This li₃ plugin adds code quality assurance to your toolbelt.

Key Features

  • Detect coding-standard violations.
  • Find weak- or untested classes/methods.
  • No external dependencies.
  • Color-Highlighting.
  • Integrates into the Lithium test dashboard.
  • Runs on Windows without hassle.
  • Cool shortcuts to ease your workflow.


The preferred installation method is via composer. You can add the library as a dependency via:

composer require unionofrad/li3_quality

li₃ libraries must be registered within your application bootstrap phase as they use a different (faster) autoloader.


If you open the test dashboard (under /test in your browser), you should have an additional Syntax button to check the files directly in your browser.

Usage: The "syntax" command

If you just run it with li3 syntax, it will run all rules against your app library.

$ li3 syntax --verbose path/to/code

33      -               Protected Method "foobar" does not start with "_"

Usage: The "fix" command

The fix command helps in migrating code to newer versions. It'll rewrite existing source code files and update them in place. Please note that you should use a version control system when using this command, as the results may not always be 100% what you'd expect.

$ li3 fix --verbose path/to/code

Custom Rules & Rule Sets

Rule based commands (syntax and fix) will work only with a rule set configuration file. If none is provided through the --config=<FILE> option, these commands fall back to use the default configuration files in config/syntax.json and config/fix.json respectively.

Custom rules must be create as i.e. <your library>/extensions/qa/rules/{syntax,fix}/YourCustomRule.php.

GIT Pre Commit Hook

This pre commit hook is based upon the example found in .git/hooks/pre-commit.sample. Copy the sample script to /path/to/project/.git/hooks/pre-commit and make it executable. Then, replace the code in the script with the code shown below and adjust the paths to the plugin and the li3 command.

cd /path/to/project
cp .git/hooks/pre-commit.sample .git/hooks/pre-commit
chmod a+x .git/hooks/pre-commit

Now add the following code to .git/hooks/pre-commit and adjust the APP and LI3 values.



if git-rev-parse --verify HEAD >/dev/null 2>&1
    # Initial commit: diff against an empty tree object


for FILE in `git diff-index --cached --name-only --diff-filter=AM ${AGAINST}`
    cd ${APP} && ${LI3} syntax ${PROJECT}/${FILE}
    test $? != 0 && EXIT_STATUS=1


Now when committing each file the syntax is checked. The commit is aborted if a check failed. If you don't want to have the hook run on commit pass the --no-verify option to git commit.

Usage: The "coverage" command

With li3 coverage you can get a summary of how well your classes are covered with tests. This makes use of some xdebug functions, so make sure to have it installed.

$ li3 quality coverage
Lithium Code Coverage
Checking coverage on 6 classes.
   no test |     n/a | app\models\Authors
   no test |     n/a | app\models\Groups
   no test |     n/a | app\models\Posts
   no test |     n/a | app\controllers\HelloWorldController
   no test |     n/a | app\controllers\PagesController
   no test |     n/a | app\controllers\PostsController

You can also reuse the --library argument as well. In addition, this command provides an optional --threshold argument that only displays coverage below the given amount. This defaults to 100, so all classes will be shown. If you have coloring on your shell (likely not on windows), then the classes are colored to reflect the coverage policy of the Lithium framework (0% or no test is red, 85% or higher is green and the rest is yellow).
