Introduction
SonarQube inspects the quality of code of applications and it is an open-source platform that supports multiple databases. We can check the health status of an application for multiple languages like C, C++, Java, PHP, C#, and many web languages including HTML, CSS, and JavaScript.
SonarQube can easily be integrated with Gradle, Ant, Maven, Active directory, Github, and LDAP and can detect bugs that display results on the dashboard.
