Hi Michal, I have fixed the failing test cases of CommonFunctions.class.php. But the following two test files still having issues. - PMA_showMessage_test_disabled.php Test method of this class recursively calling many functions and going through several layers. Since CommonFunctions.class.php having private construct it is not possible to mock the class also. - PMA_checkParameters_test.php When I include the database_interface.lib.php I failed to configure the required configurations. If you have any suggestions let me know. Also is there a method to run all the test cases under /test/libraries/common/ ? Since CommonFunctions.class.php has several test classes it is difficult to genarate the whole class code coverage. *phpunit test/libraries/common/* command won't work.
