please see SpacePossum@3d7875c as well

[SpacePossum]

please add:

             [
                 '<?php $this->assertInternalType(\'array\', $a,);',
                 '<?php $this->assertTrue(is_array($a,),);',
             ],

as these are fixed through a different path

@SpacePossum I've added your test cases

[SpacePossum]

please add this test as well:

            [
                '<?php $this->assertNan($y  , );',
                '<?php $this->assertTrue(is_nan($y)  , );',
            ],

I think your change aims to remove the trailing , or at least remove the trailing spacing, but it seems not. Maybe removing the trailing space before removing the , token is the cause?

I'm happy with results anyway, but like to capture the behavior of the fixer in this test case :)
