问题 I'm having a problem with a tester that my application crashes in initialization. I added more logging and exception handling but it still crashes with the generic "this program has stopped working" message rather than triggering my error handling.

问题 According to the PHPUnit Documentation on @expectedExceptionMessage , the string must only be a substring of the actual Exception thrown. In one of my validation methods, an array item is pushed for each error that occurs, and the final Exception message is displayed by imploding the array of errors. class MyClass { public function validate($a, $b, $c, $d) { if($a < $b) $errors[] = "a < b."; if($b < $c) $errors[] = "b < c."; if($c < $d) $errors[] = "c < d."; if(count($errors) > 0) throw new

问题 Does anyone know how to check that an exception is raised correctly? I need something that works in Python 2.7.
