Summary

Using @testWith might generate PHP Warning: Uninitialized string offset: 0

Current behavior

You launch phpunit and before you see the header you see 2 Warnings

How to reproduce

This is quite easy. You have to use @testwith in a way that it is followed with a blank line. For example,

/**
 * @testWith		 [1]
 * 			 [2]
 * 			 [3]
 * 
 * @testdox This test should make phpunit spit a PHP Warning !
 */
public function testExample($arg): void
{
	$this->assertIsInt($arg);
}	

This is probably related to the explode("\n", ...) that includes empty lines in between annotations

Expected behavior

No PHP warning.

Workaround

You can move the @testWith statement at the end of the comment section.

/**
 * @testdox This test should NOT make phpunit spit a PHP Warning anymore...
 * 
 * @testWith		 [1]
 * 			 [2]
 * 			 [3]
 */
public function testExample($arg): void
{
	$this->assertIsInt($arg);
}
