Fixer could be risky if one is overriding PHPUnit's native methods.

This rule is CONFIGURABLE

List of assertion methods to fix.

Allowed values: a subset of ``['assertEquals', 'assertNotEquals', 'assertNotSame', 'assertSame']``

Default value: ``['assertEquals', 'assertNotEquals', 'assertNotSame', 'assertSame']``

Examples

Example #1
~~~~~~~~~~

*Default* configuration.

.. code-block:: diff

   --- Original

    <?php
    final class FooTest extends \PHPUnit_Framework_TestCase {
        public function testSomething() {
   -        $this->assertEquals(false, $b);
   -        $this->assertSame(true, $a);
   -        $this->assertNotEquals(null, $c);
   -        $this->assertNotSame(null, $d);
   +        $this->assertFalse($b);
   +        $this->assertTrue($a);
   +        $this->assertNotNull($c);
   +        $this->assertNotNull($d);
        }
    }

Example #2

With configuration: ``['assertions' => ['assertSame', 'assertNotSame']]``.

.. code-block:: diff

   --- Original

        public function testSomething() {
            $this->assertEquals(false, $b);
   -        $this->assertSame(true, $a);
   +        $this->assertTrue($a);
            $this->assertNotEquals(null, $c);
