Code Inspection: Assertion can be replaced with 'assertEmpty/assertNotEmpty'

Reports the assertTrue/assertFalse usages that can be replaced with assertEmpty/assertNotEmpty in PHPUnit tests.

See assertEmpty (phpunit.readthedocs.io) for details.

In the following example, asserting whether the $arr array is empty is initially performed by providing the empty() and count() functions calls as the conditions for the assertTrue method. After the quick-fix is applied, the more specific assertEmpty and assertNotEmpty are used directly on the $arr array.

class Test extends \PHPUnit\Framework\TestCase { public function doTestTrue() { $arr = ["a", "b", "c"]; $this->assertTrue(empty($arr)); $this->assertTrue(count($arr) <= 0); $this->assertTrue(count($arr) != 0); } }
class Test extends \PHPUnit\Framework\TestCase { public function doTestTrue() { $arr = ["a", "b", "c"]; $this->assertEmpty($arr); $this->assertEmpty($arr); $this->assertNotEmpty($arr); } }
