As a result, the JavaScript plugin should be updated. Finally, every project will receive an overall quality label based on elements such as the number of bugs, code smells, test coverage, and code duplication. It can pick up, as a preliminary to check-in, errors and weaknesses in code that can happen incidentally to even the most experienced developer. The official SonarQube documentation defines a code smell as: “Smelly” code does (probably) what it should, but it will be difficult to maintain. In order to analyze JavaScript code, you need to have Node.js >= 8 installed on the machine running the scan. The cool thing about SonarQube is that it indicates the number of lines that aren’t covered by tests. Istanbul can output an lcov.info file that can be used by the sonar-runner. If for some reason analysis of files in these directories It’s possible to expand the bugs and examine the affected lines. Sonar scanner read lcov.info file from coverage folder to publish code quality & code coverage to Sonar Dashboard. The CI/CD pipeline would push your code to the SonarQube … SonarQube's JavaScript static code analysis detects Bugs, Security Hotspots, and Code Smells in JavaScript code for better Reliability, Security, and Maintainability Since SonarQube 6.2, the concept of coverage type (unit/IT/overall) was dropped.

Preparation Sonarqube Sonarqube can be built quickly using the docker version. You’ve finished the setup! Last week we had sonarqube code coverage. Introduction. SonarQube JavaScript Features SonarQube performs static code analysis for almost any type of project. Here, we are going to discuss integrating SonarQube with Jenkins to perform code analysis. It's possible to integrate a JavaScript project into Sonar by using Istanbul's instrumentation. The simplest way to use sonarqube to scan JavaScript code and analyze code quality is to use the default rules of sonar-way and sonar-scanner to scan. Static code analysis is a method for identifying bugs and other quality issues in the program by examining the source code without actually running it. This property will exclude the files also for other languages, similar to sonar.exclusions property, however sonar.exclusions property should be preferred to configure general exclusions for the project. You can clone the code locally through this link or use your own project. However, the goal of SonarQube has changed over the years. It uses the most advanced techniques (pattern matching, dataflow analysis) to find Code Smells, Bugs, and Security Vulnerabilities. In this section, we want to configure a SonarQube JavaScript project. This is achieved by scanning the codebase and tracing code paths to find common code smells, potential bugs, tech debt (e.g., duplicate code), unit test coverage, and code logic complexity. The JavaScript Analyzer parses the source code, creates an Abstract Syntax Tree (AST) and then walks through the entire tree. To explore a part of the AST, override the required method(s). You can see the mirror collated by Easypack. It’s important to emphasize that coverage at the code level does not guarantee that the software is bug-free, not even the most demanding one. 4. Let’s continue by running the scanner. When the runtime is SonarQube 6.2+: log a warning when property sonar.javascript.lcov.itReportPath is used Is it possible to exclude js files from it? I have my JavaScript coverage all working with Karma and other tools. SonarQube reports can show the test coverage, you just need to run tests before analysis and turn on the coverage flag ; Conclusion. It is language-agnostic and can be installed on premises, and you can integrate it easily with Buddy. The scanner results page shows the overall quality label. The command holds the generated token (Dsonar.login field) to access the SonarQube GUI to upload the results. If standard node is not available, you have to set property sonar.nodejs.executableto an absolute path to Node.js executable. It didn’t find any security vulnerabilities.
