unit testing - Is it necessary to create mocks for all table classes in every PHPUnit test method in Zend Framework 2? -

-

i have complete running application , want write tests it. i've started application module , following manual. i'm writing "first controller test" , expected getting error:

1) applicationtest\controller\indexcontrollertest::testindexactioncanbeaccessed zend\servicemanager\exception\servicenotfoundexception: zend\servicemanager\servicemanager::get unable fetch or create instance zend\db\adapter\adapter

the error says service manager can not create instance of database adapter us. database adapter indirectly used our album\model\albumtable fetch list of albums database.

...

the best thing mock out our album\model\albumtable class retrieves list of albums database.

when i'd follow manual now, i'd have create mocks / many tables of application in every test method or @ least in every setup():

1) applicationtest\controller\indexcontrollertest::testindexactioncanbeaccessed zend\servicemanager\exception\servicenotfoundexception: zend\servicemanager\servicemanager::get unable fetch or create instance zend\db\adapter\adapter  /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:456 /path/to/project/module/catalog/module.php:56 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:737 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:869 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:494 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:441 /path/to/project/module/catalog/module.php:51 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:737 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:869 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:494 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:441 /path/to/project/module/cache/module.php:58 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:737 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:869 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:494 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:441 /path/to/project/module/search/module.php:61 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:737 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:869 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:494 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:441 /path/to/project/module/search/module.php:81 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:737 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/abstractpluginmanager.php:205 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:494 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/servicemanager.php:441 /path/to/project/vendor/zendframework/zendframework/library/zend/servicemanager/abstractpluginmanager.php:103 /path/to/project/vendor/zendframework/zendframework/library/zend/view/renderer/phprenderer.php:378 /path/to/project/vendor/zendframework/zendframework/library/zend/view/renderer/phprenderer.php:397 /path/to/project/module/application/view/layout/layout.phtml:76 /path/to/project/module/application/view/layout/layout.phtml:76 /path/to/project/vendor/zendframework/zendframework/library/zend/view/renderer/phprenderer.php:507 /path/to/project/vendor/zendframework/zendframework/library/zend/view/view.php:205 /path/to/project/vendor/zendframework/zendframework/library/zend/mvc/view/http/defaultrenderingstrategy.php:126 /path/to/project/vendor/zendframework/zendframework/library/zend/eventmanager/eventmanager.php:472 /path/to/project/vendor/zendframework/zendframework/library/zend/eventmanager/eventmanager.php:207 /path/to/project/vendor/zendframework/zendframework/library/zend/mvc/view/http/defaultrenderingstrategy.php:136 /path/to/project/vendor/zendframework/zendframework/library/zend/eventmanager/eventmanager.php:472 /path/to/project/vendor/zendframework/zendframework/library/zend/eventmanager/eventmanager.php:207 /path/to/project/vendor/zendframework/zendframework/library/zend/mvc/application.php:332 /path/to/project/vendor/zendframework/zendframework/library/zend/mvc/application.php:307 /path/to/project/vendor/zendframework/zendframework/library/zend/test/phpunit/controller/abstractcontrollertestcase.php:255 /path/to/project/module/application/test/applicationtest/controller/indexcontrollertest.php:41

can recomended approach? should create mocks in 1 place , "include" them somehow? don't get, how handle in general.

you create mock of objects need inject in test. in example, create mock of dbtable can control database interaction , not dependent on setting sort of database (making test more brittle).

you need services required testing specific action in controller. each of actions should not interacting many services each test should have couple of mocks in in order run.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
