fix tests without assertion
switch to strict tests, log results in tap format
remove global constant tests, ok if it works but not officially supported
remove old file name prefix
split classes into separate files
can't use data with closures with process isolation, as PHPUnit serializes the data but closures are not serializable
fix group
rename for more clarity
use tilde operator instead of wildcard, enhances forward compatibility
