A quality gate is the best way to enforce a quality policy in your organization. Quality gates are a integral part of working with SonarQube. They are there to answer the most important question in software development: can I deliver my project to production?
In order to answer this question, a set of conditions is defined based on measure thresholds against which projects are measured. For example:
- No new blocker issues
- Code coverage on new code greater than 80%
- Etc.
Ideally, all projects will be verified against the same quality gate, but that's not always practical. For instance, you may find that:
- Technological implementation differs from one application to another (legacy projects might have different standards).
- You want to ensure stronger requirements on some of your applications (libraries distributed over all your projects might require more strict gates).
- Etc.
Which is why you can define as many quality gates as you wish. Quality Gates are defined and managed in the Quality Gates page found in the top menu of Sonarqube.
To make setting up quality gates more user friendly we introduced a Blueriq quality gate installer which sets up a predefined Blueriq quality gate in sonarqube. This gate can be extended and changed to suit the requirements of your project or projects. How to use the installer is documented on the Quality Gate Installer Guidelines page.
Thanks to the SonarQube notification mechanism, users can be notified when a quality gate fails. How to set up notifications for failing quality gates can be found on the Notifying users of Quality Gate failure page.
