approximately 50 plugins to extend the features based on the code analysis requirements.
Sonar gives a backup for developers to raise their hand when they believe some refactoring is required that would add to enhance the application quality in terms of performance and usability.
SonarQube covers the following code quality aspects to ensure code compliance.
- Duplicated code
- Coding standards
- Unit tests
- Complex code
- Potential bugs
- Design and architecture
SonarQube is very simple and flexible tool and comprised of three components:
1) A set of source code analyzers – Maven plugin containing a set of source code analyzers is used while running Sonar. These analyzers are triggered on demand. Sonar is capable to analyze Maven and non-Maven projects.
2) Support for database engine – Sonar supports 5 database engines, namely Oracle, MySQL, Derby (demo only), PostgreSQL and MS SQLServer. Sonar uses any of the mentioned databases to persist the results of the analysis, the projects and global configuration. It also uses the database engine to keep historical analysis for TimeMachine.
3) A web reporting tool – SonarQube has a user interface to display code quality dashboards on projects, search for defects, check TimeMachine and to configure analysis.
Using SonarQube as code quality management process is worth due to the following advantages.
Helpful in Continuous Inspection process
Sonar helps developer to analyze code, report and take action based on the analysis. It provides dashboards that report on metrics, lists rule based defects. It also provides time machine to “replay past”. It provides customized reports per user and takes control over new issues.
All the above features helps developers to quickly identify code improvements and quick wins, increase developers’ knowledge and understanding of code quality issues and reduce maintenance cost through early identification of code issues.
Sonar can be launched easily in “Continuous Integration” environments as code analysis is run through a Maven plugin.
Internal Quality Assurance and Audits
Sonar provides support for Continuous Inspection process model by enabling real-time notifications when code quality defects are caught in the application. It brings internal quality assurance to the higher level in SDLC (Software Development Life Cycle).
SonarQube offers a number of plugins to perform additional quality metrics. It works seamlessly in the development environment and gives effective results of code governance. The additional plugins help code quality team to rate application quality, perform quantitative analysis and define corrective action.
In the world of software product development, managing source quality looks like the natural next step. SonarQube enables the development team to reach the qualitative objectives with minimal efforts.
