h3. Why Code Quality Matters

* Your code is your asset
* Keeps your cost down as you grow
* Increase robustness, maintainability, security, performance, scalability, extensibility, etc.
* Prevention is the best medicine

h3. Challenges with Code Quality

* Often talked about in theory but not actually practiced
* Hard to measure or prove
* Difficult to plan and prioritize

h3. Sonar -- Quality Management Platform

[http://www.sonarsource.org/]

* Open source and extensible
* Manages code quality with
** Views of all projects at a glace, drill down to source code, differential, hotspots
** Coding Rules
** Unit Tests
** Standard Metrics
** Time Machine
** Integration with tools such as PMD, Findbugs, Checkstyle, JSLint, Clover, Cobetura, Hudson (many plugins available)

h3. Static Code Analysis (SCA)

* Applies rules to find potential bugs, anti-patterns, and code style violations
* Catches problems as early as possible in the development process
* A well-established industry practice for validating the quality of source code
* Can be automated and tracked by tools like Sonar

# Copy bb-pmd-rules.jar and bb-rules-sonar.xml files to $\{Sonar_Home}/extensions/rules/pmd
# Make sure the files have read rights for Sonar
# Restart Sonar server
# Verify that Bb\* rules exist from a Java profile's coding rules list

How to use Blackboard's Java rule set:
# Log in to Sonar as a user with Administrators role
# Navigate to "Configuration" \-> "Quality Profiles"
# Click on "Restore profile" link located on the top right of the page
# Select bb-sonar-profile-java.xml and click on "Restore profile" button
# Specify the Sonar analysis configuration to use the restored profile
