Testing

The purpose of this page is to collect values for use in automated testing. The focus is PHP, so there are only signed integers.

Outliers

• null
• true, false
• ~0, ~1
• '', 'true', 'false', 'yes', 'no', 'maybe', '-1', '0', '1', '0.0', '0.1', '1.0'

• []
• [ null ]
• [ true, false ]
• [ ~0, ~1 ]
• [ '', 'true', 'false', 'yes', 'no', 'maybe', '-1', '0', '1', '0.0', '0.1', '1.0' ]
• [ new stdClass(), new DateTime() ]
• [ 'a' => null ]
• [ 'a' => true, 'b' => false ]
• [ 'a' => ~0, 'b' => ~1 ]
