There are currently independent efforts underway to improve the testing for the IMAP and GD extension.

+ | This script runs through all of the phpt tests in the source tree and then compares the function calls in the tests with a complete list of PHP's internal functions. At the end it will tell you if there is a function in PHP that is not mentioned in any test case (I get 415). Thanks to Damien Seguy for this. | ||

+ | ==== Script 3 ==== | ||
+ | This script lists all the classes in PHP and then finds their methods using a ReflectionClass. Using essentially the same logic as the other two scripts teh code searches for tests that refer to these methods. The script is flawed in that many classes have methods of the same name (for example %%__toString%% occurs in many classes), so looking for all tests that refer to %%__toString%% will give a list of mainly irrelevant tests. Because of this I've excluded any method beginning " | ||
