ExcessivePublicCount

Since: 0.1

A large number of public methods and attributes declared in a class can indicate the class may need to be broken up as increased effort will be required to thoroughly test it.

Example

public class Foo {
    public $value;
    public $something;
    public $var;
    // [... more more public attributes ...]

    public function doWork() {}
    public function doMoreWork() {}
    public function doWorkAgain() {}
    // [... more more public methods ...]
}

CouplingBetweenObjects

Since: 1.1.0

A class with too many dependencies has negative impacts on several quality aspects of a class. This includes quality criteria like stability, maintainability and understandability

Example

class Foo {
    /**
     * @var \foo\bar\X
     */
    private $x = null;

    /**
     * @var \foo\bar\Y
     */
    private $y = null;

    /**
     * @var \foo\bar\Z
     */
    private $z = null;

    public function setFoo(\Foo $foo) {}
    public function setBar(\Bar $bar) {}
    public function setBaz(\Baz $baz) {}

    /**
     * @return \SplObjectStorage
     * @throws \OutOfRangeException
     * @throws \InvalidArgumentException
     * @throws \ErrorException
     */
    public function process(\Iterator $it) {}

    // ...
}

StaticAccess

Since: 1.4.0

Static access causes unexchangeable dependencies to other classes and leads to hard to test code. Avoid using static access at all costs and instead inject dependencies through the constructor. The only case when static access is acceptable is when used for factory methods.

Example

class Foo
{
    public function bar()
    {
        Bar::baz();
    }
}

Duplicated Code

Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:

Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

Tuning

This issue has a mass of 99.

We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.

The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.

LongVariable

Since: 0.2

Detects when a field, formal or local variable is declared with a long name.

Example

class Something {
    protected $reallyLongIntName = -3; // VIOLATION - Field
    public static function main( array $interestingArgumentsList[] ) { // VIOLATION - Formal
        $otherReallyLongName = -5; // VIOLATION - Local
        for ($interestingIntIndex = 0; // VIOLATION - For
             $interestingIntIndex < 10;
             $interestingIntIndex++ ) {
        }
    }
