Overview

The Quality Profiles service is the heart of SonarQubeTM as , since it is where you define your requirements on:

...

 by defining sets of coding rules

...

 (ex:

...

Methods must not have a complexity greater

...

than 10)

...

You .

Ideally, all projects will be measured with the same profile for any given language, but that's not always practical. For instance, you may find that:

  • Technological implementation differs from one application to another (for example, different coding rules may apply when building threaded or non-threaded Java applications).
  • You want to ensure stronger requirements on some of your applications (internal frameworks for example).
  • Etc.

Which is why you can define as many quality profiles as you want. Indeed, the requirements are usually not the same while developing an application from scratch or maintaining an application which is 10 years old, while developing a technical framework or a web application. Then you can associate several quality profiles (one per language) to each project.To wish. To manage quality profiles, go to Quality Profiles (top bar), where you'll find profiles grouped by language:

Security

The Quality Profiles service can be accessed by any users (even anonymous users) but any changes (create, edit or delete) require to be logged in as a System administrator or a Quality Profile administrator (since version 3.6).

A project administrator can only change the quality profiles associated to its project(s). See Project Administration.

Creating Profile

To create a quality profile, click on the Create button on the upper right and enter the name of the quality profile:

You can optionally provide some Checkstyle, PMD and Findbugs configuration files to fill the new quality profile with some existing rules configurations.

Editing Profile

Configuring Rules

Go to the Coding rules tab. As there are numerous available coding rules, a search engine is available:

A coding rule can be activated or deactivated. Its severity and parameters can be modified:

Some bulk change actions are available to quickly activate or deactivate a set of rules:

Note

No extra validation action is required to make changes to the quality profile.

Status of Rule

Since version 3.6, to help you choose which coding rules to activate, each rule has a status:

  • Beta: The coding rule has been recently implemented and we haven't get enough feedback from users yet. So, it may log some false positives or generate some false negatives.
  • Deprecated: The coding rule should no longer be used as a similar one, more powerful and accurate, exists.
  • Ready: The rule is ready to be used in production.

Date of Creation of Rule

Since version 3.6, to help you spot the new coding rules, each rule has a creation date:

Multiple Activations of a Rule

Some coding rules can be activated multiple times in the same quality profile with different parameters values. XPath rule is one of this kind.

If a rule can be activated multiple times, a Copy button is available:

Clicking on the Copy rule link displays a form to define the new rule:

Once the new rule has been created, it can be managed as any other rules.

Editing Alerts

...

  • the metric you are interested in
  • whether the alert will be checked against the current value of the measure or the variation of this measure (available since version 3.4)
  • an operator (is greater than, is less than, etc.)
  • the value that will trigger a warning
  • the value that will trigger an error

Any changes will apply during the next analysis.

Profile Inheritance

Maintaining lots of quality profiles over time can be tedious. To ease this maintenance, quality profiles can be inherited. For each profile, you can decide whether it has a parent profile or not on the Profile Inheritance tab:

Image Removed

This means that the quality profile inherits from all the coding rules defined in the parent one. This is shown on the Coding rules tab by a small blue marker next to the coding rule:

A rule inherited from a parent cannot be deactivated. But it is possible to change its parameter(s) and/or its severity. As soon as one of these values is changed, a red marker replaces the blue marker:

Note

Alerts are not inherited from parent profiles.

Extending Rule Description

  • Extend the description of a rule to give more details, add an internal description, etc. This is going to be attached to the rule in every quality profile and will also be available when clicking on an issue:

...

  • Add a comment, in the context of a specific quality profile, explaining the reasons of the activation of the rule, it severity, etc.

Associating Project to Quality Profile

To associate/dissociate projects to/from a quality profile, go to the Projects tab:

...

Backuping/Restoring Profile

This backup/restore mechanism is useful for instance to promote a quality profile from a staging environment to a production one or to share quality profiles with subcontractors.

Click on the Backup button to export an XML file.

To restore a quality profile, click on the Restore profile link on the top right of the Quality profiles page, choose the XML file to restore and click on the Restore profile button: Image Removed

Copying Profile

In order to copy an existing quality profile, click on the Copy button next to the profile you want to copy. You are prompted to give the name of the new profile. The profile is the exact copy of the copied one. You can then make desired changes to the new quality profile.

Renaming Profile

Click on the Rename button. You are prompted to give the new name of the profile.

Deleting Profile

Click on the Delete button. You are prompted to confirm the deletion.
Deleting a quality profile will delete the alerts defined in the profile and will remove the association with projects. If nothing else is done, the default profile is used to perform the next analysis on the (ex-)associated projects.

Comparing Profiles

It is possible to compare 2 quality profiles to understand the differences between them:

The comparison service shows all differences (rules in one profile but not in the other, parameters differences, etc.):

Profile Change Log

Every time a change is made to a quality profile, it is going to appear in the change log:

Extending Coding Rules

Custom coding rules can be added. See Extending Coding Rules for detailed information and tutorials.

Image Added

 

Each language must have a default profile (marked with a green check). Projects that are not explicitly associated with a specific profile, and which do not have a sonar.profile analysis property will be analyzed using the language's default profile.

Security

The Quality Profiles service can be accessed by any user (even anonymous users). All users can view every aspect of a profile. That means that anyone can see which rules are included in a profile, and which ones have been left out, see how a profile has changed over time, and compare the rules in any two profiles.

To make rule profile changes (create, edit or delete) users must be granted the Administer Quality Profiles and Gates permission.

A project administrator can choose which profiles his project is associated with. See Project Administration for more.
