Rule php_unit_data_provider_static

Data providers must be static.

Warning

Using this rule is risky

Fixer could be risky if one is calling data provider function dynamically.

Configuration

force

Whether to make the data providers static even if they have a dynamic class call (may introduce fatal error “using $this when not in object context”, and you may have to adjust the code manually by converting dynamic calls to static ones).

Allowed types: bool

Default value: false

Examples

Example #1

Default configuration.

--- Original

-    public function provideSomethingCases() {}
+    public static function provideSomethingCases() {}
 }

Example #2

With configuration: ['force' => true].

     /**
      * @dataProvider provideSomethingCases1
      * @dataProvider provideSomethingCases2
      */
     public function testSomething($expected, $actual) {}
-    public function provideSomethingCases1() { $this->getData1(); }
-    public function provideSomethingCases2() { self::getData2(); }
+    public static function provideSomethingCases1() { $this->getData1(); }
+    public static function provideSomethingCases2() { self::getData2(); }
 }

Example #3

 class FooTest extends TestCase {
     /**
      * @dataProvider provideSomething1Cases

     public function provideSomething1Cases() { $this->getData1(); }
