CakePHP fatal error: Class 'ErrorHandler' not found

Question

I've generated testsuits via "cake bake testsuit" and used localhost/test.php for my app. So, the is an error when I tried to run one of test (else tests are valid):

Fatal error: Class 'ErrorHandler' not found in Z:\home\prodvigator\www\cake\libs\object.php on line 201

This models and controllers are generated by scaffold and I don't think that an error is in this sources.

Using: CakePHP 1.3 The latest SimpleTest

Answer 1

In my case, deleting all the files in the folder /app/tmp/cache/persistent solved the problem.
